+title: Concrete Equipment Pads
+category: Sitework
+toc_depth: 3
+description: >
+ When to use: Cast-in-place concrete pads on grade or on slab that support mechanical and electrical equipment located outside the building envelope or in service yards. Typical applications include generator pads, pad-mounted transformer pads, switchgear and section-switch pads, condensing-unit and rooftop unit (RTU) pads where set at grade or on an exterior platform, pump and chiller pads, and similar isolated equipment foundations. Covers subgrade preparation references, formwork, mix selection, reinforcement, embedded anchor bolts, embedded grounding and conduit stubs, pour and consolidation, curing, finishing, tolerances, isolation joints to adjacent flatwork, and inspection.
+
+ Not intended for: Structural foundations integral to the building (footings, grade beams, mat foundations, pile caps) — see [[syncs/cast-in-place-concrete]]. Interior housekeeping pads inside mechanical and electrical rooms placed as a thin topping on the building slab — use [[syncs/cast-in-place-concrete]] for the topping pour. Precast concrete vault pads or precast transformer pads supplied with the equipment. Concrete-encased duct banks. Site flatwork (sidewalks, exterior slabs-on-grade) intended for pedestrian or vehicle traffic. Aggregate base course beneath the pad — see [[syncs/aggregate-base-course]]. Mass earthwork and subgrade preparation below the base course — see [[syncs/earthwork]].
+---
+
+# Scope
+
+This specification covers the materials, formwork, reinforcement, placement, embedded items, and curing of cast-in-place reinforced concrete equipment pads located on grade or on an exterior elevated platform. Equipment pads provide a level, dimensionally controlled, vibration-resistant bearing surface for mechanical and electrical equipment; they isolate the equipment from soil moisture and capillary rise, transfer equipment weight and seismic and wind loads to the subgrade, and provide cast-in-place anchorage for equipment hold-downs and grounding electrodes.
+
+A pad is small in volume relative to the equipment it carries, and the cost of correcting a defective pad is dominated by the cost of removing and reinstalling the equipment that sits on it. Anchor bolts in the wrong location, a pad that is out of level, a missing grounding stub on a transformer pad, or a pad that has settled because the subgrade was not prepared — each of these turns into a multi-day setback once the equipment arrives on site. The requirements that follow govern the conditions necessary to receive equipment without rework: correct dimensions and layout, correct anchorage to the equipment manufacturer's pattern, correct embedded items in their correct positions, and concrete that has reached sufficient strength before the equipment is set.
+
+This standard inherits the general requirements of [[syncs/cast-in-place-concrete]] for concrete materials, mix design, placement, and quality control. It inherits the requirements of [[syncs/concrete-reinforcement]] for reinforcing steel materials, fabrication, placement tolerances, and cover. It inherits the requirements of [[syncs/aggregate-base-course]] for the base course on which the pad bears and the requirements of [[syncs/earthwork]] for subgrade preparation. Where this standard adds requirements specific to equipment pads — anchorage, embedded grounding, coordination with equipment manufacturer dimensions, finish, and isolation from adjacent flatwork — those requirements supplement and do not replace the parent standards. Where this standard and a parent standard conflict, the more stringent requirement shall govern.
+
+This standard does not address the structural design of the pad itself. Pad thickness, reinforcement, and pad dimensions shown on the contract drawings are the design basis. The Contractor shall not reduce pad thickness, reduce reinforcement, or alter pad dimensions without written approval from the Engineer of Record. Default values in this specification represent typical conditions for the 80% case (a 6 in. thick pad reinforced with #4 bars at 12 in. on center each way, top and bottom, with ASTM F1554 Grade 36 cast-in-place anchor bolts) and are not a substitute for project-specific structural design.
+
+# Referenced Standards
+
+Materials, fabrication, and installation shall comply with the latest adopted edition of the following standards and codes. Where the contract documents, the adopted building code, or a referenced standard conflict, the more stringent requirement shall govern unless the Engineer of Record directs otherwise in writing.

+# Submittals
+
+## Action Submittals
+
+The Contractor shall submit the following for the Engineer of Record's review prior to procurement, fabrication of reinforcement, and concrete placement. No pad shall be placed until the corresponding submittals have been reviewed and returned.
+
+- Concrete mix design for the pad concrete class, prepared in accordance with [[syncs/cast-in-place-concrete]], showing cementitious materials, aggregates, admixtures, water content, target water-to-cementitious materials ratio, and the trial batch or field-record documentation establishing the required average strength
+- Reinforcing steel shop drawings and bar lists conforming to [[syncs/concrete-reinforcement]], showing bar sizes, grades, lengths, bends, spacing, and concrete cover for each pad type
+- Anchor bolt setting drawings, prepared from the equipment manufacturer's certified anchorage pattern for the specific equipment being supported, showing anchor bolt grade, diameter, embedment length, projection above pad, bolt circle or rectangular pattern dimensions, sleeve or template details, and the orientation of the pattern relative to the building grid or compass direction
+- Formwork shop drawings or product data for proprietary pad forming systems, including provision for chamfer at exposed edges
+- Embedded item layout for each pad type, including conduit stub-ups (size, material, count, orientation), grounding electrode connections (where required), drainage provisions (where required), and any equipment manufacturer-required cooling pits, oil-containment recesses, or cable trenches
+- Curing materials and procedure
+- For transformer pads: the grounding system layout, including ground rod locations, ground ring conductor (where used), and the connection of the grounding electrode conductor to the pad embed

