Pavement & Proving Ground Warehouse



Lebanon County, Private Client

Facility improvements are frequent at Fort Indiantown Gap, National Air Guard Training Facility. American Engineers Group, LLC (AEG) has been involved with the design and/or construction of over 15 of these structures, having provided varying combinations of design phase services including geotechnical, civil and environmental engineering, along with surveying and construction phase materials testing services. The Pavement and Proving Ground Warehouse was one facility where AEG provided almost all of these services.

Geotechnical Engineering services included initial site investigations, boring and test pit plan development, infiltration testing, coordination of geotechnical borings with full-time drill inspection, and soil and rock sampling and testing in AEG’s in-house AASHTO Materials Reference Laboratory (AMRL). AEG prepared a Geotechnical Engineering Report presenting the results of the subsurface investigation, laboratory testing, foundation design parameters, and earthwork recommendations, in compliance with the current International Building Code.

Civil and Environmental Engineering services included site plan development of existing and proposed conditions, design and construction phase NPDES permitting, development of Erosion & Sediment Pollution Control Plans (E&S) and Post-Construction Stormwater Management (PCSM) plans with narratives developed in conjunction with the county conservation district and the Pennsylvania Department of Environmental Protection (PADEP).

Surveying services were performed in the design phase and construction phase including topographic mapping, boring/test pit layout, construction stakeout, and as-built surveys.

Construction-phase Services were also provided by AEG. Borrow soils were laboratory tested to determine suitability by classification tests and moisture/density relationship by proctor test. AEG provided oversight and nuclear gauge compaction testing during the contractor’s earthwork operations, required to raise the building floor several feet. The bearing resistance of the excavated foundations were confirmed by dynamic cone penetrometer. Fluid concrete and grout sampling and testing was performed by AEG, along with associated laboratory unconfined compressive strength testing.
