BACKGROUND
Arcadis U.S., Inc. was selected as part of a competitive, qualifications-based solicitation process to design Bay Bridge Pump Station Replacement, Project No. 5-67. At the time of the solicitation, the Orange County Sanitation District (OC San) documented its intent to approve a subsequent agreement to the design consultant for the continuation of engineering services during construction.
The Bay Bridge Pump Station and associated force mains were constructed in 1966 on East Coast Highway just east of the Lower Newport Bay Channel. The pump station and force mains are critical to OC San's infrastructure as it conveys over half of Newport Beach's wastewater. The pump station is almost 60 years old and at the end of its useful life. The existing force mains were previously lined, are at the end of their useful life, and need to be replaced with a larger size for improved reliability. The force mains will be constructed under Lower Newport Bay Channel via microtunneling. It is imperative that the facility and force mains be upgraded to ensure continuous service.
