Services
Geotechnical Engineering
Our geotechnical engineering services analyze subsurface conditions to determine ground stability and load capacity. With in-house laboratory analysis and advanced software tools, we provide foundation design recommendations that optimize structural integrity while maintaining project timelines. Our engineers address challenges ranging from soil remediation to natural disaster recovery.
Construction Inspections
Certified inspectors perform comprehensive evaluations of construction projects, from foundation bearing capacity to structural steel installations. Our services include formwork verification, reinforcing steel placement checks, and post-pour concrete inspections to ensure compliance with building codes and specifications across commercial and residential sectors.
Materials Testing
AASHTO-accredited laboratory services test concrete, soil, asphalt, and masonry materials. We conduct slump tests, air entrainment analysis, and compressive strength evaluations to verify material quality. Field testing includes nuclear density gauge measurements for asphalt and concrete coring for structural verification.
Environmental Compliance
DEQ-certified inspectors ensure erosion control and stormwater system compliance. We implement Best Management Practices for construction sites and maintain stormwater facilities through annual inspections. Our services prevent regulatory violations while protecting water quality in developed areas.
Concrete Coring
Professional concrete coring services extract 1-8 inch diameter samples for quality testing. We perform non-destructive testing to locate rebar and post-tensioning cables, supporting plumbing/electrical installations and structural evaluations while maintaining slab integrity.
