− - "Owner-furnished keying plan (existing system, match existing keyway)"
−default: "Grand master key system (GMK) — master + grand master hierarchy"
−```
−
−### The keying system shall be designed by the hardware consultant in coordination with the Owner before cylinder orders are placed.
−
−### The hardware consultant shall confirm that the keying system has sufficient theoretical key change capacity for the project's door count and anticipated future expansion.
−
−### The keying system establishes the hierarchy of key access across the building — which keys open which doors — and determines the mechanical keyway and cylinder line required to support the system. {note}
−
−### The grand master key system is the appropriate default for medium and large commercial buildings with multiple departments or zones requiring independent change keys; in a grand master system, department keys open only the doors within that department, master keys open all doors in a group, and the grand master key opens all doors. {note}
−
−## Construction Keying {toc}
−
−```datasheet
−label: Construction Keying Required
−type: radio
−options:
− - "Yes — construction keying cores provided, replaced at owner acceptance"

−
−### At substantial completion or at Owner acceptance, the construction cores shall be replaced with the permanent keyed cores matching the Owner's keying plan.
−
−### Construction cores shall be of the interchangeable core type to facilitate rapid replacement.
−
−### All construction keys shall be collected and returned to the hardware supplier or Owner before the construction cores are removed.
−
−### Construction keying provides a common temporary key for all cylinders during the construction period, allowing the general contractor and subcontractors to access all areas without distributing permanent keys; construction keys left in circulation after construction is complete represent a security vulnerability. {note}
−
−## Key Control {toc}
−
−```datasheet
−label: Key Control Cabinet Required
−type: radio
−options:
− - "Yes — Owner-provided key control cabinet and key tags specified"

− - "Match existing — confirm keyway with Owner"
−default: "Proprietary keyway — restricted, manufacturer-controlled, limited duplication"
−```
−
−### Cylinders shall be provided with the keyway specified by the hardware consultant to match the Owner's existing keyway or, for new buildings, to establish a proprietary keyway that cannot be easily duplicated without authorization from the Owner.
−
−### For organizations with multiple facilities or existing key systems, the Owner shall confirm the keyway requirement, because matching the existing keyway is more important than proprietary status.
−
−### Proprietary keyways provide the highest level of key control because key blanks are not available through general locksmith channels. {note}

−
−### Gaps larger than permitted at fire-rated assemblies shall be corrected, because they allow flames and hot gases to bypass the door.
−
−### For fire-rated assemblies, the undercut (bottom clearance) shall comply with the listing requirements and shall not exceed the maximum permitted by the listing, and NFPA 80 limits the bottom clearance for fire-rated assemblies in corridors to 3/4 in. maximum.
−
−### Where an automatic door bottom is specified, the drop distance and the compressed seal thickness shall be confirmed so that the door bottom provides continuous contact with the threshold or floor when the door is closed.

+# Scope {toc}
+
+## This standard governs the furnishing and installation of swinging door openings supplied as one combined package: hollow metal doors and frames, architectural wood flush doors, and the finish hardware that operates them. {note}
+
+## A door opening is a single assembly whose leaf, frame, hardware, gasketing, glazing, and threshold are dimensioned and prepared for one another. Nothing in the opening can be selected in isolation, and in a fire-rated opening the parts must have been tested together and carry a label as a set. {note}
+
+## The furnished work shall comprise the door leaves, the frames, the finish hardware, the frame anchors, the gasketing and thresholds, and the factory preparations that join them.
+
+## The Contractor shall reconcile the hollow metal, wood door, and hardware submittals against one another before any product is released for fabrication.
+
+## The following are outside the furnished work and are established by other standards: access control controllers, readers, credentials, and system programming, governed by [[sync/access-control-systems]]; fire alarm initiating and notification equipment and the relays that release hold-open devices, governed by [[sync/fire-alarm-systems]]; the partitions and wall assemblies that receive the frames, governed by [[sync/gypsum-board-assemblies]] and [[sync/unit-masonry]]; field painting of doors and frames, governed by [[sync/interior-painting]] and [[sync/exterior-painting]]; and glazing materials set into leaves and frames, governed by [[sync/glazing]] and [[sync/fire-rated-glazing]]. {note}
+
+## The Contractor shall coordinate frame installation with the wall trades so that anchor type, anchor spacing, and wall build sequence are settled before frames are delivered.
+
+## The Contractor shall coordinate electrified hardware with the access control installer and the electrical installer so that raceway, power, and control conductors reach each opening before hardware is set.
+
+# Referenced Standards {toc}
+
+## Products, fabrication, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited.

