In order to identify the largest scale transportation <br /> improvements,we will provide a broad-brush assessment of projects to identify likely capital costs <br /> as low, medium or high. <br /> Develop Cost Estimates (Optional) <br /> Optionally, more detailed cost estimates could be developed as part of this task if desired at this <br /> stage. The Fehr & Peers team could develop Opinions of Probable Construction Costs for up to <br /> 20 projects identified in Task G.2. For specific projects, quantities will be derived for major cost <br /> items including roadway paving materials, sidewalks, bridge structures, retailing walls, and traffic <br /> signals and modifications. For general treatments,quantities will be estimated on a per unit length <br /> basis, or for a typical application that could be installed at several locations. <br /> Unit prices for these items will be determined based on bid results from recent projects in <br /> Redwood City and the most recent Caltrans Contract Cost Data Book. Costs for items such as <br /> demolition, drainage improvements, maintenance of traffic, utility relocations, mobilization, and <br /> clearing and grading would be based on a percentage of the other construction costs. To this, <br /> contingencies will be added for undeveloped or unknown project elements and risks to determine <br /> a total construction cost. Soft costs, including design engineering, design services during <br /> construction, and construction management will be based on the total construction costs as a <br /> percentage. <br /> Assumptions: <br /> • Opinions of Probable Construction Costs will be a level of detail consistent with the design <br /> development with the projects <br /> • The City of Redwood City will provide all recent project bid results to Fehr& Peers team <br /> The number of projects are based on a minimum level of complexity.If significantly complex project <br /> evaluation is required, the level of effort would be equivalent to several 'minimally complex <br /> projects'. <br /> Optional Deliverable: Opinion of Probable Construction Costs for 20 minimally complex <br /> projects <br />
