Building Information Modelling (BIM) has been implemented by various Architecture, Engineering, Construction and Facilities Management (AEC/FM) firms in various countries due to inefficiencies in traditional construction project management practices. AEC/FM organization require to gauge the effectiveness of their BIM implementations for measuring their performance and enabling continuous improvement in BIM usage. Therefore, various BIM capability and maturity models are developed to help organizations achieving different BIM assessment purposes in AEC/FM industry. Due to the differences in applicability and focus of these models, they meet the demands of different BIM users. Thus, there is no commonly accepted and broadly used BIM capability assessment model in the AEC/FM industry. Furthermore, various types of facility information are generated and used by different stakeholders in different facility life cycle stages. Fragmented structure of construction projects require assessing BIM implementations based on specific processes. Nevertheless, the models in literature, do not enable process based BIM capability assessments. In this study, a reference model for assessing BIM capability of AEC/FM processes, which is called BIM-CAREM, is developed. BIM-CAREM is composed of two parts which are BIM Process Reference Model and BIM Measurement Framework. In the first part, key AEC/FM processes have been determined and defined in terms of process purpose and BIM outcomes. In the second part, BIM capability levels, associated BIM attributes, and a rating scale have been defined to be used during assessments. BIM-CAREM is developed based on the meta-model of ISO/IEC 33000 and later, an iterative development is performed through expert reviews and an exploratory case study. Finally, it is tested in four different firms using multiple case studies method. The results indicate that, BIM-CAREM is capable of covering key processes of facility life cycle and that BIM capability levels and BIM attributes are suitable for identifying BIM capabilities of different processes of organizations at various capability levels.

GERÇEK, Bilge; Tokdemir, Onur Behzat; İLAL, MUSTAFA EMRE; GÜNAYDIN, HÜSNÜ MURAT (2017-07-29)
Building Information Modeling (BIM) has been an emerging concept in architecture, engineering and construction (AEC) industry with a vast amount of promising benefits to construction projects. Implementation of BIM, however, requires comprehensive research and strategic planning. Industry-wide and organizational implementation guidelines and standards have been published around the world either to encourage organizations to adopt BIM or to present the minimum requirements to be followed where BIM implementa...
An Investigation of building information modeling maturity in turkish small-medium size enterprises architectural and engineering firms
Sarı, Ramazan; Pekeriçli, Mehmet Koray; Tanyer, Ali Murat; Department of Building Science in Architecture (2017)
Architecture, Engineering and Construction (AEC) industry experiences Building Information Modeling (BIM) transition process in all over the world. As the firms have advanced on BIM implementation, a necessity to benchmark the BIM performance has emerged. A couple of assessment tools were released for the sector to be used by organizations, individuals and governments to benchmark the BIM implementation maturity. The architecture and engineering firms in Turkey are also in the midst of BIM transition. Howev...
Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
Identifying the barriers of implementing lean construction principals in developing countries
Markazi Movaghar, Ehsan; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2016)
The construction industry is congested with many types of project management systems to control and manage construction projects but none of them really look in-depth to maximize the efficiency of the work flow and minimizing waste. The implementation of the lean construction principles into the local construction scene can improve the problems. However, lean construction is complex and can be risky if not properly managed. Lean construction efforts in some other countries have not been successful due to th...
Analysis of modeling effort and impact of different levels of detail in building information models
Leite, Fernanda; Akçamete Güngör, Aslı; Akinci, Burcu; Atasoy Özcan, Güzide; Kiziltas, Semiha (2011-08-01)
The main objectives of this paper are to evaluate the modeling effort associated with generating building information modeling (BIM) at different levels of detail (LoD) and the impact of LoD in a project in supporting mechanical, electrical and plumbing (MEP) design coordination. Results show an increase in total modeling time ranging from doubling the modeling effort to eleven folding it, when going from one LoD to another. When comparing modeling time per object, rates ranged from 0.2 (decreased modeling ...