+# Quality Assurance {toc}
+
+## Authorship of the Hardware Schedule {toc}
+
+### The hardware sets, the keying hierarchy, and the review of the hardware submittal are the work of one identified party, and that party shall be established in the datasheet.
+
+```datasheet
+label: Hardware Schedule Prepared By
+type: select
+options:
+ - "A hardware consultant retained by the Owner"
+ - "The Architect of Record"
+ - "The hardware supplier's certified consultant"
+ - "The door and hardware package supplier"
+```
+
+### The party identified in the datasheet shall prepare or review every hardware set and shall be the reviewer of record for the hardware submittal.
+
+### The hardware sets shall be prepared or reviewed by a person holding a current Architectural Hardware Consultant credential from the Door Security and Safety Foundation, or by a person who submits equivalent evidence of qualification acceptable to the Architect.
+
+### Where the parties disagree whether a proposed hardware item satisfies a set, the Architect shall make the initial determination.
+
+## Fabricator and Supplier Qualifications {toc}
+
+### Hollow metal doors and frames shall be produced by a fabricator that manufactures products conforming to ANSI/SDI A250.8 as a regular part of its business and that submits records of comparable completed production.
+
+### Wood doors shall be produced by a manufacturer that produces doors conforming to ANSI/WDMA I.S. 1A as a regular part of its business and that submits records of comparable completed production.
+
+### For every fire protection rating required on the project, the door fabricator, the frame fabricator, and the wood door manufacturer shall each hold a current, active listing from a nationally recognized testing laboratory covering the assembly configurations to be furnished.
+
+### Hardware shall be furnished by a supplier authorized by each manufacturer whose products it supplies, and the supplier shall produce evidence of that authorization on request.
+
+## Opening Mock-Up {toc}
+
+### Where the datasheet requires a mock-up, the Contractor shall install it at a location acceptable to the Architect and shall not proceed with the corresponding production work until the mock-up is accepted in writing.
+
+```datasheet
+label: Opening Mock-Up
+type: select
+options:
+ - "No mock-up required"
+ - "One typical interior opening"
+ - "One exterior opening"
+ - "One fire-rated opening"
+ - "One opening of each door type used in the work"
+default: "No mock-up required"
+```
+
+### The mock-up shall demonstrate leaf and frame fit, hardware function and mounting heights, gasketing contact, threshold and sill condition at exterior openings, and finish appearance.
+
+### An accepted mock-up may remain as part of the completed work where the Architect designates it in writing.
+
+# The Opening Schedule {toc}
+
+## What the Schedule Establishes {toc}
+
+### The opening schedule is the instrument that assigns each opening its leaf material, size, rating, and hardware set. Selections that vary opening by opening belong there, while the datasheet in this standard sets the project-wide policies those per-opening selections draw from. {note}
+
+### The opening schedule shall assign a mark number to every swinging opening in the work and shall list, for each mark, the leaf width, leaf height, leaf material, hand and swing, frame type, wall type, fire protection rating, glazing, and hardware set reference.
+
+### Leaf width, leaf height, hand, and swing shall be [[drawing: as indicated on the opening schedule]].
+
+### Frame throat opening shall match the wall construction the frame meets, [[drawing: as indicated on the partition schedule]].
+
+### No opening shall be left on the schedule without a hardware set reference, and no opening shall be described by a phrase such as matching an existing condition in place of a set reference.
+
+### An opening carried on the schedule without a set reference produces a field decision made by whoever is standing there, and that decision can defeat the fire protection rating or the accessible-route obligations without anyone noticing until inspection. {note}
+
+## Leaf Thickness {toc}
+
+### Door leaf thickness shall be as indicated in the datasheet unless a listed fire door assembly or an oversized leaf requires a greater thickness.
+
+```datasheet
+label: Door Leaf Thickness
+type: range
+unit: in
+options:
+ min: 1.375
+ max: 2.25
+ setpoints: [1.375, 1.75, 2.25]
+default: 1.75
+```
+
+### Leaves 1-3/8 in. thick shall not be used at a fire-rated opening, at an opening carrying an exit device, or at an opening carrying a mortise lockset, because none of those preparations fits the reduced stile depth.
+
+### For leaves wider than 4 ft or taller than 8 ft, the Contractor shall obtain written confirmation from the leaf manufacturer and the frame fabricator that the selected thickness, core, and hinge arrangement carry the leaf at the scheduled size.
+
+## Hardware Set Assignment {toc}
+
+### Every opening shall carry exactly one hardware set number, and all openings carrying the same set number shall receive identical hardware.
+
+```datasheet
+label: Hardware Set Designation
+type: text
+drawing_ref: "the opening schedule"
+default: deferred
+```
+
+### The hardware schedule shall state, for each item in each set, the ANSI/BHMA standard, the function designation, the grade, the finish code, the size, and the fastening method.
+
+# Hollow Metal Doors {toc}
+
+## Performance Level and Model {toc}
+
+### ANSI/SDI A250.8 sorts steel doors on two independent axes. The performance level, verified by the physical endurance testing of ANSI/SDI A250.4, fixes face-sheet thickness and construction robustness. The model describes how the faces are joined and finished at the edges and is an appearance and fabrication choice. {note}
+
+### The performance level of each hollow metal leaf shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Door Performance Level
+type: select
+drawing_ref: "the opening schedule"
+options:
+ - "Level 1 — Standard Duty"
+ - "Level 2 — Heavy Duty"
+ - "Level 3 — Extra Heavy Duty"
+ - "Level 4 — Maximum Duty"
+default: deferred
+```
+
+### The model of each hollow metal leaf shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Door Model
+type: select
+drawing_ref: "the opening schedule"
+options:
+ - "Model 1 — Full flush"
+ - "Model 2 — Seamless"
+ - "Model 3 — Stile and rail"
+default: deferred
+```
+
+### Model 3 stile-and-rail construction is offered at Level 3 under ANSI/SDI A250.8, and the Contractor shall confirm the level and model combination against the fabricator's current listing before the leaf is released for fabrication.
+
+### Minimum face-sheet thickness shall be the value stated in ANSI/SDI A250.8 for the selected performance level, as follows.
+
+| Performance Level | Minimum Face Sheet Thickness | Nominal Gauge |
+|---|---|---|
+| Level 1 — Standard Duty | 0.032 in. | 20 |
+| Level 2 — Heavy Duty | 0.042 in. | 18 |
+| Level 3 — Extra Heavy Duty | 0.053 in. | 16 |
+| Level 4 — Maximum Duty | 0.067 in. | 14 |
+
+### Face-sheet thickness follows from the performance level and is not a separate selection. Specifying a level and a thickness independently is how a schedule ends up contradicting itself, so the datasheet carries the level and this table carries the consequence. {note}
+
+## Hollow Metal Face Sheet Material {toc}
+
+### Face sheets and frame members for openings that are not exposed to weather, washdown, or an aggressive interior atmosphere shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Face Sheet Material — Interior Openings
+type: select
+options:
+ - "Cold-rolled steel sheet, ASTM A1008"
+ - "Hot-rolled pickled and oiled steel sheet, ASTM A1011"
+ - "Galvannealed steel sheet, ASTM A653 A40 coating"
+ - "Galvannealed steel sheet, ASTM A653 A60 coating"
+ - "Hot-dip galvanized steel sheet, ASTM A653 G60 coating"
+ - "Stainless steel sheet, ASTM A240 Type 304"
+ - "Stainless steel sheet, ASTM A240 Type 316"
+default: "Cold-rolled steel sheet, ASTM A1008"
+```
+
+### Face sheets and frame members for openings exposed to weather, to wind-driven rain, to washdown, to sustained high humidity, or to an aggressive interior atmosphere shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Face Sheet Material — Exterior and Wet Openings
+type: select
+options:
+ - "Galvannealed steel sheet, ASTM A653 A60 coating"
+ - "Hot-dip galvanized steel sheet, ASTM A653 G60 coating"
+ - "Hot-dip galvanized steel sheet, ASTM A653 G90 coating"
+ - "Stainless steel sheet, ASTM A240 Type 304"
+ - "Stainless steel sheet, ASTM A240 Type 316"
+ - "Cold-rolled steel sheet, ASTM A1008, with a field-applied protective coating system"
+default: "Galvannealed steel sheet, ASTM A653 A60 coating"
+```
+
+### A zinc coating carries a mass of zinc per unit area, and the designation states it: an A60 galvannealed coating and a G60 galvanized coating carry the same 0.60 oz/ft² total on both faces, while G90 carries half again as much. Galvannealed surfaces are iron-zinc alloy and take paint directly. Hot-dip galvanized surfaces are free zinc and need a conversion coat or an etch primer before paint, which is where field-painted galvanized openings most often fail. {note}
+
+### Frames shall be fabricated from the same material class as the leaves they receive, unless the datasheet or the opening schedule establishes otherwise for a specific opening.
+
+### The exposed faces of stainless steel doors and frames shall carry a No. 4 satin directional finish with the polishing direction running vertically on jambs and faces and horizontally on heads.
+
+## Hollow Metal Core Construction {toc}
+
+### The core carries the sandwich. It sets the leaf's stiffness and dent resistance, its thermal resistance at an exterior opening, its sound transmission class, and its ability to hold a screw where hardware lands away from a reinforcement. {note}
+
+### The core of hollow metal leaves at interior openings that carry no fire protection rating shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Core — Interior Non-Rated Openings
+type: select
+options:
+ - "Kraft paper honeycomb, resin impregnated"
+ - "Expanded polystyrene board"
+ - "Polyurethane foam, poured in place"
+ - "Polyisocyanurate board"
+ - "Vertical steel stiffeners with fiberglass batt infill"
+ - "Vertical steel stiffeners with mineral wool infill"
+ - "Mineral board"
+ - "Lead sheet lining over a honeycomb core"
+default: "Kraft paper honeycomb, resin impregnated"
+```
+
+### The core of hollow metal leaves at exterior openings shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Core — Exterior Openings
+type: select
+options:
+ - "Expanded polystyrene board"
+ - "Polyurethane foam, poured in place"
+ - "Polyisocyanurate board"
+ - "Vertical steel stiffeners with fiberglass batt infill"
+ - "Vertical steel stiffeners with mineral wool infill"
+ - "Kraft paper honeycomb, resin impregnated"
+default: "Expanded polystyrene board"
+```
+
