Common use of Preliminary Engineering Clause in Contracts

Preliminary Engineering. The Consultant is responsible for developing HST design concepts at a sufficient level of detail to develop accurate capital cost estimates, right-of-way requirements, construction staging, traffic and environmental impacts to satisfy CEQA and NEPA requirements. The design concepts will include: • Plan and Profile drawings of the alignment • Typical sections • Special structures and structural modifications • Electric Traction Facilities and Catenary • Right-of-way requirements • Construction Needs and Methods • Landscaping and amenities • Station layouts (including parking) • Renderings of proposed stations • Locations and functional layouts of support facilities (maintenance, storage, substations, etc.) • Utility relocation needs • Bridge reconstructions • Analysis of freight demands for the corridor • Impacts of proposed freight operations The Consultant will develop preliminary engineering (30%) design drawings of the HST alignments, stations and station sites, grade crossings, maintenance facilities, signal and electric power facilities, and bridges or other structures. Design drawings will be used to complete a 30% costs estimate. The Consultant will need to purchase and incorporate into the Work the appropriate aerial mapping for this task. The Consultant will develop HST cost estimates, documenting all project components. Costs should be presented in current year. Unit costs for systems elements (signaling, communications, and electrification) and HST vehicles will be provided by the PM. HST engineering design criteria, train systems (signaling, communications, and electrification) engineering, operational analysis and costs will be the responsibility of the PM. The design of Station will be the responsibility of the Consultant for the Regional Engineering/Environmental work. The Consultant will develop a staged construction plan for the project. This plan will identify operable project segments or elements of the HST infrastructure (such as grade separations) that could be constructed early and bring near term project benefits to existing rail freight and conventional passenger rail services.
