SUBJECT: Recommendation to Award a Construction Contract for the Moss Avenue Pumping Station Phase 2 Project of the Coastal Interceptor Sewer to Pacific Mechanical CorporationIntroduction
This report recommends that the City Council award a contract to Pacific Mechanical Corporation in the amount of $2,546,000 for construction of the Moss Avenue Pumping Station Phase 2 Project of the Coastal Interceptor Sewer.
Background
The Coastal Interceptor Sewer (CIS) collects sewage from the City of Los Angeles, north of the City limits and, with additional flows from the City of Santa Monica, carries it to the City of Los Angeles
= Hyperion Plant for treatment. Many sections of the CIS were damaged by the 1994 Northridge earthquake and projects are underway to repair the damage. The cities of Santa Monica and Los Angeles are working jointly on this rehabilitation effort, with Santa Monica serving as the lead agency for that portion of the CIS within the City of Santa Monica. The entire CIS Project includes the Pacific Coast Highway sewer replacement, the Appian Way project, the Ocean Avenue to Pico Boulevard to Main Street sewer rehabilitation, the Ocean Avenue to Neilson Way relief sewer, and the Moss Avenue Pumping Station (MAPS). The CIS Project also includes the replacement of two flow-monitoring stations which monitor flow in and out of the City at the northern and southern City limits. Construction has been completed for the replacement of MAPS structural shell and for the Appian Way portion of the CIS.Discussion
The replacement of the existing MAPS is being constructed in phases. The station
=s below grade structural shell was completed in 1998, the Appian Way project was completed in 1999 and the station is now ready for its second phase of construction. The second phase consists of the installation of electrical, mechanical, instrumentation, pumping and piping components of the station, as well as construction of above-grade structural walls and architectural screening elements.A Notice Inviting Bids for the construction of the MAPS Phase 2 project was published in the Argonaut on April 15 and 22, 1999. The Notice Inviting Bids, along with the plans and specifications, were also sent to eight construction journals and six women/minority business enterprise (WMBE) associations. Bid packages were requested by 41 contractors. The City Clerk
=s Office received four sealed bids which were publicly opened and read aloud on May 25, 1999 by the Deputy City Clerk. The bid results were as follows:| CONTRACTOR | AMOUNT |
| MERCO Construction Engineers, Inc. | $2,464,370 |
| Pacific Mechanical Corporation | $2,546,000 |
| Olsson Construction | $2,798,000 |
| Western Summit Constructors, Inc. | $2,931,703 |
| ENGINEER=S ESTIMATE: | $2,700,000 |
Section 2.24.072 of the Santa Monica Municipal Code sets forth the criteria under which staff may determine the lowest responsible bidder as:
=s financial resources;(1) The quality of the materials or services offered;
(2) The ability, capacity and skill of the bidder to perform the contract or provide the material or services;
(3) The capacity of the bidder to perform the contract or provide the material or service promptly, within the time specified, and without delay or interference;
(4) The sufficiency of the bidder
(5) The character, integrity, reputation, judgment, training, experience and efficiency of the bidder;
(6) The ability of the bidder to provide such future maintenance or service as may be needed.
After considerable investigation and analysis, staff and the City
=s consultants for the CIS project find that Pacific Mechanical Corporation (PMC) qualifies as the lowest responsible bidder. The reasons for selecting PMC are as follows:1. PMC has successfully constructed the structural shell for the MAPS. Because PMC is already familiar with project conditions, they can begin work with a minimum of additional mobilization. This translates into greater assurance of on-time completion, which will reduce the risk of sewage spilling from temporary piping on site.
2. PMC is currently constructing the Dry Weather Runoff Reclamation Facility (DWRRF) for the City, which is adjacent to the MAPS. Because the two projects share an electrical transformer and standby power generator, and the electrical and instrumentation controls for the DWRRF are located within the MAPS structure, coordination between the two projects is essential. PMC will provide the City with the best performance on these critical interfaces, since the projects will be constructed simultaneously by one contractor. Additionally, delays will be minimized, and the City will incur lower staff and consultant costs by working with one contractor. Staff believes that consultant cost savings will more than offset the difference in costs between the MERCO and PMC bids.
3. The City has experienced consistently high quality service from PMC, and references from other government agencies are excellent. Similar projects include: four pump station upgrades for the East Bay Municipal Utility District; a wastewater treatment plant for the City of Justine, CA; sewage pump stations for the cities of Santa Rosa and Burlingame, CA; a Pond Influent Pump Station Upgrade for the City of Petaluma; and Joint WPCP Covers for the primary treatment facilities for Los Angeles County Sanitation District.
Of the two bids below the Engineer
=s estimate, the PMC bid is the lowest responsible bid since it provides for greater coordination with adjoining projects and City staff which increases the probability of successful completion of the project in a timely manner. This project is to begin in August 1999 and will be completed in April 2000.Budget/Financial Impact
FUNDS REQUIRED
| Contract | $2,546,000 |
| Contingency | $ 350,000 |
| TOTAL | $2,896,000 |
Funds in the amount of $2,896,000 are available in CIP Account Number C31094600., ACity of Los Angeles CIS Projects". Under the Wastewater Services Agreement with the City of Los Angeles, the City of Los Angeles and the contract agencies other than Santa Monica are responsible for approximately 97% of all capital improvement costs for the CIS project.
Recommendation
Staff recommends that the City Council:
1. Award a contract to Pacific Mechanical Corporation, the lowest responsible bidder, in the amount of $2,546,000 for the Moss Avenue Pumping Station Phase 2 project of the CIS;
2. Authorize the City Engineer to issue any necessary change orders to complete additional work within budget authority and in accordance with the Administrative Instructions on Change Orders; and
3. Authorize the budgetary items detailed in the Budget/Financial Impact Section of this report.
