Scope: what is in and what is out
The most common bid disputes come from scope gaps. A good proposal states clearly what is included and what is not, and references the drawings and addenda it was priced from.
- Drawing sheets and revision or addendum numbers used for pricing
- Wall types and partition schedule covered
- Board type and thickness, including rated and moisture-resistant areas
- Finish level by area, such as Level 4 or Level 5
- Ceilings: acoustical grid and tile, hard-lid, soffits and bulkheads
- Exclusions, such as paint, insulation, blocking by others, patching after other trades or high-pressure work
Price, terms and schedule
The general contractor also needs numbers and terms that can be dropped into a bid comparison.
- Lump sum price with clear breakdown by area or scope
- Unit prices for additions and deductions
- Alternates listed separately
- Proposal validity period and any material price assumptions
- Expected duration and the earliest start date
- Payment terms and how change orders will be handled
Paperwork GCs usually ask for
Most general contractors want to see a current license, a certificate of insurance showing general liability and workers compensation, and a W-9 before a subcontract is issued. Having these ready shortens the path from bid to contract.
Clarifications help everyone
If the drawings conflict, finish notes are missing or the schedule looks unrealistic, a good subcontractor says so before the contract is signed. Asking a question during bidding is cheaper than absorbing a change later.

Should a sub bid lump sum or by unit price?
Most general contractors want a lump sum for the defined scope, plus unit prices for additions and deductions so changes are easy to price.
What documents should come with a bid?
A current license, a certificate of insurance and a W-9 are the usual documents, along with the proposal itself.
Do you review plans before bidding?
Yes. We review the drawings, flag conflicts and return a written estimate.
