What Are the Contract Documents in Construction?

By Wyatt Cooper · Published · 3 min read

Key takeaways

  • The contract is not just the signed agreement: it is every document the agreement lists, read together.
  • Typically that is the agreement, general and supplementary conditions, drawings, specifications, addenda, and modifications issued after signing.
  • When documents conflict, the contract's order-of-precedence clause decides; on federal jobs, the specifications govern over the drawings.

The contract documents are the set of documents that together make up a construction contract: the signed agreement, the general and supplementary conditions, the drawings, the specifications, addenda issued before signing, and modifications such as change orders issued after. What the contractor must build is what these documents say, read together.

What is in the set

The usual contract documents and what each does
DocumentWhat it does
AgreementParties, price, contract time, and the list of the other documents
General conditionsRights and duties of owner, contractor and architect (AIA A201 is the common form)
Supplementary conditionsThis project's changes to the general conditions
DrawingsWhere things go, and how much
SpecificationsWhat quality, which products, how installed
AddendaChanges to the bid documents before signing
ModificationsChange orders, change directives and minor changes after signing

AIA describes its A201 general conditions as setting the rights, responsibilities and relationships of owner, contractor and architect, incorporated by reference into its owner–contractor agreements (AIA); the same page lists the agreements, such as A101 and A102. A map of them is in AIA contract documents explained.

Reading them together

The documents complement each other. In the federal clause, "anything mentioned in the specifications and not shown on the drawings, or shown on the drawings and not mentioned in the specifications, shall be of like effect as if shown or mentioned in both. In case of difference between drawings and specifications, the specifications shall govern" (FAR 52.236-21). Private contracts set their own order of precedence, so read it before you price.

Before signing, the set changes by addendum; after, by change order or change directive, or by an architect's minor change: see how to write an ASI. Questions about what the documents mean go by RFI. Shop drawings and submittals are not contract documents; they show how the contractor will meet them.

The bottom line

The contract documents are the whole set the agreement lists, and the work is what they say read together.

Keep one current set, with every addendum and modification logged, so the field builds from the same documents the price was based on. Join the waitlist to try Conflo.

Questions

Are the bid documents the same as the contract documents?

Mostly. The drawings, specifications and addenda carry over; the instructions to bidders and bid form usually do not, unless the agreement lists them.

Are submittals part of the contract documents?

Usually not. Under the common AIA approach, shop drawings and submittals show how the contractor proposes to meet the documents; they do not change them.
