Main Contractor Procurement
Description
All construction and refurbishment projects require a main contractor to undertake the project. The Design Team, alongside the Quantity Surveyor will have produced design information and supporting cost plan information, this information is utilised to form the basis of the tender enquiries to the main contractors. The accuracy/quality of the design information and cost plan information is linked to the RIBA stage in which you commence procurement of the main contractor.
The Quantity Surveyor alongside the Project Team prepares the tender documents to enable the tender to be issued, the Category Manager will lead on the tendering/procurement process. The Procurement Plan for the project will determine the procurement and contracting strategy to procure the main contractor. There is a suite of tools and templates linked below that all Project Managers and Quantity Surveyors should refer to, prior to commencing the main contractor procurement process.
