Knowledge – Tools – Service
PPI is a Consulting Engineering Firm that specializes in Geotechnical Engineering, Subsurface Drilling, Construction Materials Testing, Environmental Services, and Geophysical Testing Services.
PPI is committed to being a leader in the Industry, as demonstrated by our corporate focus on staff training and continuing education, and reinvestment in the Company’s Drilling, Geophysics, Field and Laboratory Testing, and Specialty Services resources.
Geotechnical Engineering
Geotechnical Engineering is the cornerstone of PPI’s business. PPI’s engineering staff is comprised of local and regional experts in the discipline, who are invested in the communities in which they live and work. PPI’s engineering staff has project experience with many of the most challenging and noteworthy Projects in the Region.
Subsurface Drilling
PPI’s Drilling Services Department includes ten (10) drill rigs, extensive tooling and support equipment, and numerous experienced Lead Drill Operators. PPI’s Project Management staff is skilled at designing and executing subsurface investigation programs tailored to nearly any geologic setting and project type.
Construction Materials Testing
Construction Materials Testing is a critical component of quality Site Development and Building Construction Projects. Construction Materials Testing Services provide a Quality Control check for Contractors, and Quality Assurance for Project Owners and Design Engineers.
Laboratory Testing
PPI maintains extensive, certified laboratories for completion of soils, aggregate, concrete, and asphalt testing. If you have a Geotechnical Soils or Construction Materials Testing Need, PPI should be able to help.
Environmental Services
PPI offers a wide range of Environmental Services to Clients in the Public and Private Sectors.
PPI has completed hundreds of Phase I and Phase II Environmental Site Assessments (ESAs) in accordance with ASTM D 1527, ASTM E 1903, ASTM E 2247, the EPA’s AAI Rule, and the requirements of various government agencies. PPI has five (5) professional staff, all engineers or geologists, who have appreciable ESA experience and meet the EPA’s requirements for an Environmental Professional (EP).
Geophysical Services
While not as common as performing subsurface borings/soundings, Geophysical Testing uses the physical properties of materials and their surrounding environments for qualitative analysis, allowing us to evaluate (or “scan”) the subsurface conditions through various methods without the use of borings/soundings. In other words, geophysics can be used to get a glimpse of and evaluate the subsurface conditions or measure varying properties of the subsurface materials (such as soil electrical resistance for grounding grids).
Specialty Services
PPI has developed a variety of Specialty Services in response to the needs of our Clients. Specialty Services can typically be classified within a main department, such as Subsurface Drilling or Construction Materials Testing, but are discussed separately since they allow PPI to offer a unique capability or increased depth of expertise.
