Background Information:
The City Council awarded the construction contract for Bowman Road Drainage Improvements
to Austin Engineering Co., Inc., R -08-06-26-10C2, on June 26, 2008 for $1,135,197.00. This
project will provide more efficient drainage, improve the appearance and appeal of the
neighborhood, and facilitate the City's maintenance efforts.
- CONTINUED ON NEXT PAGE -
During construction, two water mains were found to be in conflict with the proposed
improvements, the installation detail for the Heathwood Channel storm sewer was contrary to
the installation requirements of the manufacturer, necessary changes in the project design in a
few areas became apparent during construction, and a row of hackberry trees that previously
had not been contemplated for removal in fact required removal to ensure proper installation
of the improvements and to prevent possible future damage to the improvements or property
in the vicinity, especially if the trees subsequently died. Items previously provided in the
contract related to the scope changes are being eliminated in this order as appropriate.
