What Belongs in the Low-Voltage Scope on Your Bid

Low-voltage is rarely one line on a bid. It is usually several, split across several subs, and the space between them is where a job gets expensive.

An electrical contractor coordinating four low-voltage subs is not managing four scopes. They are managing four scopes plus every seam between them, and the seams are not on anyone's bid.

The Scope Is Wider Than Most Bids Reflect

A full low-voltage package covers more than cabling:

• Structured cabling and connectivity: data cabling, fiber backbone, WiFi, intercom
• Access control: badging, burglar and intrusion alarms
• Video surveillance: cameras and monitoring
• Fire and life safety: fire alarm, area of refuge, ERRCS
• Smart building systems: wireless door locks, lighting and thermostat control
• Design and consulting: buildable design and value engineering
  
  

Split across separate subs, each of those is bid to its own drawing set. Nobody is bidding the space between them.

Gaps Open at the Seams, Not in the Middle

The systems themselves are rarely the problem. The handoffs are.

Pathway and conduit responsibility. Equipment room space and rack allocation. Power coordination for devices someone else is installing. Head-end integration between access control, surveillance, and fire. Terminations at the boundary between two subs' scopes.

Each of those sits between two bids. When neither sub owns it, it surfaces during rough-in, and by then the schedule is already tight.

The Gaps That Turn Into Change Orders

Some are minor. A few are predictable and expensive.

Fire and life safety systems carry code requirements that get discovered late, particularly ERRCS and area of refuge, which are commonly missed at bid time and difficult to add cheaply afterward.

Pathways sized before the full device count is known force either congested conduit or new pathway. Equipment space allocated for one system rarely accommodates three. Integration between systems bid separately often assumes coordination nobody scoped.

None of these are field errors. They are bid-stage omissions that surface in the field.

Questions Worth Asking Before You Submit

• Which systems are in this scope, and which are excluded?
• Who owns pathway, conduit, and equipment room space?
• Who is responsible for integration between systems?
• What has to be coordinated with other trades, and when?
• What is assumed rather than drawn?

One Scope, One Point of Accountability

WireTech handles the full low-voltage scope under one roof, which removes the seams rather than managing them. One partner, one bid, one point of accountability through closeout and after.

We are brand-agnostic, so the recommendation fits the project rather than a manufacturer's incentives. Fifteen years in business, with NICET and BICSI certified staff. We prefer to be involved early, where scope gaps and design problems can be caught before they become change orders.
