Process of matching work items between bim model and cost estimating software

Abstract

Abstract. This article is focused on the process of matching work items into an organized structure in order to semi-automatically identify work items and link them between BIModel and cost estimating software. Several sources are suggesting a computer aided cost estimation based on historical cost data, which is a desired method of cost estimation. However, it is only achievable, if cost data are collected in an organized way and if format of cost data is structured according with defined standards. Those standards can be internal standards of a company, or national, even international standards that clearly define the structure of work items. Since work items are generally named differently throughout various bills of quantities, it should be more suitable to mark and recognize work items by numbered codes that will be defined specifically for each and every work item. The question is, what level of detail of a particular work item should these numbered codes reflect. More specifically, should these numbered codes represent a general group of work items (such as concrete grade, steel grade, size of masonry), or should they represent a detailed representation of work items (such as diameter of reinforcement, type of plaster, etc.). It also states the possible benefits for various stakeholders (client, contractor, designer, architect) throughout the life cycle of a project. It is to support the good practice of BIM in AEC industry. A semi-automatic e-procurement process is presented on the basis of matching work items into an organized structure. This semi-automatic e-procurement process is presented from the main contractor's point of view, however, it also takes into consideration other project's stakeholders. The article takes into consideration two contractual relations, these are Design -Build contract and Design -Bid -Build contract.

Utilization of digitized Building Data and Information Models (BIM) in value estimation of building in rural areas

“…Some articles also deal with the topic of "5D" on general level (like [9], in context of quantity surveying) or in context of different project phases (like [10], dealing with architectural study), but they were not useful for the purpose of this research. Some articles deal with the systematic approach for using BIM in specific cost related processes ( [11] in terms of process modelling, [12] in terms of LCC), but such papers do not deal with the topic of value estimation of existing buildings in the operational phase of the project.…”

Building Information Modelling Implementation Model for Sustainable Building Projects in Developing Countries: A PLS-SEM Approach

“…Moreover, Eastman, Eastman, Teicholz, Sacks and Liston [25] stress the significance of BIM in fostering effective communication among project participants. Stransky and Dlask [63] believe that BIM can serve as a decision-making tool during project implementation, leading to better performance. The literature highlights the importance of BIM in facilitating contracts' intelligent automation and promoting collaboration among team members, as demonstrated by the studies conducted by [64,65].…”

Modelling the Impact of Building Information Modelling (BIM) Implementation Drivers and Awareness on Project Lifecycle

“…(2) process-digitalization-and economics-related; (3) sustainability-and efficiency-related; and (4) visualization-and productivity-related. Stransky and Dlask [67] suggested that BIM aids decision making during project execution and improves construction productivity. Similarly, Eastman, et al [55] asserted that BIM improves collaboration among project teams.…”
