creative engineering solutions for bridges and other complex structures

creative engineering solutions for complex structures

At Hewson Consulting, our company history is deeply rooted in the design of bridges around the world, but our civil, structural and geotechnical design expertise extends across multiple other infrastructure sectors.  You can explore our experience in these sectors below.

Our services

From initial feasibility through to construction and beyond, our service offering includes all critical phases of an infrastructure project’s lifecycle, turning complex challenges into elegant and  buildable solutions that support our clients’ sustainability goals. 

Feasibility study
Our senior engineers can provide a comprehensive preliminary assessment to evaluate whether a proposed project is viable from technical, economic, environmental, and practical perspectives.
Structural Assessment
We provide systematic evaluation of a structure's current condition, load-carrying capacity, and remaining service life. The assessment identifies any structural deficiencies, and evaluates compliance and risk factors. This forms the basis for informed asset management decisions and ensures continued safe operation of bridge infrastructure.
Design
Our design services cover the entire project life-cycle, from concept and preliminary design to detailed design, temporary works design, and the design of strengthening and refurbishment programmes.
BIM/Digital Twin
BIM methodologies are embedded in all our projects and create a shared digital environment to enhance collaboration and coordination. BIM allows our designers to quickly explore design alternatives and optimize structural efficiency, material usage, and constructability.
Construction engineering
Having worked closely with contractors on both permanent and temporary works design, construction engineering of bridges comes naturally to us, combining our analysis and engineering capability with hands-on understanding of buildable solutions and techniques.
Construction Supervision
Where required, we will oversee the construction process to ensure the structure is built according to the design intent, specifications, and quality standards. Throughout the process we maintain detailed records, conduct progress meetings, and provide certification that the completed works comply with the design requirements and relevant standards, ultimately ensuring the structure performs as intended over its lifetime.
Independent Checking
We provide expert third-party design review and verification services for transportation infrastructure projects. We conduct thorough technical assessments of designs, calculations, and documentation to ensure compliance with standards, identify potential issues, and mitigate risk before construction. We offer independent validation that gives clients, contractors, and stakeholders confidence in project quality and safety.
Inspection
We deliver comprehensive structural assessment and condition monitoring services for bridges and other transportation infrastructure. We conduct detailed visual inspections, structural evaluations, and safety assessments to identify defects, deterioration, and maintenance needs. We provide thorough reporting and recommendations that help asset owners maintain structural integrity, ensure public safety, and optimise maintenance planning and budgets.
Value Engineering
We optimise project outcomes by systematically analysing infrastructure designs to maximise value while maintaining quality and performance. We review design solutions, materials, and construction methods to identify cost-effective alternatives, reduce whole-life costs, and improve functionality. We deliver innovative recommendations that achieve project objectives more efficiently without compromising safety, durability, or operational requirements.
Technical advisor
We provide expert engineering guidance and strategic support throughout infrastructure projects. We offer independent technical counsel on design challenges, regulatory compliance, risk management, and construction issues. We serve as trusted advisors to clients, helping navigate complex technical decisions, resolve engineering problems, and ensure project success from concept through completion.
Expert witness/advice
Our most senior engineers provide authoritative expertise for legal proceedings and dispute resolution in transportation infrastructure matters. We offer independent technical analysis, expert testimony, and professional opinions on design adequacy, construction defects, compliance issues, and industry standards. We deliver clear, impartial assessments and credible expert evidence to support legal teams, arbitrators, and courts in complex engineering disputes.
Contract Documentation
We produce comprehensive technical specifications, drawings, and contract packages for transportation infrastructure projects. We prepare detailed tender documents, bills of quantities, and construction drawings that clearly define project requirements and minimise contractual risks. We ensure documentation is complete, compliant with standards, and provides contractors with the clarity needed for accurate pricing and successful project delivery.
