Q1

A company has taken a contract for landscaping of a plot of land. The job would require workers, supervisors, tractors, excavators, and a variety of trees, bushes and shrubs. Given below are necessary details of activities, their durations and labour requirements. Draw an initial loading chart with each activity scheduled at ES.

Activity	Days	Workers	Precedent
A	2	2
B	5	2
C	1	2	A
D	4	2	A
E	2	2	B, C

1. Can we complete the job with only 4 workers? Clearly illustrate your technique using a diagram and text.

EXERCISE 2

Activity	Weeks	Workers	Precedent
A	3	1	-
B	3	2	A
C	3	3	-
D	5	7	C
E	4	7	D
F	5	5	E
G	3	3	-
H	2	2	G

1. Draw a Gantt chart showing the resources required for each activity, durations, and the total float available
2. Develop a time-phased resource loading table
3. Develop a resource histogram before levelling
4. Identify any resource conflicts and begin to smooth the loading table using one or more heuristics
5. Develop a resource histogram after levelling.

Exercise 3

Consider a project with the following information:

Activity	Duration (Weeks)	Predecessors	Resource Hours Needed per Week	Total Resources Required
1	2	--	4P	8P
2	6	1	4P	24P
3	4	1	4P	16P
4	2	1	2P	4P
5	2	3	2P	4P
6	4	3	2P	8P
7	2	2,4,5,6	2P	4P

.

1. Draw a Gantt chart showing the resources required for each activity, durations, and the total float available

1. Identify the critical path and the project minimum duration
2. Complete theTime-Phased Resource Loading Table for this project, identifying the activity early start and late finish and slack from your network diagram.
3. Assume that the maximum workers per week available for the project are three. Identify any weeks with resource over commitments?
4. Resource level the loading table. Identify the activity that can be rescheduled and reconfigure the table to show this reallocation.

Describe your solution What is the project minimum duration?
