This research aims to provide a model to compress the schedule by selecting the optimal activities in terms of cost, time, quality and risk using TOPSIS method. The current research is applied in terms of results and its results can be used in the direction of developing project management techniques and moving towards the application of engineering techniques in improving the performance of organizations implementing construction and investment projects. A library is divided. The library method was used to collect information related to the subject literature and the background of the research, and the field method was used to collect information to investigate the research objectives. In this research, the data collection tool is a questionnaire. The statistical population of the research for the questionnaire included 5 construction experts from the private sector, among whom the questionnaire was distributed. In an optimization problem with balancing time, cost, quality and risk, the appropriate implementation methods for performing a set of activities of a project from the beginning to the end should be chosen in such a way that the factors of time, cost, quality and risk of the whole project implementation are optimized. In this research, TOPSIS algorithm was used to solve the problem.

By examining the conditions of construction projects and costs related to occupational health and safety incidents, it is determined that occupational hazards and the management of safety and health risks are one of the most important missions and responsibilities of the project management system. Therefore, this study aims to Occupational health and safety risk assessment was carried out in one of the shopping center construction projects in Tehran.This research is a descriptive-analytical study with a direct observation approach. The sample in this research was all project employees in the number of 80 samples, which were purposefully sampled and selected.The data were analyzed using the risk management form by the FMEA method.

In general, the start of a large-scale construction and industrial project requires the preparation and supply of several prerequisites at the management and plant in the higher levels. At the plant levels, these prerequisites are anticipated in the form of a work package called site mobilization, from the time of price proposal and contract conclusion, and it enters the implementation phase after the kick of meeting. This work package supports the project until the end of the provisional acceptance and sometimes the final acceptance (guarantee period) which is defined based on the needs, structure, nature and goals of each project. In the implementation phase, project management and support has been done through the system which has been defined in the site mobilization. It is obvious that any mistakes, lack of predictions, non-compliance with the requirements and needs of the project will cause a delay in the schedule, the cost of changes will increase and human resources will be under the pressure and etc.This research is based on the experience gained from implemented projects and previous studies to state the standardized method for the site mobilization phase of EPC contracts and industrial projects.

Nailing system did not work in Rudsar town ship and course of use the new methods for real choice of this subject for analyzing point of nailing for investigation of the Rudsar township mountain side. In this project by attention to geothecnic character have with “Mahab Ghods “ office, in investigation with using of USA Standards (FHWA), nailed slope systems on the clay with high plasticity (HC) by 10 meters height, with help of nails by 15 degree angle, with help of steel mesh dimension 20*20 cm (WWM 20*20 cm), with give portion from nail design. However at start with help of present tables in FHWA. The surface amount of nail section is 700 mm2, horizontal step is 1.5 m, vertical step is 0.75 m and safety factor (FS) is controlled and the end, analyzing by FLAC software. First amounts of design sorts by complete analyzing. The specification of soil tests is complete from particular weight, shear resistance and etc. groundwater level is controlled. The results have shown the positive and acceptable effects of the nailing method in different angles, the details of which are fully presented in paragraphs 1 to 9 of the conclusion section of this research.