+ - "Transformer pad grounding layout (where applicable)"
+default: "Anchor bolt setting drawings (per equipment manufacturer pattern)"
+```
+
+## Coordination Submittals
+
+The anchor bolt setting drawing is the most consequential submittal for an equipment pad and shall not be inferred from a generic equipment cut sheet. The Contractor shall obtain the equipment manufacturer's certified anchorage drawing for the actual ordered equipment — including the actual generator frame, the actual transformer base, the actual chiller unit — and shall not place anchors based on a catalog footprint, a model-family generic, or a "typical" arrangement. Differences in frame size, fuel tank configuration, mounting accessory, or shipping split between catalog and ordered equipment routinely move anchor bolt positions by inches; a pattern poured to the wrong drawing requires demolition and replacement of the pad.
+
+```datasheet

+options:
+ - "Equipment manufacturer's certified anchorage drawing for the ordered equipment (required)"
+ - "Catalog footprint or generic family drawing (not acceptable)"
+default: "Equipment manufacturer's certified anchorage drawing for the ordered equipment (required)"
+```
+
+## Closeout Submittals
+
+The Contractor shall provide the following at substantial completion before pad work is accepted:
+
+- As-built dimensions of each pad: plan dimensions, finished top-of-pad elevation, and the as-set anchor bolt pattern measured between bolt centers
+- Field test reports for the pad concrete (compressive strength cylinders) indexed to the corresponding pad
+- Documentation of any deviation from the approved anchor bolt pattern or embedded item layout and the Engineer of Record's written disposition
+
+# Quality Assurance
+
+## Testing Agency
+
+Concrete testing for equipment pads shall be performed by the project's concrete testing agency qualified per [[syncs/cast-in-place-concrete]]. Compressive strength cylinders shall be cast from each pad placement in accordance with that standard; a single small pad does not require a full set of cylinders if it is placed from the same truck as a larger element that is tested, but each truck delivered shall be sampled at least once per ACI SPEC-301.
+
+## Special Inspection
+
+Special inspection requirements for the pad shall be as set out in the project Statement of Special Inspections and in IBC Chapter 17. Where the equipment supported is regulated (life-safety generators, fire pumps, designated seismic equipment), pre-installation verification of the anchor pattern, anchor embedment, and pad dimensions shall be performed by the Special Inspector before equipment is set.
+
+```datasheet
+label: Pre-Set Verification of Anchor Pattern
+type: radio
+options:
+ - "Required — Special Inspector or qualified survey before equipment delivery"
+ - "Required — Contractor self-verification documented in writing"
+ - "Not required — no regulated equipment supported"
+default: "Required — Special Inspector or qualified survey before equipment delivery"
+```
+
+## Pre-Pour Conference
+
+For project sites with more than five equipment pads, or for sites with any single pad supporting equipment heavier than 5,000 lb, a pre-pour conference shall be held attended by the Contractor's superintendent, the concrete subcontractor, the equipment installer, the electrical subcontractor (where embedded conduits or grounding are involved), and the Engineer of Record. The conference shall review the approved anchor bolt setting drawings, the embedded item layout, the relationship of pad finished elevation to surrounding grade and the building floor, the curing duration before equipment may be set, and the procedure for receiving and verifying the equipment manufacturer's anchor template.
+
+# Environmental and Service Conditions
+
+Equipment pads located outside the building envelope are exposed to weather and, in cold-climate regions, to freeze-thaw cycling and de-icing chemicals carried in from adjacent driveways and walks. The exposure category selected for the pad concrete shall reflect these conditions and shall not be reduced because the pad is "isolated" or "not part of the structure." The most common durability defect in equipment pads is concrete specified without air entrainment in a freeze-thaw region, which spalls progressively at edges and corners until anchor cover is reduced or the bearing surface becomes uneven.
+
+```datasheet

