Building Information Models (BIMs) are being used widely in the construction industry, and a quality check should be performed in order to ensure the integrity and reliability of the models. Quality concern starts with the initial steps in modeling and continues through at the end of the lifecycle of a project. BIMs generally contain some errors and mistakes and if not identified, might result in long review processes with the employers or cause issues during code compliance checks or construction. Since the quality requirements vary according to the projects and even the stakeholders within the same project, it is challenging to establish a standard quality check procedure. In order to focus on the quality of the models, custom procedures tailored according to the needs of the design teams should be prepared. Hence, there is a need to explore the BIM quality issues and develop formalisms to identify and eliminate them in time. Currently, there are no guidelines and formalisms to determine the overall quality level of a Building Information Model and propose Quality Assurance and Control procedures. In this study, design reviews from the employer are used to determine the items to be checked for satisfying a structural model's integrity. The design and model reviews are classified and analyzed to understand the existing issues, and a quality control mechanism, including a checklist, is proposed. This study contributes to a better understanding of BIM quality issues and proposes a BIM quality assurance and control formalism that can be tailored by practitioners and design teams.

Exploring quality issues in building information models via structural design reviews Candir, Esat; Atasoy Özcan, Güzide (2022-11-01) Building Information Models (BIMs) are being used widely in the construction industry. BIMs generally contain errors and mistakes, if not identified, might result in long review processes with the employers or cause issues during code compliance checks or construction. Since the quality requirements vary according to projects and even the stakeholders within the same project, it is challenging to establish a standard quality-check procedure. To focus on the model quality, custom procedures tailored accordin...
Safety risk assessment using analytic hierarchy process (AHP) during planning and budgeting of construction projects Aminbakhsh, Saman; Gunduz, Murat; Sönmez, Rifat (Elsevier BV, 2013-09-01) Introduction: The inherent and unique risks on construction projects quite often present key challenges to contractors. Health and safety risks are among the most significant risks in construction projects since the construction industry is characterized by a relatively high injury and death rate compared to other industries. In construction project management, safety risk assessment is an important step toward identifying potential hazards and evaluating the risks associated with the hazards. Adequate prio...
Improving sub-contractor selection process in construction projects: Web-based sub-contractor evaluation system (WEBSES) Arslan, Gokhan; Kivrak, Serkan; Birgönül, Mustafa Talat; Dikmen Toker, İrem (Elsevier BV, 2008-05-01) One of the most important phases in the construction industry (CI) is the bidding process. During the bidding process, selecting the most appropriate sub-contractors (SCs) for the relevant sub-works is highly critical for the overall project performance. In order to select the most appropriate SCs for the project and prepare the most realistic and accurate bid proposal, general contractors (GCs) have to know all financial, technical and general information about these SCs. Within this context, GCs should co...
Optimization Of Product Design Through Quality Function Deployment And Analytical Hierarchy Process: Case Study Of A Ceramic Washbasin Erkarslan, Önder; Yılmaz, Hande (Middle East Technical University, Faculty of Architecture, 2011) Quality Function deployment (QFD) is a useful method for optimizing products which can be applied during the design process as well as in the postproduction process for further developments and revisions. This paper aims at examining the applicability of QFD and Analytic Hierarchy Process (AHP) to incorporate customer expectations and design quality into the product through a case study on a ceramic washbasin (1). In the first phase of the study customer needs and satisfaction are surveyed based on the curr...
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 ...
