Shuttering Verification Checklist

Essential Checklist+

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

✓16 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.
  • Props are founded on a firm, level base plate or sole board, not directly on soft ground or an unsupported floor edge.
✓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.
  • Construction joints (if the pour must stop partway) are placed at a planned, structurally acceptable location, not wherever concrete happens to run out.
✓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.
  • Slab/beam soffit formwork and props supporting it are only fully removed once the concrete has reached the strength required to carry its own load plus construction loads above, not just the minimum wall/column striking time.

✓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.
  • Formwork material selected (timber, plywood, or steel panel) suits the number of reuse cycles planned, since undersized or worn material fails early and affects finish quality.
  • Chamfers, drip grooves, or architectural features required on the finished concrete are built into the formwork design, not added after striking.
✓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.
  • Formwork dimensions are re-measured against the drawing after erection, not just after the initial setting-out marks were made.
  • Kickers or starter formwork at the base of walls/columns are keyed or roughened to bond properly with the concrete poured against them later.
✓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.
  • Props are founded on a firm, level base plate or sole board, not directly on soft ground or an unsupported floor edge.
  • Guardrails and toe boards are provided at open edges of elevated formwork decks before the pour crew works on them.
✓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.
  • Vibration during the pour is applied without directly contacting the formwork face, since prolonged panel-vibrator contact can loosen joints and cause leakage.
  • Construction joints (if the pour must stop partway) are placed at a planned, structurally acceptable location, not wherever concrete happens to run out.
✓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.
  • Slab/beam soffit formwork and props supporting it are only fully removed once the concrete has reached the strength required to carry its own load plus construction loads above, not just the minimum wall/column striking time.
  • Striking sequence follows the formwork design (e.g. sides before soffit, or back-propping retained after main props removed) rather than an improvised order.
