Staircase Concrete & Steel Verification Checklist

Essential Checklist+

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

✓13 Inspection Points
✓4 Verification Categories
✓Geometry Verification+
  • Total floor-to-floor height, riser, and tread used match the architectural drawing, not assumed round numbers.
  • Waist slab thickness and staircase width used are confirmed against the structural drawing.
  • Headroom above every step (measured vertically to the soffit of the flight or landing above) meets the minimum required clearance, not just checked at the bottom step.
  • Going and rise are uniform across the entire flight — no single step differs from the rest, which is a common trip hazard if the last riser is adjusted to make up level.
✓Concrete & Formwork+
  • Step (riser face) shuttering is rigid and properly propped from below along the full inclined length before pouring.
  • Waist slab thickness is checked at the underside formwork, not just at the top surface, since an out-of-level soffit changes the effective structural depth.
  • Props supporting the inclined flight are founded on solid ground or a properly supported floor below, not on loose fill or an unsupported span.
✓Reinforcement Verification+
  • Main bar diameter and spacing along the slope match the structural drawing, with correct concrete cover maintained.
  • Landing reinforcement (main and distribution), if applicable, is properly tied into the flight's reinforcement, not left as a separate unconnected mat.
  • Main bars are extended and anchored the required development length into the supporting beam or wall at both the top and bottom of the flight.
  • Extra top reinforcement at the junction between flight and landing (where the bending moment reverses) is provided per the drawing, not omitted.
✓Casting & Curing+
  • Staircase is cured (kept moist) for the applicable minimum period, and shuttering/props are not struck before adequate strength is reached.
  • Concrete is compacted carefully around the inclined reinforcement mat without letting it settle or slide down the slope before the mix sets.

✓Geometry Verification+
  • Total floor-to-floor height, riser, and tread used match the architectural drawing, not assumed round numbers.
  • Resulting step count and adjusted riser height are within a comfortable range (commonly cited 2×riser + tread between 500-700 mm) before casting begins.
  • Waist slab thickness and staircase width used are confirmed against the structural drawing.
  • Headroom above every step (measured vertically to the soffit of the flight or landing above) meets the minimum required clearance, not just checked at the bottom step.
  • Going and rise are uniform across the entire flight — no single step differs from the rest, which is a common trip hazard if the last riser is adjusted to make up level.
  • Mid-landing dimensions match the direction change required (quarter-turn, half-turn, or straight flight) as shown on the drawing, with adequate width for turning.
✓Concrete & Formwork+
  • Concrete mix ratio/grade matches the project specification for the exposure condition.
  • Step (riser face) shuttering is rigid and properly propped from below along the full inclined length before pouring.
  • Landing shuttering (soffit and edges), if applicable, is level and adequately propped.
  • Waist slab thickness is checked at the underside formwork, not just at the top surface, since an out-of-level soffit changes the effective structural depth.
  • Riser shutter boards are securely fixed to resist the outward push of wet concrete without bulging or shifting mid-pour.
  • Props supporting the inclined flight are founded on solid ground or a properly supported floor below, not on loose fill or an unsupported span.
✓Reinforcement Verification+
  • Main bar diameter and spacing along the slope match the structural drawing, with correct concrete cover maintained.
  • Distribution bars are placed perpendicular to main bars at the correct spacing across the width.
  • Landing reinforcement (main and distribution), if applicable, is properly tied into the flight's reinforcement, not left as a separate unconnected mat.
  • Main bars are extended and anchored the required development length into the supporting beam or wall at both the top and bottom of the flight.
  • Extra top reinforcement at the junction between flight and landing (where the bending moment reverses) is provided per the drawing, not omitted.
  • Cover blocks are placed on the underside of the inclined mat to maintain bottom cover consistently along the slope, not just at the ends.
✓Casting & Curing+
  • Concrete is poured in one continuous operation for the full flight to avoid a cold joint partway up the slope.
  • Step nosings are properly finished and protected from damage before curing is complete.
  • Staircase is cured (kept moist) for the applicable minimum period, and shuttering/props are not struck before adequate strength is reached.
  • Concrete is compacted carefully around the inclined reinforcement mat without letting it settle or slide down the slope before the mix sets.
  • Riser shutter boards are struck and step edges are checked before the concrete goes fully hard, so any nosing repair can still be done cleanly.
  • Landing props are left in place at least as long as the flight props, since the landing typically carries load from both adjoining flights.
✓Final Check+
  • All steps are level, uniform, and free of honeycombing or exposed reinforcement after formwork removal.
  • Handrail/baluster fixing points are confirmed before final finishing begins.
  • Total concrete and steel used is reconciled against this calculator's estimate before closing out the item in records.
  • Step going, rise, and nosing are re-measured with a straightedge and level across the full flight, not just visually inspected.
  • Anti-skid finish or nosing strips are applied before the staircase is opened to regular use, particularly on exposed or wet-prone flights.
  • Staircase is photographed and recorded before tiling, plastering, or handrail installation covers the finished concrete surface.
