Works are in a live operational, security-controlled airport — strict airside rules, FOD control, limited storage, required inductions, ASIC requirements, supervised VIC limits, and possible shutdown/rescheduling to suit operations

Existing MSSB has no spare capacity; if an electrical upgrade is required it must be included in your design and lump sum price

Principal-supplied reports and drawings are information only — you must verify site conditions and accept responsibility for design accuracy and investigations (GPR not completed)
