Singapore Changi International Airport People Mover System

Lea+Elliott was selected as part of a multi-disciplinary Master Plan team to address all aspects of the intra- and inter-terminal automated people mover (APM) system necessary for the planning and conceptual design of Terminal 3. The firm's responsibilities included development of an effective plan for the inter-terminal people mover system at Terminal 3, as well as integration with existing Terminals 1 and 2, and provisions for future expansions and connection to a new Terminal 4 complex. The alignment, operational strategy, phasing, schedule, and estimated system costs were developed as a part of the overall conceptual plan. Lea+Elliott was subsequently selected by Civil Aviation Authority of Singapore (CAAS) in a competitive process to be its PMS/APM consultant.

This work included a full analysis of the PMS/APM requirements due to significant changes in Terminal 3 configurations and uses. This detailed planning phase included existing ridership for several future airport use scenarios, developing and analyzing alignment and station alternatives, simulating train operations and estimating capital and O&M costs. The proprietary Lea+Elliott LEGENDS© models were used for these analyses. We also developed basic requirements and designs for stations and maintenance facilities.

Lea+Elliott developed the Tender Documents in conjunction with CAAS. Our primary responsibilities were: the Special Provisions, Technical Provisions (Performance Specifications), Operating and Maintenance Provisions, Reference Drawings, review of the Instructions to Tenderers Submittal Requests, and the development of the Pricing Forms and Tender evaluation procedures. Lea+Elliott also led the Tender evaluation process. The Tender was closed in May 2001 and three Tenderers were evaluated. Our recommendations were then forwarded to CAAS.

Subsequent to our Tender evaluation, and in an effort to reduce the PMS project costs, CAAS decided to alter the System configuration, as well as fleet and operational requirements. This necessitated a second Stage Tender process. CAAS did not add monies or scope to our contract and therefore modified the Tender documents, and then evaluated the re-submitted Tender offers.

The Phase 3 - Construction Monitoring - portion of our contract with the issuance by CAAS of a Letter of Acceptance to the selected supplier, Mitsubishi Consortium (Mitsubishi Corporation and Mitsubishi Heavy Industries). Our primary responsibilities for Phase 3 were to monitor the implementation of the PMS project with regard to submittal reviews, value analysis, contractor oversight, on-site quality review, factory tests and inspections, on-site testing, and system commissioning.
