If you are planning something similar
Fix these early
Lift weight sets the splice. A 40 t piece needs the crane to be planned before the truss is detailed.
Camber under self-weight. Long trusses are pre-cambered and checked in the yard.
Supports on concrete. Bearing positions on the concrete blocks must be surveyed before the lift.
