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 time) to 1.56 (increased modeling time). Based on the experiments done in MEP design coordination, it was observed that the automatic clash detection process using BIMs, with its consistently higher recall rate, provides a more complete identification of clashes, with the cost of false positives (low precision). This study showed that additional modeling effort can lead to more comprehensive analyses and better decision support during design and construction.

Ertaymaz, Uğurcan; Atasoy Özcan, Güzide (2019-06-01)
Building Information Modeling (BIM) is one of the latest trends in the construction sector and utilized for modeling, reviewing and analyzing building projects for the last two decades with benefits including visualization, planning, and estimation. BIM provides a well-organized and streamlined approach for building projects; however, its application for highway projects has been scarce. Progressing requirements, increasing number of stakeholders, integrated design solutions, expanding model uses and rapid ...

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...
BIM-CAREM: a reference model for building information modelling capability assessment
Yılmaz, Gökçen; Akçamete Güngör, Aslı; Department of Information Systems (2017)
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 achie...
A Method for Facilitating 4D Modeling by Automating Task Information Generation and Mapping
Altun, Murat; Akçamete Güngör, Aslı (2018-10-04)
4D modeling integrates 3D model with project time schedule to provide virtual simulation for identifying spatio-temporal problems earlier in construction projects. However, constructing a 4D model takes a significant amount of time and is prone to man-made errors due to its manual steps and repetitive nature. Therefore, in this study, a model based two-phase method is developed to facilitate linking 3D model with the schedule by automating the cumbersome steps. In the first phase, 4D Task IDs are created an...
The way architectural model as a new collaborative design environment talks with machines
Özkan, Sevda; Sorguç, Arzu; Department of Building Science in Architecture (2008)
The scope of this study is to illustrate the relationship between computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, and to show how architectural modeling should be positioned in the process of computer-aided design/computer-aided manufacturing (CAD/CAM) systems. The integration of computer aided technologies with architectural design is investigated in terms of design-production/fabrication interaction. The research has been based on a case study in which the CAD/CAM process from ...
