Contribution of prefabricated constructions to reduce the risk of project management

Abstract

Project risk management focuses on key aspects of time, cost, human resources, safety and security, quality as well as environmental challenges, and the construction pattern is an important part of the problem. With the tremendous development in the field of construction and with the increasing need to complete the projects as quickly and as possible, the importance of the use of prefabrication technology to solve many of the problems facing the construction sector. Prefabricated concrete is no longer restricted to the industrial construction sector and is now used on a single scale in all construction areas such as housing and commercial buildings. The economic feasibility of the use of prefabricated concrete being in increasing the overall performance factors of the projects from reducing time, reducing cost and applying quality standards. With the development of additives for concrete mixtures, the quality of prefabricated concrete can be improved by improving the properties of concrete in terms of resistance, increasing thermal insulation and reducing stress applied on foundations through the use of foamed concrete and high resistance concrete. Improving the time of projects is important for the early use of facilities in order to expedite the recovery of the project's revenue value, use of prefabricated construction maybe reduce the time of implementation 10% or more. The ease of finishing works for prefabricated concrete blocks is quick and high quality due to the quality control inside the factory, despite some disadvantages related to the prefabricated concrete manufacturing in terms of the high cost of equipment and the need for large transport machineries. Its use with great economic feasibility contributes to the development of construction sectors.
