Indiana Electrical Code (project-specified electrical code with 675 IAC 17-1.8). State Fire Marshal and local municipality plan review.
Indiana electrical construction operates under the Indiana Electrical Code (project-specified electrical code with Indiana Amendments 675 IAC 17-1.8) overseen by the Fire Prevention and Building Safety Commission. Indianapolis, Fort Wayne, and the Northwest Indiana region (near Chicago) are seeing major capital investment in pharmaceutical campuses (Eli Lilly), automotive manufacturing, and distribution centers along I-65 and I-70. Project inquiries can cover reliable, highly accurate takeoffs that win competitive bids.
Pricing is determined by project scope, complexity, documentation, and required deliverables. Request a project-specific quotation.
📝 Scope Review Consideration
Compare the issued drawings with specifications and equipment schedules. Record conflicting requirements as requests for clarification and agree their treatment before pricing.
🔍 Scope Gap Warning
Watch for the fire alarm and security systems scope gap. Many commercial plans show fire alarm on the electrical drawings but reference separate specifications that the electrical contractor may or may not be carrying.

📦 Estimating Coordination Note
Coordinate with the GC on the electrical room rough-in sequence. The concrete floor in the electrical room should be poured and cured before switchgear delivery, but the conduits entering the slab need to be stubbed up before the pour.