+ - "Interior, in conditioned mechanical or electrical room (use parent CIP standard)"
+default: "Exterior, on grade — exposed to weather"
+```
+
+# Coordination with Equipment Manufacturer
+
+## Equipment Selection Confirmed Before Pad Construction
+
+No pad shall be formed until the equipment manufacturer and model number have been confirmed, the equipment has been released for fabrication, and the equipment manufacturer's certified anchorage drawing has been received and reviewed. Pads built on the assumption that the eventually-ordered equipment will conform to a basis-of-design drawing are at significant risk of dimension error.
+
+## Anchor Pattern Sources of Error
+
+The following are the most common sources of anchor pattern errors and shall be addressed in the Contractor's pre-pour verification:
+
+- Equipment ordered with a non-standard skid, base, or sub-base (most generators above 60 kW)
+- Equipment ordered with manufacturer accessories that change the footprint (sub-base fuel tank, vibration isolators, weatherproof enclosure)
+- Equipment with multiple shipping splits that recombine on site (large chillers, oversize switchgear lineups)
+- Field-bolted lineups where the as-shipped lineup length differs from the lineup planned during design
+- Pad-mounted transformer base footprints, which vary between utility-owned and project-owned units even at the same kVA rating
+- Imperial-vs-metric anchor pattern dimensions on equipment from international manufacturers
+
+## Anchor Template
+
+The Contractor shall use a rigid anchor template (steel, plywood, or proprietary template) to position anchor bolts during the pour. The template shall be fabricated from the certified anchorage drawing, not from a tape-measure layout of bolt positions. The template shall hold bolts vertical and at correct elevation during placement and consolidation, and shall remain in place until the concrete has set sufficiently to maintain anchor position.
+
+```datasheet
+label: Anchor Bolt Template Type
+type: radio
+options:
+ - "Steel plate template fabricated from manufacturer's anchorage drawing"
+ - "Plywood template fabricated from manufacturer's anchorage drawing"
+ - "Manufacturer-supplied template (where provided with equipment)"
+ - "Proprietary anchor bolt setting kit"
+default: "Steel plate template fabricated from manufacturer's anchorage drawing"
+```
+
+# Subgrade Preparation
+
+The subgrade beneath an equipment pad on grade shall be prepared in accordance with [[syncs/earthwork]] and shall receive an aggregate base course in accordance with [[syncs/aggregate-base-course]]. The Contractor shall not place a pad directly on natural undisturbed soil unless the geotechnical report specifically authorizes it for the soil type encountered and the equipment loading anticipated.
+
+The aggregate base course beneath the pad shall be at least as thick as the base course shown on the contract drawings, but in no case less than 4 in. for light equipment (condensing units, small pumps) and 6 in. for heavier equipment (generators, transformers). The base shall be compacted to the density required by [[syncs/aggregate-base-course]] and shall be proof rolled before the pad is formed.
+
+```datasheet
+label: Aggregate Base Course Thickness Beneath Pad
+type: select
+unit: in
+drawing_ref: true
+options:
+ - "4 in. (light equipment, condensing units, small pumps)"
+ - "6 in. (standard, generators and transformers)"
+ - "8 in. (heavy equipment, large generators, soft subgrade conditions)"
+ - "12 in. (per geotechnical report or contract drawings)"
+default: "6 in. (standard, generators and transformers)"
+```
+
+The subgrade and base course shall be moist (not saturated) at the time of pad placement to prevent the base from drawing water from the fresh concrete. Where dry or hot weather conditions are anticipated, the base shall be lightly sprinkled before placement; standing water shall not be permitted.
+
+# Formwork
+
+## Form Materials
+
+Formwork for equipment pads shall be plywood, steel, aluminum, or proprietary pad forming systems sized to the pad dimensions. Forms shall be tight enough to prevent loss of cement paste and shall be braced sufficiently to resist the hydrostatic pressure of fresh concrete without bulging beyond the ACI 117 tolerance on plan dimensions. Earth forms (concrete poured directly against trenched soil walls) are not acceptable for equipment pads because they do not maintain dimension and do not produce the chamfered or formed edges required at exposed corners.
+
+```datasheet
+label: Form Material
+type: radio
+options:
+ - "Plywood (structural-grade) with timber framing"
+ - "Steel forms"
+ - "Aluminum forms"
+ - "Proprietary pad forming system"
+default: "Plywood (structural-grade) with timber framing"
+```
+
+## Chamfer
+
+All exposed edges and corners of the pad shall be formed with a 3/4 in. chamfer unless otherwise indicated on the contract drawings. Chamfered edges reduce the likelihood of impact spalling, hide minor edge irregularities, and present a finished appearance. Sharp 90-degree corners are vulnerable to chipping under foot traffic, equipment carts, snow shovels, and de-icing salt exposure.
+
+```datasheet
+label: Edge Chamfer
+type: select
+unit: in
+options:
+ - "3/4 in. chamfer at all exposed edges (standard)"
+ - "1 in. chamfer (heavy traffic or vehicle-adjacent pads)"
+ - "Tooled radius edge (where smooth profile is required)"
+ - "Square edge (only where chamfer would conflict with equipment skirt)"
+default: "3/4 in. chamfer at all exposed edges (standard)"
+```
+
+## Form Release
+
+Form release agent shall be applied to all form surfaces before placing reinforcement. Form release shall be compatible with any subsequent coating or sealer that will be applied to the pad surface. Diesel fuel and used motor oil shall not be used as form release.
+
+# Concrete Mix
+
+The concrete mix shall conform to [[syncs/cast-in-place-concrete]] and to the additional requirements below. The pad concrete is typically a single class used throughout all pads on the project; where pad applications differ significantly (e.g., a light condensing-unit pad and a heavy generator pad), separate mix classes may be specified.

