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.
Close out the job — punch, package, retention, done
Clear the punch list, file the closeout documents so the package assembles itself, issue substantial completion, and bill retention on the final application with the §8138 waiver behind it.
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.
Work a warranty callback — log it, fix it, keep the lesson
Log a warranty item against the one-year clock, send someone out with a date and a bucket, close it with a root cause, and file the lesson where the next estimate will find it.
