CMJ Engineering - Project Feature

Target selected CMJ to perform the geotechnical investigation for their new Target Distribution Center T-3801. The site is located at the northwest corner of the intersection of Railport Parkway and Power Way in Midlothian, Texas.

The project consists of a one-story, 1.4-million square foot distribution facility, whose building perimeter is approximately 1 mile. In addition, large parking areas are planned to the north, east, and south of the facility. Cuts on the order of 0 to 15 feet and fills on the order of 0 to 13 feet are planned to achieve final grade in the building and parking areas.

Soils at this site consist of clays, shaly clays, and shaly clays/shale of the Eagle Ford geological formation of Cretaceous Age. The soils are highly plastic and are underlain by dark gray shale, which leads to the recommendation for excavated, reinforced concrete straight-sided drilled shafts (piers/caissons) to transmit structural loads to the bearing material.

Geotechnical design considerations included expansive soil movements, pier support via downward and upward loads, effects of deep fills and cuts, sulfate-induced heaving potential, pavement and wall design, and effective ways to provide efficient means to aide the construction schedule.
