In a construction project, the unit labor cost for pouring concrete is $8.25 per cubic yard. One activity needs 125 cubic yard of concrete with the material cost of $60 per cubic yard of concrete. If a crew of 3 laborers is working normal 8-hour days and is paid $11/hr per worker, what is the activity’s approximate duration to the nearest integer

Question 5 a- Calculate the Duration and Total Cost of executing an underground RC tank that requires 800 m3 of concrete. The material cost is 1000 LE/m3. While the crew produces 60 m3/day: the number of laborers required are & carpenters at a wage 20 LE/hour and 3 laborers at a wage of 15 LE/hour. Assume an efficiency rate between (0.78 -0.93) and 8 working hours/day. b- If the Owner would like to reduce the activity duration to 10 days....

PROB #2: LearningCurve An activity to produce 100 units was planned for 40 working days of 8 hours each, for one 5 person crew at KD 10 per hour per person. Because of owner required acceleration, the contractor worked with 2 crews of 5 people each for 10 hour per day. The contractor had to pay KD 15 per hour per person for the overtime hours above 8 hr day. For this work, LP 85% ( for learning...

Use the information contained
below to compress one time unit per move using the least cost
method. Reduce the schedule until you reach the crash point of the
network. For each move identify what activity(ies) was crashed and
the adjusted total cost. (i.e., Calculate the minimum direct cost
when project is finished in 13 days, 12 days, 11 days, as well as
10 days.)
Note: Choose B instead of C
and E (equal costs) because it is usually smarter to...
