about us

Our Environmental Services focus largely on Phase I Environmental Assessments to facilitate our clients’ development projects.   This includes a site visit and records research.  We also provide Phase II services, when necessary.

Angle Engineering provides Special Inspection Services to residential, commercial, and public clients.  These services are defined in the International Building Code and are required by local agencies.  For most development projects, special inspections focus on Grading, Concrete, Masonry, and Structural Steel.

Angle Engineering performs Construction Materials Testing for soils, concrete and asphalt both in the field and in our laboratory.  Our in-house laboratory, accredited by AASHTO is where testing is performed for geotechnical analyses, special inspections, and general construction activities.
