Roads & Bridges

Aging & deterioration of Infrastructure a challenge for Transportation officials

Highways, roads, bridges and viaducts are all critical components in the transportation system and owners, engineers, and transportation officials have an important role in making timely and appropriate decisions in addressing our aging infrastructure. Over the years SIMCO has developed a unique knowhow in infrastructure durability design engineering and has helped many transportation owners in the preservation of their most critical assets.

A tailored approach in construction, maintenance, and rehabilitation projects

SIMCO brings important knowledge, data and expertise for the development of sustainable transportation projects and focuses on helping clients improve the performance and durability of their assets.

SIMCO’s comprehensive and integrated approach provides our clients with solutions that are tailored to their specific needs and issues regarding their construction or maintenance and rehabilitation projects.

For over 25 years, SIMCO has assisted public and private industry clients in the assessment of the current condition of existing structures, in the evaluation of repair and rehabilitation strategies based on lifecycle cost analyses, and in designing concrete specifications for superior performance and optimum durability.

Existing Structures

For existing structures, SIMCO investigates the condition of the different concrete elements (e.g., deck, beams, piles, foundation, abutments, concrete pavement, etc.) in order to provide a comprehensive assessment of the structure’s residual service life and develop cost-effective maintenance and rehabilitation programs.

New construction projects

SIMCO will review and analyze durability design specifications, analyze exposure conditions in order to generate possible deterioration scenarios, review local material properties to evaluate service-life expectation based on various exposure conditions and will provide recommendations to reduce total lifecycle costs.

Adding innovation and the next generation technologies at every phase

SIMCO adds innovation and the next generation technologies at every phase of the project to assist owners in the management of the complete lifecycle of their concrete assets, from the initial concept through to the design, construction, maintenance and rehabilitation while helping them meet the most rigorous international standards.

SIMCO’s unique approach can be adapted to any type of concrete structure and any size of inventory, and covers all aspects of the asset management process. From inventory database population, inspection data collection and processing to identification of optimum repair scenarios and risk analyses, the result is a more reliable and cost-effective management of assets through streamlined processes.

Our Services

  • Evaluate and monitor a complete inventory of concrete assets
  • Quantify and compare the service life of design alternatives in accordance to lifecycle cost analyses
  • Elaborate performance-based design specifications
  • Validate mixture designs for specific applications and service-life requirements
  • Implement quality control protocols and procedures during construction
  • Create a comprehensive database of quantitative and qualitative data
  • Determine the physical and functional variables that affect performance and durability
  • Establish the viability of concrete repair and maintenance scenarios using predictive modeling
  • Analyze data gathered to optimize total lifecycle costs
