Verify the delivered unit against the opening ID, dimensions, operation, handing, glass, finish, and visible condition before removing the existing window. Confirm that the correct approval documents, anchors, sealants, flashing materials, shims, tools, lifting equipment, and temporary protection are available. Review the weather forecast and avoid exposing an opening without a workable dry-in plan.
Inside the building, protect floors, furniture, walls, occupants, and mechanical equipment from dust, glass, and debris. Outside, plan ladders, scaffolds, lifts, landscaping protection, pedestrian control, and safe glass handling. Condominiums and occupied buildings may add elevator reservations, working-hour limits, noise restrictions, and daily cleanup requirements.
