Core Responsibilities

Primary Functions

Perform comprehensive hands‑on visual and tactile inspections of bridges, culverts, and ancillary structures following NBIS, AASHTO, and client-specific inspection protocols, documenting all observed defects, deterioration mechanisms, and structural vulnerabilities with clear, prioritized recommendations.
Plan and execute routine, in-depth, fracture-critical, and underwater inspections for diverse structure types (steel, concrete, timber, masonry), coordinating access methods such as rope access, bucket trucks, scaffolding, barge operations, and confined-space entry while ensuring safety and minimizing traffic disruption.
Prepare clear, concise, and technically rigorous inspection reports that include defect descriptions, severity ratings, photographic evidence with annotated imagery, measured dimensions, approximate quantities, recommended repair actions, and prioritized timelines for remediation.
Use digital inspection tools and bridge management software (e.g., Pontis/BrM, AASHTOWare, InspectTech, HxGN) to enter inspection data in standardized formats, verify database integrity, and contribute to asset inventories and condition assessment databases used for funding and planning decisions.
Conduct or coordinate non‑destructive testing (NDT) techniques—such as ultrasonic testing (UT), magnetic particle testing (MT), dye penetrant, and hammer sounding—for accurate detection of hidden defects, fatigue cracking, delamination, and section loss in structural members.
Evaluate load-carrying capacity and perform preliminary load rating assessments, gather field data for structural analysis, and communicate critical load restrictions or temporary shoring needs to stakeholders to protect public safety.
Coordinate traffic control, lane closures, and temporary traffic management plans in collaboration with local agencies and contractors to provide safe working zones for inspections and minor emergency repairs.
Identify and flag immediate safety hazards (e.g., exposed reinforcement, large spalls, significant scour, compromised bearings) and issue urgent notifications and written advisories to owners, operations centers, and emergency response teams to initiate interim protective measures.
Inspect and assess substructure components, foundations, piling, abutments, wingwalls, and scour conditions using sonar, diving teams, or underwater video where required, and document scour risk and recommendations for mitigation.
Review historic inspection records, previous repair and rehabilitation documentation, as-built drawings, and construction specifications to develop an informed inspection strategy and detect recurrent issues or ineffective repairs.
Collaborate with in-house engineers and external consultants to scope repair designs, provide field verification for bid documents, and support construction oversight through clarifying inspection findings and acceptance criteria.
Conduct detailed condition surveys following extreme events (flooding, earthquakes, collisions, fires, severe storms) and prepare rapid damage assessment reports that inform emergency response and recovery prioritization.
Collect and maintain accurate field measurements, member dimensions, material properties, and coring/boring locations to support structural analysis, load rating, and rehabilitation design tasks performed by engineering teams.
Apply corrosion assessment techniques and materials knowledge to evaluate protective coatings, cathodic protection systems, drainage effectiveness, and water intrusion paths that accelerate deterioration and influence repair strategy.
Provide on-site training and mentoring for junior inspectors, contract technicians, and seasonal crews in inspection methodology, safety procedures, data capture standards, and effective photo documentation practices.
Participate in pre-inspection planning and safety briefings, prepare equipment and inspection kits, ensure calibration and maintenance of measuring tools and NDT devices, and manage logistics for multi-site inspection campaigns.
Liaise proactively with state DOTs, local municipalities, railroad owners, utilities, and contractors to schedule inspections, obtain permits, facilitate access agreements, and communicate findings and work scopes.
Maintain chain-of-custody and quality assurance controls for sampling, core extraction, and field testing; coordinate lab testing for material characterization and incorporate results into final inspection deliverables.
Track and report key performance indicators (KPIs) such as percentage of structures inspected on schedule, condition index distributions, and backlog of critical repairs to support agency performance reporting and funding requests.
Assist with bid preparation, scope definition, and cost estimating for inspection services and rehabilitation projects by translating observed field conditions into realistic repair scopes and quantities.
Ensure compliance with environmental and cultural resource constraints during inspection activities, including erosion control, hazardous materials handling, and coordination with environmental agencies when work could impact protected habitats or waterways.
Maintain professional documentation and records for legal and contractual purposes, respond to stakeholder inquiries, and prepare expert testimony or technical summaries as needed for disputes, permitting, or public meetings.

Secondary Functions

Support asset management and data analytics teams by delivering high-quality inspection datasets, GIS-linked photos, and metadata for prioritization, lifecycle modeling, and capital improvement programming.
Contribute to the development and continuous improvement of inspection procedures, checklists, and digital templates to increase consistency, data quality, and automated reporting capabilities.
Participate in traffic management planning for inspection operations and small-scale emergency repairs, ensuring minimal disruption and compliance with local permit conditions.
Assist engineering design teams by performing field verifications, measuring existing conditions, and clarifying site constraints ahead of rehabilitation or replacement projects.
Support procurement and contract administration by evaluating subcontractor work, reviewing inspection deliverables for completeness, and verifying corrective actions are completed to specification.
Help coordinate training programs and safety refreshers for inspection crews, including NBIS updates, NDT certifications, and fall protection/rope access refreshers.
Provide expert input into risk assessments and resilience planning, translating inspection observations into recommendations for adaptation and mitigation against climate impacts and increased loadings.
Aid communications and public outreach by preparing plain-language summaries, inspection highlights, and technical appendices for agency reports and stakeholder meetings.
Maintain emergency on-call availability for rapid inspections and initial damage assessments following incidents that threaten bridge safety or serviceability.
Participate in research or pilot projects to evaluate new inspection technologies (drones, LiDAR, photogrammetry, AI-assisted defect detection) and recommend scalable tools for the inspection program.
