# 636.201 What selection procedures and award criteria may be used?

You should consider using two-phase selection procedures for all design-build projects. However, if you do not believe two-phase selection procedures are appropriate for your project (based on the criteria in § 636.202), you may use a single phase selection procedure or the modified-design-build contracting method. The following procedures are available:

| Selection procedure | Criteria for using a selection procedure | Award criteria options |
| --- | --- | --- |
| (a) Two-Phase Selection Procedures (RFQ followed by RFP) | § 636.202 | Lowest price, Adjusted low-bid (price per quality point), meets criteria/low bid, weighted criteria process, fixed price/best design, best value. |
| (b) Single Phase (RFP) | Project not meeting the criteria in § 636.202 | All of the award criteria in item (a) of this table. |
| (c) Modified Design-Build (may be one or two phases) | Any project | Lowest price technically acceptable. |
