The Sectors We Work In

All levels of highway and railroad bridge evaluation services including:
+ Developing instrumentation and testing plans
+ Qualitative data review, finite element modeling & calibration
+ Recording responses to live loads & temperature variations
+ Accurate AASHTO Load Ratings (LRF/LRFD) for highway bridges
+ Accurate AREMA load ratings for design loads and heavier rolling stock
Bridge Deck Evaluation
Data we collect is analyzed to report:
+ Concrete degradation, precursors to delamination, and concrete cover over the top rebar
+ Shallow delaminations
+ Delaminations and concrete degradation
+ Spalling, patching, and severe cracking
+ Electrochemical – probability of corrosion
We’ve adapted our techniques and hardware for use in evaluating hundreds of water control structures on major rivers for issues such as:
+ Tainter gate trunnion friction evaluation
+ Miter gate opening, closing, and hydraulic forces
+ Cable force balancing for lift gates
+ Welded connection inspection and evaluation
We can assist with an endless number of monitoring applications for civil structure construction phases which include:
+ QA/QC verification
+ Concrete curing temperatures
+ Measure cable forces to assist crews with field adjustments
+ Transportation loads while hauling structural members
Evaluation of all types of building issues including:
+ ASTM floor & column load tests
+ Foundation settlements
+ Crack growth monitoring
+ Seismic movements
Several geotechnical data collection applications including:
+ Geomatic monitoring
- Automated Total Statistics
