FROM: Tom Tait, Public Works Services Director

Deen Buharie, Assistant Engineer
SUBJECT: CONTRACT WITH GENTRY BROTHERS INC. FOR THE SIXTH
AVENUE SEWER CAPACITY IMPROVEMENT PROJECT IN THE
AMOUNT OF $407,100
Recommendation: Approve
SUMMARY
The City of Arcadia's 2006 Sewer Master Plan study identified the section of sanitary
sewer pipe on Sixth Avenue as inadequate in accommodating the current flows in the
pipe. Under this project, the existing 8 -inch sanitary sewer main along Sixth Avenue
from Live Oak Avenue to Verner Circle will be replaced with a larger pipe to alleviate the
high demand on the existing sewer pipe and prevent potential sewer system overflows.
To ensure that the City is receiving the most competitive prices and quality service for
this work, a formal bid was conducted and Gentry Brothers Inc. submitted the lowest
responsive bid. It is recommended that the City Council authorize the City Manager to
execute a contract with Gentry Brothers Inc. for the Sixth Avenue Sewer Capacity
Improvement Project in the amount of $407,100.
DISCUSSION
The City's Sewer System Management Plan (SSMP) has a goal of zero sewer system
overflows and this is achieved through annual inspection and cleaning of the sewer
pipes, repair of broken pipes, and replacement of pipes flowing above their design
capacity. In addition, as part of the City's 2006 Sewer Master Plan, all sanitary sewer
mains were evaluated to compare existing flows through the pipes to the design
capacities of the pipes. Evaluation of the sewer pipe on Sixth Avenue, north of Live
Oak Avenue indicated that the sewer pipe is currently flowing above its design capacity
and is at risk of experiencing a sewer system overflow.

As a result, City staff worked with a design consultant to prepare plans and
specifications to replace the existing 8 -inch pipe with a 12 -inch pipe from Live Oak
Avenue to Longden Avenue, and a 10 -inch pipe from Longden Avenue to Verner Circle
(see attached location map of the project area).
A Notice Inviting Bids was published in the City's adjudicated publication and bid
packages were acquired by area contractors. On January 7, 2014, the Office of the City
Clerk received and opened ten sealed bids with the following results:

The Engineer's Estimate to complete this work was $700,000. In order to assure that
the project could be awarded within the approved budget of $600,000, the work was
divided into a base bid for work between Live Oak Avenue and Longden Avenue, and
an alternate bid for work between Longden Avenue and Verner Circle. In accordance
with the bid documents, all bids were evaluated on the basis of the base bid. Bids
received were very competitive and came in below the Engineer's Estimate. For
simplicity, the amounts shown above reflect the total amount for the base bid, plus the
alternate bid (total bid). Since the lowest responsive bid received was within the project
budget, the decision was made to include all recommended improvements.
The bid documents were reviewed for accuracy and content. Gentry Brothers Inc.
submitted the lowest bid. The contractor's license and recent projects completed were
investigated to ensure that they were completed successfully. Following this review, it
was determined that Gentry Brothers Inc. submitted the lowest and most responsive
bid, and is therefore capable of completing the project as defined in the bid documents.
