Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a contract modification for professional engineering services with AECOM Technical Services, Inc. for the DOSD Sanitary Pump Station SA-13 Evaluation & Upgrade Project, CIP #650660-100013, in an amount up to $417,248.79.
The initial phase of this contract provided Professional Engineering Services for Preliminary Design (Step 1). This phase, the second phase, will provide Professional Engineering Services for Detailed Design and Bidding Services (Step 2). The third phase will provide engineering services during construction (Step 3).
The scope of work for this project will generally include a complete assessment, evaluation, and refurbishment of Sanitary Pump Station SA-13 so that it can remain in service for the next 20 years with only routine maintenance. The building structure and the systems and equipment within may need refurbishment to some degree, including but not limited to pumps and motors, electrical and power generating equipment, security systems, instruments and controls, wet well structures, the sewer pipes within the boundaries of the site, electrical cabling and duct banks, parking lots, grounds and fences, and HVAC systems. This refurbishment must bring the pump station into compliance with all current building and safety codes.
Step 1 of this project, Preliminary Design, included the following tasks: 1. A review of the existing pump station, 2. A condition assessment and evaluation of the existing pump station, 3. Identification and evaluation of design alternatives, 4. Development of design criteria and basis of design, and 5. Preparation of a Detailed Design Memorandum / Preliminary Design Report (PDR) / Condition Assessment Report.
This phase will request a modification (Modification No. 1) to the Professional Engineering Services Agreement to provide funding for Step 2, Detailed Design. Detailed Design will prepare construction contract ...
