In the context of transforming traditional labour-intensive industries into the service economy in China, the reuse of industrial heritage as museums has become a trend, for example, along Shanghai waterfronts, gradually fuelling the continuation of urban memory, reshaping urban cultural identity and promoting the development of the waterfront economy. Additionally, the connotation of a museum is continually being expanded from an institution to a method, and the major function is gradually shifting from collection to display. Previous studies on Shanghai waterfront industrial heritage have mostly referred to cultural factors, but these factors are still mainly included in macroscale large waterfront projects or microscale single practical project analyses. Mesoscale typology discussions between the two are rare. Therefore, this paper examines eleven industrial heritage sites that have been repurposed as museums along Shanghai waterfronts to analyse the urban memory elements of industrial heritage and summarise three classes of memory interpretation strategies: translating memory information, renovating memory carriers, and relating memory clues. Finally, the advantages and disadvantages of the study cases are discussed separately, and the following corresponding recommendations are made: 1) further enrich and balance memory interpretation strategies; 2) enhance the rationality, service, and tolerance of the "exhibition + " mode; and 3) improve local laws and regulations related to the protection and utilisation of industrial heritage to provide references for similar reuse designs.

This paper presents a scientific examination of wall paintings at two nonmonastic sites in Gyantse, Tibet: Gazhi Lhakang, which is a family temple built in the mid-eighteenth century by local aristocrats, and the Lotso Residence, which was occupied by Nepalese merchants in the early twentieth century. Samples were analyzed with optical microscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy, Raman spectroscopy, and X-ray diffraction. Two phases of painting—an early phase and a late phase—were identified in Gazhi Lhakang, including three distinct types of mural stratigraphy. The earlier phase features an unusual technique known as "paperhanging", wherein the pigments were applied on a layer of Tibetan paper glued to the wall. The later phase at Gazhi Lhakang and the painting of the Lotso Residence feature a relatively simple wall treatment with fewer coating layers and no ground layer. A typical mixture of clay and sand was used for the coating layers, while the structure slightly varied from what has been described in the literature. The techniques of powder embossing, gilding, and gold outlining were adopted in both buildings. The metallic material found at Gazhi Lhakang is a gold-silver alloy, while copper was used as imitation gold at the Lotso Residence. Mineral pigments, such as azurite, malachite, orpiment, cinnabar, and iron oxide, were used for both phases of Gazhi Lhakang. Modern synthetic pigments, such as chrome yellow, emerald green, and synthetic ultramarine, were used for the Lotso Residence, indicating that it was painted after the mid-nineteenth century.

Building information modeling (BIM) has received significant research attention in the field of built heritage. As-built BIM refers to a BIM representation of the "as-is" conditions of built heritage at the time of a survey. Determining the level of development (LoD) is crucial for as-built BIM owing to its relevance to model effects and modeling efforts. This study addresses this issue from the viewpoint of a brick structure based on a case study of a fifteenth-century ruin in Nanjing, China. Three LoDs are proposed based on the combined use of a commercial platform and auxiliary tools: A host model linked with raster images composed using orthoimage and relief maps (LoD 1), an as-built volume with semantic skins (LoD 2), and a brick-by-brick model with custom industry foundation class parameters at local areas (LoD 3). The results reveal that LoD 1 caters to an efficient web-based workflow for brick-damage annotations; as-built dimensions can be extracted from LoD 2; and LoD 3 enables attributes, such as damage types, to be attached at the brick level. In future studies, the detection of brick shapes is expected to automate the process of as-built surface mapping. [ABSTRACT FROM AUTHOR]