+### Where a fire protection rating applies to the opening, the core shall be the core named in the fire door assembly listing, and the datasheet selections above shall not override it.
+
+### Where the opening schedule assigns a sound transmission class rating, the core and the perimeter seal assembly shall together be part of a configuration tested to ASTM E90 and rated to ASTM E413 at or above the scheduled value.
+
+### Foamed-in-place polyurethane bonds continuously to both face sheets and raises thermal resistance and stiffness, at the cost of a core that cannot be machined in the field. Vertical steel stiffeners resist denting and hold hardware anywhere along the leaf, and the insulation between them is what carries the thermal and acoustic performance. {note}
+
+## Hollow Metal Edge and Closure Construction {toc}
+
+### Vertical edges of hollow metal leaves shall be continuously welded and ground smooth, or shall be interlocked and mechanically joined, and the edge treatment furnished shall be the treatment covered by the fabricator's listing where the opening is rated.
+
+### The top edge of every exterior hollow metal leaf shall be closed flush with a steel closure channel welded to the faces so that water cannot enter the leaf.
+
+### The top and bottom edges of interior hollow metal leaves shall be closed with a steel channel welded or mechanically attached to the faces.
+
+### Hardware reinforcements shall be welded into the leaf and the frame in accordance with ANSI/SDI A250.6, and shall be of a steel thickness not less than the thickness required by that standard for the item they receive.
+
+### Reinforcement is a factory operation and cannot be added later. A frame that reaches the site without a closer reinforcement will either receive a through-bolted closer or a sex-bolted plate, both of which are visible, and neither of which is what was specified. {note}
+
+# Hollow Metal Frames {toc}
+
+## Frame Steel Thickness {toc}
+
+### The minimum steel thickness of frame members shall be as indicated in the datasheet, and shall in no case be less than the minimum stated in ANSI/SDI A250.8 for the performance level and opening size served.
+
+```datasheet
+label: Minimum Frame Steel Thickness
+type: select
+options:
+ - "18 gauge, 0.042 in. minimum"
+ - "16 gauge, 0.053 in. minimum"
+ - "14 gauge, 0.067 in. minimum"
+ - "12 gauge, 0.093 in. minimum"
+default: "16 gauge, 0.053 in. minimum"
+```
+
+### Frames receiving continuous hinges, heavy-weight butt hinges, exit device strikes, or electric strikes shall be reinforced at those preparations with steel of a thickness not less than that required by ANSI/SDI A250.6, regardless of the frame body thickness selected.
+
+## Frame Profile {toc}
+
+### The frame face dimension shall be as indicated in the datasheet.
+
+```datasheet
+label: Frame Face Dimension
+type: range
+unit: in
+options:
+ min: 1.75
+ max: 4
+ setpoints: [1.75, 2, 3, 4]
+default: 2
+```
+
+### The frame throat opening shall equal the finished thickness of the wall the frame meets, including any tile, plaster, or panel applied over the substrate, and the Contractor shall verify the finished thickness before frames are released for fabrication.
+
+### Throat opening is the single most common source of frames that arrive on site and do not fit. It is a wall dimension, not a frame catalog choice, and it changes whenever a finish is added to a partition after the frames are ordered. {note}
+
+### Frame rabbet depth shall suit the leaf thickness selected, and the stop height shall be not less than 5/8 in.
+
+### Double-rabbet profiles shall be furnished where leaves swing in both directions at one frame, and single-rabbet profiles shall be furnished elsewhere unless the opening schedule establishes otherwise.
+
+## Frame Construction Method {toc}
+
+### The construction method of each frame shall be as indicated in the datasheet.
+
+```datasheet
+label: Frame Construction Method
+type: select
+drawing_ref: "the opening schedule"
+options:
+ - "Fully welded frame, corners welded and ground smooth"
+ - "Face-welded frame with concealed corner joints"
+ - "Knocked-down frame, field assembled"
+ - "Slip-on drywall frame"
+default: deferred
+```
+
+### A welded frame arrives as a rigid rectangle whose dimensions were set in the shop, which is why it survives being built into masonry. A knocked-down frame is assembled around a completed stud opening and depends on the framing for its squareness. A slip-on drywall frame wraps a finished board edge and is set last, which makes it the fastest to install and the least resistant to racking. {note}
+
+### Frames at fire-rated openings shall be of a construction method covered by the frame fabricator's listing for the required rating period.
+
+### Frames in masonry and concrete walls shall be delivered as a welded unit unless the opening schedule and the frame fabricator's written instructions together establish a knocked-down frame suitable for that wall type.
+
+### Frames wider than 4 ft in a single opening, and all frames at pairs, shall be delivered welded unless the frame fabricator confirms in writing that the knocked-down profile carries the opening width without deflection at the head.
+
+## Frame Anchorage {toc}
+
+### The anchor type at each frame shall be as indicated in the datasheet and shall suit the wall construction the frame meets.
+
+```datasheet
+label: Frame Anchor Type
+type: select
+drawing_ref: "the opening schedule"
+options:
+ - "Masonry T-strap anchor"
+ - "Masonry wire strap anchor"
+ - "Post-installed expansion anchor for existing masonry"
+ - "Steel stud anchor, welded"
+ - "Steel stud anchor, snap-in"
+ - "Wood stud anchor"
+ - "Compression anchor for knocked-down frames"
+ - "Poured-in-place concrete anchor"
+ - "Welded connection to structural steel"
+default: deferred
+```
+
+### Anchors shall be factory welded or factory attached to the frame jambs, and anchors shall not be field fabricated.
+
+### Anchor quantity and spacing shall comply with ANSI/SDI A250.11 for the frame height and wall type, and shall in no case place fewer than three anchors on each jamb.
+
+### The topmost and bottommost anchors on each jamb shall be located within 6 in. of the frame head and the frame base respectively.
+
+### At fire-rated frames, anchor type, quantity, and spacing shall be those stated in the frame listing where the listing establishes values more restrictive than ANSI/SDI A250.11.
+
+### Every frame in a stud partition shall receive a floor anchor at each jamb fastened to the structural floor.
+
+### The Contractor shall install a full-height stud or a header assembly at each jamb of a frame set in a stud partition, sized to restrain the frame against the operating loads of the leaf and its closer, before the frame is set.
+
+### Compression anchors hold a knocked-down frame by friction against the board faces. They are quick, and they are also the reason a heavily used drywall-frame opening works loose over a few years, because nothing in that connection resists the cyclic load the closer applies every time the leaf shuts. {note}
+
+## Frame Grout Fill {toc}
+
+### The scope of grout filling shall be as indicated in the datasheet.
+
+```datasheet
+label: Frame Grout Fill Scope
+type: select
+options:
+ - "All frames set in masonry or concrete"
+ - "Exterior and fire-rated frames set in masonry or concrete"
+ - "No frames grout filled"
+default: "All frames set in masonry or concrete"
+```
+
+### Grout used to fill frames shall be a low-water-content mix that does not corrode the frame interior. Plaster-type grout, low-slump masonry grout conforming to ASTM C476, and low-slump Portland cement mortar are each acceptable where the mix meets that requirement.
+
+### Grout shall not be placed in a frame in lifts exceeding 24 in., and the frame shall be checked for plumb and square after each lift.
+
+### The Contractor shall protect hardware preparations, strike boxes, silencer holes, and electrical raceway stubs from grout intrusion, and shall remove any grout that reaches them before it sets.
+
+### The Contractor shall not hang a leaf on a grouted frame until the grout has cured sufficiently to develop the anchor restraint.
+
+### Grout raises the frame's mass and its resistance to racking, and at an exterior or rated opening it also closes the cavity that would otherwise let heat and sound pass around the frame. High-water grout mixes leave standing moisture inside a closed steel section, which is the mechanism behind frames that rust from the inside out. {note}
+
+## Frame Hardware Preparation {toc}
+
+### Frames shall be factory prepared and reinforced for every hardware item assigned to the opening, in accordance with ANSI/BHMA A156.115.
+
+### Factory preparation shall include hinge mortises and reinforcements, strike preparation and strike box, closer reinforcement, stop and holder reinforcement, silencer holes, and raceway and junction box provisions for electrified items.
+
+### Field cutting of hinge or strike preparations is not permitted, except for a dimensional adjustment of 1/16 in. or less documented in writing and accepted by the frame fabricator.
+
+### Raceway for electrified hardware shall be factory installed within the frame and shall extend not less than 6 in. beyond the frame into the wall cavity above the head.
+
+### Raceway within the frame shall be not less than 1/2 in. trade size, and shall be increased where the conductor count and conductor size for the opening require it as confirmed by the access control installer.
+
+### The junction box location for each electrified opening shall be established before the frame is fabricated, because reaching a frame raceway after the wall is closed means opening the wall. {note}
+
+## Hollow Metal Finish {toc}
+
+### The factory finish on hollow metal doors and frames shall be as indicated in the datasheet.
+
+```datasheet
+label: Hollow Metal Factory Finish
+type: select
+options:
+ - "Factory prime coat only"
+ - "Factory prime coat with a factory-applied finish coat"
+ - "Factory-applied powder coat over a prime coat"
+ - "Mill-galvanized surface, field primed and painted"
+ - "Stainless steel, No. 4 satin directional finish"
+default: "Factory prime coat only"
+```
+
+### Surfaces receiving a factory prime coat shall be cleaned, treated with a phosphate or equivalent conversion coating, and primed with a rust-inhibiting primer meeting the acceptance criteria of ANSI/SDI A250.10.
+
+### The factory prime coat is a bonding and pretreatment layer, not a finish. It carries no meaningful corrosion protection once the leaf is standing in weather, which is why an exterior opening left in primer through a winter arrives at painting with rust bloom to remove. {note}
+
+### The Contractor shall apply the field finish to exterior doors and frames before they are exposed to weather, and shall apply the field finish to interior doors before hardware is mounted wherever the sequence allows.
+
+### Damage to a factory prime or factory finish coat shall be repaired with the coating manufacturer's touch-up material before the field finish is applied.

