Commercial Countertop Installation-Day Checklist

Installation day should be assembly, fit, secure, seal, protect, and sign off. It should not be the first time anyone compares the top to the room.

Documents and identity

• Current approved shop drawings and release revision onsite.
• Installation scope, details, and manufacturer instructions available.
• Room numbers and top marks match labels.
• Seams, finished ends, cutouts, splashes, and supports identified.
• Open RFIs/holds reviewed; held work is not in the install batch.

Room readiness

• Cabinets installed, secured, level, and accepted for tops.
• Brackets, gables, blocking, and supports installed/verified.
• Walls and finishes at the required stage.
• Sink, faucet, equipment, and accessories onsite where needed.
• Plumbing/electrical conflicts cleared.
• Safe route, elevator, crew, lifting equipment, lighting, and work area available.
• Adjacent finished work protected.

ANSI/AWI 1236 general and structural requirements provide relevant installation coordination topics (AWI general requirements, AWI structural requirements). Use the contract edition and exact manufacturer instructions.

For solid-surface work, use the selected manufacturer’s fabrication and installation documents; Corian maintains current technical resources for its system (Corian documentation library). Other materials require their own source rather than a borrowed installation rule.

Top readiness

• Quantity and labels match the phase.
• Receiving exceptions resolved.
• Material/finish and orientation correct.
• Visible faces, edges, cutouts, and splashes inspected.
• Approved adhesives, fasteners, sealants, and cleaning materials available.
• Storage/temperature conditioning follows product guidance.

Stop-work conditions

Stop the affected top when:

• cabinet or wall differs from approved geometry;
• required support is missing;
• cutout item/template does not match;
• piece cannot reach or rotate into place safely;
• accessible clearance is compromised;
• damage or wrong material is discovered; or
• field modification would violate the approved assembly or safety plan.

When work stops, record the top mark, room, drawing requirement, observed condition, photographs, temporary protection, and decision owner. Move to unaffected work only when doing so does not scatter a matched set or create a new access problem.

Never trim first and ask later. The wall, cabinet, bracket, or equipment may be the condition that should change—not the finished top.

The storage guide protects the piece before this handoff. The punch-list guide organizes acceptance after installation.

End-of-day control

Record installed and held top marks, field conditions, photos, seams/joints completed, protection placed, missing pieces, damage, open trade work, and responsible next action. Do not leave an unlabeled loose top in a room and call the phase complete.
