Introduction

This report recommends that the City Council award a contract to Modern Continental Construction Company, Inc. in the amount of $9,707,025 for construction of the Pacific Coast Highway Sewer Replacement Project of the Coastal Interceptor Sewer. This report also recommends that the City Council appropriate $1,170,702 from the Wastewater Fund balance to account no. 31-760-661-20099-8905-99124 for the City=s 10% set aside until final audit.

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. 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 Moss Avenue Pumping Station=s structural shell and construction for the Appian Way portion of the CIS is nearing completion.

Discussion

The Pacific Coast Highway Sewer Replacement Project includes microtunneling approximately 8,500 feet of 60-inch diameter pipe under Pacific Coast Highway from the northerly City limits to the 1550 Parking Lot, north of the Santa Monica Pier. Microtunneling is the unmanned entry method that uses a remotely operated microtunneling boring machine to install pipe underground with minimum surface disruption. Also included is the traditional Acut and cover@ installation of 7,500 feet of 12-inch diameter pipe, which will serve as a local collector sewer line for beachfront properties.

A Notice Inviting Bids for the construction of the Pacific Coast Highway Sewer Replacement Project was published in the Argonaut on March 3 and 9, 1999. The Notice Inviting Bids, along with the plans and specifications, was also sent to eight construction journals and six women/minority business enterprise (WMBE) associations. Bid packages were requested by 35 contractors. The City Clerk=s Office received five sealed bids which were publicly opened and read aloud on April 12, 1999 by the Deputy City Clerk. The bid results were as follows:

CONTRACTOR AMOUNT
Modern Continental Construction Co., Inc. $ 9,707,025
Vadnais Corporation $10,851,500
Malden Buntich Construction Co., Inc. $11,289,250
Dillingham Construction $12,702,636
BHR - Garver, Inc. $16,769,020

ENGINEER=S ESTIMATE:

$10,000,000

The low bidder, Modern Continental Construction Company, Inc., supplied the City with numerous references. Modern Continental Construction Company, Inc., has been in operation for 33 years, has successfully constructed heavy public works projects ranging in size from $5 million to $800 million and has approximately $1.5 billion of heavy construction underway in both the United States and abroad. As a part of a recent transaction, the key personnel and the business of Westcon Microtunneling are now part of Modern Continental Construction Company, Inc. Westcon Microtunneling, the microtunneling division of Modern Continental Construction Company, Inc., meets all of the experience requirements in the Contract Documents and has provided the City with many projects as references. These projects include the 12th Street Pipeline project in San Jose, the New Saint James Avenue Interceptor in Boston. MA., and the Morro Hills Waterline undercrossing of the environmentally sensitive San Luis Rey River in Oceanside, CA. In addition to the references specifically provided for the Pacific Coast Highway Project, staff contacted additional references with positive results. These include the Lake San Marcos undercrossing in San Marcos, CA. for the Vallecitos Water District (VWD), which has recently awarded an additional project to the Westcon Microtunneling Division of the Modern Continental Construction Company, Inc. because of their successful installation in San Marcos.
