Ground-Up Reality

Small-to-Medium Commercial Ground-Up: What "New Construction" Actually Means

New construction electrical work is not modifying an existing shell. It's building the entire electrical infrastructure from the utility connection at the property line to the final receptacle in the finished space. Service equipment sized from scratch, meter set, main panel, grounding electrode system, branch circuits routed as framing is erected, and every trim device installed after drywall.

Hunterdon County doesn't see much large ground-up commercial (no big-box, no giant office parks). What HC does see is small-to-medium commercial ground-up: retail pad sites along Route 202 and Route 31, restaurant tear-down and rebuild along Routes 12 and 202, small standalone office buildings, medical practice buildings, and a real ongoing stream of vineyard tasting rooms, event barns, agricultural buildings, and mixed-use infill on Main Street corridors.

The reader here is usually a general contractor looking for an electrical sub, a property developer in early planning, or occasionally a small business owner building their own commercial location. Whichever role, the electrical scope requires early involvement, coordinated permit filing, JCP&L service application handled in parallel with construction start, and a clean trade sequence that keeps the project on schedule to CO.

Small-to-medium commercial fits our shop model well. We're not equipped to sub a 100,000 sq ft distribution facility, but retail pads, restaurants, small offices, medical buildings, and vineyard structures under roughly 15,000 sq ft are squarely in scope.

The Four Phases

The Four-Phase Commercial NC Electrical Timeline

Every ground-up commercial project follows the same broad electrical phases. Understanding the sequence and duration helps everyone coordinate parallel trades.

1

Planning & Design

4-8 weeks typical
  • Preliminary load calc per NEC Article 220
  • Service size and voltage decision
  • JCP&L service application submitted
  • Electrical drawings coordinated with GC/architect
  • Permit filing under N.J.A.C. 5:23
2

Site Prep & Foundation

2-4 weeks typical
  • Temporary power installation per NEC Article 590
  • Underground service conduit if applicable
  • Grounding electrode system installation
  • Site lighting and safety lighting rough coordination
  • JCP&L transformer coordination and easement
3

Framing & Rough-In

3-8 weeks typical

  • Branch circuit rough per NEC Article 300
  • Low-voltage rough (data, alarm, AV) coordinated
  • Rough inspection with township
4

Trim & Commissioning

2-4 weeks typical
  • Device install: receptacles, switches, fixtures

  • JCP&L final connection and meter set
  • Final inspection, CO coordination, walkthrough
JCP&L Coordination

Utility Coordination Runs Parallel to Everything Else

The JCP&L side of a new commercial service takes real time. Submitted too late, it becomes the schedule bottleneck. Submitted early and coordinated well, it stays out of the critical path.

Every new commercial connection needs a service application, load information, site plans, and often a transformer coordination or easement negotiation. Larger services (three-phase, higher amperage) sometimes require a pole line extension or a new pad-mount transformer.

We file the JCP&L application as part of Phase 1 and manage the back-and-forth through construction so the utility side is ready by the time we need meter set and final connection at Phase 4.

Code Framework

Commercial New Construction NEC Articles

The core NEC articles applied to ground-up commercial. Not exhaustive, but the primary framework.

Service & Load

Article 220 & 230

Article 220 governs load calculations for the service size. Article 230 covers services from utility to the service equipment. Together they define how big your main and how the utility feeder gets to it.

Grounding

Article 250

Article 250 covers grounding and bonding. Grounding electrode system installed early during foundation phase. Ground rings, ufer grounds, rod electrodes, and bonding of all metal building systems to a common ground.

Wiring Methods

Article 300

Article 300 covers general wiring methods and installation. Conduit fill, box fill, support requirements, spacing. Applies to every raceway and cable installed during rough-in.

Temp Power

Article 590

Article 590 governs temporary power installations for construction. GFCI protection required on temp receptacles. Applies from ground-breaking through Phase 3.

Emergency

Articles 700 & 701

Article 700 covers emergency power systems (life safety loads). Article 701 covers legally required standby systems. Coordinate with fire alarm and life safety consultants.

Special Occupancy

Articles 517 & 518

Article 517 for healthcare facilities. Article 518 for assembly occupancies (restaurants, event venues). Trigger additional receptacle placement, backup power, and egress lighting requirements.

What This Costs

An Honest Conversation About New Construction Cost

Ground-up commercial electrical is project-scale investment. The scope spans utility coordination, service equipment, all branch circuits, all devices and fixtures, low-voltage cabling, emergency systems, and final commissioning.

Every new construction quote is written and itemized against the drawing set. Line items typically break down by service equipment, feeders and subpanels, branch circuits by area, lighting and controls, low-voltage, and commissioning. This makes progress billing straightforward and lets everyone track scope changes cleanly.

Early involvement saves money. Getting the electrical scope figured out during Phase 1 (planning) rather than Phase 3 (rough-in) prevents change orders, redesign, and missed opportunities to right-size the service.

Common Questions

Frequently Asked Questions About Commercial New Construction Electrical

Depends on size and complexity. A small retail pad (under 3,000 sq ft) with simple service is typically 3-4 months total including permit lead time and JCP&L coordination. Medium builds (3,000-8,000 sq ft) run 4-6 months. Larger commercial (8,000+ sq ft) or complex occupancies (medical, restaurant with heavy kitchen loads) can run 6-9 months. We advise on realistic timing during initial project scoping.

As early as possible. Phase 1 (planning and design). Getting electrical involved during load calc, service sizing, and JCP&L application submission is the biggest single lever for keeping the project on schedule. Late involvement forces reactive decisions and often triggers change orders.

Yes, standard model for commercial new construction. We work as the electrical sub coordinated with the GC's overall schedule, permit sequencing, and trade sequence. Progress billing per contract terms. AIA G702/G703 or equivalent invoicing format available.

Filed during Phase 1 with load information and site plans. JCP&L site survey follows within a few weeks. Timeline from application to final connection varies significantly based on whether you need a new transformer, service upgrade, or overhead-to-underground work. Simple connections to existing poles can be quick. New pad-mount transformers can add several weeks. We manage the JCP&L back-and-forth through the project.

Yes. Temporary power per NEC Article 590 is standard scope on ground-up commercial. GFCI-protected temporary receptacles for framing crews, GC power tools, and lighting during interior work. Installed after site prep and removed at final connection.

Small-to-medium commercial. Retail pads, restaurants, small offices, medical buildings, vineyard structures, agricultural buildings, and mixed-use infill under roughly 15,000 sq ft are squarely in our wheelhouse. We are not equipped to sub a 100,000 sq ft distribution facility or heavy industrial.

Yes. Multi-month commercial NC projects are billed by phase completion or percentage complete based on contract terms. AIA G702/G703 format available. Cash flow works for both the GC and for us on longer projects.

Yes. On multi-tenant NC projects, base building electrical is designed with future tenant improvement scope in mind. Panel capacity headroom, subpanel provisioning per tenant space, low-voltage pathway planning. Makes the future TI work faster and cheaper for whoever leases the space.
