Practical knowledge for specialty contractors
Compliance, change management, project controls, and the data discipline that compounds across bids. Written for California specialty subs — owners, PMs, estimators, and the field.
Baseline vs current vs actuals — the three views every project lives in
A baseline is the promise. Current is the forecast. Actuals are the receipts. Treating them as one number is how subs miss overruns until they're paying for them.
California lien deadlines — preliminary notice, stop notice, mechanic's lien
The three deadlines that protect your right to get paid on a private California project. Miss one, lose the remedy.
Certified payroll — weekly cadence and DIR submission
When CPRs are due, what "work performed" means, and how STrOp builds the LCPtracker / eCPR export.
Closing the loop — warranty callbacks become next year's contingency
Most subs lose the warranty data trail because the callback lives in a different inbox than the estimate. The loop is short, the payoff is high, and the discipline is mostly about where the data lives.
CSLB license renewal — windows, fees, and the gotchas
When the 60-day renewal window opens, what an "active" vs "inactive" renewal means, and what STrOp warns you about.
DIR registration & renewal — California public works
Who needs to register, when annual renewal opens, and what STrOp checks before you bid a prevailing-wage job.
Earned value for trades — the four numbers that predict overruns
EVM without the certification. PV, EV, AC, and the four ratios that tell you a job is going sideways before the final pay app does.
How estimate pricing is calculated
Every estimate line runs the same four-step recipe — pad the quantity, extend by unit cost (tax on material only), add overhead then profit margin, round. Profit is a margin; overhead is a markup or a margin, set per estimate.
Import a DIR wage determination (and keep it current)
Load a California prevailing-wage determination — including its scheduled July-1-style increase — so your projects validate pay against the right floor, and refresh it when DIR reissues.
Pay app submission checklist
What goes in a monthly pay application, what the GC's reviewer looks for, and what STrOp assembles automatically.
PCO vs CO — proposal versus executed change
A PCO is your priced ask. A CO is the executed contract amendment. Until the CO is signed, the work isn't billable on a pay app.
Prevailing wage rates — how to find the right one
Which rate applies to which worker on which project, where DIR publishes them, and how STrOp pulls the right one onto your timecards.
Productivity rate capture — today's timecard becomes tomorrow's bid
The estimator's productivity assumption is the single biggest source of bid variance. The fix is a feedback loop, and the loop only works if timecard data lives in the same system as the assemblies.
Retainage release — when, how much, and what to chase
Standard 5–10% withholding through the project, partial release at substantial completion, final release after closeout. The clocks and triggers contractors miss.
RFI vs Change Event — when to file which
An RFI asks a question. A Change Event records an impact. Treating them the same is how recovery slips through the cracks.
T&M tag — why the owner signature is everything
What a T&M tag is, what makes it legally enforceable, and what STrOp does when the signature is missing.
Your estimate is your earliest budget — not the contract value
The contract value tells you what the GC owes you. The estimate tells you what the job is supposed to cost. Confusing them is how subs miss a 30% margin compression.
