Abstract:

Fifteen years of experience, observations and lessons gained by two of the leading turnkey contractors in the transit and large people mover market have led to the following conclusion: implementation of large line-haul transit and people mover projects using the Electrical and Mechanical (E & M) systems approach can result in definite advantages to clients and contractors as opposed to the multi-contracting, turnkey or super-turnkey approaches. In the E & M systems approach a single contractor is selected to provide most or all of the electrical and mechanical equipment for the project, including vehicles, train control, communications, power supply and distribution, trackwork, fare collection and other system-wide equipment. This approach can generate most of the benefits that turnkey or super-turnkey contracting provides when compared to multi-contract approaches, but at lower overall costs and without additional risks to the system owners. The E & M contractor can be selected at the 10% preliminary engineering stage and could participate in bringing the preliminary engineering to the 30% level. This will allow the civil contractors to bid to the same preliminary design, which has been completed to a much higher level of detail than is currently the practice on turnkey jobs, thus resulting in the lowest risk and most cost-effective solution.
