CASE STUDY(MANAGEMENT OF TILL SCHOOL CONSTRUCTION)
The project is “Till School” in Till village, near Nablus. It is a multi story building of two stories , the area of each story equal 655 M2, with the additional area of a roof and canteen of an area equal to 27 M2 and 40 M2 respectively.
Main idea of research:
The research described how project management principles and techniques apply to the real world challenges. These techniques were used to MINIMIZE THE COST USING MANY ENGINEERING CONCEPTS.
THE SENARIO
This research is mainly done to manage the financial side in the project which is (Minimizing the Cost to the specified and agreed level).
A detailed cost study according to the inquired bill of quantity from the owner side
Owner
Engineering Consultants
Cost analysis was made
Owner
The overall project price is so much higher than the budget specified by the owner for the project completion
Manage this increment in the project price so that it fits the specified budget, within the specified duration.
Engineering Consultants
Original project price according to the original BOQ submitted from the owner = $ 774,000
Donner / Budget of the project = $ 710,000
Amount needed to be reduced= $ 64,000
METHODOLOGY
• Engineering aspects used in such case to reduce the overall project cost:
Value engineering.
Cost analysis for the structural elements and other elements.
detailed quantity surveying.
Re-design the main structural elements.
Reduction for not necessary areas.
Value engineering Value engineering definition: Value = How to increase the Value?1) By improving the performance. Value =
2)By decreasing the cost .
Value =
Implementation of value engineering
Following is an example of a reliable alternative used , that added a value to the project (by reducing the cost): Building stone:Two alternatives were suggested, but one was used:
1) The artificial building stone
2) The effaced face natural building stone
Original stone price =
Effaced face price = $5.5/M
Saved amount =$ 8900$ 7/M $ 72900
$ 64000
Implementation of value engineering
other items to which value engineering concept was successfully applied:
Tiles.
Steel doors.
aluminum windows.
Quantity Surveying
It was mentioned in the contract that the listed structural quantities are not accurately measured for competitive purposes, so quantity surveying was done to the main structural elements and it was found that the accurate quantities are less than the specified in the original BOQ.

Re-Design
Drop beams:
Total saved amount resulted from Re-Design = $ 3100

Area ReductionEliminating the store:
after study, the canteen store was eliminatedBecause there is adequate number of stores inside the building.
Savings due to the reduction in the canteen area.

Total saved amount from reduction of the canteen area= $ 6100
Schedule
The specified duration for completion of this project is 8 months .
According to primavera project planner results, it’s found that the time was not critical to implement the project.
Result: No Cost increment due to the specified project duration.
Conclusion
The following table summarizes the previous results:
Method Amount saved (USD) % of the total saved amount
Value Engineering 35,100 54 %
Quantity surveying 20,500 31.5 %
Re-design 3100 5 %
Area reduction 6,100 9.5 %
Total saved amount: (USD)
65,000 100 %
Recommendations
It is slightly recommended to search more about the application of the Value Engineering in the Engineering world.
