The guiding principle of contract law is that a contract will be interpreted to give effect to the intention of the parties.  To discern that intention, a court will look first to the written document, the so-called "four corners rule" of contract interpretation.  If that document is ambiguous -- that is, susceptible to more than one interpretation -- the court can look outside the four corners to "extrinsic evidence."  Extrinsic evidence can include other documents, testimony of the parties as to their intent in entering into the contract, called "parole evidence," or the way the parties actually conduct themselves under the contract, particularly before a dispute arises.

Another principle of contract interpretation, not always applied with consistency, is that an ambiguous contract will be construed against the interests of the party who drafted the contract.  This means that if a party is given a contract on a take it or leave it basis with no opportunity to fairly negotiate the contract language, and the contract is susceptible to more than one interpretation in some respect, an ambiguous provision will be construed in favor of the non-drafting party.  Also, a court will always try to harmonize all parts of the contract so that if a clause is ambiguous and one interpretation of the clause creates a conflict with another non-ambiguous clause, the non-conflicting interpretation will prevail.

It is important to understand that a contract is not necessarily a static document, even where the parties don't sign any addenda or modifications.  This is because the parties can inadvertently choose one interpretation of an ambiguous provision merely by acting consistently with that interpretation, particularly before a dispute arises.  For example, if a notice requirement in a change clause is not clear, but the parties proceed on the project processing changes with no formal notice, the notice requirement will be dispensed with by a court based upon the way the parties acted.  That is, their conduct is regarded as dispositive of the parties' intentions as to the ambiguous notice provision.

It is also important to recognize that the parties can amend their contract by their very conduct even though they had no discussions about the modification and signed no addenda, and even though the contract has a requirement that any modification of the contract be in writing and signed by both parties.  In Hahl v. Langfur Const. Corp., 529 P.2d 1369, (Colo. App. 1974), the operative contract had a written change order requirement.  A dispute arose as to the validity of the subcontractor's claim for additional work,  and the general contractor defended on the grounds that the work had been performed without prior written authorization.  The Colorado Court of Appeals held that the parties had amended their contract and waived the requirement for written authorization by their words and their conduct.  Accord, Hi-Valley Constructors, Inc. v. Heyser, 428 P.2d 354 (Colo. 1967) (by their conduct, parties waived contract requirement for written authorization).

Construction Contracts 101 – The Basics

Virtually all construction projects are accomplished by way of a contract of some sort, and it is important to keep basic contract law in mind when drafting, negotiating, reviewing and entering into construction contracts.  To be enforceable, a contract must be supported by consideration.  In its simplest form, consideration is a promise – a contract thus is a promise given in exchange, that is in consideration, for a promise received.  A contract does not necessarily need to be in writing; the conduct of the parties can rise to an enforceable oral contract.

In a construction setting, a contractor agrees, promises, to build a structure in exchange for the owner’s promise to pay for the construction.  Of course, the complexities of a construction project require that there be many promises given and received.  These promises create rights and obligations on both sides that are expressed in the written contract language.  However, the effect of a contract doesn’t end there, as there are often obligations that are attendant to a written contract implied by law.  For example, every contract in Colorado contains an implied duty of good faith and fair dealing.  Wells Fargo Realty Advisors Funding, Inc. v. Uioli, Inc., 872 P.2d 1359, 1362 (Colo. App. 1994).  The doctrine exists to effectuate the parties' intentions and to honor their reasonable expectations.  City of Golden v. Parker, 138 P.3d 285, 292 (Colo.2006); Amoco Oil Co. v. Ervin, 908 P.2d 493, 498 (Colo. 1995) (Good faith performance of a contract involves “faithfulness to an agreed common purpose and consistency with the justified expectations of the other party.”).

While it is unlikely that anyone can draft a truly "impenetrable contract," it is possible to craft a relatively clear and consistent document that is not susceptible, at least on its face, to multiple interpretations giving rise to the possibility of a dispute over contract meaning.  To do so, it is helpful to understand some of the basic rules of contract construction that a judge, or an arbitrator, will use in trying to decide a claim.
