While constructing various structures in our beloved country, Iran is of a long history, and the fact that design engineers have been designing and implementing buildings of various levels importance, considering our beloved country's seismicity, attention towards details of instructional design has received a great emphasis. Architectural considerations, an increase of the building height, size of the project, implementation capabilities and conditions as well as many other cases cause the proposed question in today’s projects to be different from a common residential building. In this regard, it is necessary to investigate particular challenges presented in each project by designing group and possible solutions to be proposed, so as to implement the best option for the most appropriate functions. Sazan with a considerable background in designing numerous high structures have frequently succeeded in facing with these special circumstances, since in addition to the experience which is undoubtedly a necessity for structural design, it always has emphasized on research and full review of issues in line with the group’s technical progress. Moreover, Sazan designing group goes through an optimizing process in designing the structures which causes the designed structures, while being totally secure and observing all engineering principles, also take economic considerations.
Errors are integral part of any human activity and as providing a safe structure, is the main objective of structural engineering, structural control on a structure designed by a design team, is one of the subjects which is highly important due to increasing reliability of the result. Sazan group, having considerable experiences in designing senior structures, is quite familiar with the finer details of such structures and has carried out several big projects of structural control.
