The client required geotechnical engineering and construction observation services for a new $100 million 450,000-square-foot distribution center.
The firm* provided geotechnical and construction observation services for the construction of the 450,000-square-foot distribution center. The project also included constructing additional storage bin silos and the relocation of an existing rail line. Services included geotechnical drilling and sampling, laboratory testing, engineering analyses, observation and testing of soil and asphalt placement, backfill of utility trenches, reinforcing steel placement and concrete sampling and testing.
The in-situ soil conditions in the area of the proposed facility consisted of approximately 15 to 20 feet of uncontrolled fill materials. Due to the size of the building footprint and the depth of the soft and deleterious materials, it was not cost feasible to improve the soil conditions by means of undercutting and backfilling with suitable materials. Therefore, we recommended the use of an intermediate foundation system of rammed aggregate piers for bearing capacity improvement and settlement control purposes. Our team also worked closely with the owner, design team and contractor to develop the most cost-effective, efficient approach to solving the soil issues encountered in other areas of the facility, such as drive and parking areas and the rail line, all while ensuring that the client’s main goal of building a functioning facility was met.
