“…The scores are very good (5), good (4), medium (3), poor (2), very poor (1). Generally, their qualitative score is also classified based on a 50 score scale, as very good (41-50), good (31)(32)(33)(34)(35)(36)(37)(38)(39)(40), medium (21)(22)(23)(24)(25)(26)(27)(28)(29)(30), poor (11)(12)(13)(14)(15)(16)(17)(18)(19)(20), and very poor (0-10).

Success in infrastructure projects requires success in all phases of the project, including design, construction, and operation. One of the necessary actions for developing countries to construct their economic infrastructures, is implementing infrastructure plans. This industry should focus more on the construction process and utilizing creative tools and new concepts for construction development. The reason of it is because of delivering the project with certain quality, in time and with the given budget. Contractors should have new strategies for construction to optimize project completion, and constructability. Accordingly, constructability improvements have become the concern of construction industry practitioners. Considering constructability issues in the early stages of the project enhances identifying design limitations that prevent capabilities of contractors to take part in planning and improving project performance. The purpose of this study is identifying the prerequisites of constructability to resolve the current problems of projects, including inappropriate plans without implementability, poor decision making in design, and lack of sufficient implementation experience in the design engineering team. This study provides a list of prerequisites for constructability implementation in infrastructure projects. Accordingly, it identifies the prerequisites, using Systematic Literature Review (SLR) technique. The NVivo software is used to facilitate the qualitative analyses. 577Constructability is a project management technique, which examines construction logic from beginning to end, in order to identify obstacles, restrictions, and potentials. Using constructability in the initial stages of the project and attendance of contractors in the early stages result in improvement of project performance and consequently, reducing costs, time, wastes, delays, duplications, mistakes, and increasing quality of the project and coordination of its stakeholders [4].Therefore, constructability improvement should be considered as a part of the whole project lifecycle. Thus, paying attention of the construction industry to constructability and identifying its prerequisites can improve project performance. This is exactly what the present study is looking for. The next section reviews the existing literature to remove the research gap.This study at first reviews the previous studies related to this issue, including infrastructure projects, building projects, duplications, and constructability. Then, research methodology is described that is descriptive-analytic. Finally, considering the analysis and interpretation of data obtained from Systematic Literature Review, constructability prerequisites are categorized in 3 categories of specialized, technical, and content. In the following we will review the related literature

“…Lack of communication between designers and contractors often affects performance features, covertly or openly, which is somehow justified. Integrating constructability in the design process in the initial phases will reduce construction conflicts and thus project delivery will be more secure [12].…”

“…Constructability is one of the project management methods to evaluate the whole construction process. It is defined as a concept with relative, not absolute, value to increase optimization capacity of resources, such as workforce, time, cost, quality and working environment conditions (JadidAlEslami, Saghatforoush, & Ravasan, 2018).…”

“…Executive engineers usually have problems with designer engineers during construction process, due to lack of plan implement-ability, and/or contradictory and non-executive plans". [1] Construction stakeholders usually have problem with designers at the construction stage, due to lack of plan applicability or conflicting and non-executive plans [9]. The barriers to facilitate the constructability process have been identified up to now all over the world.…”

“…"Studies conducted during 1960 to 1970, indicate that the origin of many complex problems in the construction industry is due to lack of integration of knowledge and experience in the framework of design and construction." [1] Designers, through evaluating constructability studies, have always sought to reduce the existing gap between designers and builders. In practice, always a far distance is observed between the design and construction stages in order to achieve the desired project objectives [2].…”

In fact, constructability is facilitating the construction of a project through integrating knowledge and experience to achieve the overall and common objectives of the project in all stages of it, but practically there is still a significant gap between design, construction, and achieving the desired project objectives. Studies show that separating the design and construction processes and lack of presence of the contractor in the design stage, prevent the effective use of experiences and specialty of the contractor to improve and develop design processes. This issue results in increasing project time and cost, poor relationships, and also increasing project waste and duplication. The barriers to implementing this concept can have major differences with each other in different locations all over the world, due to the unity of the executive conditions in various countries. This paper evaluates the existing practical barriers to implementation of constructability in the construction industry. A comprehensive literature review has been performed by the authors through using the Meta-Synthesis method and findings were used to form research assumptions. Three case studies of Mass Housing project (MHP) in Tehran were instigated. Outputs taken from nine interviews with different experts in this industry working in diverse areas, including owners, consultants and contractors are then ranked after theoretical saturation compared using the NVIVO Software and through pattern and descriptive analyses. The concept of constructability is focused on the early presence of contractors in the initial stages of the project. So that, through integrating knowledge and experience, problems due to lack of their presence in the early stages of the project can be reduced. Comparing the existing barriers to implementing constructability in Iran with those of the wider world, presents some effective solutions to facilitate the presence of the construction contractors in the early stages of projects.
