MEMORANDUM
(June 7, 2016)
To: Shana Yelverton, City Manager
From: Rob Cohen, P.E. Director of Public Works
Subject: Sanitary Sewer System Improvements
Action
Requested: Reject the bid for the construction of Sanitary Sewer System
Improvements.
Background
Information: In November 2014, with the approval of City Council, Baird,
Hampton & Brown Inc. initiated the design of the sanitary sewer
system improvement project. The project consisted of the
construction of sanitary sewer at four different locations in the City -
Summerplace Lane, Commerce Street and Market Loop, North
Carroll Avenue and East Highland Street, North Carroll Avenue and
Casey Court.
The first two locations involved rehabilitation and reconstruction of
the existing sanitary sewer while the next two involved new
construction. The existing sanitary sewer required reconstruction to
overcome several deficiencies such as size, shallow depth, sags
and flat slopes resulting in very frequent maintenance by the City
staff. Altogether, approximately 5,500 LF of 8-inch sanitary sewer
pipe was proposed to be constructed with this project. In addition
to the above listed work, a deteriorating and undersized corrugated
metal storm sewer line at Summerplace Lane was proposed to be
replaced with a new 36-inch reinforced concrete pipe (RCP).
All the projects were lumped together into one contract with the
expectation of economies of scale that would result in a better bid
price and reduced overall project costs associated with
engineering, administration and inspection. All projects were
approved and $1,835,000 was dedicated for this initiative.
The design and project specifications were completed in April 2016
and advertised to bid on May 1 , 2016 and May 8, 2016 in the local
newspaper. The advertisement was also posted on the City
website. The bidding was performed in compliance with the Texas
government code (TGC) guidelines. One (1) bid was received on
Item 4C
May 17, 2016. The bid was reviewed by Baird, Hampton & Brown,
Inc. and the City staff. The bid information is seen below:
BIDDER BID AMOUNT OPCC
Wilson Contractor Services $1 ,934,897 $1 ,381 ,000
The Opinion of Probable Construction Cost (OPCC) prepared by
the consulting engineer was underestimated by approximately 40%.
Contractors that pulled plans but failed to bid on the project were
contacted. Reasons that bids were not provided for this project
included contractor capacity was maximized, abundant work,
methods of construction (direct bore versus open trench), project
locations and scheduling. Portions of the work were required to be
completed during the summer months while school was not in
session.
Following options can be considered by the City Council:
a. Authorize additional funds to the project budget, in the
amount of approximately $465,000, to cover engineering,
material testing and construction contingencies and award
the contract to Wilson Contractor Services
b. Re-bid as is early next year and provide more time for the
contractors to compile bids.
c. Re-bid as individual projects
Based on the current market condition and feedback from the
contractors and engineers, staff recommends Option B.
Even with this option, staff requests additional funds to be added in
the FY2017 budget in the amount of $465,000 for a total project
cost not to exceed $2,300,000 to cover similar uncertainty.
Financial
Considerations: Funding for the 8-inch Sewer Line along North Carroll Avenue from
Highland Street to Whispering Lane and 8-inch Sewer Line along
Summerplace Lane from Highland Street to Dove Creek Trail was
approved in the FY2014 Utility Fund budget. The funding for the 8-
inch sewer Line along Market Loop and Bank Street lift station was
approved in the FY2015 Utility Fund budget. Funding for
Summerplace drainage improvements was approved in the FY2016
Storm Water Utility System Fund.
Strategic Link: This project links to the City's strategy map relative to the focus
area of Infrastructure by adhering to providing and maintaining high
quality public assets.
Item 4C