+default: "Required — 6.0% ± 1.5% (3/4 in. max aggregate, F1 or F2 — standard)"
+```
+
+Air entrainment is the primary defense against freeze-thaw spalling of edges and corners. Exterior pads in any region that experiences a freezing winter shall be air-entrained without exception. Specifying f'c alone does not provide freeze-thaw durability; an unentrained 5000 psi pad spalls just as readily as an unentrained 3000 psi pad.

+```
+
+# Reinforcement
+
+Reinforcement shall be furnished, fabricated, and placed in accordance with [[syncs/concrete-reinforcement]]. The default reinforcement for an equipment pad is a top and bottom mat of deformed bars in each direction, sized and spaced as shown on the contract drawings. Where the contract drawings do not specify reinforcement, the default below shall apply.

+```
+
+Reinforcement shall be supported on plastic-tipped wire chairs, all-plastic chairs, or precast concrete block chairs in accordance with [[syncs/concrete-reinforcement]]. Bare wire chairs shall not be used in exterior or F1/F2 exposure pads because they corrode and stain the pad surface. Bars shall be tied at intersections sufficiently to maintain position during anchor bolt installation and concrete consolidation.
+
+The reinforcing mat shall be positioned to avoid conflict with anchor bolts and conduit stubs. Where an anchor bolt or conduit conflicts with a planned bar position, the bar shall be cut and replaced with two bars splayed around the embed, splice length per [[syncs/concrete-reinforcement]]; bars shall not simply be omitted at conflicts.
+
+# Anchor Bolts
+
+## Material and Grade
+
+Anchor bolts shall be ASTM F1554 headed or hooked anchor rods, of the grade required by the structural drawings and the equipment manufacturer's anchorage drawing. ASTM F1554 Grade 36 is the default for general-purpose equipment anchorage; Grade 55 is used where structural calculations require higher capacity; Grade 105 is used for high-load applications such as large transformer anchorage in high-seismic regions and is rarely required for general equipment pads.

+```
+
+Embedment length shall be the greater of the value shown on the equipment manufacturer's anchorage drawing and the value calculated by the Engineer of Record under ACI 318 Chapter 17 for the design loads. The Contractor shall not reduce embedment depth to fit a thinner pad without written approval from the Engineer of Record and a revised anchorage calculation.
+
+## Cast-in-Place vs. Post-Installed Anchors
+
+Cast-in-place anchor bolts placed in the wet concrete during the pad pour are the default for new equipment pads. Cast-in-place bolts provide the highest pullout capacity, do not depend on epoxy or expansion mechanisms, and are not subject to seismic anchor reductions that apply to many post-installed anchors. Post-installed anchors (mechanical expansion or adhesive) are an acceptable alternative only where the pad already exists, where the anchor pattern is being changed to receive different equipment than originally planned, or where field tolerances cannot be met by cast-in-place installation.
+
+```datasheet
+label: Anchor Bolt Installation Method
+type: radio
+options:
+ - "Cast-in-place during pad pour (standard, required for new pads)"
+ - "Adhesive (epoxy) anchor in existing pad — requires Engineer approval and certified anchor system"
+ - "Mechanical expansion anchor in existing pad — requires Engineer approval"
+default: "Cast-in-place during pad pour (standard, required for new pads)"
+```
+
+Where post-installed anchors are used, the anchor product shall be certified under ICC-ES AC308 (adhesive) or AC193 (mechanical), shall be selected by the Engineer of Record for the design loads and exposure, and shall be installed by an installer who has completed the manufacturer's certification training for that anchor system.
+
+## Anchor Bolt Projection and Hardware
+
+Each anchor bolt shall project above the finished pad surface as required by the equipment manufacturer's drawing to engage the equipment base, threaded into a leveling nut and a top nut over a hardened washer per ASTM F436. The projection length shall include the equipment base thickness, the grout bed depth (where used), two washers, and the top nut, plus 1/4 in. minimum thread engagement beyond the top nut. Insufficient projection forces field cutting of bolts, which damages threads and is grounds for rejection of the installation.

