On September 19, 2005, the City awarded a contract for the Main Street
Water Main Improvements Project to A. R. Sarmiento, Inc. for the
estimated amount of $341,220 plus a ten percent contingency totaling
$375,342. This project provides for construction of a new water main and
appurtenances along Main Street from MacArthur Boulevard to Sunflower
Avenue.
The following three items are responsible for the cost increases:
1. The limited access to the Hutton Center offices has prompted the
request to have the contractors work longer hours and Saturdays to
mitigate the impact to the offices and to complete the project as
soon as possible.
2. During construction, concrete pavement was encountered beneath the
existing asphalt street. The concrete, estimated to exist along the
entire length of the project, was not shown on the plan.
3. At several locations existing utilities were in conflict with the
new water main. To work around these utilities the contractor needs
to install the water main at a lower depth.
These unforeseen conditions will result in additional costs related to
overtime work, saw cutting, demolition, disposal, and installation of the
water main at a deeper level. The extra work will be done on a time and
materials basis.
Since this change order will exhaust the project contingency, the
Council's approval is required to cover this extra cost and preserve the
project's contingency for any additional project unforeseen conditions.
Estimated cost = $69,500
FISCAL IMPACT
The cost for the change order is estimate at $69,500. Funds are available
in the Water Utility Capital Projects Fund (account no. 66-579-6635).
