The Lexington Parking Authority recently acquired four parking garages from the city of Lexington. Their Annex garage is a six story deck that incorporates a helix as an exit ramp. The garage is located in-between the County Clerk and State Police offices, providing parking to both entities. The garage services a few thousand people a day.
This project is part of a multiyear restoration of all their garages. Ram Construction Services was contracted to perform a complete restoration of the Annex garage and helix. The concrete restoration of the garage was quite extensive and required the deck to be temporarily closed until all work was completed. Three Quarters of the 2nd Level of the garage was located over occupied space, which required complex coordination to complete the work. There was a total of 40,000 square feet of concrete that needed to be restored on all levels of the garage. A galvanic anode system was placed in the concrete to ensure that any future deterioration in the garages support system would be mitigated. The original design of the garage incorporated a steel expansion joint system which failed and needed to be removed and a new entire garage expansions joint system placed. These new joints provided a watertight surface that the tenants below have never experienced. A waterproof coating was then installed on the drive and parking surfaces of the garage to inhibit any exposure to water and road salts.
The helix portion of the garage was a major issue during the restoration of the garage. Instead of repairing the deteriorated concrete the entire drive lane surface was removed and replaced. This was quite a feat for Ram Construction Services based on the engineering concerns that were present throughout the demolition. The logistical approach of the entire project made it a challenge that Ram Construction Services relished.
