Abstract. At the present stage of development of the construction industry, steps to improve the efficiency of investment and construction projects can no longer be considered outside the context of construction information modeling technologies. Today, one of the main criteria for optimizing work on investment and construction projects is to reduce the time spent searching, working out and agreeing on spatial, financial, and temporal information about the construction object, therefore, the issue of the correct organization of information modeling of a construction site is quite relevant. In most cases, the design assignment is drawn up in the form given in Appendix B DBN A 2.2-2-2014 and is formal in nature. The presence of a design assignment, drawn up using the tools proposed below, reflects the thoroughness of the customer's elaboration of an investment and construction project, and reduces the risks of its implementation. The proposed methodology is based on three components of counter design, such as disaggregation, aggregation, and decomposition, from which its name – DAD –approach comes from. Allocation of structural elements in the structure of a building by disaggregation (analysis of alternative options) allows to create its model in the form of a hierarchical structure consisting of detailed and mutually synchronized parts - the configuration of the building. In accordance with the configuration of the construction site, hierarchical numbering is further reflected at all stages of design and in all its sections, incl. stamps of drawings and local estimates. This creates a unified system of interconnection and control of project sections. The creation of a construction site configuration in the form of a tree model with hierarchically numbered elements at the pre-design stage allows it to be applied at subsequent stages of the life cycle of a construction object in information modeling technologies. The use of the DAD – approach in counter-design is intended to increase the efficiency of the implementation of investment and construction projects.

One of the main problems the construction industry faces is the high cost and slow execution time due to inadequate planning, which results in poor use of human resources. A common solution for reducing time and costs is the adoption of prefabricated components (prefabs). This paper proposes a novel methodology for interdisciplinary man­agement of construction projects by integrating Building Information Modeling (BIM) and Lean Thinking to improve the production planning and control of pipe-rack modules in an industrial facility. The article first presents a literature review to assess the key synergies between BIM and Lean Thinking. These led to the development of a new integrated work methodology named Digital Obeya Room. This model focuses on the required workflows, the analysis of collected data, and the visual management of construction planning and control. A real-world empirical study in the Oil and Gas industry evaluated how the newly devised practices could improve prefabrication and preassembly planning. The pro­posed methodology was capable of reducing the welding-time in 8.7% related on global prefabrication average in con­struction projects from Fails Management Institute (FMI) prefabrication report survey 2017.

Variation order (VO) is one of the main issues faced by the construction industry in Jordan. Many researchers had investigated on the causes of VO and proposed procedures to minimize and control this issue; however, the VO is affecting the construction industry badly even at moment. Building Information Modeling (BIM) is a powerful management system that can make a significant difference in the project costs. However, BIM has not been examined as a tool to minimize the VO in Jordan. The main target of this study is to utilize BIM applications in reducing the effect of VO on the governmental projects in Jordan. In order to achieve this target, the researcher has designed a questionnaire to gather data related to VO causes and the BIM capability to solve this problem. The data collected from the questionnaires were analyzed statistically. The result from the analysis found that the consultant initiated the highest VO of 50% followed by the clients and the contractors of 20% and 10% unforeseen variation respectively. Moreover, it is found that BIM Design Applications, Facility Operations Simulation, Exploration Design Scenarios, BIM Design Detection and BIM Quantity Take-off and Cost Estimation were significantly capable of minimizing VO. The results show positive relationship with the application of BIM in minimizing VO in the construction industry in Jordan. © 2018. JASET, International Scholars and Researchers Association

Many construction projects suffer from poor design and from inconsistent time and cost management. This situation has led to rethinking of the industry’s performance and how it could be improved. Technology is breaking through design and management practices. Earned value management (EVM) enables better management of time and cost constraints. Building Information Modeling (BIM) is recognized to improve the planning and realization of a construction project. The present paper proposes an integrated time and cost management system (ITCMS), where an EVM platform is used in a virtual environment during the planning and construction phases of a project. The ITCMS enables early involvement and project integration plus thorough time and cost management. The system consists of four modules and 13 different processes. The ITCMS is beneficial at the design stage; construction professionals are able to synchronize the building model with time and cost parameters as well as optimize it through a clash detection process that results in budget and schedule compressions early on. The ITCMS is a useful tool for construction and engineering managers that strive to increase projects’ performance. The authors demonstrate in this paper the validity of using the ITCMS through an actual project.

Building Information

Design of green buildings involves specific processes compared to conventional construction projects that require participation of several disciplines. Having particular activities, functions, and physical aspects, green buildings impose their own difficulties during design. Building Information Modelling systems (BIM) use different software for virtual simulation of characteristics of projects, which promotes early detection of potential problems even before production of the intended design details. Implementing BIM technology in design stage, not only helps to minimize design problems, but also to shorten the stage itself. With this effect of BIM combined with sustainable practices and energy efficient technologies, design stage alone can be considered as a sustainable application of construction activities. Therefore, principles and requirements of green building certification systems can easily be performed for projects with capabilities of BIM technologies and tools. In this study, redesign of Yildiz Technical University, Faculty of Civil Engineering Building based on LEED certification system using BIM tools is presented. The project is prepared as part of a capstone project by senior civil engineering students. Design stages are planned to promote sustainability and qualify the requirements of LEED v3 BD+C (Schools). The main objective is to introduce the students to two major trends in construction industry (green buildings and BIM applications) and to create awareness of sustainable construction, green building certification systems and emerging technologies.

The Spanish construction industry has been subject to EU Directive 2014/24/UE. This directive allows member states to encourage, specify and even require the use of Building Information Modeling (BIM) in construction projects financed by EU public funds as of 2016. The QBIMInvest Project (supported by the Universidad Europea de Madrid) has conducted a survey, which is the subject of this article, on the implementation of Building Information Modeling in the Spanish AEC industry. This research uses 548 responses from a sample of Spanish AEC professionals to demonstrate that currently BIM tools are only being used in the design stage of residential buildings. There are few cases of them being applied in the construction, operation and maintenance stages or in other project types. On the other hand, professionals think that they will need at least 3 to 5 years to finish implementing BIM in projects.ResumenLa directiva UE 2014/24 invita a los Estados miembros a que fomenten, especifiquen y requieran el uso de Building Information Modeling (BIM) en los proyectos de construcción financiados con fondos públicos de la UE a partir de 2016.
