American Electric Power Texas hired DBA as part of a larger Design-Build team consisting of Overland Contracting, Inc. and Black & Veatch to design and construct a power substation in Barnhart, Texas.
DBA’s scope of work included:
* Clearing & grubbing of 1.6 acres of private ranch land for the substation
* Clearing & grubbing of 3,500 LF of access road from U.S. Highway 67 to the substation
* Ripping and recompacting the subgrade which included the removal of very large rocks
* Importing suitable fill materials for the pad from 13 miles away
* Installing filter fabric for the roadway
* Installing gabion baskets at two low-water crossings along the access road
The roadway was constructed using a limestone base and because the site was sloped and extremely rocky, DBA crews had to level the site for the electrical substation equipment with 7-feet of fill on one corner.
Knowing the weather in Texas to be extremely unpredictable and having the potential to slow production and delay the project overall, DBA crews worked seven days a week with 10-hour days.
