SR-6-O (23) 6-0 i :\ ~ : : .~~: .i GS:SES:LR:pam.CC1354/WP51 Council Meeting: January 26, 1993 Santa Monica, California TO: Mayor and City council FROM: city Staff SUBJECT: Award of Contract for the Sediment Sampling and Analysis Portion of the Breakwater Feasibility Study Introduction This report recommends that City Council authorize the City Manager to negotiate and execute a contract for the sediment sampling and analysis portion of the Breakwater Feasibility study to Leighton and Associates, in the amount of $72,900. Backqround In March 1986 the u.s. Army corp of Engineers conducted an initial appraisal regarding the reconstruction of the Santa Monica Breakwater. After this appraisal was completed a determination was made that further analysis in the form of a Feasibility Study was needed. During the 1989-90 budget process, the City Council approved co-funding this study with the Army Corps of Engineers. The study has three phases. The first was a reconnaissance study completed in 1989 which describes the study area, identifies the problems, and formulates a plan. The second phase further evaluates the design alternatives and generates costs data for each; this phase is now in process. The third phase will include the project design. The third phase will be undertaken only if the 1 6-0 J,~ r~ ~ "", ~ ~ , 1,1~' project is deemed feasible and if approved by the city. Discussion The sediment sampling and analysis includes: surveying for sample locations; obtaining and analyzing surface sediment and coring samples; evaluating proposed dredge sediment and the receiving beach site with mechanical and chemical analyses; and preparing a geotechnical and environmental report. This is required to evaluate the extent of Federal interest in reducing storm damage, navigation and related hazards along the shoreline of the city of Santa Monica. Federal interest is determined by comparing the costs of breakwater construction (including maintenance costs after construction) to the benefits of damage protection. When the feasibility study is completed, Staff and the Army Corps of Engineers expect to evaluate the benefits and the costs of various breakwater designs as they relate to the Pier, the beach and harbor. A Request for Proposals was sent to five professional firms on October 29, 1992. The city received two proposals on November 16, 1992, one from Leighton and Associates and another from Fugro- McClelland (West) Inc., as follows: Leighton and Associates Fugro McClelland Inc. $72,900.00 $98,500.00 2 The review committee charged with the selection of the consultant for this project included the city Engineer, the Economic Development Manager, a civil Engineer in the Engineering Division, and the U. S. Army Corps of Engineers' proj ect Manager. The committee recommended selecting Leighton and Associates because of their excellent performance with the City on the Safety Element of the General Plan and on the geotechnical studies requested in 1988 for the Santa Monica pier Restoration Project. Leighton and Associates has satisfactorily performed similar offshore field investigation projects with Port of Los Angeles and Port of Long Beach. Their proposal further includes three experienced WHBE/DBE subconsultants: Sea Surveyor, for the coring and the positioning survey: Hamilton Marine Services, Inc., for the vessel use; and Quiroz Surveying Inc., for additional surveying services. Work to be performed by these subconsultants totals approximately 65% of the total contract price. Budqet/Financial Analysis The City entered into a Cost Sharing Agreement in FY 1991-92 with the Army Corps of Engineers to finance a portion of the feasibility study. The proposal in this staff report for the hiring of a professional geotechnical consultant to perform materials sampling and analysis in the breakwater area fulfills the City'S obligation 3 regarding this agreement. FUNDS REQUIRED: Contract . . . . . $72,900 contingencies (7%) . . $ 5,100 Total: $78,000 Funds are available in Pier eIP accounts: 30-740-625-26890-8912- 99931 in the amount of $62,484, and 30-740-625-26990-8912-99923, in the amount of $15,516. Recommendation Staff recommends that City Council authorize the city Manager to negotiate and execute a contract with Leighton and Associates for the sediment sampling and analysis portion of the Breakwater Feasibility study in the amount of $72,900.
