AOG is Powered by Mobile Project Teams

Our special inspections team works on-site to obtain information about your property’s subsurface conditions. We frequently measure the thermal resistivity of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities. We monitor materials and workmanship and ensure compliance with approved plans, specs, building codes, ordinances, and more.

Dynamic Cone Penetrometer

Uses a 6.8 kg steel mass that falls 50.8 cm to strike an anvil and cause penetration of a 3.8 cm diameter cone (45-degree vertex angle) that is seated in the bottom of a hand augered hole. CDP can be used effectively in augered holes of depths 15-20 ft.

Compaction Testing

A procedure for calculating the in-place density and moisture of earthwork through the use of a nuclear gauge. This method may be used in conjunction with either a Standard or Modified Proctor Density Test for identifying the percent of Maximum Density.