+### ANSI/WDMA I.S. 1A grades performance by duty level, which sets the minimum cycle, hinge-load, and screw-holding performance the door construction must deliver. Duty level and appearance are separate decisions, and a door can be built to the highest duty level with the plainest face. {note}
+
+### The performance duty level of wood doors shall be as indicated in the datasheet.
+
+```datasheet
+label: Wood Door Performance Duty Level
+type: select
+options:
+ - "Standard Duty"
+ - "Heavy Duty"
+ - "Extra Heavy Duty"
+default: "Heavy Duty"
+```
+
+### Wood doors at openings that carry a fire protection rating shall be of a duty level and construction covered by the manufacturer's listing for the required rating period.
+
+### Where an opening is subject to frequent public use, to trolley or cart contact, or to a closer set for a high closing force, the Contractor shall confirm with the door manufacturer in writing that the selected duty level carries that service.
+
+## Wood Door Appearance Grade {toc}
+
+### The appearance grade of wood doors shall be as indicated in the datasheet.
+
+```datasheet
+label: Wood Door Appearance Grade
+type: select
+options:
+ - "Economy"
+ - "Custom"
+ - "Premium"
+default: "Custom"
+```
+
+### The appearance grade governs the permitted natural characteristics of the face veneer, the number and size of permitted patches and repairs, and the matching tolerances within and between leaves, in accordance with the Architectural Woodwork Standards.
+
+### Where the datasheet selection and the Architectural Woodwork Standards describe the same characteristic differently, the more restrictive description shall govern.
+
+## Wood Door Core Construction {toc}