+options:

+ - "3 in. (typical, generators and switchgear)"
+ - "4 in. (typical, transformers with elevated base)"
+ - "6 in. (elevated mounting or grouted bedding)"
+default: "Per equipment manufacturer drawing"
+```
+
+Anchor bolt threads above the pad surface shall be protected from damage and contamination during the curing period and through equipment delivery by capping with plastic thread protectors, by wrapping with tape and plastic, or by greasing and wrapping. Threads encrusted with concrete or rusted from neglect are a common cause of delayed equipment setting and shall be cleaned and tested before equipment is set.
+
+# Embedded Items
+
+## General
+
+All embedded items — conduits, grounding electrode conductors, drains, sleeves — shall be positioned and secured before the pad is poured. Field cutting or coring of placed pad concrete to add a missed embed shall not be performed without written approval from the Engineer of Record, because coring after the fact frequently cuts reinforcement or anchor embedment.
+
+## Conduit Stubs
+
+Conduit stubs serving the equipment shall enter the pad from below per the contract drawings and shall be terminated above the finished pad surface as required by the equipment manufacturer for that conduit connection. Conduit type and material shall conform to [[syncs/raceways-and-conduit]]. Conduit shall be capped during concrete placement to prevent debris from entering and shall be supported to resist displacement during pour.

+ - "Stop flush with pad surface (cable troughs, switchgear with internal raceways)"
+ - "Stub up 4 to 6 in. above pad (typical for terminations inside equipment base)"
+ - "Stub up to coordinate with equipment cable management"
+default: "Per equipment manufacturer's conduit entry detail"
+```
+
+Where conduits are clustered (e.g., multiple feeders entering a generator or a transformer secondary), the cluster spacing shall match the manufacturer's cable trough opening; conduits shall not foul the equipment base.
+
+## Grounding Electrode Connections
+
+Pad-mounted transformer pads, generator pads, and switchgear pads commonly require a grounding electrode connected at the pad. Grounding shall be provided in accordance with [[syncs/grounding-and-bonding]] and, for substation-class transformer installations, in accordance with IEEE 80.
+
+```datasheet
+label: Embedded Grounding at Equipment Pad
+type: checkbox
+options:
+ - "Ground rod(s) driven adjacent to pad with grounding electrode conductor stubbed through pad"
+ - "Ground ring conductor encircling pad below grade with taps stubbed through pad"
+ - "Grounding electrode conductor connection to building grounding electrode system"
+ - "Concrete-encased electrode (Ufer ground) where pad reinforcement is bonded and connected"
+ - "Not applicable — equipment connected to building grounding system only"
+default: "Ground rod(s) driven adjacent to pad with grounding electrode conductor stubbed through pad"
+```
+
+For pad-mounted transformers, the grounding electrode conductor shall stub through the pad at the location designated on the manufacturer's anchorage and grounding drawing and shall be left of sufficient length to terminate inside the transformer tank or at the equipment ground bus per [[syncs/grounding-and-bonding]]. Coiling excess conductor inside the pad cavity is acceptable provided the coil does not interfere with cable termination.
+
+For generator pads, the grounding electrode conductor connection shall be coordinated with the generator manufacturer's grounding lug location, with the building grounding electrode system, and with the separately derived system grounding requirements of NFPA 70 Article 250.
+
+## Other Embedded Items

