Subcontractor& the Sub Tier

Most of what gets built is built by subs. Each one answers to the GC, sees only its own subcontract, and carries the risk of its own trade.

Definition

A subcontractor is a specialty trade contractor hired by the general contractor, or construction manager, to perform a defined scope, electrical, mechanical, concrete, under a subcontract. Most of the physical work on a project is performed by subs, not by the GC itself.

One trade, one subcontract

The GC fans the project out to as many trades as the scope needs. Each subcontractor sees the box it was hired for, its own subcontract, its own schedule dates, its own scope, and nothing of the trades on either side of it.

What a sub carries vs what it does not

A subcontract is narrow by design, which is exactly what makes a specialty trade workable on a project with dozens of other trades.

A sub’s price is one line on the schedule of values, and once its subcontract is signed, that line becomes a committed cost on the GC’s budget.

How POD handles the sub’s view

POD gives a subcontractor their own scope, their subcontract with the GC and the work under it, not the whole project. On POD’s role-based access the Sub role is scoped to their contract, so a sub sees what they are accountable for and nothing of the other trades’ commercials.

Frequently asked questions

Its scope, its line, its risk

A subcontract is narrow on purpose. The sub owns its own trade; the GC owns the job of making every trade fit together.
