Consider and take action on a resolution authorizing change order no. 1, in the amount of $30,000, and change order no. 2, in the amount of $158,300, with Weisinger Incorporated for the Water System Improvements Project - Dickinson Booster Pump Station Well, through the General Land Office, Community Development Block Grant, Disaster Recovery, Round 2.2 Program, GLO Contract No. 13-179-000-7292 (Director of Public Works)
Background:
Approval of this resolution will authorize the construction Change Order No. 1 in the amount of $30,000 and construction Change Order No.2 in the amount of $158,300.
On November 24, 2015, City Council approved a construction contract with Weisinger, Inc for the Water System Improvements Project - Dickinson Booster Pump Station Well, in the amount of $1,193,300.
Change order no. 1, in the amount of $30,000, represents two additional water well samples which were used to investigate every possible water-bearing sand layer to determine the maximum production capacity of the well. The City’s consultant recommended two additional test well samples be obtained to analyze the highest possible yield capacity of the well.
Change order no. 2, in the amount of $158,300, represents the addition of a blending water line and well pipe and pump modifications to accommodate the anticipated water well yield capacity. A source of blending water is available in an existing water line on Ohio Street, which is east of the Dickinson Water Plant site. Extending 1,850 linear feet of 8-inch water line, from Ohio Street to the Dickinson Water Plant, is the consultant’s recommended method of providing a beneficial project result. Based on this final well analysis, the well design, the blending water line addition, and the piping and pump modifications this project will provide a producing water well with a yield capacity of approximately 400 gallons per minute of drinking water meeting TCEQ water quality requirements.
This is a Hurricane Recovery Project being funded by the General Land Office of the State of Texas to provide for disaster recovery and restoration of infrastructure for communities impacted by the 2008 hurricanes. Funds are allocated by the United States Department of Housing and Urban Development through the Community Development Block Grant Program. League City’s contract number is 13-179-000-7292.