+ - "None"
+default: "None"
+```
+
+# Pad Dimensions and Layout
+
+## Plan Dimensions
+
+Pad plan dimensions shall be as shown on the contract drawings or as determined by the equipment footprint plus the working clearance offset required by code, whichever is greater. Where the contract drawings show a pad dimensioned with [[drawing: pad plan dimensions]], that dimension is the design basis and shall not be reduced.
+
+```datasheet
+label: Pad Plan Dimensions
+type: text
+drawing_ref: true
+default: "Per [[drawing: pad plan dimensions]] — typically equipment footprint plus required offset"
+```
+
+The pad shall extend beyond the equipment footprint by the offset required to provide:
+
+- Foot clearance for service personnel walking around the equipment
+- NEC 110.26 working space dimensions in front of electrical equipment where the working space is to be on the pad rather than on adjacent paving (typically 36 in. for 0–150 V to ground, more for higher voltages)
+- A minimum 3 in. concrete edge beyond the outermost anchor bolt to prevent breakout of the anchor cone
+- Manufacturer-required clearance for cable bending radius at conduit stub-ups, control panel doors, and removable covers
+
+```datasheet
+label: Working Space Considerations
+type: checkbox
+options:
+ - "NEC 110.26 working space on the pad (typically 36 in. minimum front, 0–150 V)"
+ - "NEC 110.26 working space on adjacent paving (pad limited to equipment footprint plus 3 in. edge)"
+ - "Manufacturer-required service clearance integrated into pad"
+ - "Cable bending radius envelope at conduit stub-ups"
+default: "NEC 110.26 working space on adjacent paving (pad limited to equipment footprint plus 3 in. edge)"
+```
+
+The choice between providing the NEC working space on the pad versus on adjacent paving is a design decision that affects both pad size and the location of nearby site work (curbs, fences, landscaping). The Engineer of Record shall confirm which condition applies before the pad is dimensioned.
+
+## Pad Thickness
+
+```datasheet
+label: Pad Thickness
+type: select
+unit: in
+drawing_ref: true
+options:
+ - "4 in. (light equipment only — condensing units, small pumps)"
+ - "6 in. (standard, most equipment pads)"
+ - "8 in. (medium-heavy equipment, generators ≤ 200 kW, transformers ≤ 750 kVA)"
+ - "10 in. (large transformers, generators 200–500 kW)"
+ - "12 in. or more (heavy generators ≥ 500 kW, large transformers, per drawings)"
+default: "6 in. (standard, most equipment pads)"
+```
+
+Pad thickness governs anchor embedment, breakout cone development, and stiffness against equipment-induced vibration. Reducing pad thickness without re-evaluating anchorage is not permitted.
+
+## Top-of-Pad Elevation
+
+The finished top-of-pad elevation shall be set above adjacent grade or adjacent paving such that surface drainage flows away from the pad and that the pad is not submerged under rain or snowmelt. A minimum 4 in. elevation above adjacent grade is typical for transformer and generator pads; a minimum 2 in. is typical for condensing-unit pads on paved areas.
+
+```datasheet
+label: Top-of-Pad Elevation Above Adjacent Grade or Paving
+type: select
+unit: in
+drawing_ref: true
+options:
+ - "2 in. (standard, condensing units on paved areas)"
+ - "4 in. (standard, generator and transformer pads on grade)"
+ - "6 in. (heavy equipment, areas with high snow accumulation)"
+ - "Per [[drawing: pad section]]"
+default: "4 in. (standard, generator and transformer pads on grade)"
+```
+
+The pad shall be located by reference to the building grid, property line, or other surveyable control as shown on the contract drawings at [[drawing: pad location plan]]. Pad rotation (orientation of the equipment relative to compass direction or building face) shall match the contract drawings and the equipment manufacturer's recommended orientation for cable access, ventilation intake and exhaust, and service access.
+
+# Pour and Consolidation
+
+## Placement Method
+
+For most equipment pads, concrete shall be placed by direct chute from a ready-mix truck or by concrete pump. Free-fall distance shall not exceed 4 ft. Buggy or wheelbarrow placement is acceptable for small pads not accessible by truck or pump. Placement shall conform to [[syncs/cast-in-place-concrete]].
+
+```datasheet
+label: Placement Method
+type: radio
+options:
+ - "Direct chute from truck"
+ - "Concrete pump"
+ - "Buggy or wheelbarrow (small inaccessible pads)"
+default: "Direct chute from truck"
+```
+
+## Anchor Bolt and Embed Verification Immediately Before Pour
+
+Immediately before placing concrete, the Contractor shall verify, in the presence of the Special Inspector (where required) or by self-inspection (where not required), that:
+
+- Anchor bolts are correctly positioned per the template and the manufacturer's anchorage drawing, including pattern dimensions, pattern orientation, and bolt elevation
+- All anchor bolts are vertical and at the correct projection
+- Conduit stubs are capped, positioned, and braced
+- Grounding electrode conductors are positioned and protected
+- Reinforcement is in place, supported, tied, and at the correct cover
+- The base course is moist and free of standing water
+- Forms are tight, braced, and treated with release agent
+
+The pre-pour verification shall be documented in writing. Concrete shall not be placed until any deficiencies are corrected.
+
+## Consolidation
+
+Concrete shall be consolidated by internal mechanical vibration immediately after placement. A vibrator head of 1-1/2 to 2 in. diameter is appropriate for most equipment pads; the vibrator shall be inserted at intervals not exceeding 18 in. and shall be held until air bubbles cease rising. The vibrator shall not be used to move concrete laterally or to drag concrete into corners. Care shall be taken not to displace anchor bolts during vibration; the anchor template shall be braced sufficiently to resist incidental contact.
+
+```datasheet
+label: Internal Vibrator Head Diameter
+type: select
+unit: in
+options:
+ - "1 in. (thin pads, congested embeds)"
+ - "1-1/2 in. (standard equipment pad)"
+ - "2 in. (heavy pad, sparse embeds)"
+default: "1-1/2 in. (standard equipment pad)"
+```
+
+# Finish
+
+## Top Surface
+
+The top surface of an equipment pad shall be screeded to elevation, floated to consolidate the surface and embed coarse aggregate, and finished to the texture appropriate for the equipment that will be set on it.
+
+```datasheet
+label: Top-of-Pad Finish
+type: radio
+options:
+ - "Steel-troweled smooth — equipment with continuous base, no grout bed"
+ - "Wood-floated — equipment requiring a grout bed for leveling"
+ - "Light broom — pedestrian traffic on or alongside the pad"
+ - "Heavy broom — equipment that may be walked on during service"
+default: "Steel-troweled smooth — equipment with continuous base, no grout bed"
+```
+
+Steel troweling is the default for equipment with a continuous, machined base that bears directly on the pad. A wood-floated surface is preferred where the equipment is leveled on a grout bed, because the rougher texture improves grout bond. A broom finish is required for any surface that a worker may stand on, particularly transformer pads in regions subject to ice.
+
+The top surface shall not be steel-troweled to a glass-smooth finish where equipment will be set on a grout bed; over-troweling produces a dense, low-permeability surface to which grout does not bond well.
+
+## Tolerances on Top Surface
+
+The top surface shall be level within the tolerances given under Tolerances below, and shall be free of high spots, low spots, and trowel ridges that would prevent uniform bearing of the equipment base on the pad or grout bed.
+
+# Curing and Protection
+
+Curing shall conform to [[syncs/cast-in-place-concrete]] and ACI 308R. Equipment pads are particularly vulnerable to inadequate curing because their high surface-to-volume ratio causes rapid moisture loss; an uncured pad develops a weak, dusty, permeable surface that subsequently spalls in freeze-thaw exposure.
+
+```datasheet
+label: Curing Method
+type: radio
+options:
+ - "Curing compound (ASTM C309 Type 1-D or Type 2)"
+ - "Wet burlap covered with polyethylene sheeting"
+ - "Polyethylene sheeting only (interior pads, low evaporation)"
+ - "Insulated curing blanket (cold weather)"
+default: "Curing compound (ASTM C309 Type 1-D or Type 2)"
+```
+
+Curing compound shall not be applied to areas where a grout bed, sealer, or coating will subsequently be applied unless the curing compound is demonstrated to be compatible or has fully dissipated before the subsequent application. Where compatibility cannot be confirmed, wet curing shall be used.
+
+```datasheet
+label: Curing Duration Before Equipment May Be Set
+type: select
+unit: days
+options:
+ - "3 days — light equipment, no operational loading (condensing units)"
+ - "7 days — standard, most equipment"
+ - "14 days — heavy equipment, transformers under load, high-vibration generators"
+ - "Per field-cured cylinder breaks demonstrating 75% of f'c"
+default: "7 days — standard, most equipment"
+```
+
+The pad shall not be loaded with equipment until concrete has reached at least 75% of f'c, demonstrated by field-cured cylinder breaks taken from the same pour. Setting equipment on uncured concrete is among the most common causes of cracking at anchor bolts and edge spalling.
+
+```datasheet

