An email from Troy in regards to my question about timing of jobs.......
"The slab is scheduled for pour this Friday. There will be a curing period after the pour and then we will move on with external drainage, fill removal. Looking to deliver frames just after the Easter break. Construction will go in waves in terms of progress. Some periods of construction will appear to move very quickly and other times may appear slower. We are governed by trade availability and material availability and on site construction issues. There may be a trade scheduled for a particular day and the work may only take an hour or two, however the next work cannot occur on the same day because i don't know what time the first required trade will arrive. Their timing will depend on their workload and which area they are in at the time.
You would have seen signs of this at this stage of construction. There have been days when no one is there due to pending material deliveries, internal drainage install and some other things. The concreter is aware of the pour date that we agreed on prior to starting the work and, at this stage, will have no problems hitting this target date. Hope this helps."
