A manufacturer of wheels for railroad cars, Griffin Wheel is building a new plant in Tulsa, Oklahoma.  Located just west of 145th East Avenue on Tiger Switch Rd, this new facility will be capable of bringing in the raw material by rail car and exporting the finished product for distribution nation-wide.

The excavation for this project required Mass Rock Blasting for the building pad and associated roads and rail spurs for the facility and Trench Rock Blasting for the utility lines and massive grade beams and footings which will support the building. 

Eichleay Engineers  and Constructors, Pittsburgh, PA, is in charge of the design & construction of this facility.

Koester Contracting Corp, Evansville, IN, is the excavation contractor in charge of all site preparation work.

Harden & Associates Surveying and Mapping, PLLC, Tulsa, OK, are the onsite surveyors.

Griffin Wheel purchased 350 acres of property.  This land is located in a limestone bearing region with less than 2 feet of topsoil present over the entire site.  In order to dig the building area,   massive footing trenches, utilities and railroad spurs, blasting of the limestone was required.

Koester Contracting Corporation out Evansville, Indiana hired Dykon Blasting to drill and blast all rock for the project.   Over 250,000  square feet of rock has been blasted and 5000 lineal feet of trenches.   Most of these were shallow cuts and required over 12,000 holes to be drilled and blasted.
