MEMORANDUM
(May 5, 2009)
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Director of Public Works
Subject: Award construction contract for intersection improvements
located at the South White Chapel Boulevard and Continental
Boulevard to Quality Excavation, LTD. in the amount of
$516,054.21 and authorize construction phase contingencies
Action
Requested: Award construction contract for intersection improvements located at
the South White Chapel Boulevard and Continental Boulevard to
Quality Excavation, LTD. in the amount of $516,054.21 and authorize
construction phase contingencies.
Background
Information: The intersection improvements will consist of the construction of a
roundabout at South White Chapel Boulevard at Continental Boulevard
to improve traffic flow within the area. The project includes the
relocation and /or upsizing of existing utilities, drainage improvements
and the construction of sidewalks within the project boundary.
Construction of the intersection will be completed in phases and will
occur under traffic, as there are no appropriate routes within the area
to detour local traffic. The Contractor will shift traffic within the
intersection, as needed, to allow for construction.
The roundabout will incorporate design concepts from the City's Urban
Design Study which was approved by the Planning & Zoning
Commission and the City Council in 2008. A separate landscape
project will be awarded by the Community Services Department at the
completion of the Public Works construction project.
Four (4) bids were received on April 21, 2009. The bids were reviewed
by the design engineer, Teague Nall and Perkins. It was determined
that Quality Excavation, Ltd. had inadvertently miscalculated the
amount bid on a pay item. The correction adjusted the results of the
original bid tabulation. The original bid amounts and the adjusted bid
amounts are as follows:
BIDDER BID AMOUNT

Jackson Construction, Ltd.

$653,159.50 $653,159.50
$865,802.50 $865,802.50
Teague Nall and Perkins recommends award of the contract to the
low bidder, Quality Excavation, Ltd. City staff concurs with this
recommendation.
Financial
Considerations: The recommended contract award amount is $516,054.21. Staff also
recommends that the City Council approve an approximate 10%
construction phase contingency of $51,945.79 in addition to the
award of $516,054.21 for a total project budget of $568,000.00.
Staff recommends funding the project from the following existing CIP

209499 - 598801 -R0011 137,158.97
Project Budget 568,000.00
Strategic Link: The construction of the roundabout at the intersection of South White
Chapel Boulevard and Continental Boulevard links to the City's
strategy map relative to the focus areas of Mobility, Infrastructure, and
Performance Management and Service Delivery. The specific
corporate objectives that are met by this construction project include:

maintain high quality public assets; and Providing travel convenience

RE: S. White Chapel Blvd./ Continental Blvd. Intersection Improvements
(TNP No. LEN 06289)
Dear Gordon:
On Tuesday, April 21, 2009 bids were received at 10:00 AM for the above referenced
project. A total of four formal bids were received, then opened and initially read as follows:
Contractor/ Bidder
Total Amount Bid
Quality Excavation, LTD.
$
519,618.21
JLB Contracting, LLC.
$
573,445.77
Stabile & Wynn, Inc.
$
653,159.50
Jackson Construction, LTD.
$
865,802.50
In the process of examining and checking the bids, the following errors were found in the
bid proposal for Quality Excavation, LTD.ontractors, Inc.:
1. The Amount Bid for Pay Item No. 1A -33 ($35,927.10) was calculated
incorrectly. When multiplying the quantity 3,269 SY by the Unit Bid Price of
$9.90 per SY the Amount Bid should be 32,363.10. This correction reduced
Quality Excavation's Total Amount Bid by $3,564.00.
With these corrections the adjusted bid tabulation results in the following official bid totals:
Contractor/ Bidder
Total Amount Bid

516,054.21

As requested, we have evaluated the low bid and found it to be complete and responsive.

Mr. Gordon J. Mayer, Jr., PE, August 24, 2009, Page 2 of 2
submitted a few weeks prior to the bid. The General Provisions of the contract documents
gives the City the option of waiving this irregularity. Based on prior experience with this
contractor, we recommend that the construction contract be awarded to Quality Excavation,
LTD. for the total amount bid of $516,054.21.
