SERVICES

LAND SURVEYING

We are capable of performing both conventional type surveying, typically favored by construction crews, as well as unmanned aerial drone surveys. For many of our projects, we provide the only survey for the project, capturing hydraulic, structural, environmental, and construction data requirements. If preferred by the client, we establish the project control and survey baseline through physical control points that tie into geodetic coordinate systems. By performing the site survey and collecting all necessary data, our staff can tailor survey requirements for each individual project, eliminating any “data gaps” and minimizing project costs.

SUBSURFACE INVESTIGATIONS

We have in-house drilling services, but also subcontract drilling as needed for specialty access projects. Use of in-house staff provides increase safety. We offer several in-house drill rigs ranging from the truck mounted B-53 Mobile Drill to track mounted Geoprobe to a skid-steer mountable D-25. We can tailor our investigation to your project needs.

Some key services offered are Split Spoon and Shelby Tube Sampling, Rock Coring, Concrete Coring, Mineral Investigation, Borrow Pit Investigation, Well Monitoring, and All-Terrain Drilling Capabilities.

SITE CHARACTERIZATION

As part of project planning, we perform detailed desktop studies, utilizing published data to the extent practical. This leads to cost savings by not duplicating past efforts and by informing the upcoming investigation leading to more targeted investigations.

DESIGN SERVICES DURING CONSTRUCTION

We offer many different construction related services. We are familiar with various types of project delivery and experienced with specialty construction methods. APS GEO has a team of seasoned engineers with an extensive background in design-build construction. As such, we can leverage this experience to consider project constraints that can drive construction costs.

DESIGN

Our team stives to use the most innovative design approaches in service to our clients. Our focus is on continuing education and utilization of state-of-the-practice methods in our work. Focused interdisciplinary coordination leads to efficiencies on projects and increased value creation.