+ - "Institutional light-density hollow core"
+ - "Lead sheet lining over a particleboard core"
+default: "Particleboard, ANSI A208.1 LD-1"
+```
+
+### Wood doors at openings that carry a fire protection rating shall be built on the core named in the manufacturer's listing for that rating period, and the datasheet selection above shall not override it.
+
+### The core is the substrate every hardware screw lands in and the mass that sets the door's sound transmission class. Structural composite lumber and stave lumber hold a screw where a bonded particleboard core will not, which matters where a mortise lock, a continuous hinge, or an exit device chassis is fastened into the stile. {note}
+
+### Where the opening schedule assigns a sound transmission class rating, the core, the edge construction, and the perimeter seal assembly shall together be part of a configuration tested to ASTM E90 and rated to ASTM E413 at or above the scheduled value.

+options:
+ - "Plain sliced"
+ - "Quarter sliced"
+ - "Rift cut"
+ - "Rotary cut"
+ - "Half-round sliced"
+default: "Plain sliced"
+```
+
+### The cut determines the figure. Plain slicing produces the cathedral figure most people picture when they think of a wood door, quarter slicing produces a straight stripe, and rift cutting suppresses the medullary ray flake that oak shows when quartered. Rotary cutting peels a continuous sheet and yields a wild, wide figure that is difficult to match between leaves. {note}
+
+### Faces shall be not less than three-ply construction with a crossband between the face veneer and the core, except where the face material selected is not a veneer.
+
+## Wood Door Veneer Matching {toc}
+
+### Veneer matching within each leaf shall be as indicated in the datasheet.

+```datasheet
+label: Veneer Matching Within the Leaf
+type: select
+options:
+ - "Book match"
+ - "Slip match"
+ - "Random match"

+type: select
+options:
+ - "Pair and set match"
+ - "Continuous match across the set"
+ - "No matching required between leaves"
+default: "Pair and set match"
+```
+
+### Book matching turns alternate leaves of veneer over, so adjacent sheets mirror one another and the tight and loose faces alternate. Where a stain is applied, the alternating faces take it differently and produce the light-and-dark barber-pole effect, which is why slip matching is used where an even stain response matters more than symmetry. {note}
+
+### Where the Owner will require matching doors in a future phase, the Contractor shall record the flitch identification in the closeout documentation.
+
+## Wood Door Edge Construction {toc}
+
+### The edge band on wood doors shall be as indicated in the datasheet.

+default: "Hardwood edge, species compatible with the face veneer"
+```
+
+### Vertical edges shall be banded not less than 1/8 in. thick after machining, bonded to the core, and applied before the face veneer so that no glue line shows on the face.
+
+### The edge on a leaf receiving a mortise lockset, a mortise exit device, or a continuous hinge shall provide solid material through the full depth of the preparation.
+
+### At fire-rated wood doors, the edge material, its thickness, and its attachment shall be those stated in the manufacturer's listing.
+
+### Where the opening schedule assigns a positive pressure rating, the edge treatment and any intumescent edge material shall be that stated in the listing for the assembly.
+
+## Wood Door Finishing {toc}
+
+### The finishing of wood doors shall be as indicated in the datasheet.
+
+```datasheet

