Executive Summary Windward School, a private college - preparatory school serving grades 7 -12, leases land at the Charnock well field in West Los Angeles from the City for use as athletic fields. The Windward School Administration desires to modify the athletic field layout and requests the City relocate an existing water production well. In January 2012, Council approved an amendment to an existing agreement with BVCI to provide project management and construction services for the relocation of an existing water production well at Windward School. Staff recommends a second amendment to this agreement with BVCI, in the amount of $395,235, to manage the construction of the new well, demolition of the old well and manholes, installation of new piping, and the re- routing of electrical lines for the Windward Well Relocation Project, for a total contract amount of $62,096,354. Additionally, staff recommends RCS to provide hydrogeological observation and inspection services in the amount of $79,640. Windward School will 1 reimburse the City for Black & Veatch's services and Richard C. Slade's services in the amount of $1,896,292. Background On January 24, 2012, an amendment to the Design -Build Agreement No. 8892 (CCS) with BVCI was authorized to provide project management and construction services for the relocation of the well in an amount not -to- exceed $1,421,417 from the available contract contingency. Discussion Amendment to Design -Build Agreement BVCI received three subcontract bids on May 7, 2012 for the well drilling and prepared a proposal for all project expenditures. The bids received were higher than the engineer's estimate prepared by RCS because treatment of the pumped water during well development is more costly than originally estimated. Windward School is aware of the cost increase and desires to move forward with the relocation of Well CH -15. Windward School will pay for all project costs as outlined in the Payment Agreement executed April 3, 2012 between the City and Windward School. Staff recommends increasing the project budget to allow BVCI to complete construction of the well relocation. This project would begin in June 2012 and completion expected by December 2012. Consultant Selection In November 2011, Windward contracted with RCS to provide design services of the well. Staff also recommends utilizing the services of RCS for hydrogeological observation, geological logging, well casing installation oversight, and inspection services. RCS is a consulting groundwater geologist with substantial experience in municipal water supply wells and is currently the Engineer of Record for the well relocation design drawings. Because of their history and experience with this project staff recommend RCS as the best choice. 2 Financial Impacts & Budget Actions The amendment to be awarded to Black & Veatch is $395,235 for a new total of $1,816,652.
