Walk me through how you'd bill a sprinkler install for a general contractor on a monthly pay application, including retainage.

Technical · Progress billing and retainage

Strong answer

Bills against the schedule of values using the percent complete the project manager confirms, tracks retainage receivable separately, sends lien waivers with each bill, and follows up on retainage at closeout.

Red flags

Invoices the full contract at the end, or loses track of retainage owed.

Walk me through how you handle lien waivers on a commercial job, both the ones we give the general contractor and the ones we collect from suppliers.

Technical · Lien waivers

Strong answer

Sends conditional waivers with pay applications and unconditional ones only after payment clears, uses the state's required forms where they exist, collects supplier waivers when paying them, and keeps a log by job.

Red flags

Doesn't know the difference between conditional and unconditional waivers, or signs whatever arrives.

Searches likely spots and trucks, calls the supplier for a fast order, tells the tech and dispatcher the real status, and fixes the count error.

Red flags

Tells the tech it's in stock and hopes it turns up.

A shipment arrives with the right part numbers on the boxes, but some heads inside have a different temperature rating than the packing slip. What do you do?

Situational · Receiving inspection

Strong answer

Sets them aside, checks the rest of the shipment, documents it with photos, and notifies the supplier and purchaser before anything goes on a shelf or truck.

Red flags

Stocks them anyway because the box label is right.

A manufacturer recalls a sprinkler model your company stocks and has installed. What would you do from the inventory side?

Red flags

Skipped a step, like the full hydro hold, a main drain test or an impairment notice, to save time and sees nothing wrong with it.

Tell me how you found the cause of the hardest system problem you've tracked down, like a dry valve that kept tripping or a waterflow alarm that wouldn't clear.

Behavioral · Troubleshooting

Strong answer

Gathers history, tests one thing at a time, rules causes in or out with evidence, and confirms the fix held on a later visit.

Red flags

Swapped parts until something worked, or can't explain why the fix worked.

Walk me through how you'd lay out and calculate a sprinkler system for a warehouse whose owner plans to store plastic goods on high racks.

Technical · Designing for the hazard

Strong answer

Asks about commodity, storage height and arrangement, picks a design approach that fits NFPA 13, checks the water supply against the hydraulic demand, and considers in-rack heads and future use.

Red flags

Uses an office design approach, or doesn't ask what will be stored.

Walk me through how you'd use a fire flow test to decide whether a building needs a fire pump.

Technical · Judging water supply

Strong answer

Gets recent static, residual and flow readings, plots the supply curve, compares it with system demand plus hose allowance and any safety margin the AHJ requires, and looks at options if it falls short.

Red flags
