This project involved construction of a new structure at Fort Indiantown Gap, National Air Guard Training Facility. AEG provided a number of design phase services including geotechnical, civil and environmental engineering, along with surveying and construction phase materials testing 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 published soil and geologic characteristics for the proposed building site, along with the results of the subsurface investigation, laboratory testing, and foundation design parameters including allowable bearing capacities, structure foundation and earthwork recommendations, in compliance with the current International Building Code.

Surveying services included design phase topographic mapping, boring and test pit layout. Construction phase surveying services included benchmark establishment, building layout, and grade confirmations.

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).

Construction-phase Services were also provided by AEG. Borrow soils were laboratory tested for suitability and moisture/density relationship by proctor test. The contractor’s earthwork operations were overseen during fill placement, required to raise the building floor several feet, including compaction testing by nuclear methods. 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.
