Activity - Gantt charts
There is a PERT chart shown for the brick fence construction project. From node 1, the first task is 'Enquiries, orders'. Node 2 has three branches, one to 'Wait bricks' which leads to node 3 'Load bricks' then on to node 7. Also from node 2 is 'Clear site' then node 4, 'Dig trench' then node 5. The third task from node 2 is 'Order concrete' which also joins to node 5. The next task is 'Pour footings' then node 6, 'Footings curing' then node 7. The final section of the chart is 'Mix mortar & lay bricks' then node 8, 'Clean up' then the final nde number 9. Duration times for these are given in the table.
The Gantt chart is displayed as a table below. A 'W' indicates weekend days which are not usually work days.
Mark the dates for work to be done by placing crosses in the space under the appropriate date.
