2. Introduction
The most important part of our project, the soul of it, is represented by integration between two giant aspects of our profession (civil engineering); Construction and Structural Design, and Project management and Quantity Surveying.

3. Project Management

4. Site Description Al-Makhfiah Secondary School

5. Site Description
Al-Makhfia Secondary Boys School located at Al-Makhfia area in the south of Nablus. The school consists of four floors; Basement, Ground, First and Second Floor, with total area of (1920 m2). It contains twelve different classrooms, scientific Lab. and Library, Computer Lab. In addition, Headmaster Room, Social worker Room, Teachers’ Room and Multipurpose Hall.

6. Site Description
The project owner is “The Palestinian National Authority- Ministry of Education” and it was funded by “The Islamic Bank” for one million dollar, and it took more than a year to be executed completely, the supervisor and the designer of the project was “Seraj Engineering Office”.

16. Design Check
Analysis of 3-D model for AL-Makhfiah Secondary School using SAP 14, ACI 318-8/IBC2009 code. 1. Design Criteria: Live Loads = 300kg/m² for classrooms. = 500kg/m² for labs. = 300kg/m² for stairs Super Imposed Dead Loads = 350 kg/m² Foundation Depth = 1.5 m Soil Bearing Capacity = 4kg/cm²

17. Using SAP, area of steel was checked at slab, column C2 and footing SF2-1, and we use in design load 71.6 ton to design footing SF2-1, but we use maximum load ton to design column C2.
