REVIEWED BY: Michael Throne, PE, Public Works Director�-,,� APPROVED BY: Doug Willmore, City Manager' ATTACHED SUPPORTING DOCUMENTS: A. Change Order No. 1 (page A-1) BACKGROUND AND DISCUSSION: The Capital Improvements Program (CIP) includes two (2) storm drain system projects that required a study of alternatives to determine the most cost-effective solution to flooding and erosion problems in portions of the City's existing drainage system. One project location is just north of Calle Entradero and just west of Palos Verdes Drive West. The other location, is near the intersection of Palos Verdes Drive South and Sea Cove Drive. On October 1, 2013 the City Council awarded a preliminary engineering contract to KPFF Consulting Engineers (KPFF) to provide preliminary design services for these locations. A final report was prepared and delivered to the City in June 2015. The recommended alternative for each location includes improvements to certain drainage structures and channels that require development of final engineering plans and specifications for eventual bidding and award of a Public Works contract to implement them. On December 15, 2015, the City Council awarded an engineering design contract to CWE Corporation (CWE) for another storm drain project, the Storm Drain Point Repair 1 Project, as recommended by Staff after a competitive proposal process. This design contract will provide final engineering plans and specifications (construction documents) for seven (7) locations needing repair in the City's storm drain system that were discovered during the last lining project in 2013. Staff would like to add scope to the Storm Drain Point Repair Project design contract with CWE to include preparation of construction documents for the projects studied earlier by KPFF. The work is quite similar to the work CWE is already doing. CWE has done an excellent job to date in its contract, and using them to perform this additional work will avoid delays that would result from a redundant selection process. It would also allow these two additional projects to be built sooner. Staff has negotiated Change Order No. 1 (Attachment A) to include the additional scope elements, costs and time to the existing contract. Per Section 1.8 of the contract, a change order of this magnitude must be brought to City Council for approval before it can be executed by the City's contract officer. Funds for this change order have already been appropriated in the budget as part of the Water Quality Flood Protection Fund. CONCLUSION: The City has a backlog of storm drain repair and improvement projects, and Staff would like to accelerate the schedule to complete certain projects by adding scope to an existing design contract begin performed by a competent consulting engineering firm selected in a competitive process. Therefore, Staff recommends awarding Change Order No. 1 to the CWE contract in the amount of $54,770. ALTERNATIVES: In addition to the Staff recommendation, the following alternative actions are available for the City Council's consideration: Discuss and take other action related to this item. 2 Project: Storm Drain Point Repair Design Project Change Order # 1 Attention: William Young C;rrY cF L 12Aricl io I-)ktf)s\/F.Fs CWE Corporation 30940 Hawthorne Blvd. 1561 E.
