South Garner High School (Garner, NC)
GeoTechnologies is providing engineering and construction materials testing services, as well as special inspections for the South Garner High School Project located in Wake County. The project includes 111 classrooms, an auditorium, main and auxiliary gyms, a cafeteria, a stadium, baseball and softball fields, tennis courts, and practice fields. Several segmental retaining walls are included in the project. The buildings are supported on shallow foundations in areas of deep fill and excavation. Geophysical testing was used to improve the seismic site class from that which was assigned using penetration test data. The improved site class resulted in significant construction cost savings to the County.
Heck-Andrews House (Raleigh, NC)
The Heck-Andrews house is a Second Empire style mansion constructed in 1870, following the end of the Civil War. The House is a three-story structure that includes a full basement and tower offering stunning views of the historic downtown area in which it is situated. The house is listed on the National Register of Historic Places and in the late 1980’s the State of North Carolina acquired controlling interest in the site and restoration of the exterior began. The North Carolina Association of Realtors acquired the site in 2016 and is in the process of beginning interior restoration. The structure will eventually serve as the offices for the NC Association of Realtors.
Part of the transition from residential occupation to assemblage use, results in an increase in the design floor loads. GeoTechnologies was retained by the restoration design team to assist in determining if the existing foundations could safely handle the increase in load. The basement foundation walls are comprised of granite stones, hand cut and mortared together.
After conducting an investigation that included completing soil test borings in the basement adjacent to the foundations, a decision was made to conduct a load test in the basement level, adjacent to one of the interior load supporting walls. The load test presented some unique challenges, not the least of which was working in a dark basement. The biggest challenge to overcome was determining the best way to load the test plate. The existing building could not be used for reaction due to the potential for damaging the fragile plaster that covered all walls of the structure. Eventually, several helical anchors were installed in the basement, a load frame constructed and the test was successfully completed. The test results proved that the subgrade soils could support the load increase. GeoTechnologies approach to “think outside the box” allowed the design team to proceed with the renovation plans.
