ATSER was selected to perform Quality Assurance services on METRO’s Quality Program for its $5 billion, Phase II. At the time, METRO was considering traditional Design‐Bid‐Build (DBB) and alternative delivery methods such as Design‐Build (DB), Design‐Build including Operate and Maintain (DBOM), and Finance with Design‐Build including Operate and Maintain (FDBOM). After submitting a White Paper describing the various delivery methods and their advantages and disadvantages, ATSER was contracted to develop METRO’s Quality Master Plan (QMP), which received FTA approval, and a detailed Quality Assurance Requirements (QAR) document outlining the requirements of the Quality Assurance Plans (QAP).
