City Council Meeting: June 23, 2009

Agenda Item: 1-G

To: Mayor and City Council

From: Lee E. Swain, Director of Public Works

Subject: Wastewater Main Replacement/Upgrade Project

Recommended Action

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.

Executive Summary

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.

Background

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.

Discussion

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.

Contractor/Consultant Selection

On March 19, 2009, a Request for Proposals was posted on the City’s 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 firm’s technical competence; understanding of the project’s 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 Southern California, an experienced project design team, and the ability to complete the design of the project in an expeditious manner. Psomas’s hourly rates are compatible with all proposals by other consultants.
