Bridge Inspection
Our bridge inspection services include routine evaluations, in-depth structural analysis, and emergency assessments for state and federal agencies. We employ certified inspectors with decades of experience to identify safety risks and recommend rehabilitation solutions. Our team adheres to National Bridge Inspection Standards while utilizing advanced technologies for accurate condition assessments.
Structural Engineering
We provide comprehensive structural engineering solutions for transportation infrastructure, including bridge replacements and building systems. Our engineers specialize in load rating calculations and rehabilitation of aging structures. With licenses in multiple states, we deliver designs that meet evolving safety and environmental regulations while prioritizing cost-effectiveness.
Underwater Inspection
Our underwater inspection division performs submerged evaluations of bridge foundations and hydraulic structures. Certified divers use sonar mapping and tactile examination techniques to assess structural integrity. These inspections inform maintenance plans and emergency repair strategies for critical infrastructure in coastal and riverine environments.
Land Surveying
We offer precision land surveying for infrastructure projects, including topographic mapping and boundary determinations. Our surveyors utilize GPS and LiDAR technologies to create detailed site models. These data support engineering designs and construction documentation for transportation and development projects across multiple states.
