T.Y. Lin International (TYLI) provided engineering and construction administration and inspection services for the rehabilitation of the East End Parking Garage in Rochester, New York. The structure is a five-level, cast-in-place, post-tensioned concrete structure constructed in 1983, with a south addition constructed in 1991.

The garage provides parking for approximately 1,300 vehicles. Previous TYLI services included completing initial inspections of the facility; identifying major structural, waterproofing, and safety deficiencies; completing significant repairs; and developing a long-term maintenance plan.

Due to corrosion from a previous failure of the waterproofing system, several post-tensioning strands within the cast-in-place concrete one-way slab deck system had ruptured. With strand corrosion threatening the structural integrity of the structure, TYLI addressed the critical, long-term structural needs of the facility.

Project Highlights:

  • TYLI performed a 100% hands-on visual inspection of the structural and waterproofing components of the garage, as well as the mechanical and electrical systems, including power and lighting, revenue controls, plumbing systems, and fire protection systems.
  • Ground-penetrating radar was used in strategic locations to identify areas of concrete deterioration, and a delamination survey was conducted of the entire garage.
  • TYLI focused special attention on areas of concrete deterioration, delamination, and cracking as they relate to the post-tensioning system. The results of the current inspection were compared with past findings, reports, and surveys to develop the most comprehensive, long-term recommendations for maximizing the remaining life of the post-tensioned decks.
  • TYLI developed a repair implementation plan and provided preliminary and final design plans, specifications, and estimates.
  • Improvements included the installation of new revenue control equipment.
  • TYLI and the City of Rochester contracted with a local artist to create a mural on the wall of a newly constructed garage office. This mural serves as an extension of the public art found in this unique area, which is adjacent to the Eastman School of Music and at the heart of the Rochester Jazz Festival venue.
