Establish an expansion joint, drainage, and snow-load maintenance program for an open parking structure

Steps

1. Inventory all expansion joint systems (seals, joint headers, cover plates) and inspect for debris packing, seal tearing, or loss of adhesion, since clogged/failed joints allow water and deicing chloride intrusion into the structure below.
2. Verify deck drains and scuppers are unobstructed and slope-to-drain areas are functioning, since ponding water accelerates freeze-thaw and corrosion damage on open decks.
3. Confirm the structure's design ground snow load and any snow-storage/removal plan are consistent with current use, particularly if snow storage areas have shifted since original design.
4. Schedule joint reseal/replacement on a cycle informed by manufacturer service life and observed condition rather than waiting for visible failure, since joint maintenance is generally far cheaper than the structural repairs that result from long-term water intrusion.
5. Log all maintenance and repair activity with dates and locations, since this maintenance record becomes evidence of due diligence for both AHJ compliance filings and insurance underwriting.
