WDP performed a comprehensive geotechnical investigation for this 420,000 square foot food manufacturing facility including an on-site wastewater treatment plant and privately-owned railroad spur. Geotechnical design recommend- ations provided for foundation and floor slabs, below-grade walls, pavements, and site preparation/fill placement. WDP provided an on-site materials testing laboratory for all structural fill placement operations (approx. 1 million CY), foundation examinations and slab subgrade preparations, concrete placement (approx. 25,000 CY) structural steel and masonry, and paving operations (approx. 25 acres).
 

• The on-site laboratory provided rapid testing of soils and concrete materials, particularly for tilt-up panel erection based on concrete strength. 

• Marginally suitable site soils were either mixed with blasted rock to increase suitability and/or selective placement methods were employed to cost-effectively utilize all on-site soils without compromising long-term performance. 

• Considerable concrete mix design testing using both flexural beams and test cylinders as well as washed concrete gradations to confirm unreinforced slab design criteria.
