Page 1 of 7 POSITION PAPER Board Meeting Date: June 4, 2015 Subject., AWARD A CONSTRUCTION CONTRACT AND AUTHORIZE THE GENERAL MANAGER TO EXECUTE CONTRACT DOCUMENTS SUBJECT TO SUBMITTAL REQUIREMENTS WITH AZTEC CONSULTANTS, INC. FOR THE CONSTRUCTION OF THE TREATMENT PLANT SAFETY ENHANCEMENTS, PHASE 4 REVISED, DISTRICT PROJECT 7311 Treatment plant safety issues are identified by the District's Safety Suggestion Program, safety committees, safety audits, and periodic inspections. Through these programs, several items have been identified and included in the Treatment Plant Safety Enhancements, Phase 4 Revised Project. The scope of work includes constructing a hazardous materials containment area, a retaining wall at an eroding plant access road adjacent to a high voltage conduit run, handrail modifications, and other improvements to eliminate safety hazards. The POD administration building is over 30 -years old, and the Project will provide ADA accessibility for the parking lot, multipurpose room, POD entrance, and other POD locations. At the buffer properties, sidewalk and stairway improvements will be constructed between the Annex and the 4737 Warehouse. The Project will occur in multiple locations throughout the treatment plant and District properties as shown in Attachment 1. District staff prepared the plans and specifications for the Project. The Engineer's estimate for construction is $600,000. This Project was advertised on April 28 and May 5, 2015. Five sealed bids ranging from $553,500 to $704,000 were received and publicly opened on May 20, 2015. The Engineering Department conducted a technical and commercial review of the bids and determined that Aztec Consultants, Inc. is the lowest responsive and responsible bidder with a bid amount of $553,500. A summary of bids received is shown in Attachment 2. The addition of ventilation windows at Household Hazardous Waste Collection Facility (HHWCF) is included as an optional additive bid item. The additive bid price from the lowest responsive bidder is $25,500 and staff recommends that it be included in the Project. The total bid including the additive bid item is $579,000 and is included in the total Project cost shown in Attachment 3. The District will administer the construction contract and will provide contract administration, survey, office engineering, and submittal review. Inspection will be provided under the existing blanket agreement with Harvest Technical for construction inspection services. The funds required to complete this Project, as shown in Attachment 3, are $780,000. The total cost of the Treatment Plant Safety Enhancements, Phase 4 Revised, is anticipated to be $1,070,000. The proposed Project work is included in the FY 2014 -15 CIB on pages TP -13, GI -9, and GI -17. Each project will be charged its respective costs. The total estimated project costs shown in the CIB for the Treatment Plant Safety Enhancements, Phase 4 Revised, are $340,000; the POD ADA Project is $490,000; and the Buffer and Rental Project is $279,000.

FOR THE CONSTRUCTION OF THE TREATMENT PLANT SAFETY ENHANCEMENTS, PHASE 4 REVISED, DISTRICT PROJECT 7311 FY 2014 -15 Allocation Budget TP Program GI Program Authorized Estimated Allocations for Projects $ 4,486,000 $ 3,476,500 Supplemental Board Authorizations $ 0 $ 400,000 Allocations Returned from closeouts $ 0 $ 262,315 Total Board Authorized Allocations $ 4,486,000 $ 4,138,815 FY 2014 -15 Allocations to Date $ 1,940,450 $ 3,479,515 This Allocation $ 250,000 $ 530,000 Remaining unallocated Budget $ 2,295,550 $ 129,300 Staff has concluded that this Project is exempt from CEQA under District CEQA Guidelines Section 15302, because it involves replacement of existing public facilities at substantially the same locations and with the same purpose and level of activity as the facilities being replaced. There are no capacity increases resulting from this Project. This Project also is exempt under District CEQA Guidelines Section 15061(b)(3), since it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment. This certainty is based on the District's past experience with numerous construction projects of this nature, the relatively short distances involved, and the District's mitigating construction specifications. These specifications are standardized general and special conditions that are made part of the Project bid documents to address environmental considerations, such as protecting trees and riparian areas, as well as compliance with applicable federal, state, county, district, municipal, and local laws, ordinances, orders, and regulations. Approval of this Project will establish the Board of Directors' independent finding that this Project is exempt from CEQA. COMMITTEE RECOMMENDATION: The Engineering and Operations Committee reviewed the previous Treatment Plant Safety Enhancements Phase 4 Project at its meetings on February 11 and March 11, 2015, and agreed with the staff recommendation to reject all bids and rebid the project to include the most critical scope items. The Revised Project is of similar scope to the previous project and is below the engineers estimate for construction and total estimated project budget. For these reasons, the Committee recommended approval of the subject. RECOMMENDED BOARD ACTION: Staff recommends the following: Find that the Project is exempt from CEQA, 2.
