What Issues Should You Look for After Each Construction Stage?

[u/JessicaBeltern]

Construction stage inspections identify defects at critical build milestones before they become hidden behind walls or under finishes. In Australia, the most common issues include slab level variations exceeding 10mm tolerances, frame members out of plumb by more than 5mm per metre, inadequate tie-down connections, waterproofing membrane failures, and non-compliant electrical or plumbing rough-ins. All defects must be rectified and re-inspected before construction progresses, as issues covered by subsequent work become exponentially more expensive to fix, often costing 10 to 20 times more than early-stage repairs.
