Fort Meade, Florida
Madrid Engineering Group, Inc. has been involved in an ongoing ten year site investigation and permitting for our client, WCA. The Fort Meade site is a WCA Construction Demolition and Debris disposal facility. Disposal cells involve a height of nearly 100 feet of fill. The project has involved extensive geotechnical characterization and foundation design, design of stormwater treatment systems, design and implementation of environmental monitoring, and regulatory permitting. The disposal area has grown from approximately 15 acres to more than 45 acres during the period. The project area is located north of Fort Meade, Florida.
The disposal facility is located on a former strip mine that has not been reclaimed. Because of this, the sediments on site are highly heterogeneous and provide some foundation design challenges in the form of localized highly plastic clays; moderately plastic silts, and very loose sands. The field investigations have consisted of an extensive network of standard penetration test (SPT) borings, vane shear testing, probing and standard rotary and auger borings. The field portions of the investigations have also included installation of numerous monitoring wells, pieziometers and surface water staff gauges. Laboratory testing has been done almost exclusively in-house, including percent moisture content, Atterberg Limits, grain size, organic content, specific gravity and strength tests including triaxial shear strength and uniaxial consolidation testing. Slope stability analyses for the foundation design of the various fill cells over the years were performed using G-slope analytical software. MEG has also been responsible for the semi-annual groundwater/surface water monitoring of the site in conformance with permit conditions. In addition, MEG has been responsible for construction monitoring and supervision of the various disposal cells as they were constructed.
