Abstract

Heritage buildings are iconic and symbolize the backgrounds of a country in both historical and cultural contexts. It is significant for heritage buildings to be conserved and therefore, quantity surveyors are needed to estimate the costs of the conservation. However, estimation of heritage buildings conservation costs is tedious and different from conventional approach for new buildings. This is due to insufficient amount of data especially the as-built drawings which in most cases are unavailable and even if they are available, they are often outdated. Heritage Building Information Modelling (HBIM) platform with the utilization of 3D laser scanner provides a bridge to this issue. However, previous studies on HBIM focus mainly on the creation of as-built Building Information Modelling (BIM) model and very little is known about its potentials in enhancing the estimation of heritage building conservation works by the quantity surveyors. Therefore, this research seeks to demonstrate the potentials of HBIM with the utilization of 3D laser scanner in enhancing the estimation of heritage building conservation works by the quantity surveyors. To achieve the aim of this research, single case study approach is adopted, and a 150 years old heritage building is chosen as the case study. The findings reveal that HBIM with the utilization of 3D laser scanner can acquire 3D data which can be subsequently processed to create as-built BIM model that can be used for preparation of cost estimation. Essentially, this research corroborates that HBIM with the utilization of 3D laser scanner provides enhanced platform and processes for quantity surveyors in preparing cost estimation for conservation of heritage buildings.