+ - "Factory-applied catalyzed transparent finish"
+ - "Factory-applied catalyzed opaque finish"
+ - "Factory-applied UV-cured finish"
+```
+
+### Doors delivered unfinished shall be sealed on all six surfaces, including the top and bottom edges and every cutout, within the interval stated in the manufacturer's written instructions after the door is hung.
+
+### The top and bottom edges of every wood door shall be sealed before the door is installed, whether the door is factory finished or field finished.
+
+### Factory finishing is applied in a controlled booth and cured before the door reaches a jobsite, which produces a harder film and a more uniform sheen than a field finish can. It also fixes the color before the adjacent millwork is finished, so a factory-finished door and a field-finished frame or casing have to be reconciled by sample rather than in place. {note}
+
+### Where the Contractor field-cuts or field-machines a factory-finished door within the limits the manufacturer allows, the cut surfaces shall be sealed with the manufacturer's touch-up material before the door is hung.
+
+# Fire-Rated and Smoke-Rated Openings {toc}
+
+## The Listed Assembly {toc}
+
+### A fire door assembly is not a rated leaf hung in a rated frame. It is a specific combination of leaf, frame, hinges, latching hardware, closing device, gasketing, glazing, and glazing bead that was tested together and carries a label as that combination. Substituting any component, even one that looks identical, changes the tested configuration. {note}
+
+### Every component of a fire door assembly shall be part of an assembly listed by a nationally recognized testing laboratory in the configuration to be installed.
+
+### Fire door assemblies shall be installed and maintained in accordance with NFPA 80.
+
+### The Contractor shall not substitute any component within a listed fire door assembly without written confirmation from the listing laboratory that the substitution falls within the existing listing or that a separate listing covers the modified configuration.
+
+### The Contractor shall not field modify a listed assembly, including cutting a vision light opening, adding a hinge, drilling a through-bolt, or applying a plate larger than the listing permits, without the written confirmation required above.
+
+### Any change to the hardware on a rated opening after the hardware submittal is accepted shall be reviewed against the listing before the change is procured.
+
+## Fire Protection Rating {toc}
+
+### The fire protection rating of each opening shall be as indicated in the datasheet.
+
+```datasheet
+label: Fire Protection Rating of the Opening
+type: range
+unit: min
+drawing_ref: "the opening schedule"
+options:
+ min: 0
+ max: 180
+ setpoints: [0, 20, 45, 60, 90, 180]
+default: deferred
+```
+
+### A rating of 0 minutes designates an opening that the building code does not require to be an opening protective. {note}
+
+### The Architect shall establish the required rating period for each opening from the fire-resistance-rated construction shown on the building code compliance drawings, and shall record it on the opening schedule.
+
+### The building code sets the rating an opening protective must carry from the rating of the assembly it penetrates, and the relationship is not one to one. An opening in a 2-hour fire barrier is protected by a 90-minute assembly, an opening in a 1-hour fire barrier by a 60-minute assembly, and a corridor opening in a fire partition by a 20-minute assembly, with the governing values stated in the opening protective tables of IBC Chapter 7. {note}
+
+### Where the required rating period changes after frames are fabricated, the Contractor shall notify the Architect in writing before installing the affected frame, because a non-rated frame cannot be upgraded in place.
+
+## Temperature Rise Doors {toc}
+
+### Where the building code requires a limited transmitted temperature rise at an opening, the leaf shall be listed to a maximum transmitted temperature rise of 450°F above ambient at 30 minutes of standard fire test exposure.
+
+### The Contractor shall submit the leaf manufacturer's listing documentation confirming the transmitted temperature rise classification for every opening subject to that requirement.
+
+### The building code applies the transmitted temperature rise limit to fire door assemblies in interior exit stairways, interior exit ramps, and exit passageways, and in the model code it is waived where the building is sprinklered throughout in accordance with the referenced automatic sprinkler provisions. The controlling provision is Section 716.2.2.3 in the 2021 edition of the IBC, and the Architect confirms the section as adopted by the authority having jurisdiction. {note}
+
+### A temperature rise limit is not about flame passage. It restricts how hot the unexposed face of the leaf becomes, so that occupants descending a stairway past a burning floor are not driven back by radiant heat from a door that is otherwise holding. {note}
+
+## Positive Pressure Fire Testing {toc}
+
+### Fire door assemblies shall be listed on the basis of testing to UL 10C or to NFPA 252 conducted under the positive pressure condition.
+
+### The Contractor shall not furnish an assembly listed only to the neutral or negative pressure condition of UL 10B in place of an assembly required to carry a positive pressure listing.
+
+### The label shall identify the test standard under which the assembly was listed.
+
+### In a positive pressure test the pressure neutral plane is set low in the furnace, so hot gases push outward across most of the door's height for the whole test rather than being drawn inward. Assemblies that passed comfortably under the older neutral-pressure protocol frequently need intumescent edge seals to pass under this one, which is why edge seal material appears in listings where it once did not. {note}
+
+## Labels and Their Protection {toc}
+
+### Every fire-rated leaf and every fire-rated frame shall bear a permanent label applied at the factory by the listing laboratory or under its supervision.
+
+### Labels shall not be removed, painted over, covered, or defaced at any time during construction.
+
+### The Contractor shall protect labels during field painting and shall clean any label that receives overspray before the surface cures.
+
+### Where a label is missing, illegible, or painted over at turnover, the Contractor shall obtain a field label from the listing laboratory or replace the component, at no cost to the Owner.
+
+### Labels are ordinarily applied to the hinge edge of the leaf and to the hinge jamb rabbet of the frame, which places both of them in the path of a paint roller working the jamb. {note}
+
+## Fire-Rated Pairs {toc}
+
+### Pairs of fire-rated leaves shall be furnished with a closing sequence device listed as a component of the fire door assembly, so that the inactive leaf closes and latches before the active leaf closes over it.
+
+### Both leaves of a fire-rated pair shall be positively latched when closed.
+
+### Where the listing for a rated pair requires an astragal, the astragal profile, material, and attachment shall be those stated in the listing.
+
+### The inactive leaf latching method at rated pairs shall be as indicated in the datasheet.
+
+```datasheet
+label: Inactive Leaf Latching at Rated Pairs
+type: select
+options:
+ - "Automatic flush bolts released by the active leaf"
+ - "Manual flush bolts at the head and the floor"
+ - "Exit device on both leaves"
+ - "Removable mullion with a rim device on each leaf"
+default: "Automatic flush bolts released by the active leaf"
+```
+
+### A manual flush bolt only holds the inactive leaf if someone re-engaged it after the last time the pair was opened wide. Automatic flush bolts extend when the active leaf closes, and a removable mullion converts the pair into two independently latching openings, at the cost of an obstruction in the clear width whenever the mullion is in place. {note}
+
+## Smoke and Draft Control Assemblies {toc}
+
+### Whether a smoke and draft control assembly is required at each opening shall be as indicated in the datasheet.
+
+```datasheet
+label: Smoke and Draft Control Assembly
+type: radio
+drawing_ref: "the opening schedule"
+options:
+ - "Smoke and draft control assembly required at this opening"
+ - "Smoke and draft control assembly not required at this opening"
+default: deferred
+```
+
+### Smoke door assemblies shall comply with NFPA 105 and shall be listed on the basis of air leakage testing to UL 1784.
+
+### Smoke and draft control assemblies shall be furnished with gasketing continuous around the head and both jambs, a self-closing device, and positive latching on every leaf.
+
+### Where one opening is required to be both a fire door assembly and a smoke and draft control assembly, the assembly shall carry both listings and the Contractor shall submit documentation of each.
+
+### The smoke test is not a fire test. It measures air leakage through the assembly at ambient and elevated temperature, which is why an assembly can hold a fire protection rating for 90 minutes and still fail as a smoke barrier if the perimeter gasketing is absent. {note}
+
+## Gasketing at Rated Openings {toc}
+
+### Gasketing and intumescent edge seals at fire-rated openings shall be the products named in the listing and shall be installed in the positions the listing documentation shows.
+
+### The Contractor shall not add gasketing, seal material, or acoustic treatment to a rated opening beyond what the listing names without the written confirmation of the listing laboratory.
+
+### Intumescent seals shall be delivered and installed uncompressed, unpainted, and undamaged.
+
+### Intumescent material expands many times its installed volume when it reaches its activation temperature, closing the clearance between leaf and frame. Paint over it, compress it in storage, or trim it to fit a preparation and it will not reach the volume the test assumed. {note}
+
+# Hardware Sets {toc}
+
+## Hardware shall be organized into numbered sets, and the hardware schedule shall list every item in each set with its manufacturer designation, ANSI/BHMA standard, function, grade, size, finish code, and fastening method.
+
+## Each hardware set shall be verified against the leaf material, leaf thickness, leaf weight, hand, swing, fire protection rating, and egress function of every opening assigned to it before the set is released for procurement.
+
+## Where an item within a set is unavailable in the finish selected for the project, the supplier shall submit the substitution for review rather than shipping the nearest available finish.
+
+## Hardware furnished under this standard shall be from as few manufacturers as the set requirements allow, so that keying, finish, and template dimensions remain consistent across the work.
+
+## Fasteners furnished with hardware shall be of the same material class as the item they fasten, and machine screws into steel reinforcement shall be used in place of wood screws wherever a reinforcement is present.
+
+# Hinges and Pivots {toc}
+
+## Hinges shall conform to ANSI/BHMA A156.1, continuous hinges shall conform to ANSI/BHMA A156.26, and self-closing hinges and pivots shall conform to ANSI/BHMA A156.17.

+ - "Spring hinge, self-closing"
+default: "Full mortise butt hinge"
+```
+
+## A butt hinge concentrates the leaf's weight at two or three points on the stile. A continuous hinge spreads it along the full height, which is why continuous hinges appear at high-cycle openings, at leaves that have already torn out a butt hinge once, and at exterior leaves where the added stiffness also resists prying. Pivots carry the load into the floor and head instead of the jamb, which is what makes them the choice for very heavy or very wide leaves. {note}

+
+| Leaf Height | Minimum Hinge Quantity |
+|---|---|
+| Up to 5 ft 0 in. | 2 |

+| 1-3/4 in. thick, over 4 ft 0 in. wide | 6 in. |
+| Over 1-3/4 in. thick, any width | 5 in. minimum, confirmed against the leaf weight |
+
+## Hinge width shall be sufficient to clear the trim, the frame face, and any wall condition the leaf must swing past.
+
+## Heavy-weight hinges shall be furnished where the leaf exceeds 200 lb, where the opening is subject to high-frequency use, or where the leaf carries an exit device or a closer set above the manufacturer's standard spring power.
+
+## Hinges at outswinging exterior openings and at openings serving secured spaces shall be furnished with non-removable pins, security studs, or a continuous hinge that presents no removable pin.

