Read the specification’s sequencing article for each pump (primary, secondary, pressure maintenance), then compare it with the pump schedule, riser diagram, and controller drawings, and trace the driver to its power or fuel source, the test header to an outside wall with drainage, and the pump room plan to the equipment it must hold. Electric and diesel drivers raise different questions, so confirm which one every sheet shows.
Assemble the review package
Gather the fire pump room plan, sections, and piping schematic, the pump and controller schedule, the fire protection riser diagram and water supply data, the electrical one-line and transfer switch drawings for an electric driver, the fuel tank, exhaust, and ventilation drawings for a diesel driver, the site plan for the test header discharge, and the issued Section 21 30 00. Review one pump train from suction to test header before assuming the second pump matches.
WBDG publishes UFGS 21 30 00: Fire Pumps as a public guide-specification reference (accessed October 17, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| Pump sequence | Sequencing article + controller schedule + sequence of operation | Do the specification, schedule, and controller notes describe the same start, stop, and staging logic for each pump? |
| Driver type | Electric Motor or Diesel Engine Driver article + pump schedule + room plan | Does every document show the same driver for each pump, and do the room plan and supporting systems match it? |
| Electric power path | Fire Pump Controller article + electrical one-line + transfer switch drawings | For an electric pump, is the controller fed as the one-line shows, and is any transfer switch for fire pump service identified? |
| Diesel fuel, exhaust, and batteries | Diesel Fuel System, Exhaust System, and Batteries articles + mechanical plans | For a diesel pump, are the fuel tank, fuel piping, exhaust route, combustion air, and starting batteries drawn and coordinated with the room? |
| Test header and flow meter | Hose Valve Manifold Test Header and Flow Meter articles + site and room plans | Is the test header located with access and drainage, and is the flow meter arrangement drawn as specified? |
| Valves and supervision | Valves and Tamper Switch articles + piping schematic + fire alarm plans | Are control valves, relief valves, and check valves drawn where the schematic needs them, and are their supervisory switches on the fire alarm drawings? |
| Pressure maintenance pump | Pressure Maintenance Pump article + schematic + controller schedule | Is the pressure maintenance pump and its controller drawn and sequenced with the main pumps? |
| Pump room layout | Pump Room Configuration article + room plan and sections | Does the room plan show the pumps, drivers, controllers, test header, and sensing lines the section asks to be detailed, with access around them? |
Worked example: a diesel pump specified, an electric pump drawn
Illustrative example: the issued Section 21 30 00 retains the diesel engine driver and diesel fuel system articles for the primary pump. The pump room plan shows an electric motor and a controller fed from the emergency switchboard, with no fuel tank, exhaust, or battery rack drawn.
Ask the fire protection engineer which driver is intended, then remove the unused articles from the specification or add the fuel, exhaust, ventilation, and battery work to the drawings. Recheck the electrical one-line and the pump room ventilation for the same decision before closing the item.
Avoid a false conflict
A fire pump specification often keeps both driver options until late editing. An article that survives in the issued section is still a contract requirement, so a driver mismatch is a real coordination question.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
Where Groundbook fits
Groundbook’s drawing and specification review helps investigate potential disagreements in the documents you supply. Include the relevant specification sections and drawing references, then verify the cited evidence with the responsible reviewers before acting on a finding.
