| Resumo: | During past century, construction industry is suffering from a poor productivity rate in comparison with the other industries. To solve this problem the concept of industrialization in construction was introduced which Modular construction is one of its methods with a not short history. However, during past decadehad changed its nature to be used for longer lifetime as permanent uses.The purpose of this study is to identify the possible advantages and investigate on common challenges related to modular construction industry in a project management perspective and intend to find adequate solution for them. The methodology of this study is a combination of quantitative and qualitative based approaches.A multi-criterion decision-making software (MIVES) was used to measure the functionality of advantages and their effect on final decision to use ether three modular alternatives (Steel, timber and concrete) or atraditional reinforced concrete method for building a residential project. The results showed that despite few poor performances in two environmental criteria (CO2 emission amount and Embodied energy used during construction) ,in general, all three modular alternatives had overcome traditional option in every requirement where prefabricated timber modular method became the most sustainable alternative. This result can confirm the positive effect of modular construction advantages and show its superior nature over conventional construction.In addition, a qualitative online survey form was sent to modular players to confirm the identified benefits, discussion about common challenges and receive recommendations and solutions to solve them. The responds were collected from five companies with the average of 20 years of experience in modular construction which illustrated that the advantages can be achieved in real projectsas wellas the literature review and study cases on decision making process identified.On the other hand, thereare challenges remainingwithout resolution such as Lack of partnership among participants of project, conflicts by local codding in use of automation, wrong perceptions of market etc.The possible solutions could be creating an international code for modular products, advertisement on potential advantages of modular method in public/market, updating the contract condition and most important of all improving the cooperation between scientific investigators and off-site industry to motivate and provide the researchers with more real data to prevent contrasts in hypothesises and find more innovative solutions.1 |
