GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION:
Approve a Task Order limit increase of $70,000 to the Professional Design Services Agreement with Dudek to provide professional engineering services for CenGen Cooling Water Pipe Replacement at Plant No. 2, Project No. FE20-04, Task Order No. FE18-00-03-03, for a total amount not to exceed $370,000.
body
BACKGROUND
The Orange County Sanitation District's (OC San) Central Power Generation System (CenGen) at Plant No. 2 was constructed in the early 1990's to generate electricity using digester gas. During normal operating conditions, CenGen supplies 100% of the electricity needed to run Plant No. 2 operations. Cooling water is used to keep the CenGen engines from overheating. The cooling water is highly corrosive and has caused the existing metallic piping to develop leaks. This project will replace the existing CenGen cooling water piping and all associated instruments and appurtenances.
Dudek was selected as part of a competitive, qualifications-based Task Order solicitation process to design and provide construction support services for CenGen Cooling Water Pipe Replacement at Plant No. 2, Project No. FE20-04. The replacement of the cooling water instruments was added as a Task Order amendment.
RELEVANT STANDARDS
* Sound engineering and accounting practices, complying with local, state, and federal laws
* Ensure the public's money is wisely spent
PROBLEM
The FE20-04 construction project is behind schedule due to delays caused by the contractor. As a result, the original budget is insufficient to cover the extended project timeline. Also, the decision to replace the old cooling water instruments instead of reusing them used up more of the design budget and made construction support more compl...
