Kimley»)Horn <br />Warner Avenue Street Improvements <br />1/10/2018 <br />Deliverables: 60%, 95%, and 100% Specifications, electronic files in PDF and word format (final <br />specifications will be sealed and signed), and responses to previous review comments from the <br />City <br />Task 17: Opinion of Probable Construction Cost <br />Kimley-Horn will prepare an Opinion of Probable Construction Costs (Estimate) based on <br />quantities, for comparison to project budget and assistance during the Contractor's bidding <br />process. Unit prices will be derived from readily available current bid information based on <br />similar projects within the area. Backup will be generated for lump sum items. Contingencies will <br />be shown, as agreed upon with City staff. <br />Deliverables: 30%, 60%, 95%, and 100% Estimates, electronic files in PDF <br />Task 18: Bid Phase <br />Kimley-Horn will provide services during the bid phase by responding in writing to requests for <br />information (RFI)/clarifications. Design changes, such as those for the contractor's preference, <br />are not included in this scope. Changes in the overall design concept are not accounted for in <br />this scope. This scope of work is based on hours provided on our fee schedule. Additional <br />construction support can be provided as needed on hourly rate basis. <br />Deliverables: Responses to three RFIs <br />Task 19: Storm Drain Design <br />Our team will provide a final design level hydraulic analysis to identify hydraulic grade line for <br />proposed storm drain main lines within the project area. Hydraulic grade line in downstream will <br />be provided by the City. Storm drain pipe sizing and discharges for the design of new storm <br />drain line will be obtained from City's storm drain master plan. Pipe sizing will be confirmed <br />through hydraulic analysis. We will look at options for designing a parallel storm drain main to <br />existing to be consistent with phase one design. Hydraulics analysis will be per Orange County <br />Local Drainage Manual requirements. Hydraulic analysis results will be used to prepare storm <br />drain plans for storm drain main line improvements on Warner Avenue between Oak Street and <br />Wright Street. Storm drain plans will be prepared at a scale of V = 20' horizontal and 1" = 2' <br />vertical for profiles. <br />Deliverables: 60%, 95%, and 100% Plans, electronic files in Microstation V81 and PDF, and <br />responses to previous review comments from the City <br />Task 20: Sound Wall Design <br />We will design and prepare sound wall plans for the project. Based on the proposed alignment <br />provided by the City in the RFP, we assume sound walls will be required adjacent to the <br />residential areas on north side of Warner Avenue. The sound wall plans entail plan and <br />elevation view of the wall with associated typical section and structural details needed for wall <br />construction. We assume Caltrans or City's standard plans can be used for design of proposed <br />sound walls. Due to potential liquefaction and existing differential settlements onsite, we have <br />assumed geotechnical investigation will be needed to determine if Caltrans or City's standard <br />plans can be used. Sound walls are assumed to be block walls based on Caltrans and City's <br />standard plans. Architectural design and features are excluded for this task. Structural analysis <br />are excluded from this scope of services. <br />7 1 P a g e <br />
