New construction & tenant build-outs.

Ground-up commercial wiring and tenant improvements across Texas—self-performed from underground rough-in through final inspection by the electrical arm of a commercial construction group.

Overview

One electrical contractor for the whole build.

Pillars Electric self-performs the full electrical scope on commercial new construction and tenant build-outs across Texas. We’re not a general-purpose shop bidding the work—we’re the electrical arm of a commercial construction group, which means we read the full set of drawings, sit in the coordination meetings, and own the schedule the way a serious project demands.

From underground rough-in on a ground-up building to a single-tenant interior fit-out, the same crew runs the job from first conduit to final inspection. The work covers raceway and feeder installation, branch wiring, lighting and controls, fire-alarm and low-voltage coordination, temporary power, and closeout—sequenced around the GC’s schedule and every other trade on site.

The standard never changes: code-compliant, inspection-ready, on schedule. Same crews, no markup layers, no surprises at the inspector’s walk-through.

What’s Included

The scope, end to end.

01

Underground & slab rough-in

Site service feeders, underground conduit runs, slab penetrations, and below-grade boxes set before the pour—coordinated with civil and structural.

02

Service & panel/feeder installation

Utility coordination, service entrance, switchboards and panels, feeder pulls, and grounding sized to the engineered load.

03

Branch wiring & devices

Receptacles, switches, dedicated circuits, equipment connections, and device trim—wired clean, labeled, and ready for trim-out.

04

Lighting & controls

Interior and exterior lighting, occupancy and daylight controls, dimming, emergency egress, and energy-code compliance built in from layout.

05

Fire-alarm & low-voltage coordination

Pathway, power, and rough-in coordination for fire alarm, data, security, and AV—so the low-voltage trades drop into a clean infrastructure.

06

Tenant-improvement fit-outs

Demising-wall rewires, new device layouts, lighting reworks, kitchen and equipment power, and landlord-spec turnover for retail, office, and medical TIs.

07

Temporary power

Job-site temp service, distribution, and lighting—sized for the build, maintained through the schedule, and torn out clean.

08

Inspections & closeout

Permit pulls, rough and final inspections managed with the AHJ, as-built markups, panel schedules, and the closeout package owners actually need.

How We Approach It

Built around the schedule, not on top of it.

We read the full set. Not just the E sheets—civil, structural, architectural, mechanical, plumbing, fire protection. Electrical touches everything, and decisions made on the architectural set drive what we’re doing underground three weeks before slab. We catch the conflicts at the table, not at the trench.

We coordinate with the GC and every trade. Because we’re the electrical division of a construction group, the way the build sequences is in our DNA. We know when framing needs its rough-in complete, when mechanical needs its disconnects, when the inspector likes to see the panel schedule. That coordination shows up as fewer RFIs, fewer change orders, and a schedule that holds.

We sequence around the build. Rough-in waits on the right walls. Trim-out waits on the right ceilings. Temporary power moves with the work. Long-lead gear is ordered the day the submittal is approved—not the day someone notices it’s missing.

We manage inspections proactively. Permit pulled, rough scheduled at the right phase, final walked clean. The AHJ relationship matters; we don’t treat the inspector as the last surprise of the job.

What It Depends On

Cost and scope drivers.

Square footage

Total conditioned area sets device counts, feeder lengths, and crew loading more than any other single factor.

Service size

Amperage, voltage, and whether utility service is upsized or new drives gear cost, lead time, and coordination.

Finish level

Class-A office vs. warehouse shell vs. medical or kitchen build-out changes device density, controls, and trim spec dramatically.

Schedule

How tightly the build is sequenced—and whether the project demands phased turnover—shapes crew size and overtime.

Occupied vs. vacant

Working in an occupied building means after-hours cutovers, infection control or noise constraints, and tighter coordination with operations.

Questions

What owners and GCs ask.

Do you bid plan-and-spec build-outs for general contractors?+
Yes. We price plan-and-spec commercial scopes for GCs and developers across Texas. Send drawings and specs through the contact form and we'll review and follow up quickly.
Do you self-perform the work or sub it out?+
We self-perform with our own crews from underground rough-in through final inspection. The same team that starts the job finishes it—consistent quality, no markup layers.
Do you handle the permit and inspections?+
Yes. We pull the electrical permit, coordinate rough and final inspections with the AHJ, and manage closeout documentation. Our standard is code-compliant, inspection-ready, on schedule.
What size commercial build-outs do you take?+
From single-tenant interior fit-outs up to ground-up commercial and industrial buildings—over a million square feet powered and 5,000+ units wired across multifamily, warehouse, retail, and industrial.
