We were asked to carry out an occupational assessment of a company’s headquarters. Using the best market practices with regard to the occupation of spaces and the legislation in force, we were able to analyze the existing and available space and assess whether it complied with the legislation. We analyzed various compartmentalizations of the space, namely the space made available for each worker, by floor of the building and the distance between each worker; free space; the existence of spaces for personal use, such as lockers; whether the dining areas were of an adequate size (according to m2 per x people); whether the support spaces guaranteed a good functioning; workplaces and passageways with adequate natural and/or artificial lighting; obstructed circulation and emergency routes; whether the toilets are the minimum size and adequate for the number of workers; the existence of access areas for disabled people and, finally, whether or not the parking lot is the minimum size. In addition to this analysis, we present a proposal for improving the workspaces to comply with good working practices in all the areas assessed.
