Competitive open-shop market ($38-$62/hr) alongside IBEW Local 569 on defense, biotech, and public works.
📝 Estimator's Field Note
"The most common scope gap I find in plan reviews is the coordination between the electrical contractor's work and the low-voltage systems. When the data, security, and AV systems are designed by separate consultants, there are almost always overlaps or gaps in the raceway and power requirements."
🔍 Scope Gap Warning
Outdoor lighting and landscape power scope is often split between the electrician and the landscape contractor, creating a coordination gap. We flag this on every residential estimate.

📦 Coordination Note from Our Team
Low-voltage and AV rough-in needs to be coordinated with framing. The structured cabling panel location, media room conduit, and security keypad backboxes all need framing modifications that the framer needs to know about before they start.
