Automated Building Information Modeling System for Building Interior to Improve Productivity of BIM-based Quantity Take-Off

Abstract

Recently Building Information Modeling (BIM) has been widely used to manage building information throughout the project life-cycle more effectively and efficiently. Particularly in quantity take-off and estimation, BIM-based process is getting more and more attention, and even BIM-based quantity take-off at the most detailed level has been performed in several building projects in South Korea. The practitioners involved in those projects have pointed out that modeling rough and finish interior of a building occupies a big portion of time in the whole modeling process and the manual modeling for interior is error-prone, which could cause serious result, such as wrong cost estimation and disputes. To resolve the problem, this research proposes an automated modeling method that model a building interior automatically after selecting an interior method by a room or space basis. This research develops a interior modeling method and a system that can model various rough and finish interior components automatically at once after a user select the type of interior for a given space or room. To do so, this research identifies typical interior types of buildings and a house built in South Korea, and develops a mechanism that can support modeling both typical and non-typical types of interior by allowing the flexibility in selecting interior material and components and the order of construction process for the selected items. The automated modeling system for building interior has been preliminarily tested at a typical condominium building project and found that the system could improve dramatically the productivity of BIM-based quantity take-off and estimation process.

Building Information Modeling (BIM) for existing buildings — Literature review and future needs

“…Many reviewed publications cope with (semi-) automated modeling of building surfaces or components with respect to their geometrical representations. However, they do not regard component properties or semantic information yet [19,43,152,199,[203][204][205][206][207][208][209][210]216]. If non-geometric attributes like functional, relational, economical or semantic information of existing buildings are integrated into BIM, it is done interactively or semiautomated [130,[151][152][153].…”

Perspectives on Modelling BIM-enabled Estimating Practices

“…Amor, Jiang and Chen (2007) and Pučko, Šuman and Klanšek (2014) observe that these data are generally not organised in ways that meet estimators' requirements. Tiwari et al (2009) and suggest that overcoming this challenge is time-consuming; although others have pointed out that BIM-estimating improves estimators' productivity (Kim et al 2009). Nevertheless there is debate about whether perceived productivity improvements are a substitute for accuracy, feasibility and thoroughness (Ogunlana & Thorpe 1991).…”

Field Construction Management Application through Mobile BIM and Location Tracking Technology

“…With the development of BIM over the last decade, many researchers have studied its potential in various aspects: safety planning for temporary structures [8] and safety rule checking for fall related hazard were investigated, a prototype study for a large scale BIM model visualization was conducted [9], construction schedule optimization [10], and productivity study [11] were conducted. In addition, BIM has also been explored together with other resources to improve other aspects of construction.…”
