Formwork & Shuttering Inspection Checklist Template

Q: When can side forms (walls and columns) be safely stripped?

Under ACI 347 and BS 5975, vertical forms for walls, columns, and beam sides can typically be stripped after 24 to 48 hours provided the concrete temperature has stayed above 10°C and concrete has attained sufficient strength to resist surface damage.

Q: What is the allowable plumb tolerance for structural formwork?

According to ACI 117, the maximum allowable deviation from plumb for columns, piers, and walls is 6mm (1/4 inch) in any 3 meters (10 feet) of height, with a maximum cumulative deviation of 25mm across the structure.

Q: How do you prevent water leakage through tie-rod holes in retaining walls?

For water-retaining and basement walls, use tie rods with cast-in central waterstop disks, or install heavy-duty PVC sleeves with elastomeric sealing plugs and non-shrink waterproof crystalline grout post-stripping.

A Formwork & Shuttering Inspection Checklist provides civil QA/QC inspectors and temporary works coordinators with a systematic methodology to inspect formwork assemblies before placing concrete. It verifies dimensional accuracy, plumb tolerances, tie-rod cone waterstops, release agent application uniformity, chambered corners, and Falsework shoring load capacity. Rigorous formwork inspection prevents catastrophic blowouts, concrete bulging, grout leakage, and out-of-tolerance structural elements.

Applicable Standards & Codes

ACI 347: Guide to Formwork for Concrete

Common Site QA/QC Mistakes

Over-extending screw jacks beyond certified engineering calculations, compromising Falsework stability.
Spraying release agent after rebar has been installed, coating reinforcement bars in oil and destroying concrete bond strength.
Failing to install clean-out doors at the bottom of tall columns and walls, leaving tie-wire cuttings and debris trapped at the base.
Neglecting foam sealing tape along formwork joints, leading to grout leakage, honeycomb voids, and jagged fins.
Stripping vertical wall formwork early before concrete attains required self-supporting compressive strength.
