Engineering and Construction

Invitational bidding, also called   closed bidding , is another variation of the DBB method that is generally used for quasi-public and some private projects. In this method, the owner preselects general contractors who have demonstrated, based on their experience, resources, and financial standing, their qualifications to perform the work. The selected contractors are then invited to bid for the project, and the contractor with the lowest bid is then awarded the contract. The architect (as the owner’s representative) may be involved in the prescreening process.
