Construction contract documents are written documents that define roles, responsibilities and “work” in the construction contract and are legally binding on the parties (owners and contractors). The individual documents that make up the building documents are defined in the owner-contracting contract (in the CDC® C-520 (2013) (in both the AEPC and AIA standard documents). A subcontract is primarily a contract between a contractor or a prime contractor and a subcontractor. It describes the limitations of specialized work to be done for the construction project.  A “basic date” is a reference date from which changes in conditions can be assessed. In a work market, the inclusion of a base date is generally used as a mechanism for the distribution of risk between the owner and the contractor for changes that could occur between the contractor`s pricing of the offer and the signing of the contract. This can be a very long time and the changes that occur can have a significant impact on the cost of the work.  The terms of the contract define the most important legal relationship between the parties to a construction project and determine the distribution of risk and hence the price. A national construction contract is a contract that includes all work that should be done for the construction of a purchase or dwelling building existing or taking place in a given country; not foreign or international.
A court may consider other construction or interpretation canons if it finds that the contractual terms are ambiguous. In commercial situations, the court may take into account business developments or performance, i.e. the behaviour observed in previous transactions between the parties. Such evidence may assist the court in determining the intent of the parties at the time of the contract and provide additional conditions that the court, although not expressly included in the agreement, may use to interpret the contract. Therefore, where one party asserts that the other party breached the contract by not making the payment properly and the contract does not contain explicit payment provisions, the Tribunal may consider how the parties end the issue of payment in previous transactions in order to resolve the issue (AROK Construction Co./Indian Construction Services, 174, ariz. 291 , 848 S.2d 870 [Ariz. Circa 1993). As in the legal construction, in a contractual dispute, the court gives the terms of the contract its clear and ordinary meaning and interprets them as ordinary, average or reasonable persons who would understand them (Rains v. Becton, Dickinson – Co., 246 Pages 746, 523 N.W.2d 506 [Neb. 1994]). If the language of the contract is clear and unambiguous, there is no room for a broader interpretation and the court will apply the contract in its written version.
In doing so, the Tribunal intends the parties to enter into the contract and avoids adding an interpretation of its own to the agreement. A construction contract can be declared as a guarantee that the contract executed receives the specific amount of compensation or the manner in which the remuneration is distributed. In addition, a work contract is negotiated specifically for the construction of an asset or group of related assets. Lump-sum contracts, also known as fixed-rate contracts, are the most fundamental type of construction contracts. This is because they draw up a fixed price for all the work done between them. This is why contract contracts are very common in the construction sector. In the past, most contractors have entered into several lump sum contracts.
