Construction Contracts and Purchase Agreements
Published in Rebecca Mirsky, John Schaufelberger, Professional Ethics for the Construction Industry, 2022
Rebecca Mirsky, John Schaufelberger
Both general contractors and subcontractors purchase construction materials from suppliers by means of purchase orders or agreements. The contractors and subcontractors provide the contract specifications to the supplier to enable the supplier to determine which products meet the specification requirements and provide the information to the general contractors and subcontractors. If the contract stipulates that the material must be approved by the project designer, the contractor must provide a submittal that either contains a sample of the material or manufacturer’s information demonstrating conformance with the contract specifications. Once the material has been approved by the project designer, the contractor or subcontractor determines the quantity required and issue a purchase order to the supplier requesting the cost for the approved materials. The contractor or subcontractor then approves the purchase agreement ordering the required materials. A purchase agreement basically is a supply contract for the acquisition of construction materials.

A submittal is a document or product turned in by the construction team to verify that what they plan to purchase, fabricate, deliver, and ultimately install is in fact what the design team intended by their drawings and specifications. It serves as one last check and validity of design. Submittal requirements for a project are contained in the specifications of the contract. Project managers should look upon submittals as a first step in quality control and, therefore, as a tool to be used to complete a successful project. The procedures for processing submittals generally are in Divisions 00 and 01 of the contract specifications. Section 00-72-00.4.03 of the specifications contains submittal procedures for the NanoEngineering Building. This section of the special conditions contains specific instructions regarding submittal preparation, copies to be provided, and the review process.
Project documentation

Submittals are a continuation of the design process by the construction team, at least through the early to middle phases of the construction control and execution phase. Submittals provide additional detail to the contract drawings and specifications, which provide the designer and owner with assurance that the GC, subcontractors, and suppliers will all be providing and installing the correct materials. Submittals take on a variety of formats, including shop drawings, mock-ups, cut sheets, and physical samples. In addition to validating the design intent, submittals are an early form of quality control and schedule assurance. Project engineers play a major role in RFI and submittal coordination and the corresponding log maintenance.
Disruptive information exchange requirements in construction projects: perception and response patterns

The construction submittal routine for project parties entailed aggregating the documentation needed for design and construction, and then transmitting the submittals to an upstream project party for review and approval. For example, vendors would provide cut sheets and samples to subcontractors; subcontractors would prepare submittals for the GC; and the GC would transmit submittals for architect, engineer and owner review. After receiving approvals for and completing the work, each party was required to update and re-transmit the submittals (as well as operations and maintenance documentation) to the upstream party for project close-out (see Figure 1).
