Advantage Engineers provided geotechnical engineering services to the architect (Crabtree Rohrbaugh & Associates) during the design and construction phases of the new Spring Grove Area Senior High School and associated athletic complex. The new high school measures approximately 300,000 SF in plan area and the stadium complex consists of an artificial turf field, home and visitor bleacher sections, locker rooms, and a field house.
The geotechnical engineering design services included the following:
- Detailed subsurface investigation
- Laboratory testing
- Final foundation design criteria development
- Construction recommendations
Our design services also included the development of a ground modification program (i.e. compaction grouting) to mitigate the risks associated with sinkhole development and formulation of alternative foundation systems to reduce the impact of differential settlement due to karst features on the proposed stadium complex.
Our construction phase services included full-time, on-site review of the following:
- Compaction grouting program
- Structural fill placement oversight
- Utility installation
- Construction of storm drainage features
- Foundation and slab construction
- Structural steel erection
- Paving elements
- Laboratory testing of construction materials including concrete, masonry, and grout specimens
Over 100 sets of concrete compressive strength test specimens were cast and tested for the project. Advantage Engineers also completed testing and inspections of the subgrade and subbase for all asphalt roadways and parking areas, as well as the subgrade and subbase materials associated with the artificial turf and synthetic track surfaces.