+default: "Not required — ambient > 40°F through protection period"
+```
+
+# Tolerances
+
+Dimensional tolerances shall comply with ACI 117. Equipment pad tolerances are typically tighter than generic slab tolerances because the pad serves as a bearing and anchorage surface for equipment with specified mounting points.
+
+```datasheet
+label: Plan Dimension Tolerance
+type: select

+ - "Within 1 in 100 (0.6 degrees) of vertical — high-precision equipment"
+default: "Within 1 in 40 (1.5 degrees) of vertical"
+```
+
+The pattern tolerance shall be measured against the equipment manufacturer's drawing, not against a tape-measure layout of nominal dimensions. Where pattern tolerance is exceeded, the Contractor shall not bend, heat, or cut anchor bolts to fit the equipment without written approval from the Engineer of Record; the resolution is either to ream the equipment base or to remove and replace the pad.
+
+# Joints — Isolation from Adjacent Flatwork
+
+Where an equipment pad is placed adjacent to a sidewalk, driveway, exterior slab, or building floor slab, an isolation joint shall be provided between the pad and the adjacent flatwork. The pad and the adjacent slab move differently because of differential loading, thermal cycling, and subgrade differences, and a rigid connection between them produces cracking at the interface. Isolation joints shall be full-depth pre-molded joint filler in accordance with [[syncs/cast-in-place-concrete]].
+
+```datasheet
+label: Isolation Joint at Adjacent Flatwork
+type: radio
+options:
+ - "Required — full-depth pre-molded joint filler at all interfaces with adjacent slabs or paving"
+ - "Not applicable — pad is freestanding with no adjacent flatwork"
+default: "Required — full-depth pre-molded joint filler at all interfaces with adjacent slabs or paving"
+```
+

