Means and Methods:

Projects included the installation and maintenance of site BMP’s, removal of universal and regulated wastes, abatement of asbestos and lead containing materials, demolition of structures, removal of underground utilities, site paving, site improvements, landscaping, backfill and compaction of utility trenches and foundations, as well as the onsite crushing of concrete and asphalt. Environmental remediation included the collection and disposal of universal and regulated wastes and the abatement of the interior and exterior of multiple structures. The site and structure demolition included the removal of 50 existing building structures totaling approximately 350,000 square feet, large quantities of underground utilities including miles of box culverts, storm drain, water, electrical duct banks and sewer lines throughout the 400-acre site. The project also included the removal of approximately six million square feet of 18” reinforced PCC concrete runway. Crushing of existing concrete to 2” minus base totaling 700,000 tons.

Challenges Faced:

The removal of the former airport runways was a unique and challenging aspect of this project due to vast square footage and thickness of the materials to be removed. AMPCO mobilized the nation’s largest guillotine stomper to fracture the concrete prior. This allowed the concrete to be removed and transported in manageable pieces. AMPCO stomped approximately 100,000 square feet of concrete runways per day and removed, loaded and relocated approximately 5,000 cubic yards of concrete materials daily to the designated onsite stockpile two miles away.
