Early career (1958–1966) Sir Leslie Martin arranged a job for Fordham as a development engineer at Weatherfoil Heating Systems Ltd in 1958, where he worked until 1961. There he completed a wide variety of design and research work. He designed the metered fan convection heating for Harvey Court, Cambridge, and was named as the inventor when this was patented. While Weatherfoil gave him a generous introduction to the building industry, they wanted to promote him away from design and into representing the firm. By this time, he realised this direction included all of the building services: water supply, drainage, heating, ventilation, air conditioning, as well as electrical engineering and he wanted more time to develop his detailing skills. After meeting Sir
Philip Dowson through his future wife, Thalia Dyson, in 1961 he joined the Building Group (now
Arup Associates), a group that included architects and structural engineers from Ove Arup & Partners. Here Fordham had to get to grips with drawing the services in complete detail. It provided an integrated team, where discussions about services could be argued over the lunch table. Eventually, Fordham took on the public health and electrical services as well, so the services disciplines could be represented by just one person at meetings.
Establishing his own practice, Max Fordham LLP (1966–2022) After moonlighting while at Arup Associates, Fordham realised he had the opportunity to start his own practice. In September 1966 he left Arup, and started working from his bedroom. Here he pursued a new approach to engineering based on his own curiosity about how buildings work. He resisted being pigeonholed into the conventional boxes of engineering. He was always interested in the whole building, taking a creative but essentially practical approach to building services design, starting "with the edge of the universe as its boundary and then quickly narrowing down to the specific problem". Fordham did not like imposing his will on people, and developed a philosophical justification for reconstituting the practice as a democracy. Fordham died on 4 January 2022, at the age of 88.
Teaching Fordham was a visiting professor in building and design at the
University of Bath from 1990 until his death. and the Chairman of the Res Sub-Committee for Intelligent Façades for the Centre for Window & Cladding Technology in 1993. ==Notable projects==