+label: Isolation Joint Filler
+type: radio
+options:
+ - "Closed-cell polyethylene foam filler, compressible (standard)"
+ - "Asphalt-impregnated fiber filler"
+ - "Per contract drawings"
+default: "Closed-cell polyethylene foam filler, compressible (standard)"
+```
+
+The joint shall be sealed at the surface with an elastomeric joint sealant where the joint is exposed to traffic, water, or where its open condition would be unsightly. The sealant shall be compatible with the joint filler and shall be installed in accordance with the sealant manufacturer's instructions.
+
+Construction joints within a single pad shall be avoided. A pad shall be placed monolithically; cold joints, partial placements, or layered pours produce planes of weakness that are not acceptable in an equipment foundation.
+
+# Inspection and Testing
+
+## Pre-Placement Inspection
+
+Pre-placement inspection requirements are stated above under Pour and Consolidation.
+
+## Field Testing of Concrete
+
+Field testing of fresh concrete (slump, air content, temperature) and casting of compressive strength cylinders shall be performed in accordance with [[syncs/cast-in-place-concrete]]. For project sites with multiple pads placed from a common pour, a single set of acceptance cylinders may serve multiple pads provided the placements occur on the same day from the same delivered concrete.
+
+## Pre-Set Verification
+
+Before equipment is set on a pad, the Contractor shall verify and document:
+
+- Pad concrete has reached at least 75% of f'c
+- Anchor bolt pattern dimensions and projections match the equipment manufacturer's anchorage drawing within the specified tolerance
+- Anchor bolt threads are clean, undamaged, and capable of accepting the leveling nut and top nut
+- Top-of-pad elevation and levelness are within tolerance
+- Embedded conduits and grounding stubs are present, clean, and at the correct locations
+- The pad is free of cracks, spalls, exposed reinforcement, or other defects
+
+```datasheet
+label: Pre-Set Verification Required Before Equipment Delivery
+type: radio
+options:
+ - "Yes — written verification by Contractor with sign-off"
+ - "Yes — Special Inspector observation in addition to Contractor verification"
+default: "Yes — written verification by Contractor with sign-off"
+```
+
+The pre-set verification protects against the most expensive sequence of failures in equipment installation: equipment delivered to the site, equipment found not to fit, equipment returned to storage at additional cost, pad demolished and replaced, equipment re-delivered. Verification before delivery is inexpensive; the failure mode after delivery is not.
+
+# Delivery, Storage, and Handling of Materials
+
+Reinforcing steel shall be delivered, stored, and handled in accordance with [[syncs/concrete-reinforcement]]. Anchor bolts shall be delivered to the site in clearly identified bundles or boxes with manufacturer's certification (mill test reports for the bolt steel and zinc coating thickness verification for galvanized bolts) and shall be stored on supports above grade in a manner that prevents thread damage and contamination. Thread protectors shall remain in place from delivery through installation.
+
+Concrete shall be delivered in accordance with ASTM C94 and [[syncs/cast-in-place-concrete]]. Curing compounds, form release, and curing blankets shall be stored in accordance with the manufacturer's recommendations, protected from freezing and from exposure to sunlight where the product is light-sensitive.
+
+# Repair of Defects
+
+Defects discovered after form stripping or after pad acceptance shall be evaluated by the Engineer of Record and repaired as directed. Common defects in equipment pads and their typical dispositions:
+
+| Defect | Typical Disposition |
+|--------|---------------------|
+| Hairline shrinkage cracks (< 0.005 in.) | Accept; seal with penetrating sealer if in F2 exposure |
+| Surface cracks > 0.005 in. but not through-thickness | Rout and seal with elastomeric crack sealant |
+| Through-thickness cracks | Engineer evaluation; epoxy injection or replacement |
+| Edge or corner spall | Repair with polymer-modified patching mortar to original profile |
+| Honeycombing in formed surface | Remove loose material, dampen, patch with mortar of same w/cm as parent concrete |
+| Anchor bolt out of pattern tolerance | Engineer evaluation; ream equipment base, relocate bolt, or replace pad |
+| Anchor bolt out of plumb | If within recoverable range, straighten with leveling nut and shim; otherwise replace pad |
+| Embedded conduit missing or wrong location | Core after the fact only with Engineer approval; otherwise modify equipment layout or replace pad |
+
+The Contractor shall not perform structural repairs (epoxy injection, replacement, anchor relocation) without written direction from the Engineer of Record. Cosmetic repairs to non-structural surface defects may proceed in accordance with [[syncs/cast-in-place-concrete]].

+```
+
+# Warranty
+
+The Contractor shall warrant the pad installation against defects in materials and workmanship — including cracks beyond hairline width, surface spalling, anchor displacement, settlement, and frost heave — for the project warranty period from the date of substantial completion. The warranty shall not apply to damage caused by equipment loads exceeding the design basis, to damage from vehicle impact or other external causes, or to settlement caused by subgrade conditions outside the Contractor's scope.
