# BIM Application in Multi-Criteria Assessment of
## 2 Literature Review  
The implementation of BIM is used in different construction areas to make the right decisions [3; 4]. A BIM project based on multiple evaluation methods, such as structural models, architectural models, and sustainable evaluation [5; 6], facilitates the approach based on the concept of a digital twin of buildings, which provides digital representation of real buildings including all models and necessary data for production [7]. Digital twin technology has great potential to form a BIM system that enables digital construction through a building's entire life cycle [8]. In this paper, the main focus is on the use of a BIM structural project for brickwork facade design and production. Nevertheless, the production of construction elements is not yet linked in the BIM environment, as manufacturing construction products is a sequential process that involves numerous manual operations [9]. However, during the design stage of brickwork facade, the implementation of BIM could ensure cost savings, and some researchers have proven that BIM supports production from a model and ensures cost reduction [10]. BIM applications provide new possibilities to save costs [11] not only during the design stage [12; 13; 14] but also during the production stage [15]. Some examples are offsite production with minimum activities on site [16], which saves energy and material consumption, proving the benefits of BIM application during the production stage [17]. Another benefit of BIM is the application of scanning technologies, which increases the accuracy of construction details and improves cost savings [18]. BIM models that receive detailed information can provide a good information environment for assessing the quality of construction [19] and ensure the best results. BIM models include the data of building components and offer the possibility of tracking the supply chains of construction products and materials [20]. Due to the complex decisions on how to implement architectural brickwork facades and the progress of production technologies, there is an urgent need to improve production processes based on BIM models, together with innovative brickwork facade installation methods. This provides an opportunity for all stakeholders in the process [21] not only to design 3D products but also to manage them according to PLM (Product Lifecycle Management) methodology during the production stage. It is established that BIM and LCA (Life Cycle Assessment) provide better quantity calculations for further steps of a project [22; 23], but production modeling requires skilled stakeholders with design and construction competencies [24] as construction managers are more experienced in project management than in offsite production management, although the latest research shows the benefits of offsite production [10]. To summarize, BIM can be used to produce, manage, and share data of building structures, while GIS (Geographic Information System) can be used for the logistical aspect of a building project, including to collect, manage, and analyze data [19; 25]. With the development of BIM technologies for brickwork masonry facades, and due to the complexity of such projects, information needs to be quickly available and shared between the design and production stages. However, using BIM technologies in construction projects requires data during all implementation stages of such projects, such as planning [2; 26], design [7; 11], production [9; 24], construction [16; 27], maintenance [19], and reconstruction [28; 29], to make the right decisions. Various MCDM (multiple-criteria decision making) methods have been applied to solve different problems of the building life cycle stages [30; 31]. Decision making always faces certain challenges, and the impact of risk and uncertainty must be assessed.
