Shuttering Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓13 Inspection Points
✓5 Verification Categories
✓Formwork Design & Layout+
  • Formwork design (panel layout, support spacing, prop/tie spacing) is confirmed against the concrete pour pressure and pour rate expected, not assumed from a generic layout.
  • Single-sided vs double-sided shuttering decision matches the actual site condition (retained earth face vs free-standing element).
✓Erection & Alignment+
  • Formwork is plumb, level, and to the correct line and dimension before any concrete is poured — checked and rechecked, not assumed from initial setting out.
  • All panel joints are tight and sealed (e.g., with sealing tape or foam strip) to prevent grout/slurry leakage (honeycombing) at joints.
  • Release agent (form oil) is applied evenly to all contact faces before the first use and reapplied for reuse cycles.
  • Rebar cover blocks/spacers are in place and rebar is clear of the formwork face by the specified cover distance.
✓Safety & Propping+
  • Props, braces, and ties are rated for the expected concrete pour pressure and are installed per the formwork design, not improvised on site.
  • Working platforms and access for the pour crew are stable and comply with site safety requirements.
  • Formwork for elevated slabs/beams has adequate temporary propping to the floor below, confirmed for the load path down through each level.
✓Concrete Pour Checks+
  • Formwork is inspected immediately before the pour for cleanliness (free of debris, standing water, previous concrete laitance).
  • Pour rate and lift height are controlled per the formwork design to avoid exceeding the design pressure, particularly for tall walls and columns.
  • Formwork and props are monitored during the pour for any sign of movement, bulging, or leakage, with a stop-work trigger if observed.
✓Striking (De-shuttering) & Reuse+
  • Minimum striking (formwork removal) time has been confirmed against the concrete's actual strength development, not a fixed calendar assumption, especially in cold weather.

✓Formwork Design & Layout+
  • Formwork design (panel layout, support spacing, prop/tie spacing) is confirmed against the concrete pour pressure and pour rate expected, not assumed from a generic layout.
  • Sheet/panel dimensions and grade (shuttering plywood, steel panel, etc.) match the specified surface finish requirement.
  • Single-sided vs double-sided shuttering decision matches the actual site condition (retained earth face vs free-standing element).
  • Openings for services, rebar projections, and construction joints are marked on the formwork layout before erection.
✓Erection & Alignment+
  • Formwork is plumb, level, and to the correct line and dimension before any concrete is poured — checked and rechecked, not assumed from initial setting out.
  • All panel joints are tight and sealed (e.g., with sealing tape or foam strip) to prevent grout/slurry leakage (honeycombing) at joints.
  • Release agent (form oil) is applied evenly to all contact faces before the first use and reapplied for reuse cycles.
  • Rebar cover blocks/spacers are in place and rebar is clear of the formwork face by the specified cover distance.
✓Safety & Propping+
  • Props, braces, and ties are rated for the expected concrete pour pressure and are installed per the formwork design, not improvised on site.
  • Working platforms and access for the pour crew are stable and comply with site safety requirements.
  • Formwork for elevated slabs/beams has adequate temporary propping to the floor below, confirmed for the load path down through each level.
  • Excavation face (for single-sided retaining wall shuttering) is checked for stability and shored if required before formwork is placed against it.
✓Concrete Pour Checks+
  • Formwork is inspected immediately before the pour for cleanliness (free of debris, standing water, previous concrete laitance).
  • Pour rate and lift height are controlled per the formwork design to avoid exceeding the design pressure, particularly for tall walls and columns.
  • Formwork and props are monitored during the pour for any sign of movement, bulging, or leakage, with a stop-work trigger if observed.
✓Striking (De-shuttering) & Reuse+
  • Minimum striking (formwork removal) time has been confirmed against the concrete's actual strength development, not a fixed calendar assumption, especially in cold weather.
  • Formwork is struck carefully to avoid damaging arrises (corners) and the cured concrete surface.
  • Panels are cleaned, inspected for damage, and re-oiled promptly after each strike to maximise reuse cycles and finish quality on the next pour.
  • Damaged or warped panels are removed from the reuse cycle rather than continuing to use them, since they compromise the finish and dimensional accuracy of later pours.
