Services
Bridge Design
We create detailed bridge construction plans using LEAP CONSPAN and RISA software. Our engineers comply with AASHTO standards and traffic load requirements for both highway and railway structures. Clients receive comprehensive documentation for permits, construction, and long-term maintenance planning.
Underwater Inspection
Certified divers perform underwater evaluations of bridge foundations and submerged components. We employ thermal imaging and non-destructive testing to assess structural integrity for federal and state agencies across Great Lakes waterways.
Emergency Services
24/7 mobilization team addresses sudden structural failures and load capacity reductions. We implement temporary shoring, traffic control measures, and permanent repair strategies for immediate safety restoration following incidents like truck collisions.
Non-Destructive Testing
Advanced testing methods including dye penetrant, mag particle, and infrared thermography identify structural weaknesses without damaging components. Our certified technicians perform these assessments during routine inspections and post-construction evaluations.
Scour Analysis
Hydraulic engineers analyze erosion patterns around bridge supports using HEC/RAS software. We provide Level I and II scour evaluations with countermeasure recommendations to prevent structural instability from stream bed degradation.
