Bid Package

In Plain English

A set of documents sent to subcontractors describing exactly what work they need to price.

Definition

A bid package is a defined scope of work and associated documents issued to a specific trade or group of contractors for pricing. General contractors assemble bid packages to solicit subcontractor proposals for individual trades like electrical, mechanical, or concrete. Each bid package includes relevant drawings, specs, and scope clarifications.

Why It Matters in Bidding

Clear bid packages are how a GC controls scope coverage and avoids gaps or overlaps between trades, which is the single biggest source of post-award cost leakage. Well-drawn packages get more and better subcontractor coverage, sharpening pricing, while sloppy ones invite exclusions that the GC ends up absorbing.

Example

A GC's estimator splits the concrete work into a foundations package and a separate site-flatwork package, attaching only the relevant drawings, specs, and a scope letter to each so subs price exactly their portion without double-counting curbs or slabs.

Frequently Asked Questions

A solid package contains the relevant drawings and specification sections, a clear scope-of-work letter listing inclusions and exclusions, the bid form, schedule and phasing requirements, applicable addenda, and insurance or bonding terms. The scope letter is critical because it tells subs exactly where their work starts and stops.
Estimators map every spec division to a package and write explicit boundaries for shared items like blocking, backing, hoisting, and final connections. Reviewing adjacent packages together catches work that falls between trades, so no item is left unpriced or accidentally carried by two different subs.
Splitting work by trade lets specialized subcontractors price only what they perform, producing sharper, more competitive numbers and broader coverage per trade. It also lets the GC release packages on different timelines to match procurement lead times and the construction schedule rather than waiting on one combined bid.
