“…Then, data is cleaned from noise, irrelevant information and clutter [31,203] and often decimated to improve computing time. Data captured with other techniques is processed according to its data format, the required functionality and the object recognition method [25,70,110,130,194]. Applied to fulfill maintenance or deconstruction functionality requirements of complex structures, data processing might overrun reasonable computing times due to increased LoD, high data volumes or limited computing capacity of mobile devices.…”

“…Manual techniques capture mostly spatial and other component-related information. Few approaches focus on other techniques like tagging [110,111,193] or utilize preexisting building information [25,130,194] to gather additional information such as components' dimensions, materials, textures, functions, connections, positions or maintenance periods. RFID or barcode tags are rather installed in new buildings [7,70,195], because in existing buildings tagging is limited by installation effort (e.g.…”

While BIM processes are established for new buildings, the majority of existing buildings is not maintained, refurbished or deconstructed with BIM yet. Promising benefits of efficient resource management motivate research to overcome uncertainties of building condition and deficient documentation prevalent in existing buildings. Due to rapid developments in BIM research, involved stakeholders demand a state-of-the-art overview of BIM implementation and research in existing buildings. This paper presents a review of over recent 180 publications on the topic. Results show scare BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in BIM occurring in existing buildings. Despite fast developments and spreading standards, challenging research opportunities arise from process automation and BIM adaption to existing buildings' requirements.

This paper proposes a method to analyze the geometry and semantic information of 2D vector floor plans, and reconstruct the corresponding 3D building models automatically. First, the Shape-opening graph (SOG) is introduced to recognize Structural Components (SCs) and describe the relationships between SCs and openings which are architectural components separating spaces. A priority principle algorithm is developed to replace openings with wall equivalent lines for the purpose of later loop searching. Then, we present an odd-even-based edge breaking algorithm to preprocess wall lines in order to search loops directly and exactly. After that, all the interior-space contours, which are in fact rooms or aisles, and exterior boundary contour can be obtained. With the hierarchical component tree presented, the topological relations of the whole building can be obtained. Finally, 3D models can be generated after extruding loops to the wall height and cutting openings from the walls. A drawing with several floor plans can also be reconstructed to multi-floor building after aligning their dimensions. Moreover, the intermediate result after analyzing the 2D floor plan can be the input of other architectural software to generate 3D models.

There is an opportunity to significantly impact building energy efficiency through BIM-enabled, simulation-intensive, cost-effective renovation actions. One major hurdle however is the lack of 3D digital models for the majority of existing buildings. Cost-effective and widely applicable methods and tools are required for the reconstruction of 3D digital models from available information. In this scope, this paper presents ongoing research about the development of tools for semi-automated 3D building model generation from 2D scanned plans. More specifically, the paper focuses on the description of an innovative reconstruction process based on a combination of automated processing and punctual, softwareassisted, user intervention. The paper also gives an account of the experiments lead with a research prototype, tested on 90 real architectural floor plans. The results are encouraging and suggest that the mix of software-assistance and focused human intervention may be the best trade-off to upgrade the quality of the generated models and to achieve cost-effectiveness.
