For architectural heritage conservation that worth archiving, the digital way of archive and storage has become an alternative opportunity for them to be preserved. Although BIM is mostly oriented to current construction praxis, there have been some attempts to investigate its applicability in historic conservation projects. This paper will focus on the Taiwan traditional historic architecture. There are common problems during the restoration and maintenance during the restoration and maintenance: (1) recording and communicating geometric and non-geometric information, (2) integrating and managing the multiple phases of construction and (3) the structural damage that can be incurred during the dismantling process. This leads to less confidence in the quality of restoration and maintenance. This study considers the traditional wooden structures in Taiwan as a basis to discuss the issues faced during restoration and the gap in communication between designers and builders. Using new techniques, resources and the concept of BIM, a plugin is developed for guiding restoration. It serves as a BIM-based communication platform for designers and builders the presentation between different professional teams through digital technology assistance, enabling the real-time exchange of information to minimize any gaps that may exist between the designers’ information and that of the builders. This allows information related to the restoration to be more accurate and offers the assurance that the traditional architecture retains its original structure and value. The life cycle of a historic building can be prolonged if digitalization is introduced into the preservation of traditional buildings while contributing to architectural education and digital archives.
INTRODUCTION
The natures of two different engineering works lead to different management processes, steps and ideas-the process of constructing a new building starts from zero, and followed by the construction work based on design drawings from building plan to every details. As an existing building, the restoration work of a historic building starts from existing building plans and onsite investigations to the design drawings and construction works of restoration.
The early techniques for restoring traditional buildings were mainly contributed by craftsmen. As a result of the modifications of relevant regulations as well as the intervention of modern construction system, construction works now rely on specialization. The heritage of traditional restoration techniques may have been lost. Unfortunately 2D drawings can not present all the spatial information, such as hidden parts of the building. During the restoration construction phase, inadequate or incomplete information can result in communication problems occurring during the design and construction phases, thus making it difficult to ensure the quality of the restoration. So it is important that information related to any restoration be accurate and assurances provided that these traditional buildings retain their original structure and value.
In this article, guidance regarding how restoration should be done is given. The use of new techniques, resources and the concept of BIM is developed as a communication platform between designers and builders. It enables the real-time exchange of information to minimize any gaps that could have existed between the designers and those doing the construction.
LITERATURE REVIEW
The study of the Building Information Model (BIM) has been steadily developing over the past ten years with BIM technology being widely used in different ways. Most research has focused on using BIM technology for planning and designing new buildings but recently research has been extended to using this technology for the restoration of existing buildings and the conservation of Taiwan’s architectural heritage. However, the application of BIM for the conservation of historical buildings is still facing various challenges (Volk, Stengeland ＆ Schultmann, 2014). Most of these technologies focus on the 3D rebuilding of geometrical or surface models in the research on historical buildings. Little attention is paid on the particularity construction methods, and also less discussion on how to assist in interpretation.
MATERIALS AND METHODS
This article attempts to find suitable solutions to these problems during the restoration work through the development of the BIM-aided restoration guidance system. We called it the Conserve Compass (C-Compass) system and it includes Revit plugin and mobile Apps. The main purpose of the C-Compass system we developed here is to assist with communication and coordination between the design of the repairs and the construction work on site. The data are shared immediately and on a regular basis. Further, the data shared is extensive in order to minimize any construction error. Therefore, the historical buildings are accurately preserved.
RESULTS AND DISCUSSION
This research has discussed the restoration of Taiwan’s ubiquitous communication problems between designers and builders in the building industry. To do this, it has introduced new technology and the concept of BIM to integrate all the data related to restoration.During restoration, applications are introduced to improve the quality of construction. The development of a plug-in application showed the following results:
During the design phase, using BIM with both 3D visualization and captions, designers will not have to be on the construction site. Working through the cloud, they can instantly access the correction of restoration data.
During the construction phase, the application of BIM can dismantle a complex component and recompose it through a visual information model. At the same time, BIM can present it as a 3D model immediately, receiving feedback and a new design instantly.
In the final stage, the construction report is presented in dynamic form (geometric and non-geometric information), different restoration information is provided and collections used for users through BIM.
In the future development, we aim to try to convert design data into information, introduce the application of 4D/5D project management to pass on this knowledge to the next generation. In addition, the application of the Geographic Information System (GIS) and Augmented Reality (AR) will be added. Currently, BIM, PMSI and GIS seldom intersect with each other and are not in parallel use. Therefore these systems can be combined and inte-grated for management needs in whole life-cycles.
