Practice

We evaluate, assess, and monitor the condition and health of existing and new infrastructure, including bridges, highways, airfields, marine structures, buildings, water/waste water treatment plants, power plants, pipelines, and other facilities, using innovative technologies that are rapid, reliable, and informative. Forensic investigations are part of our practice. We strive to use technologies that are least disruptive to facility operations and are least inconvenient to public. Based on our evaluation, assessment and monitoring, we also make recommendations for repair and rehabilitation.

Our practice includes the following services:

Construction QA/QC
Environmental Site Assessment
Subsurface Investigation
Structural Condition Evaluation
Non-Destructive Evaluation
Petrographic Analysis
Forensic Investigation

Testing and Evaluation Services

We provide a variety of testing and evaluation services, which include the following:

Concrete mixture proportioning and trial batches
Pre-placement observations (base preparation, formwork, joints, embedded items, reinforcing steel, cleanliness of placement equipment, weather conditions, consolidation)
Material property testing (slump, air content, temperature, unit weight, yield, compressive strength, rapid chloride permeability)
Post-placement observations (finishing, curing, form removal)
Crack, void and defect detection and measurement
Delamination surveys
Concrete cover measurements
Half-cell potential measurements
Rate of corrosion measurements
Carbonation depth measurements
Chemical analyses (chloride, sulfate, pH)
In-place strength measurements
Overlay bond testing
Weld inspection
Petrographic analysis
