INFORMATIONAL MEMORANDUM
To: Mayor Haggerton
Utilities Committee
From: Public Works Director(`(
Date: May 26, 2009 Q'
Subject: Side Sewer Installation at 13906 51 Avenue South
Project No. 09 -SW02, Contract 09 -057
Change Order No. 1
ISSUE
Approve Change Order No. 1 to Contract Number 09 -057.
BACKGROUND
Jim Haggerton, Mayor
Duane Cameron Bulldozing was awarded the construction contract for side sewer
installation at 13906 51 Avenue South for $11,582.31, plus sales tax. Council approval
was not necessary for the original contract as it was under the $25,000.00 approval
threshold. The Notice to Proceed was issued March 31, 2009.
ANALYSIS
The additional work in Change Order No. 1 is the result of extra labor, equipment and
materials required to install side sewer to the house at 13906 51 Avenue South. The as-
built plans show a side sewer stub out to the house. However, after many hours of video
inspection and excavation, a sewer stub was not found. A new stub had to be installed and
the sewer main was found to be 18 feet deep. This is an extraordinary depth that was not
expected.
This change order will add $28,317.28 to the original contract for a new total contract
amount of $39,899.59 (plus tax). Remaining budget is available for this change order from
the $75,000 Sewer Infiltration Inflow (I &I) Project (page 122, 2009 CIP).
RECOMMENDATION
The Council is being asked to approve Change Order No. 1 for the Side Sewer Installation
at 13906 51 Ave S Project with Duane Cameron Bulldozing in the amount of $28,317.28
for consideration at the June 22, 2009 Committee of the Whole meeting and subsequent
July 1, 2009 Regular Meeting.
