A practical guide to reading construction specifications for bid teams that need to understand scope, products, execution, submittals, quality, and addenda.

Reading Construction Specifications for Bidding

Construction specifications explain requirements that drawings may not show fully. Estimators should read specifications and drawings together so scope, products, quality, execution, and closeout requirements are not missed.

Specs are part of the bid documents, not background material.

Record questions and assumptions before pricing.
