This work aims to apply a systematic methodology to the analysis and graphical recovery of the “artefact” of the first lock of the Canal de Castilla (“the forge of Alar del Rey”) located in the Canal de Castilla as it passes through the province of Palencia (Spain). The canal, a great engineering work that began in the 18th century, was declared an asset of cultural interest (BIC, for its acronym in Spanish) in 1991 and was included in the National Plan for Industrial Heritage. To analyze and to obtain graphic reconstruction proposals, six main activities were developed, following three phases (study of primary and complementary technological and historical sources, fieldwork, and digital reconstruction). The reconstruction proposals were evaluated using three criteria: artefact data, the number of similar artefacts, and the performance. The weights of these three criteria were obtained using the Best-Worst Method (BWM), and the reconstruction proposals were classified using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) under uncertain conditions. AutoCAD was used to obtain detailed artefact geometric documentation (plans and detail drawings of each element). The work carried out on the artefact has allowed the reconstruction of the missing machinery and its factory, establishing a proposal consistent with the technological solutions of the end of the eighteenth century as well as with the ironworks studied and with the documentary sources consulted, recovering the memory of an artefact that is about to be lost.

Desde el 2017 al 2020, dos asignaturas del Grado en Ingeniería en Diseño Industrial y Desarrollo de Producto de la Universidad de Valladolid, impartidas por arquitectos pertenecientes a dos departamentos diferentes de las escuelas de Arquitectura e Ingeniería, se han coordinado para participar en concursos de diseño como estrategia de innovación y aprendizaje multidisciplinar, empleando como base el aprendizaje colaborativo y otras acciones complementarias. Habiendo comprobado que la difusión de sus proyectos motiva a los alumnos considerablemente, en el último curso se ha querido impulsar este aspecto a través de una exposición con catálogo. Si bien la situación provocada por el COVID-19 ha llevado a introducir algunas variaciones en el planteamiento inicial, el horizonte de participar en el concurso y en una nueva exposición, ha mantenido el interés de alumnos y profesores, y los resultados han sido realmente fructíferos a nivel didáctico. From 2017 to 2020, two subjects of the Degree in Engineering in Industrial Design and Product Development of the University of Valladolid, taught by architects belonging to different departments of the Schools of Architecture and Engineering, have been coordinated to participate in design competitions as a strategy for innovation and multidisciplinary learning, using collaborative learning as a basis and other complementary actions. Having verified that the dissemination of their projects motivates students considerably, in the last year this issue has been promoted through an exhibition with a catalog. Although the situation caused by COVID-19 has led to the introduction of some variations in the initial approach, the horizon of participating in the contest and in a new exhibition has maintained the interest of students and teachers, and the the results have been really fruitful on a didactic level.
