Youhavebeenaskedbyyourconstructionmanagertowritea
projectreportexplainingtheintendedactionyouintendto implement to
resolve some programme difficulties. The client requires the
project complete at the original time and as
thisclientisextremelyimportanttoyourcompany,yourCMhas agreed to
fully investigate the possibilities. Take into consideration the
following: i.AlltasksshownontheattachedA3programmeareon programme
up to 30th June.
ii.After30thJune,asignificantareaofunsuitableground conditions was
encountered.
iii.Thiswillresultinthefollowingincreasesintaskdurations

the original). Task 2.25 days Task 2.33 days Task 2.42 days Task
2.61 day Task 4.25 days Task 5.24 days Task 5.13 days Note the
following constraints i.Due to complicated details, 2.4 can only
overlap 2.3 by one day.
ii.AccessisnotavailableonSaturday5th,12thJulyand 2nd August.
(a)Quantify what impact each extension above has on the critical
path and suggest a suitable action.Acceptable actions include:
i.overlap tasks, ii.introduce another team,iii.use
contingency,iv.use float, v.work available Saturdays and any other
efficiencies deemed appropriate.Refer to tasks by their WBS code
and the duration in working days.(15 marks) PART A Semester 1, 2014

Answers: (a) Sample overlap solution, there will be solutions
involving, using Contingency, using Saturdays and any other
efficencies. Status date 30/6/14 TaskStatusProblemSolution Task 2.2
5 days This is on critical path and if left un resolved would
result in 5 days overall delay. As this task will now finish on the
4 July, to minimise damage to critical path overlap2.3 to start
before completion of 2.2. Start 2.3 on Weds 2 July, this will
minimise delay to two days Task 2.3 3 days This is on critical path
and if left un resolved would result in 3 days overall delay With
2.3 now starting on 2 July but being extended by 3 days the new
completion date for 2.3 is Weds 9 July. Task 2.4 2 days This is on
critical path and if left un resolved would result in 2days overall
delay Task 2.4 is able to start on 8 July and will finish on 16 Wed
JulyTask 2.6 1 day This is on critical path and if left un resolved
would result in 1days overall delay Task 2.6 is now 4 days long, by
overlapping with 2.4 and starting on 15July it will be complete on
18 July. By adding up all delays to date we have 11 days which
should take us to 14 July. We have finished 2.6 on 18, we have
recovered 7 days but still need to recover another 4 days between
now and completion .Solution overlap tasks 3.1,3.2,3.3,3.4 by one
day each will recover the 4 days to bring complete back to its
original date. Task 4.2 5 days This is non-critical so we can
absorb this extra time of 5 days from the available float Task 5.2
4 days This is non-critical so we can absorb this extra time of 4
days from the available float Task 5.13 days This is non critical
so we can absorb this extra time of 3 days from the available float
