• Map all building expansion joint locations: floor-to-floor, wall-to-wall, floor-to-wall, roof-to-wall, parking deck.
• Measure all joint widths; document existing cover assembly types and conditions.
• Review structural drawings for anticipated thermal, seismic, and live-load joint movements.

• Verify joint movement capacity: new system must accommodate total building movement without stress.
• Fire-rated joints: specify UL 2079 assembly matching required fire rating (1, 2, 3, or 4-hour).
• Seismic joints: design per ASCE 7 drift requirements; large movement systems required in seismic zones C–F.
• Traffic-bearing joints: specify vehicle load rating; nosing material for durability.

• Remove all existing joint covers, seals, gaskets, and nosings; clean substrate to bare concrete or masonry.
• Verify joint width matches system specification; adjust substrate if out of tolerance.
• Install new expansion joint system per manufacturer sequence.
• Fire-rated: install per UL-listed assembly instructions exactly.

• Verify installed system movement capacity matches design requirement.
• Water test horizontal and roof joints after installation; document results.
• Document all UL assembly numbers and installation photos at close-out.
