Reinforcement and Embedded Services Inspection Before Concealment

Complete at a defined hold or witness visit before specified reinforcement, anchors, sleeves, boxes or other critical embedded items become concealed by printing, grouting or closing the wall. Inspect only the elements relevant to this visit and mark genuinely inapplicable checks N/A. Do not allow concealment where required engineering inspection or release is outstanding.

Inspector checks reinforcement and embedded conduits in a 3D printed concrete wall before concealment.

The checklist

Design and coordination

  1. Current approved reinforcement/MEP coordination drawings identify the elements to be inspected.
  2. The print file and intended layer/cavity arrangement accommodate the approved reinforcement and embeds.

Reinforcement and anchors

  1. Required reinforcing bars, anchors or connectors have the approved type, size and grade.
  2. Reinforcement positions, spacing, laps and cover/clearances satisfy the approved structural details.
  3. Starter bars, connection hardware and required supports are correctly located and secured.

Cavities and grout interfaces

  1. Required ducts and grout cavities remain accessible, unobstructed and dimensionally suitable.
  2. Any prescribed grout preparation/placement stage and inspection prerequisites are satisfied before covering.

MEP and openings

  1. Conduits, boxes, sleeves and penetrations are in the approved locations.
  2. Embedded services and supports do not conflict with reinforcement, structural connections or the print path.
  3. Required fire/water/air sealing and movement details are provided or identified for the correct follow-on stage.

Evidence and release

  1. Photos/measurements identify the wall, elevation or layer before the work is concealed.
  2. Critical deviations have been referred for designer/engineer disposition rather than field modification.
  3. Required pre-concealment hold/witness inspections and release authorization have been recorded.

At a glance

  • For a single pre-concealment inspection of reinforcement and embedded services in a printed wall.
  • Verify approved detail, position, stability, access, clearances and release evidence.
  • Structural and service acceptance depends on approved design details and project ITP.
