RECOMMENDATION: Award a construction contract, and authorize the General

submittals (SUBMITTALS).
FINANCIAL IMPACTS: Approximately $3,563,000, including design, bid price,
contingency, and construction management.
ALTERNATIVES /CONSIDERATIONS: Reject all bids, which is not recommended.
BACKGROUND: The project is the second phase of renovations anticipated in Diablo
(see Attachment 1). The Diablo Sewer Renovations, Phase 2 project, will renovate
and /or replace approximately 9,350 feet of 6 -, 8 -, 10 -, and 12 -inch sewer lines in
Danville and Diablo.
The existing sewer running along Calle Arroyo is very shallow, with some sections
having as little as 1 foot of cover. This sewer line was originally installed near a creek
bank, has difficult access, and requires frequent maintenance (every two to four
months). During the planning phase of the project it was determined that extensive
sewer realignment would be necessary to deepen existing shallow sewer pipes in the
Calle Arroyo area. In order to design a new sewer alignment, larger- than - typical efforts
were required to complete survey, field, and geotechnical investigations. Complex and

lengthy negotiations with the Diablo Country Club needed to be conducted in order to
obtain new right -of -way easements, which caused the bid to occur late in the season.
District staff prepared plans and specifications for the project. The Engineer's estimate
for construction of the Diablo Sewer Renovations, Phase 2, District Project 5976, is
$1,800,000. This project was advertised on June 11 and 17, 2013. Three sealed bids
ranging from $2,085,370 to $4,306,072 were received and publicly opened on June 27,
2013. The Engineering Department conducted a technical and commercial review of
the bids and determined that California Trenchless, Inc. is the lowest responsive bidder
with a bid amount of $2,085,370. A summary of bids received is shown in
Attachment 2.
The District will administer the construction contract and will provide contract
administration, inspection, survey, office engineering, and submittal review. The funds
required to complete this project, as shown in Attachment 3, are $2,863,000. The total
cost of the Diablo Sewer Renovations, Phase 2, is anticipated to be $3,563,000. The
engineering level of effort to design a new and deeper sewer alignment, combined with
extensive coordination to obtain new right -of -way easements, and a changing bid
climate, resulted in the higher total project cost. Because of the condition of existing
sewers, frequent maintenance, location near a creek, difficult access, and already
negotiated right -of -way agreements, staff recommends award of this contract. This
project is included in the fiscal year (FY) 2013 -2014 Capital Improvement Budget (CIB)
on page CS -9. Staff has conducted a cash -flow analysis of the Collection System
Program budget and concluded that adequate funds are available for this project.
The Board found this project exempt from the California Environmental Quality Act at its
May 2, 2013, meeting.
RECOMMENDED BOARD ACTION: Staff recommends the following:
Award a construction contract in the amount of $2,085,370 for the construction of
the Diablo Sewer Renovations, Phase 2, District Project 5976, to California
Trenchless, Inc., the lowest responsive bidder, and
