NBI is at 60% surveyed and at nearly the same in terms of detailed design. In terms of build works started and finished, it is referenced that 180,000 of NBI's build works have either commenced or been completed. The difference between commenced and completed is obviously quite significant. I know it is an average but how long does it take to go from build work started to build work completed?
