On most commercial construction and tenant improvement projects, the electrical scope is not what blows the schedule. What blows the schedule is when the electrical scope gets defined — typically after the layout is fixed, after the equipment is ordered, and after the ceiling grid has been coordinated around everything except the conduit.
Commercial electrical construction is one of the earliest scopes that needs decisions and one of the last that can finish. That asymmetry is where cost and delay come from.
Decisions That Have to Happen Early
The equipment list
Every piece of equipment that will plug in, hardwire, or connect to the building drives electrical design: kitchen equipment, medical and dental equipment, machine tools, compressors, server and network gear, HVAC, specialty process loads. Voltage, phase, connected load, and physical location for each.
The single most common driver of electrical change orders is an equipment list that arrives after rough-in. Circuits already run, conduit already placed, and now the three-phase equipment someone just specified needs a feeder from a panel forty feet away.
Service and distribution capacity
Does the existing service support the intended use? For a build-out in an existing building, this question deserves an answer in week one. A shell built for general office and leased to a restaurant, a medical practice, or a light manufacturer is a different electrical project than the landlord assumed.
Long-lead equipment
Switchgear, panelboards, transformers, and generators have carried extended lead times, and in many cases they still gate project schedules. Establish actual lead times with your contractor early and order against the schedule rather than the design completion date. This is now a scheduling input, not a procurement detail.
Coordination With Other Trades
Above the ceiling, everything competes for the same space: ductwork, sprinkler mains, plumbing, structure, cable tray, and conduit. Ductwork and sprinkler generally have less routing flexibility than conduit, which means electrical routes around them — and that routing needs to be coordinated on paper rather than resolved by whoever gets there first.
The same applies to walls. Panel locations, required working clearances per NEC 110.26, device locations relative to casework and furniture, and floor box locations relative to final layout all need to be confirmed before rough-in. Moving a floor box after the slab is poured is a different project than moving it on a drawing.
Systems That Get Designed Late and Cost More For It
- Lighting design and layout and lighting controls — driven by finish layout, ceiling type, and how the space will actually be used
- Fire alarm and life safety — governed by code and inspection, with little flexibility once the layout is set
- Low voltage, data, and AV — pathway needs to be planned with the electrical rough-in, not after drywall
- Access control and security — needs power and pathway at every controlled opening
- Automation and control systems — integration points affect device selection across multiple trades
- Standby power and grounding and surge protection for sensitive equipment
Each of these is inexpensive to accommodate during design and expensive to add after walls are closed.
A Realistic Sequence
- Program and equipment definition. What goes in the space and what it needs electrically.
- Load calculation and service verification. Confirm capacity before committing to the layout.
- Design and drawings. Coordinated with mechanical, plumbing, and structural.
- Permit submission. Timeline varies by jurisdiction across the Metroplex; build it into the schedule.
- Long-lead procurement. Ordered against schedule need dates.
- Rough-in. Conduit, boxes, feeders, and pathway before the walls close.
- Rough inspection. Scheduled with real buffer, because a failed inspection stops drywall.
- Trim and finish. Devices, fixtures, panel labeling, terminations.
- Final inspection, commissioning, and closeout. Including as-builts and control system training.
What Belongs in Closeout
Closeout documentation is what the building owner lives with for the next twenty years, and it is routinely the weakest deliverable on a project.
- Accurate as-built drawings reflecting what was actually installed
- Complete and correct panel schedules — not the design-phase version
- Equipment cut sheets, O&M manuals, and warranty documentation
- Control system programming documentation and credentials
- Test and inspection records
- A recommended preventive maintenance schedule for the installed systems
If the closeout package is thin, every future service call starts with an hour of investigation that somebody pays for.
Choosing a Commercial Electrical Contractor
For commercial electrical construction, the questions worth asking are about process rather than price: how the contractor handles coordination with other trades, how they manage long-lead procurement, who attends coordination meetings, how change orders are documented and approved, and what the closeout package includes. A bid that is low because it excludes coordination is not actually low.
Talk to Hargrove Electric
If you have a build-out or new construction project in planning, involving the electrical contractor during design costs less than involving them during rough-in. Hargrove Electric has served commercial and industrial clients across the Dallas–Fort Worth Metroplex for over 55 years, operating under Texas Electrical Contractor License #17522.
