NOTE This standard applies to all wet-pipe, dry-pipe, pre-action, deluge, standpipe, fire pump, clean-agent, and kitchen-hood fire suppression work installed under the project. (1.1.1)

NOTE The "common work results" tier sits one level above the system-specific standards in the SynC fire suppression hierarchy. Its purpose is to state the contractor qualification, submittal, coordination, labeling, seismic-basis, flushing, testing, closeout, and training provisions exactly once, so that every downstream system standard can invoke them by reference instead of restating them. When a provision here conflicts with a more specific provision in a system standard, the system standard governs for that system. (1.1.2)

NOTE Materials and physical components are deliberately out of scope here so they live in one place. (1.1.5)

NOTE This standard concerns who does the work, what they submit, how they coordinate, how the work is identified, and how it is tested and handed over. (1.1.6)

NOTE Anchorage special inspection is a statutory third-party activity tied to the building's structural permit, not a contractor self-test, so it is owned by the special-inspections standard rather than restated here. (1.1.9)

NOTE The fire suppression systems required for the project shall be those mandated by the adopted building and fire codes for the occupancy, construction type, and building height. (1.2.1)

NOTE IBC Chapter 9 and IFC Chapter 9 establish which systems are required and where. Those determinations are made by the design team during the code analysis; this standard governs the execution of whatever systems result, not the decision of which systems are required. (1.2.2)

NOTE The Contractor shall design and install all fire suppression work to the edition of each standard adopted by the Authority Having Jurisdiction, not merely the latest published edition. (1.2.4)

NOTE The 2019, 2022, and 2025 editions of NFPA 13 differ materially on pipe schedules, CPVC allowances, and seismic bracing provisions. Designing to an edition the AHJ has not adopted -- or to a newer edition than the one in force -- generates pervasive plan-review comments and field RFIs. Confirming the adopted edition in writing at the outset is the single cheapest defect to prevent. (1.2.5)

NOTE The Contractor shall submit working drawings and the supporting hydraulic calculations together as a single coordinated package. (3.1.2)

NOTE Most AHJs require the working drawings and the calculations together for plan review, because the calculations are meaningless without the layout they describe. Submitting them sequentially -- drawings now, calculations later -- stalls the permit and is one of the most common causes of avoidable schedule slip on fire suppression work. (3.1.3)

NOTE Whether a preliminary (design-intent) submittal is required before the final working-drawing submittal shall be as indicated. (3.1.5)

NOTE On fast-track and design-build projects an early design-intent submittal lets the design team confirm hazard classification and routing before the contractor invests in full working drawings. On conventional projects it is unnecessary overhead. This is a project delivery decision, not a fixed rule. (3.1.6)

NOTE The Contractor shall submit closeout documents within 30 days of system acceptance. (3.3.2)

NOTE A common dispute is the contractor delivering O&M manuals at substantial completion while the record drawings remain unfinished. The owner's facilities team cannot operate or maintain a system it cannot document, so retainage is held pending the missing drawings. Binding both deliverables to a single 30-day window after acceptance removes the gap. (3.3.3)

NOTE The fire suppression systems shall be designed by a qualified party holding the credential indicated for the project's jurisdiction. (4.1.1)

NOTE Three credentialing bases are in common use, and the correct one depends on local law. NICET certification (National Institute for Certification in Engineering Technologies) certifies the layout technician; a licensed Professional Engineer or Fire Protection Engineer seals the engineered design; and many jurisdictions additionally require a state fire-sprinkler contractor's license held by the installing firm. These are not mutually exclusive -- a project may require all three. Selecting a basis that does not match the jurisdiction's licensing law produces a design that cannot be permitted. (4.1.2)

NOTE Hydraulic calculations shall be prepared by a person holding NICET Level III certification or by a licensed Professional Engineer. (4.1.4)

NOTE The complexity threshold matters: for large or unusual systems, the engineering judgment behind a hydraulic calculation exceeds what Level II layout certification represents. Requiring Level III or a PE seal for the calculations -- while permitting Level II for routine layout -- matches the credential to the difficulty of the task. (4.1.5)

NOTE The design and installation responsibility shall follow the delivery model indicated for the project. (4.1.7)

NOTE The project must state who carries design liability. In a delegated-design model the general contractor engages a specialty subcontractor who seals the working drawings and calculations under its own PE license. In an engineer-of-record model the design team produces a fully engineered design and the contractor installs to it. In a design-build package the fire suppression subcontractor provides design, materials, installation, testing, and closeout as one scope. The model determines who stamps the drawings and the as-built record set, which is a frequent source of ambiguity if left unstated. (4.1.8)

NOTE Equipment shall be installed within the limits of its listing or approval, including pressure, temperature, and orientation limits. (4.2.2)

NOTE A listing is specific to an application. A device listed for wet-pipe service is not automatically suitable for dry-pipe or deluge service, and a component installed outside its listed pressure or orientation range is, for code purposes, unlisted. The AHJ will reject equipment used outside its listing regardless of its general quality. (4.2.3)

NOTE On FM-insured projects, all fire suppression equipment shall additionally carry FM approval and comply with the applicable FM Global Data Sheets. (4.2.4)

