The SLAC National Accelerator Laboratory outlines its comprehensive evaluation factors for awarding contracts in this document. This best-value trade-off source selection prioritizes an integrated assessment of technical factors, subfactors, and cost/price. SLAC aims to award contracts to offerors demonstrating the greatest confidence in meeting or exceeding requirements, potentially selecting higher-rated, higher-priced proposals if technical superiority outweighs cost differences. The evaluation process is subjective, relying on professional judgment. SLAC intends to award a single contract and may reject unrealistic offers or eliminate proposals with uncorrectable deficiencies. Proposals will be evaluated on technical factors (Past Performance, Safety, Technical Approach, Schedule) and business factors (Financial Standing, Price, Terms and Conditions Acceptance). Technical proposals are rated on an adjectival scale (Exceeds, Meets, Does Not Meet Requirements), while business proposals are assessed for completeness, realism, and reasonableness. Debriefings are available upon request to explain selection decisions without comparing proposals.
