Three-dimensional digitization has been widely used for the documentation of built heritage. This paper presents two different approaches to the three-dimensional documentation of historic buildings using active 3D Terrestrial Laser Scanning (TLS) devices and data integration from other heterogeneous sources. Both methods aim to produce accurate and complete 3D surveys by integrating data from other sources, such as historical photographs, conservation reports, and traditional drawings, to enable a geometric analysis of the buildings. The first approach aims for completeness and redundancy of geometric information. The second method focuses on rapidness and is suitable for situations where the building is not easily accessible. The two approaches are applied to the case studies of Diotti Palace in Milan and Uzbekistan Hotel in Tashkent, demonstrating the efficiency of the two different datasets for analyzing the built heritage. The paper compares these two approaches and highlights their advantages and drawbacks in terms of the reliability of the resulting data. The study shows how two different methodologies can be adopted in different scenarios to obtain a comprehensive database for reliable and in-depth analysis of historic buildings.

This paper discusses the impact of the advanced systems of architectural survey and modelling to the research on the Conservation Management Plan (CMP) for architectural heritage, particularly when such a tool is applied to the 20th century architectural heritage. The authors focus on a comparison between the Building Information Modelling (BIM) technology and the Geographic Information Systems (GIS). The Conservation Management Plan for the National Art Schools of Havana in Cuba is used as case study. Given the plurality of buildings and various levels of interest in such a context, conservation and management needs, the need to share the results with non-specialized stakeholders, the need to combine different scales of analysis and different typologies of materials, the results point out the advantages of a GIS platform. The conclusions open to further possibilities of integrating GIS and BIM to the specific task of effectively conserving and managing the 20th century architectural heritage. [ABSTRACT FROM AUTHOR]

This paper discusses the relationship between advanced geomatics and Conservation Management Plan (CMP), by deepening the case of a CMP dedicated to the conservation of the 20th century architectural heritage. A number of issues have already been discussed on how the advanced survey techniques contribute to the conservation field for the last decades (e.g. Laser Scanner, HDR, GIS, intelligence vs. abundance, B.I.M, VT/IM etc.). The authors analyse pros and cons of each technique with respect to the main purposes of a CMP: 1.knowledge, 2.value assessment, 3.data sharing and dissemination of results, 4.support for conservation and restoration activities, 5.support for the planned conservation of buildings / facility management over time. With respect to the research on the CMP for the National Art Schools of Havana, the conclusions focus on the need to share results to non-specialist stakeholders, and on the possibility to combine different scales of analysis and a plurality of buildings with various levels of interest and conservation needs.

This discussion paper deals with the task of preserving past geometrical surveys and keeping them in use. The continuous advancement in technology caused a quick ageing of both survey techniques and their outcomes. This may result into a predetermined expiration date after which they risk losing their quality and usefulness (hence the title «Best Before»). Facing this risk, this paper focuses on the unceasing relevance of past surveys both as a legacy in the history of technique and as a fundamental source of information on heritage buildings, and thus a support to the preservation activity. The present paper offers an overview of the most recent attempts of preserving and keeping in use the paper surveys of the past. [ABSTRACT FROM AUTHOR]
