Description
This guide is intended to assist parking structure owners, operators, and the consultants who advise them in developing preventive maintenance programs for parking structures. It presents typical maintenance concerns and suggests ways of addressing them.
The guide summarizes information regarding structural, operational, aesthetic, and routine maintenance for parking structures. A structural maintenance checklist of specific recommended tasks and references to other publications with information related to the structural maintenance of parking structures is included.
Keywords: concrete durability; condition appraisal; construction joints; contraction joints; corrosion; cracking; expansion joints; isolation joints; leakage; maintenance; membrane; parking structure; post-tensioning; precast; prestressed; ramp; scaling; sealant; sealer; snow removal; spalling.
