📝 Estimator's Field Note
"Seismic requirements in San Francisco go beyond the CBC minimum — the local amendments for flexible conduit connections at all seismic joints, the cable tray bracing at 6-foot intervals instead of 10, and the generator vibration isolation with seismic restraints. Each one adds cost that's easy to miss."
🔍 Scope Gap Warning
Watch for the fire alarm and security systems scope gap. Many commercial plans show fire alarm on the electrical drawings but reference separate specifications that the electrical contractor may or may not be carrying.

📦 Coordination Note from Our Team
Coordinate with the GC on the electrical room rough-in sequence. The concrete floor in the electrical room should be poured and cured before switchgear delivery, but the conduits entering the slab need to be stubbed up before the pour.