+
+# Locksets and Latches {toc}
+
+## Bored locksets shall conform to ANSI/BHMA A156.2, mortise locksets shall conform to ANSI/BHMA A156.13, and auxiliary locks shall conform to ANSI/BHMA A156.36.
+
+## The lockset chassis type used as the project standard shall be as indicated in the datasheet.

+default: "Bored cylindrical lockset"
+```
+
+## A mortise case sits inside a pocket machined into the stile and carries a deadbolt, an auxiliary latch, and the lever mechanism in one housing, which is what lets it offer functions a bored lock cannot. A bored lock passes through two holes and is faster to install, easier to replace, and less demanding of the leaf's edge construction. Both are made to Grade 1 and both are used across commercial work. {note}

+## The BHMA grade is a test result, not a marketing tier. A Grade 1 bored lock completes one million cycles under ANSI/BHMA A156.2 and withstands the corresponding strength and security tests, Grade 2 completes eight hundred thousand, and Grade 3 completes two hundred thousand. Where an opening is cycled continuously, the difference between the grades is measured in years of service before the first rebuild. {note}

+## A door in a means of egress shall be openable from the egress side in one operation, without a key, without a tool, and without special knowledge or effort, except where the building code expressly permits a controlled egress or delayed egress arrangement and that arrangement is installed in full compliance with the permitting provision.
+
+## Locking a means of egress door against the direction of travel is one of the few things in a specification that can kill someone. Every controlled-egress and delayed-egress arrangement the code allows carries a list of conditions attached to it, and all of them have to be satisfied together, not selectively. {note}

+```
+
+### Every keyed device on the project shall accept the cylinder format selected, so that a single core inventory serves the whole building.
+
+### An interchangeable core comes out with a control key and goes back in without disassembling the lock. That is what makes rekeying a whole building a walk-through rather than a shutdown, and it is also why the control key becomes the most security-sensitive key on the project. {note}

+```
+
+### Where the Owner operates an existing key system at other facilities, the Owner shall confirm in writing whether this project joins that system before cylinders are ordered.
+
+### An open keyway means blanks are available to any locksmith, so a key can be copied by anyone holding it. A patented keyway restricts blanks to authorized channels for the life of the patent, and a high-security cylinder adds physical resistance to picking and drilling on top of that restriction. Where a building's key control depends on keys not being duplicated, the keyway is the mechanism that enforces it. {note}

+## Fire exit hardware shall not be furnished with a dogging feature that holds the latch retracted, because a fire door assembly has to latch every time it closes.
+
+## Vertical rod devices that latch into the floor place a strike in the path of a mop, a cart wheel, and every shoe that crosses the opening. Where the listing and the opening permit it, a device that latches only at the head removes the floor strike and the bottom rod adjustment along with it, at the cost of relying on a single latching point. {note}

Head-end controllers, credentials, software, and the programming that decides who may pass are governed by [[sync/access-control-systems]], and the relay that drops a hold-open device on alarm is governed by [[sync/fire-alarm-systems]]. {note}
+
+### The Contractor shall issue a point-to-point wiring diagram for every electrified opening, showing each device, its voltage and current draw, its conductor count and size, the raceway path, and the terminating equipment.

+```
+
+### A door in a means of egress that is electrically locked shall release on loss of power, unless the installation satisfies in full a building code provision that expressly permits the arrangement without that release.
+
+### Every electromagnetic lock shall release on activation of the fire alarm system, on activation of the automatic sprinkler system, on loss of power, and on operation of the request-to-exit device that serves it.
+
+### The fail mode carries opposite consequences at the two ends. A fail-secure opening that loses power holds people on the wrong side of it. A fail-safe opening that loses power opens a secured space to anyone in the building. Which risk a project accepts is a decision for the Owner with the Architect, and it belongs on the opening schedule so it is recorded per opening rather than assumed. {note}

+### Conductors crossing from the frame into the leaf shall be carried in a device made for that purpose and shall not be looped unprotected across the hinge line.
+
+### The transfer device shall be included in the hardware set for every opening carrying a leaf-mounted electrified item.
+
+### An unprotected conductor at the hinge line flexes through its full bend radius every time the door swings. At a busy opening that is hundreds of cycles a day, and the failure it produces is intermittent long before it is total, which is why it usually gets diagnosed as a controller fault first. {note}

+
+### Each power supply shall be labeled with a permanent identification listing the openings it serves.
+
+### Conductor size for each electrified device circuit shall be selected so that the voltage at the device under its rated load remains within the device manufacturer's stated operating range.
+
+### An electromagnetic lock that receives less than its rated voltage still energizes and still appears to be locked. It simply does not develop its rated holding force, and the deficiency is invisible until someone pulls on the door hard enough to find it. {note}
+
+## Fire Alarm Release of Hold-Open Devices {toc}
+
+### Every electromagnetic hold-open device on a fire door assembly or a smoke and draft control assembly shall be connected to the building fire alarm system so that alarm activation releases it.
+
+### The release circuit shall be arranged so that loss of power to the circuit also releases the device.
+
+### Activation of the fire alarm system shall release all hold-open devices within the affected zone simultaneously.
+
+### The Contractor shall coordinate the relay contacts, the release circuit conductors, and the device quantities with [[sync/fire-alarm-systems]].
+
+### Holding a fire door open with a wedge, a chair, a doorstop, or any device not connected to the fire alarm system is prohibited by NFPA 80, and the Contractor shall neither do so during construction nor leave such a condition at turnover.
+
+# Accessible Opening Requirements {toc}
+
+## Openings on an accessible route shall comply with the accessibility standard adopted by the authority having jurisdiction, and where the adopted standard and ICC A117.1 differ, the adopted standard shall govern.
+
+## The Architect shall identify the accessible route on the drawings, and the party preparing the hardware schedule shall confirm that every opening on that route complies with the requirements of this section.
+
+## Door hardware on an accessible route shall be mounted not less than 34 in. and not more than 48 in. above the finished floor.
+
+## Operable hardware on an accessible route shall be operable with one hand and shall not require tight grasping, tight pinching, or twisting of the wrist to operate.
+
+## The force required to operate operable hardware on an accessible route shall not exceed 5 lbf.
+
+## The force required to push or pull open an interior swinging egress door, other than a fire door assembly, shall not exceed 5 lbf applied at the latch edge, in accordance with IBC Section 1010.1.3.
+
+## Where a fire door assembly requires a closing force that cannot be reconciled with the opening force limit, the Contractor shall raise the conflict in writing with the Architect and the authority having jurisdiction rather than adjusting the closer below the force needed to latch the leaf.
+
+## Maneuvering clearances required by the adopted accessibility standard shall be maintained clear of floor stops, mat wells, casework, and any other obstruction, and the Architect shall confirm the clearances shown at each accessible opening before frames are set.
+
+## The opening force limit and the hardware operating force limit are separate obligations that apply at the same time. A lever that meets the operable-force limit on a door whose closer is set above the opening-force limit still leaves the opening non-compliant, and the reverse is equally true. {note}
+
+## Accessibility obligations are not selections. They apply wherever the route applies, and no datasheet entry in this standard relaxes them.
+
+# Delivery, Storage, and Handling {toc}
+
+## Doors and frames shall be delivered with their surfaces dry and free of condensation, and shall be inspected for damage before they are accepted at the site.
+
+## Hollow metal doors and frames shall be stored upright on dunnage above the ground, separated by spacers that permit air circulation, and protected from weather and from standing water.
+
+## Wrappings on hollow metal products shall be removed or slit on delivery so that moisture does not become trapped against the primed surface.
+
+## Wood doors shall be stored flat on a level surface, on not less than three supports, with the top door covered by an opaque protective sheet.
+
+## Wood doors shall not be delivered to the site until the building is enclosed, the wet work is complete and dry, and the permanent or an equivalent temporary conditioning system is operating.
+
+## Wood doors shall be stored and installed within the relative humidity range stated below, with the upper limit as indicated in the datasheet and the lower limit not less than 25 percent.
+
+```datasheet