NOTE FM-insured owners frequently require FM approval as a condition of coverage, which is a narrower set than UL listing alone. Confirming the insurer's requirement early avoids procuring UL-only equipment that the insurer will not accept. (4.2.5)

NOTE The conference shall confirm the seismic design basis, the identification scheme, the coordination-drawing process, and the testing and acceptance sequence. (4.3.2)

NOTE The recurring coordination failures on fire suppression work -- mismatched valve numbering, unresolved overhead clashes, and out-of-sequence testing -- are all cheaper to prevent in a one-hour conference than to reconcile in the field. Confirming the seismic basis and the identification scheme here, before any pipe is hung, is the point of the meeting. (4.3.3)

NOTE The project seismic design parameters are stated below and shall be used by every fire suppression system designer. (5.1.1)

NOTE The single most common avoidable RFI on fire suppression work is the missing seismic design basis. NFPA 13 Chapter 9 seismic bracing is calibrated to ASCE 7 Chapter 13 demand, so a designer cannot size or locate a single brace without the project Sds value and the component importance factor. Stating these parameters once, here, lets every downstream system standard reference them rather than each contractor chasing them through an RFI. (5.1.2)

NOTE Fire suppression piping and equipment shall be a life-safety component and shall be assigned a component importance factor of 1.5 unless the structural engineer of record directs otherwise. (5.1.3)

NOTE Fire suppression systems are required to remain functional after a seismic event, which places them in the higher importance-factor category under ASCE 7. The default of 1.5 reflects this; a lower value is the exception and requires the structural engineer's direction. (5.1.4)

NOTE Where seismic bracing is required, it shall be designed and installed in accordance with the seismic provisions of NFPA 13 and the bracing-hardware requirements of Fire Protection Piping. (5.1.6)

NOTE This standard establishes the demand -- the Sds, the importance factor, and the threshold at which bracing is triggered. The selection and installation of the brace hardware itself belongs to the piping standard, so the two are read together: demand here, hardware there. (5.1.7)

NOTE The Contractor shall coordinate the firestopping of all fire suppression pipe penetrations through rated assemblies in accordance with Firestopping. (6.1.3)

NOTE Penetration firestopping is owned by the firestopping standard, but the fire suppression contractor must coordinate the sleeve sizes and penetration locations so the firestop system selected matches the as-built condition. Routing decided without that coordination forces field-modified penetrations that may void the firestop listing. (6.1.4)

NOTE The Contractor shall participate in the project coordination-drawing process and shall model fire suppression piping for clash detection with structure and other trades. (6.2.1)

NOTE When coordination-drawing participation is not required contractually, fire suppression piping gets routed without clash detection and conflicts with structural beams, HVAC mains, and light fixtures in nearly every overhead corridor, generating a change order at each one. Requiring participation up front is far cheaper than resolving the clashes as field changes. (6.2.2)

NOTE Pipe and fittings shall be installed clean, free of cutting burrs, scale, oil, and construction debris. (7.1.2)

NOTE Debris left inside the pipe during installation migrates to sprinkler orifices and small-bore devices, where it causes obstruction failures that surface only at the acceptance test. Keeping the interior clean during installation is the first line of defense; the flushing requirement below is the second. (7.1.3)

NOTE Sprinklers and devices removed or omitted to facilitate other work shall be reinstalled and the system restored to service before that area is enclosed. (7.2.2)

NOTE Devices pulled during construction and not reinstalled leave coverage gaps that are invisible once the ceiling is closed. Restoring the system before enclosure is the only practical opportunity to verify coverage. (7.2.3)

NOTE Pipe identification shall state the service (for example, "Fire -- Wet Sprinkler" or "Fire -- Standpipe") and shall include a directional flow arrow. (8.1.3)

NOTE The label must let a responder or maintainer read the service and flow direction at a glance, without tracing the pipe back to a riser. The service name pairs with the valve list so that any segment can be matched to its controlling valve. (8.1.4)

NOTE The valve list shall record, for each valve, its identifier, location, type, normal operating position, and the system or zone it controls. (8.2.2)

NOTE The valve list is the operational backbone of the system. NFPA 25 inspection and impairment procedures both depend on a maintainer being able to find a specific valve and know its normal position. A tag without a corresponding list entry -- or a list entry without a tag in the field -- breaks that chain. (8.2.3)

NOTE The valve numbering scheme shall be coordinated with the fire alarm valve-supervisory point list so that each supervised valve carries the same identifier in both documents. (8.2.4)

NOTE A recurring documentation failure: the electrician wires valve-tamper supervisory switches to points numbered by the fire alarm contractor, while the fire suppression contractor tags the same valves by a different scheme. The two lists then disagree, and reconciling them during AHJ inspection can take weeks. Forcing a single shared identifier removes the mismatch at the source. (8.2.5)

NOTE Record drawings and information signs shall use the fire safety symbols of NFPA 170. (8.3.2)

NOTE Standardizing on NFPA 170 symbols means a responder or inspector reads the same symbol set on the record drawings, the riser diagrams, and the building's life-safety plans, rather than a contractor-specific legend. (8.3.3)

