City Council Meeting: June 23, 2009
Agenda Item: 1-G
To: Mayor and City Council
Subject: Wastewater Main Replacement/Upgrade Project
Staff recommends that the City Council authorize the City Manager to negotiate and execute a professional services agreement with Psomas in an amount not to exceed $540,000 plus a 10% contingency of $54,000 for a total of $594,000 to provide design services for the Wastewater Main Replacement/Upgrade Project.
The Wastewater Main Replacement/Upgrade Project will construct improvements to existing sewer pipelines at various locations to ensure adequate and reliable services to customers. Psomas is recommended for design services associated with the implementation of this project. Funds for this service are available in the existing Wastewater Main Replacement Capital Improvement Program account.
In 1994, the Northridge Earthquake inflicted significant damage to the sewer collection system. Following the earthquake, the City implemented a sewer repair program and by early 2004, the City completed the majority of repairs, replacements, and upgrades to the existing wastewater system. Operations and maintenance staff of the Water Resources Division has identified several areas of the system that require additional work to improve reliability and reduce maintenance requirements.
Staff reviewed maintenance records, performed field investigation to identify the most problematic areas of the wastewater collection system, and based on this information, developed a priority list. This report recommends authorizing a professional services agreement to provide design services for the highest priority improvements, which include development of plans and specifications for wastewater main replacements and upgrades of approximately 19,500 linear feet of wastewater mains in various locations throughout the City. These wastewater mains are located at the following locations:
New Maintenance Hole at
Place North -
Sewer at 1300 Block of
Sewer at 1400 Bock of
On March 19, 2009, a Request for Proposals was posted on the Citys website and Planet
Bids soliciting proposals for professional design services for the Wastewater Main Replacement/Upgrade Project. On April 9, 2009, nine
proposals were received. A
selection committee from the Civil Engineering Division and Water Resources
Division reviewed the proposals. The
selection criteria included the firms technical competence; understanding of
the projects scope; direct experience on similar projects; approach to the
work; qualifications of the proposed staff; staffing capabilities to meet the
desired time frames; and cost of services.
On April 20, 2009, the selection committee interviewed the four highest
ranked firms: Cannon; Psomas;
RBF; and FUSCOE. The selection
committee recommends Psomas to provide design services for this project. Psomas has extensive sewer main design experience
for municipalities and sanitation districts in