+
+## A wood door is a laminated panel whose components change dimension with moisture content at different rates. Deliver it into a building that is still drying out and the faces and the core move against one another, which is what produces the warp and the telegraphed core lines that show up months after the door was hung. {note}
+
+## Hardware shall be delivered in the manufacturer's original packaging, marked with the opening mark and hardware set number, and stored in a locked, dry space until installation.
+
+## The Contractor shall maintain an inventory of delivered hardware by set number and shall report shortages before the corresponding openings are scheduled for installation.
+
+# Installation {toc}
+
+## Frame Installation {toc}
+
+### Frames shall be set plumb, level, square, and in true alignment, and shall be secured against displacement before adjacent wall construction is built against them.
+
+### Each jamb shall be plumb within 1/16 in. per foot of frame height, the frame shall be square within 1/16 in. measured on the diagonals, and the head shall be level within 1/16 in. across the opening.
+
+### The temporary shipping spreader on a welded frame shall be removed before the frame is set, and a calibrated setting spreader shall be used to hold the frame to its rabbet dimension during installation.
+
+### Frames set in masonry shall not be built into a wall until the wall can be brought up to the full frame height in a sequence that braces the frame without relying on temporary shoring alone.
+
+### Frames shall be checked for plumb and square after each grout lift and after the surrounding wall construction is complete, and shall be corrected before finishes are applied.
+
+### The frame base shall be set so that the frame bears on the structural floor, and the floor anchor shall be fastened before the frame is loaded.
+
+### Where a finished floor is applied after the frame is set, the frame base shall be located so that the finished floor brings the sill condition to the clearance the opening schedule requires.
+
+### Field welding of frames shall be performed only where the opening schedule or the frame fabricator's instructions permit it, and welds shall be ground smooth and touched up with a rust-inhibiting primer.
+
+## Leaf Hanging and Clearances {toc}
+
+### Leaves shall be hung after the frames are in final position, after the finished floor is installed, and after the building has reached the temperature and humidity conditions in which it will normally be occupied.
+
+### At openings that carry no fire protection rating, the clearance between the leaf and the frame at the head and each jamb shall be 1/8 in., and the clearance at the bottom shall be as required to clear the finished floor and any threshold or gasketing furnished.
+
+### At fire door assemblies, the clearance at the head, the jambs, and the meeting stiles of pairs shall not exceed 1/8 in. for wood leaves and 3/16 in. for steel leaves, unless the listing establishes a smaller maximum.
+
+### At fire door assemblies, the clearance between the bottom of the leaf and the finished floor shall not exceed 3/4 in., unless the listing establishes a smaller maximum.
+
+### Clearances exceeding the limits above at a rated opening shall be corrected before turnover, and the correction shall be made without field modification that falls outside the listing.
+
+### The clearance limits at a rated opening are not a workmanship preference. The gap around a fire door is the path hot gases take to reach the unexposed side, and the tested assembly was tested with that gap no larger than the listing allows. {note}
+
+### Where an automatic door bottom is furnished, the drop distance and the compressed seal height shall be set so that the seal makes continuous contact when the leaf is closed and clears the floor finish through the full swing.
+
+## Hardware Installation {toc}
+
+### Hardware shall be installed by workers experienced in commercial door hardware installation and familiar with the ANSI/BHMA standard applicable to each item furnished.
+
+### Hardware shall be installed at the locations and heights stated in DHI WDHS.3, except where the opening schedule, an accessibility requirement, or a fire door assembly listing establishes a different location.
+
+### Hardware preparations in the leaf and the frame shall be confirmed to align before any hole is drilled, because a misplaced hole in a rated assembly is a field modification that voids the listing.
+
+### Hinge leaves shall seat flush with the leaf and frame surfaces, with no rocking, no proud edge, and no shim stack between the leaf and the hinge.
+
+### Hinge screws shall be driven into the factory reinforcement, and a stripped screw shall be corrected by installing a machine screw into the reinforcement rather than by moving to a larger wood screw.
+
+### Closers shall be adjusted for backcheck, sweep speed, and latch speed after the building is enclosed and the conditioning system is operating, so that the adjustment reflects the pressure conditions the opening will see in service.
+
+### Exit devices shall be adjusted so that the touchbar moves freely, the latch retracts fully in one motion, the device relatches when the leaf closes, and any outside trim operates without binding.
+
+### Vertical rod devices shall be adjusted so that the top and bottom latches engage their strikes at the same point in the closing arc.
+
+### Every leaf furnished with a self-closing device shall close and latch from the fully open position without assistance, and the Contractor shall demonstrate this at each such opening.
+
+## Owner Instruction {toc}
+
+### At substantial completion the Contractor shall conduct a walkthrough of the installed hardware with the Owner's maintenance personnel.
+
+### The walkthrough shall cover closer adjustment, exit device adjustment, cylinder and core servicing, gasketing replacement, the key control record, and the Owner's annual fire door inspection obligation.
+
+### The Contractor shall provide the Owner with the list of components in each fire door assembly configuration and their listing documentation, so that future replacements can be matched to the listing.
+
+# Field Inspection of Fire Door Assemblies {toc}
