Grade Beam 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
✓Design Confirmation+
  • Grade beam total run, cross-section (width × depth), and reinforcement are taken directly from the approved structural drawing, not estimated.
  • Grade beam layout ties every column/footing shown on the plinth plan — no run omitted or left as a gap.
  • Reinforcement detailing (top/bottom bar count, stirrup spacing) matches the specific zone of the drawing, not applied uniformly if the drawing specifies zone-by-zone variation.
  • Column starter bar/dowel positions are coordinated with the grade beam reinforcement layout before fixing begins, avoiding clashes.
✓Excavation & Formwork+
  • Trench/excavation for the grade beam is taken to the level and width shown on the drawing, with a firm, level base.
✓Reinforcement Verification+
  • Top and bottom bar diameter/count match the structural drawing, placed with correct concrete cover on all faces.
  • Stirrup diameter and spacing match the drawing, with closed loops properly hooked and tied throughout the run.
  • Lap length used matches the applicable code's requirement for the bar diameter and concrete grade, not an assumed default.
  • No splice is placed inside a zone the drawing specifically prohibits (e.g. directly under a column, a marked no-splice region).
✓Casting & Curing+
  • Concrete is properly compacted/vibrated around reinforcement without segregating the mix, given the grade beam's typically confined trench/formwork.
  • Grade beam is cured (kept moist) for the applicable minimum period before formwork is struck or the beam is loaded.
  • No load (including masonry wall construction) is placed on the grade beam before it has reached adequate strength.
✓Final Check+
  • Grade beam top surface is level and continuous along the full plinth line before wall construction begins above it.

✓Design Confirmation+
  • Grade beam total run, cross-section (width × depth), and reinforcement are taken directly from the approved structural drawing, not estimated.
  • Grade beam layout ties every column/footing shown on the plinth plan — no run omitted or left as a gap.
  • Reinforcement detailing (top/bottom bar count, stirrup spacing) matches the specific zone of the drawing, not applied uniformly if the drawing specifies zone-by-zone variation.
  • Column starter bar/dowel positions are coordinated with the grade beam reinforcement layout before fixing begins, avoiding clashes.
  • The BBS/schedule used for ordering is prepared from the latest approved drawing revision, with the revision number noted.
✓Excavation & Formwork+
  • Trench/excavation for the grade beam is taken to the level and width shown on the drawing, with a firm, level base.
  • PCC/blinding layer under the grade beam is poured to the specified thickness and cured before reinforcement is placed.
  • Side shuttering (where used) is level, properly supported, and leak-proof at joints before pouring.
  • Whether the grade beam is trench-cast (earth-formed sides) or panel-formed above ground is confirmed before ordering shuttering material.
✓Reinforcement Verification+
  • Top and bottom bar diameter/count match the structural drawing, placed with correct concrete cover on all faces.
  • Stirrup diameter and spacing match the drawing, with closed loops properly hooked and tied throughout the run.
  • Lap splice locations are staggered per the applicable code and structural drawing, not concentrated at the same cross-section across all bars.
  • Lap length used matches the applicable code's requirement for the bar diameter and concrete grade, not an assumed default.
  • Cover blocks/chairs are placed to maintain the specified cover throughout the pour, not just at the initial tying stage.
  • No splice is placed inside a zone the drawing specifically prohibits (e.g. directly under a column, a marked no-splice region).
✓Casting & Curing+
  • Concrete is poured in the sequence and joint locations specified for the run, avoiding an unplanned cold joint mid-span.
  • Concrete is properly compacted/vibrated around reinforcement without segregating the mix, given the grade beam's typically confined trench/formwork.
  • Grade beam is cured (kept moist) for the applicable minimum period before formwork is struck or the beam is loaded.
  • No load (including masonry wall construction) is placed on the grade beam before it has reached adequate strength.
✓Final Check+
  • Grade beam top surface is level and continuous along the full plinth line before wall construction begins above it.
  • No visible honeycombing, cracking, or exposed reinforcement on the finished grade beam surface.
  • Total concrete and steel used is reconciled against this calculator's estimate (or the project BBS) before closing out the item in records.
  • Completed grade beam is inspected and signed off by the site engineer, with a photographic record kept, before backfilling or wall construction covers it.
