Challenges
  • Zuvic Carr was selected by a municipal entity in Connecticut to analyze and design repairs for an open spandrel reinforced concrete arch bridge over a watercourse. The existing 180-foot long structure was designed and constructed in 1959.
Solutions
  • Reviewed historical documents and data, inspected the bridge using an under bridge mobile snooper, prepared Load Rating Calculations in order to evaluate current conditions.
  • Structural design included provision for the demolition of existing metal bridge rails containing lead-based paint, parapets, bluestone flagging sidewalks, precast concrete planks and mortar keys. New combination rails, parapets, sidewalks, concrete planks and mortar keys, pilasters, and shear slab were designed. Sub-structure repair details were provided for variable depth patch and epoxy injection crack repairs to pier bents.
  • Prepared conceptual plans for an under-bridge work platform and debris shield to protect the watercourse 100’ below.
  • Assisted MDC in obtaining a local wetland permit and coordinated with the CTDEEP Dam Safety Unit and Federal Energy Regulatory Commission.
  • Conceptual plans were prepared for an under-bridge work platform and debris shield to protect the watercourse 100 ft. below. A second Load Rating Analysis will be prepared to reflect the condition of the structure after completion of repairs.
