11 Procurement process

Procurement is the process of selecting firms to perform the work described in the tender documents. Usually the size and/or the officialdom of the project determine which procurement path is to be taken. A common feature of procurement procedures is that they all require the preparation of tender documents.
Tendering is the activity which eventually determines the three factors of principal interest to the client: cost, quality and time.

The tender documents are a set of documents which enable the tendering contractors to price the work and submit an offer to complete the specified items. The composition of the documents can vary, depending on the scale or the officialdom of the project, but usually include bills of quantities (BoQ), specifications and drawings.

• Bills of quantities (BoQ) are sets of descriptions defining the quantity and quality of construction work. They provide the contractor with sufficient information to tender for the work efficiently and accurately.
• Specifications contain descriptive information of the project in writing. In contrast to BoQs, they do not contain any measurements.
• Drawings give the tenderer the opportunity to visualise the scale and shape of the building.
