Investigating the Impact of Project Management and Construction Management and Risk Management on Time and Cost and Project Execution Process (Case Study: Building Mass Construction)

in this paper discusse about the effect of three factors of project management and construction management and risk management on the time, cost and implementation process of projects in general and on a case-by-case basis with regard to building mass construction projects.

at the beginning and in the first part of the construction projects, construction, dam construction, tunnel construction, road construction, mass construction of buildings, high-rise construction were considered as options and based on 10 common criteria extracted for management. Project and construction management and risk management were ranked using the AHP method.

According to the results, dam-tunnel-road construction projects were ranked first to third, respectively. for the three options related to construction projects, respectively, mass-building projects - high-rise construction, and finally, ordinary buildings are in the first to third ranks in the group of construction projects. Accordingly, mass building projects had the highest weight and was more important among construction projects. for conducting a case study, building mass construction projects of high, medium and low importance were considered as options and ranked according to the same criteria. The results showed that low-importance mass production projects were in the first place, followed by high and medium importance projects in the second and third ranks,

respectivelyOriginality/Value: 

in the discussion of mass construction in the country, the best way is to build a building at a medium level.
