Geotechnical Engineering Services
Geotechnical engineering services typically consist of field exploration and subsurface investigations using test borings, test pits, hand augers, and/or geophysical methods (seismic refraction, electrical resistivity, micro-gravity, etc.) to identify and evaluate soil, bedrock, and groundwater conditions for new schools as well as additions/ improvements to existing schools.  Geotechnical design recommendations are generally provided for shallow and deep foundations, slabs, below-grade and retaining walls, utility and pavement improvements as well as site preparation/structural fill selection, placement, and compaction.  Unique or challenging site conditions (existing fill, marine clays, shallow bedrock, high groundwater, slopes, etc.) are additionally addressed to identify any special design/construction considerations and eliminate long-term performance problems.

Quality Control Services (Materials Testing and Inspection)
 Quality control services (construction inspection and materials testing) are provided by WDP’s certified inspectors and within WDP’s in-house, fully accredited, laboratory materials testing facility. Construction inspection and materials testing services typically consist of site preparation/structural fill placement and compaction for building pads, pavement areas, slopes, and utilities; foundation and slab bearing subgrade evaluations; concrete masonry (CMU) and structural steel construction including fireproofing; below-grade and retaining walls; asphalt and/or concrete pavement monitoring; laboratory materials testing of soil, concrete, CMU, grout, mortar, fireproofing, and asphalt.
