Some of the limitations of this process include the following: · The vendors and contractors do not have opportunities to offer any ideas they may have on how to improve the product or process. · The steps are sequential and, therefore, take a fairly fixed, typical amount of time. · System integration is the responsibility of the owner. · Coordination during construction among the independent low bidders can be difficult. " · Total costs are not known until all contracts are awarded. 2.1.5.2 Limited Turnkey This procurement alternative is similar to the conventional industry practice, except that a single vendor is selected for the systems element. This is different from "sole-source" in that the contract is awarded pursuant to competitive bids. The contractor, however, assumes total control and responsibility for vehicles, trackwork, signals and communications, the control facility, and all other equipment necessary to make the system work. The systems element of a fixed guideway transit project generally requires the most integration; limited turnkey places that integration responsibility with a single vendor. The systems element may be procured by using this alternative with a performance specification. All environmental clearances, design and construction of the civil infrastructure, and system operation remain the responsibility of the public agency-owner. 2.1.5.3 Design-Build This "turnkey" alternative addresses the system integration issue and presents the opportunity for the vendors and contractors to provide input to the design process. The approach consists of the following: A single contractor (design-build team) is selected to implement the project after Preliminary Engineering, environmental clearance, and a "clean" right-of-way is available. All coordination and systems integration is the responsibility of the design-build contractor. Any cost overruns due to design error or technology/system integration are the design-build contractor's responsibility. The design-build contractor completes final design consistent with the Preliminary Engineering definition of the project (typically 30% design level). This provides the design-build contractor with the opportunity to incorporate innovative ideas in the final design. Such a process may result in more efficient techniques during construction, comparable improvements at cost savings, and a fast-tracked implementation schedule.
