 The skill set will include matters such as computational fluid dynamics, heat transfer through two- and three-dimensional constructions, the behaviour of materials, manufacturing methodologies, structural engineering and logistics.Over time, the specialist skills necessary in this niche sector have surpassed the capabilities of architects, structural and mechanical engineers as buildings are designed with more complexity and with the introduction of Building Information Modelling (BIM).Building façades are considered to be one of the most expensive and potentially the highest risk element of any major project.
