Explanation
1. BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services agreement with CH2M Hill Engineers, Inc. for the Parsons Avenue Water Plant (PAWP) Treatment Upgrade Project, Division of Water Contract No. 1095.
The Original agreement (EL007318, Ord. #1073-2007) entailed professional consulting/engineering services to provide full-service assistance to the City to evaluate options and design an upgrade to the Parsons Avenue Water Plant to reliably treat a 50 MGD combination of ground water, ground water under the direct influence of surface water (GWUDI), and surface water. Tasks identified Preliminary Engineering, including Bench-Scale Demonstration and Microbial Studies, which were compiled into a Preliminary Engineering Report.
Modification No. 1 (EL012078, Ord. #1030-2011) allowed for completion of the Preliminary Engineering Report, including finalization of a series of Technical Memorandums which summarized the findings throughout the preliminary investigation into plant upgrades.
Modification No. 2 (EL013280, Ord. #1187-2012) allowed for completion of the detailed design and bidding portion of the project. It included 30%, 60% and 90% design submittals and review meetings, Value Engineering, regulatory submittals, a geotechnical investigation, and a Full-Scale Microbial Demonstration Study as necessary.
Modification No. 3 (current) provides partial funding for Engineering Services During Construction. Construction is anticipated to begin in February 2015 and last for approximately 3.5 years. Services under this modification will also include onsite construction representation, submittal and RFI reviews, change order preparation, special inspections, training and asset management services and preparation of records documents, online training, an ArcFlash Study and other engineering services during construction as outlined in the contract scope of work.
