This document summarizes a presentation on parking structure maintenance. It discusses types of parking facilities including on-street, surface lots, and structures. It then covers typical structure materials like cast-in-place concrete, precast concrete, and structural steel. Common deficiencies in parking structures are also outlined such as ponding, failed joints, corrosion, cracks and more. The presentation emphasizes the importance of routine maintenance and timely restoration to reduce lifecycle costs and prevent reactive maintenance needs.
