Table Q5 shows the cost of works and the program for the construction of a building. The informations of the project are as the followings:

i. The gross profit margin is 10 % of the cost.

ii. Retention money is 5 %.

iii. Progress payment is on monthly basis and measurement will be made at the end of each month and the contractor receives the payment one (1) month later

iv. The contractor is given advance payment of RM 500,000 at the start of the project; the advance payment will be returned to the client through progress payment deduction starting from the end of third month to the end seventh month equally

5. The retention money is repaid 3 (three) months after the practical completion.

To simplify the calculation, you may assume that all costs must be met at the instant they are incurred. You may also assume that the monthly value and cost for each activity are equally distributed.

Activity	Duration		Predecessor		Cost of Work
	(Month)				(RM x 1000)
Start	0		-
A	2		Start		400
B	3		A(FS-1)		1200
C	4		B(FS-1)		1600
D	2		B(FS-1)		1600
E	3		C(FS-2)		600
F	2		D		500
G	1		E, F		600
Finish	0		G
