IV.Read this:

During building construction, several things went wrong so there are several changes to be made to the barchart in exercise 5. Here is a description of what happened: Excavation was delayed for two weeks because the excavator broke down. Therefore the machine drivers could not start work until week 3. As the steel erectors had to wait until the machine drivers hadcompleted their work, they were also delayed by two weeks. Consequently, the cladding fixers could not start until week 17. Bricks were in short supply during weeks 15 to 20 and this resulted in thebricklayers working three weeks longer than expected. So the plumbers and the roofing con­tractor started three weeks later. In week 30 the joiners went on strike which was settled after one week. However,this meant both the carpenters and the glaziers started one weeklate. The wrong paint was delivered to the decorators, which delayed them by one week, but by putting on extra men thebuilding was completed on schedule.

Now draw a new bar chart using the information in the passage.

V. Make a list of other things that could go wrong ona building site. Say when they might occur and how they could affect the time schedule.