NOTE Underground mains shall be flushed at a velocity of not less than 5 ft/s in the largest main being flushed, or at the system demand flow, whichever is greater. (9.1.2)

NOTE The 5 ft/s minimum velocity from NFPA 24 is what actually scours scale, joint lubricant, and construction debris out of a buried main. A typical 4 in. main needs roughly 390 gpm to reach that velocity, and a 6 in. main roughly 880 gpm. A flush performed below that velocity moves water but does not clean the pipe, and the debris then migrates into the aboveground system. (9.1.3)

NOTE The Contractor shall flush in the direction of normal flow and shall direct flush water to an approved point of disposal without erosion or damage to adjacent property. (9.1.4)

NOTE Flushing against normal flow can drive debris into branches that the flush was meant to clear, and unmanaged discharge of flush water erodes site work and can carry sediment into storm systems. Both the direction and the disposal point must be planned, not improvised at the hydrant. (9.1.5)

NOTE The Contractor shall not omit the underground flush or delegate responsibility for it without written confirmation that it was performed at the required velocity. (9.1.6)

NOTE A frequent field dispute is the aboveground contractor discovering debris at the acceptance test and arguing the underground flush was the civil contractor's responsibility. A written flush record at the required velocity, retained as part of the test certificates, settles that question before it becomes a claim. (9.1.7)

NOTE Water-based systems shall be hydrostatically tested at 200 psi for two hours, or at 50 psi above the maximum system working pressure where that pressure exceeds 150 psi, whichever is greater. (10.1.2)

NOTE The 200 psi / 2 hour test from NFPA 13 is the 80%-case requirement for ordinary working pressures. The alternative -- 50 psi above maximum working pressure -- only governs on high-pressure systems, typically high-rise standpipe zones and pumped systems, where 200 psi would not provide the required margin above operating pressure. (10.1.3)

NOTE A water-based system shall show no leakage and no drop in gauge pressure over the full test duration to be accepted. (10.1.4)

NOTE For welded and threaded fire protection piping the acceptance criterion is zero pressure loss over the hold -- visible or measurable leakage is a failure, not a tolerance. This is stricter than the leakage allowance permitted for some buried mains, and it is what the AHJ witnesses. (10.1.5)

NOTE The functional test shall verify that waterflow and valve-tamper signals are received and correctly annunciated at the fire alarm system. (10.2.2)

NOTE The hydrostatic test proves the pipe holds pressure; the functional test proves the system does its job -- that opening a valve or initiating flow produces the correct alarm and supervisory response at the fire alarm panel. Both are required for acceptance, and the functional test depends on the fire alarm interface being complete. (10.2.3)

NOTE The Contractor shall sequence the hydrostatic test after coordination drawings are approved and congested areas are resolved. (10.2.4)

NOTE Running the hydrostatic test before overhead coordination is settled means hanger and routing changes made afterward reopen fittings that were already tested, forcing a retest. Sequencing the test after the layout is locked avoids the rework. (10.2.5)

NOTE The Contractor shall hand over each system with the inspection, testing, and maintenance baseline of NFPA 25 documented in the O&M manual. (10.3.1)

NOTE NFPA 25 defines the weekly, monthly, quarterly, and annual ITM tasks the owner must perform to keep the system code-compliant in service. Documenting that baseline at handoff -- rather than restating it in each system standard -- gives the owner's facilities team a single ITM schedule covering every fire suppression system on the project, and it is the basis for the owner training required below. (10.3.2)

NOTE Record drawings shall be submitted at a scale of not less than 1/8 in. = 1 ft and shall reflect the as-built condition accurately enough for the owner to locate and isolate any portion of the system. (11.1.2)

NOTE The accuracy threshold is functional, not cosmetic: a maintainer must be able to use the record set to find a valve and isolate a zone during an impairment. Drawings that show the design intent rather than the as-built routing fail that test and are a common reason retainage is held. (11.1.3)

NOTE Training shall be a minimum of four hours, combining classroom instruction with a walkthrough of the installed systems. (12.1.2)

NOTE A guided walkthrough is the part facilities staff actually retain -- standing at the riser and the fire pump, finding the valves on the list, and practicing an impairment. Six months after occupancy, an undocumented or skipped training shows up as a facilities team that cannot perform the NFPA 25 weekly checks or follow an impairment procedure, which is a direct liability exposure for the owner. (12.1.3)

NOTE The owner's facilities representative shall attend the training. (12.1.5)

NOTE Training delivered to whoever happens to be on site does not transfer to the people responsible for the system. Requiring the named facilities representative ensures the ITM and impairment knowledge lands with the party who will own it. (12.1.6)

NOTE Spare stock shall be turned over to the owner and recorded on the spare-parts transmittal at closeout. (13.1.1)

NOTE Spare-sprinkler cabinets and the special wrench for each sprinkler type are required by NFPA 13 and are part of the operational handoff. Recording them on the transmittal makes the turnover auditable rather than relying on an undocumented hand-off that the owner cannot later verify. (13.1.2)
