California project estimating
Electrical Estimating Services in California
An electrical bid for a California tenant improvement needs more than a fixture count. F&K prepares electrical quantities that connect lighting layouts, control schedules, power plans and the specified acceptance-testing scope. Share the permit-stage drawings and energy documents so the estimate reflects the selected design rather than a generic electrical allowance per square foot.

Make lighting controls visible in the bid
California’s Energy Commission publishes separate compliance, installation and acceptance documentation for nonresidential lighting and electrical systems. The 2025 Energy Code applies based on the permit-application timing described by the Commission. Identify the applicable project edition before estimating. A room with luminaires may also require scheduled sensors, dimming devices, control wiring and programming that a fixture-only takeoff would miss.
For an alteration, separate existing equipment to remain from relocated devices and new installations. The energy scope and issued design determine which areas are affected. Do not extend one room’s control arrangement across an entire building without checking the schedules. California school work, healthcare facilities and ordinary tenant spaces may also have different reviewing authorities, so name the project jurisdiction and facility type in the request.
What the takeoff can include
Room-by-room controls
Associate occupancy sensors, daylight-responsive devices and switching with each room’s control sequence. Record device types and controlled zones.
Fixture package
Group luminaires by schedule type, mounting and emergency function. Keep owner-selected decorative fixtures distinct from contractor-supplied assemblies.
Power and distribution
Measure circuits, feeders, panels and disconnects from the power drawings. Track equipment connections and changes caused by the proposed mechanical systems.
Acceptance and commissioning
Identify the specified testing, documentation, programming and training responsibilities. Treat outside technician quotations as separate inputs where required.
Measurement and scope checks
The working check is a room-to-system crosswalk: lighting type, control zone, device count and drawing reference. We compare it with the electrical schedule and energy documentation before preparing totals. If the sequence calls for a function with no corresponding device on the plan, that becomes a clarification item. The priced version can then distinguish supply, installation, programming and acceptance-testing allowances for the contractor’s review.
Illustrative control-device comparison
For a hypothetical tenant space, the room schedule identifies three separately controlled rooms. These quantities explain a reconciliation method, not a code-compliance design.
| Space | Specified arrangement | Count to track |
|---|---|---|
| Two meeting rooms | One sensor and one dimmer in each | 2 sensors + 2 dimmers |
| Open office | Three control zones, one sensor per zone | 3 sensors |
| Package total | Before control panels or cabling | 5 sensors + 2 dimmers |
The controls narrative may require additional gateways, relays or interfaces. Acceptance tests and programming are separate scope items, even when the hardware counts are correct.
Deliverable, pricing basis and quote
Request an electrical workbook split between new work, relocated work and retained systems, with device schedules and exclusions attached. For budget comparisons, keep lighting alternates and owner-supplied fixtures outside the base total. A takeoff does not certify California energy compliance. The quote confirms whether pricing, revisions and drawing markups are included and identifies the required delivery date before measurement begins.

Does the estimate include California acceptance testing?
Only when the agreed scope includes it. The workbook can identify the relevant testing package and carry a supplied quotation or stated allowance. Completion and certification by the required technician are separate from estimating.
Can you estimate an occupied tenant improvement?
Yes, identify occupancy, shutdown windows, temporary power and phased handover requirements. These affect installation planning and pricing assumptions even when the final device quantities are unchanged.
Should I send the energy forms with the electrical drawings?
Yes. They help reconcile lighting controls and other specified features with the plan set. If the documents conflict, the design team should clarify the requirement before an allowance is presented as final scope.
