OB/OD New North and South Pad Design
GCE was subcontracted to develop a design for two concrete pads that would be utilized in munitions testing operations for the critical activities that occur at the Open Burn Open Detonation (OB/OD) facility located at Yuma Proving Ground (YPG) in Yuma, Arizona. The project included a soils investigation and a 100 year Flood Plain/Flood Protection Analysis prior to design. Several unique design elements were incorporated into the design of the pad. Since burning activities were to be performed on the pad, GCE designed the pad to withstand heat in the range of 1800 degrees Fahrenheit. Through extensive research on various types of refractory materials, GCE designed a pad that had low thermal conductivity, high temperature stability, rigidity, and high strength to allow for machining and cutting, and high compressive strength to allow for H20 loading. The pad had to also be sized to capture splatter of ash and other materials resulting from the burning activities. In addition, since fuel spills or other chemical spills are possible, the pad was designed to have a slight gradient toward the center of the pad where a grate and concrete structure could capture spills and transport them through a double walled pipe to a concrete retention basin. Both the pad and concrete retention basin were designed with a HDPE liner to avoid subsurface contamination and comply with RCRA requirements. GCE’s innovative design met all operation and regulatory needs for YPG testing operations.
GCE prepared complete construction drawings, technical specifications, and an engineers estimate of cost totaling $1,000,000. Once construction of the pad begins, GCE will provide construction inspections, materials testing, and construction staking services.
