STRUCTURES

Static analysis: this part studies the loads and stresses.

Structural modeling: it is the process at which the physical structure is represented by mathematical model that can be analyzed and designed. So as become closer to reality the design will be safer and more economic.

Project Description The project is an unsymmetrical reinforced

concrete building that has setback shown in 3D model, each story has three spans in x-direction with span length of 7.5 meters except elevator opening span length that equals 6.5 meters, and three spans in y-direction with a span length of 7.5 meters

QUANTITY SURVEYING

  The process of quantities surveying is very

important in determining the level of quality required.

Studying of contract's items through specifying the risky quantities.

Therefore, quantity surveying will Minimize project risks which produce the higher quality.

The outcomes of accurate quantities were as follows:

1. Supply an accurate amount of resources.2. Minimize the contractor costs.3.Achieve high quality.4.Avoid disputes with contractor.5. Restrict the time needed to implement the

project.6. Limit the use of resources.

CONCLUSION

1.Safe design was obtained by this research.

2. High specifications could be obtained by several points:

* Qualified of consultant engineering offices.* Qualified contractors.

RECOMMENDATIONS1. Financial analysis to be done for the project

to specify the needed budget. 2. Provide qualified contractors within the

project to ensure the high quality.3. Qualified labors and good management to

ensure high performance of specifications.4. To all engineering offices we must

recommend that :a. must use a computer programs in analysis

and design.b. use all structural design principles.c. design buildings to resist earthquakes.
