Blockwork on high-rise coast sites: when the wall looks plumb but the core is hollow
The QS measured m². The clerk of works cored the lift shaft wall — voids where grout should have been. Rework on every floor above.
What m² rates do not show
Plumb face hides empty cores, cold joints at lintels, and mortar ratio changes batch to batch. On coastal towers, acoustic and fire requirements in shafts make grout integrity non-negotiable.
Workmanship failures masons know but tenders ignore
Partial core fill; lintels cast without bearing length; movement joints omitted; mortar too wet in humid weather — shrinkage cracks at stiffeners.
Supervision that catches it before the next floor
Random core checks in shafts; lintel templates; photo log per lift; hold before MEP chasing.
Quoting after method is agreed
State block type, grout policy, lintel allowance, and scaffold cycle per floor.
