Urban growth and rapid planning and development for cities have pushed the construction industry tobecomea sector with optimization and automationopportunities Many practices were born from that demand of progress, like the use of different new materials and implementation of technologies, but one of the strategies that has grown is prefabricated construction, more specifically modular construction. Prefabricated construction is a process where the parts or components of any infrastructure have been already constructed off-site (Ng, 2006). In modular construction these parts are being separatedas repeatablebuilding components, also called modules, with slight but essential variations that are assembled in a plant and transported to the designated site for their stackingand installation.

This practice transforms the traditional onsite labour work into a manufacturing process, which has been considered a cleaner approach as it can improve construction productivity,decreasehealthand safety hazardsfor workers, labour demand, construction timeand mitigate construction waste(Enshassi, Walbridge, Jeffrey, & Haas, 2019). Overall, this provides a large cost savings framework for the project and a significant impact on future construction industrialization in the AEC industry. Despite all the benefits that this manufacturing approach has been implemented, there are still several inside sectors that can be optimized and improved by taking advantage of the controlled environment that modular constructionoffers. One of theintroduced challenges that can be mitigated in such an environment is the quality control of the dimensional variability in the module production. In modular projects, this variability aspect could compromise the entire building structure as it leads to bigger and cumulative dimensional changes at its on-site installation.
