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.
Bill the month — a pay app that doesn't bounce
Open the period, let the G703 build from the SOV, enter percent complete, submit to open the receivable, generate the §8132 conditional waiver, and send one package whose math ties to the SOV.
Lien waivers — the four California forms and when each is safe to sign
Conditional vs unconditional, progress vs final — the §8132–§8138 statutory forms as a two-by-two matrix, and the one rule that keeps you from waiving rights for a check that hasn't cleared.
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.
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.
