ABSTRACT:The aim of this paper is to explore the applications of photogrammetry in the field of archaeology of architecture. Specifically, to test possible advantages in adopting this tool for undertaking brick measurements for chronological dating of fired bricks historic structures. Mensiochronology analysis is a direct and non-destructive method providing an absolute dating of stratigraphic units. It is based on direct inspection and survey of bricks. Depending on the accessibility of the surface being studied, mensiochronology is suitable for vertical structures of limited height or relies on the availability of scaffolding and lifting equipment. There are several advantages in applying photogrammetry to brick measurement, among them: the possibility to undertake measurements of every kind of surface; the reduction of on-site survey time; the opportunity to repeat measurements off-site; the possibility to increase the number of measured elements in subsequent phases and by different operators. To explore the application of photogrammetry for mensiochronology three case studies are analyzed, testing the effectiveness of this tool on buildings displaying diverse features (e.g. handmade and industrial bricks) and dating back to different periods.

Abstract. The church of Santiago Apóstol of Kuñotambo is located in the southeast area of the Cusco province of Acomayo, containing remarkable interior mural paintings that contribute to the heritage value of the building and the area. The building was studied, conserved and seismically retrofitted as a model project for the Seismic Retrofitting Project (SRP), a collaborative project between the Getty Conservation Institute (GCI) and the Ministry of Culture of Peru in Cusco. Carleton Immersive Media Studio (CIMS) participated in the documentation of the decorated surfaces with an initial campaign in 2013, organized a series of workshops on documentation theory and practice with international experts and local professionals in 2017, and carried out a final recording after the conclusion of the site work in 2019. This last documentation phase provided a comprehensive documentation baseline and acquisition guidelines to plan the future long-term care of the decorated surfaces after their conservation. This paper presents the documentation carried out in 2019 and focuses on the three documentation scenarios proposed for the long-term preservation of decorated surfaces in the church: (1) Visual Documentation; (2) Digital Documentation; and (3) Comprehensive Digital Documentation. These different scenarios considered the particularly isolated location of the temple, the availability of equipment, the level of expertise in the different techniques proposed, and the frequency of future monitoring activities. Finally, the required tasks, necessary equipment, and potential challenges are presented for each of the documentation scenarios, with the objective being to offer a sustainable framework over time that serves the future Monitoring Plan for the heritage site.
