PROJECT NOTICE/JUSTIFICATION: This was a Work Order bridge related repair project primarily for miscellaneous type of bridge repair work throughout the City of Houston. The scope of the work included mobilization, traffic control, removal and replacement of approach slabs, guard rails, slope paving, etc.
DESCRIPTION/SCOPE: The project detailed in the contract was for bridge related repairs in various locations throughout the City of Houston. The scope of work was determined by work orders which were issued on an as-needed basis. Two work orders were issued. Work order #1 was issued to complete the repair of the Gulfbank Bridge over the Hardy Toll Road. Work order #2 was issued to repair the southbound Hillcroft Bridge over Willow Waterhole. The project was prepared in-house by the Department of Public Works and Engineering staff with 550 calendar days allowed for construction. The project was awarded to ISI Contracting, Inc. with an Adjustment Factor of 1.250 rather than a monetary amount. The Adjustment Factor was applied on individual unit price items in the Contract documents. Estimated work order prices were calculated by multiplying the Unit Quantity of each item in the work order by the Unit Price and the Adjustment Factor. The total expenditure available for the entire project was $850,000.00.
