Why modular column systems live or die on base-plate grouting.
Tolerance stacks upward
A 4mm base error becomes a 40mm façade problem twelve storeys later. Survey control at the plinth is the cheapest correction you will ever make.
Grout is structural
Non-shrink grout transfers axial load into the foundation. Under-filled pockets concentrate stress on the anchor bolts instead.
Rehearse the lift
A dry-run pick sequence cuts crane hours more reliably than a bigger crane does.
