Ensuring Transportation Infrastructure Safety

With more than 13 decades of infrastructure engineering history, H&H has extended the service life of hundreds of bridges and associated transportation-related assets. Due to the natural progression of aging infrastructure, H&H has developed a core group of engineers that specialize in the inspection, rehabilitation, repairs, and maintenance of existing structures and ancillary structures.

We remain at the forefront of innovation extending the healthy life of our infrastructure. We realize many owners are seeking system preservation as a key goal for their infrastructure planning moving forward. We will continue to deliver our quality engineering services toward this goal.

Our Rehabilitation Services include:
  • Preparation of plans to restore existing assets to their original condition
  • Preparation of plans to reconstruct historic bridges
  • Preparation of plans to repair localized deficiencies
  • Preparation of plans to increase the capacity of highway, railway, or structure to meet current criteria
  • Constructibility reviews of rehabilitation plans and methods
  • Seismic reviews and retrofit
  • Value engineering studies
