DURABILITY GUIDELINES FOR THE DESIGN, CONSTRUCTION, REPAIR AND MAINTENANCE OF PARKING STRUCTURES March 1994
FOREWORD
This project on Parking Structures Durability Guidelines was proposed
by Technology Development and Demonstration and was funded by
the Real Property Program and the Panel on Energy Research and
Development (PERD). This research was conducted in collaboration
with Halsall Associates Limited. The objective of this project
was to develop specific guidelines for the design, construction,
repair and maintenance of parking structures.
Every year, Public Works & Government Services Canada (PWGSC)
spends vast sums of money on the repair and maintenance of parking
structures. While it is generally accepted that a certain degree
of garage maintenance is inevitable, the design and construction
practices in past failed to provide adequate protection against
the increasing amounts of chloride based de-icing chemicals which
are being used in present in-service environments. The salts carried
into garages by cars migrate through the concrete to the steel
resulting in corrosion of the embedded steel components.
For the past five years, Technology, A&ES Services, Headquarters,
in conjunction with the Institute for Research in Construction
(IRC) at National Research Council Canada (NRC), have been monitoring
the performance of several parking garage structures and evaluating
various repair strategies in an attempt to develop techniques
for effective rehabilitation and maintenance of indoor parking
garages. Much of the knowledge gained from this multi-year research
study was used in the development of these guidelines. This document
will serve as a very useful tool for builders, operators and property
managers. However, it must be emphasized that decisions in design,
construction, repair and maintenance must be the responsibility
of qualified professionals. If proper procedures are followed,
the life of parking garages will be greatly enhanced.
