Render fence and front of house	Plasterer

Here are the conversations.
Carpenter
G'day, I'm Stan the carpenter for this job. I specialise in framing. It will take me two days to knock up and stand the wall framing, another day to plumb and brace the frame and probably another two days to complete the roof frame.
Plumber
Hi, my name is Robert and I'm available to complete your plumbing. I'll need a day to fit the gutters and downpipes, another day to rough in the gas and water after the roof tiler has finished, and then one more day after the wet area tiling is finished to fit out the taps and install the appliances.
Plasterer
Hello, Dominic here. I'm doing the solid plastering job on this place and I reckon it will take me about three days to render the front fence and it usually takes another three days to do the facade at the front of the house.

The correct answers are:
Task		Trade	Duration (days)
Erect wall and roof frames	Carpenter	5
Install gutters and downpipes	Plumber	3
Render fence and front of house	Plasterer	6
Once we know these durations we can put them into the PERT chart to help calculate the time for part of the construction process or the entire timeframe for the project.
