Creating smart construction contracts structure with the help of building information modelling

Erkenek, Avo Baran
The number of countries where BIM is mandatory to be used in projects is increasing day by day because of its data intensive structure. In addition to improving coordination and collaboration in the projects, BIM helps the stakeholders to visualize the project and make more accurate estimations at the preconstruction stage. In the process, some of the problems previously encountered are solved by adapting BIM system into the project but there are still many problems to be solved by using other technologies in the construction sector. Especially legal disputes which result from uncertainty in contract terms and disagreements in delivery and payment processes can be solved by automatizing the payment process and eliminating the intervention of human beings within the progress. Smart contracts can execute the terms of contracts with the project information through BIM and computer codes embedded in the blockchain system. In this study, a sample workflow model to combine smart contracts and BIM models is proposed by combining the information gathered from the literature on this subject and the results of research conducted with experts. Each component and step of the proposed workflow was explained in detail with their alternatives. The parameters and details needed from BIM models for its efficient implementation were determined. Then, the pros and cons of the proposed workflow model and the usability of these technologies in the payment processes were evaluated, and the limitations of using these technologies were explained.


Adapting SPICE for Development of a Reference Model for Building Information Modeling-BIM-CAREM
Yılmaz, Gökçen ; Akçamete Güngör, Aslı; Demirös, Onur (2018-10-09)
Building Information Modelling (BIM) is highly adopted by Architecture, Engineering, Construction and Facilities Management (AEC/FM) companies around the world due to its benefits such as improving collaboration of stakeholders in projects. Effective implementation of BIM in organizations requires assessment of existing BIM performances of AEC/FM processes. We developed a reference model for BIM capability assessments based on the meta-model of the ISO/IEC 330xx (the most recent version of SPICE) family of ...
Comparison of European and USA Based Construction Contracts and Understanding the Cultural Differences in Contract Bodies
Sarı, Ramazan; Pekeriçli, Mehmet Koray; Tanyer, Ali Murat (2018-11-18)
After increase in efforts in science and technology during the 20th century, cultural memory that a nation or civilization take benefits on daily practices solidified as civil institutions and get started a standard way of agreements in between project participants. There are two initial implications and thus two different approaches of standard contracts published in USA and UK by American Institutes of Architects (AIA) and Institution of Civil Engineers (ICE). Architecture, Engineering and Construction (A...
An Approach to Determine Exchange Information Requirements(EIR) for Metro Projects in Turkey
Doğu, Defne; Kaş, Serhat; Akçamete Güngör, Aslı (2020-11-14)
The paper represents a framework that can be followed while adopting Exchange Information Requirements for metro projects in Turkey. In contrast to the universal trend of implementing Building Information Model initially to superstructure projects, Turkey brought an obligation of BIM use for the first time in a metro project. Since 2014, metro projects tendered in Turkey, primarily in İstanbul, are BIM-mandated public projects. However, Employers have not yet developed organization-wide holistic standards t...
Modeling highway projects: The need for Highway Information Modeling (HIM) guideline and information exchange
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 ...
An investigation of legal aspects of BIM in construction contracts
Kaya, Fatih; Akçamete Güngör, Aslı; Birgönül, Mustafa Talat (null; 2019-04-17)
Building Information Modeling (BIM) has been adopted worldwide in recent years as a novel way of working that enables efficiency in the construction industry. Lately, numerous countries made it compulsory to utilize BIM in public construction projects. Similarly, BIM became a contractual requirement in some public infrastructure and Build-Operate-Transfer (BOT) projects in Turkey. However, in order to benefit from the advantages of BIM, some legal concerns such as intellectual property, liability, legal val...
