TRA Issues Official Notice to Proceed With Repair of Lake Livingston Dam

Livingston - the Trinity River Authority of Texas has issued an official notice to proceed to Archer Western Contractors, Ltd. on the repair of Lake Livingston Dam which was severely damaged by Hurricane Rita.

The contractor has projected that the repair effort will take 160 calendar days to substantial completion, and 200 days to full completion. The clock started ticking on this schedule on January 6, 2006.

The low bid for this major repair project was $7.698 million. TRA estimates that the total project cost of the repair will be in the vicinity of $9.660 million.  Project costs include engineering, construction inspection, other related construction issues and an allowance for contingencies.  The Houston City council has taken action to fund the balance of costs not ultimately funded by FEMA.  Lake Livingston represents approximately 70 percent of Houston’s available water supply.

The contractor has begun mobilization on site and has issued a purchase order for 25,000 tons of eight inch crushed rock bedding material and 72,000 tons of 32 inch limestone rip rap to replace the 11,000 linear feet of upstream slope protection that was stripped away by hurricane generated wave action. Approximately 70 percent of the required replacement rock is currently available for shipment at the quarry where it was produced in the vicinity of Corsicana.

Shipment of the rock is expected to begin during the week of January 8.  It will be moved to the dam at the rate of 1,000 tons per day. This will represent in the vicinity of 50 truck loads per day. The materials will be unloaded on the western end of the dam’s embankment and repair work will begin from the west end to the east end.

TRA expects that the contractor will have the required personnel, equipment and materials available and be ready to proceed by January 19.
