The Adaptive P/E Center is a concrete tilt-up building constructed on a sloping site which was partially underlain by an old buried channel cut through very hard rock. Earth Systems conducted a geotechnical engineering investigation for the project development. Construction required extensive dewatering programs and special measures to control shallow spring water. During construction Earth Systems provided observation and testing during site development and foundation construction, as well as inspection and testing for structural concrete, shop and field structural welding, and glued laminated beam construction in accordance with DSA requirements. In addition, Earth Systems provided observation, testing and engineering consultation services for control of shallow subsurface water for the project.
