Bid & Plan Review
We review your architectural plans, MEP drawings, and project specifications. Our estimators identify all electrical requirements: power distribution, lighting layouts, receptacle counts, and special circuits for equipment. You receive a detailed bid within 48-72 hours.
Scope Meeting
We meet with you and your general contractor to walk the space, clarify requirements, and coordinate with other trades. This is where we catch potential conflicts: HVAC penetrations, plumbing runs, or structural elements that affect our routing.
Permit Application
We pull all required electrical permits from your municipality. For St. Louis and St. Charles County commercial work, this includes submitting load calculations and one-line diagrams to the building department for approval.
Material Procurement
We order all materials (panels, conduit, wire, devices, and fixtures) based on the approved plan. Long-lead items like custom panels or specialty fixtures are identified early to prevent schedule delays.
Rough-In Installation
Our crew installs conduit, wire, and boxes according to the electrical drawings. We coordinate daily with other trades to maintain schedule. All rough-in work is photographed and documented before walls close.
Rough-In Inspection
We schedule the required rough-in inspection with the building department. The inspector verifies proper box placement, wire sizing, conduit fill, and code compliance before drywall installation can proceed.
Trim & Finish
After walls are finished, we return to install switches, receptacles, light fixtures, and panel covers. We test all circuits, verify proper operation, and ensure everything matches the specifications.
Final Inspection & Turnover
We schedule the final electrical inspection. After passing, we provide as-built drawings, panel schedules, and warranty information. We walk the space with you to demonstrate all systems and address any questions.
