Fazlur Rahman Khan was regarded as the Einstein of structural engineering, epitomising structural engineering achievement and creative collaborative effort between engineer and architect. Khan's central innovation in skyscraper design and construction was the idea of x-bracing and the tube and bundled tube structural systems for tall buildings. These innovations reduced loads, allowing for skyscrapers such as the Sears Tower in Chicago. Apart from several high-rise buildings, Khan planned and designed the Hajj Terminal at the International Airport Jeddah, Saudi Arabia, the U.S.

Halcrow is one of UK's leading consultancies, with a pedigree stretching back to 1868. The company's founder, Thomas Meik, worked extensively on port, maritime and railway projects in northern England and Scotland. During the first half of the 20th century, William Halcrow (later Sir William) established the firm as a pioneering force in other areas, notably tunnelling. Halcrow's first commissions outside the UK were undertaken in the 1890s. Halcrow specialises in the provision of planning, design and management services for infrastructure development worldwide.

Ian Liddell CBE, studied mechanical sciences (the precursor to engineering) at Cambridge University followed by a diploma in concrete structures at the Imperial College, London. One of the founding partners of Buro Happold, he retired in 2005, but continues to work for the practice as a consultant. He is a Royal Academy Visiting Professor of Engineering Design at the Cambridge University’s School of Engineering, a Fellow of the Royal Academy of Engineering, a Fellow of the Institution of Structural Engineers and a member of the Institution of Civil Engineers.

Professor Michael Dickson CBE, BA, MS, FREng, FIStructE, FICE, HonFRIBA, FRSA (b. 1944) is a structural engineer and a founding partner of Buro Happold. He is a Visiting Professor of Engineering Design at the University of Bath School of Architecture and Civil Engineering. He studied mechanical sciences (the precursor of engineering) at Cambridge University followed by Structural Engineering and Town Planning at Cornell University in the USA. He became the Chairman of Buro Happold in 1996 and held the post until April 2005, when he resigned from the partnership.

    Sir Ove Nyquist Arup, CBE, MICE, MIStructE (16 April 1895 – 5 February 1988) an Anglo Danish engineer, was born in Newcastle upon Tyne. Generally considered the foremost engineer of his era, he created the firm Arup and Partners in 1946 as a team of structural consultants. The complex level of design considerations that the partnership encountered led to the creation of Arup Associates in 1963.

Peter Buckthorpe born 1942, commenced his career in 1958 as a trainee engineer with W V Zinn & Associates. On completion of this major project, in 1966, Peter joined Ove Arup and Partners, where he began his relationship with Ted Happold and some of his future Buro Happold partners. At Arup, Peter worked as Design Engineer on Hyde Park Cavalry Barracks before departing for West Africa where he spent several years in charge of structural and civil engineering projects.

Professor Sir Edmund Happold (1930–1996), better known as Ted Happold, was a Professor of Biochemistry at the Leeds University, a Structural Engineer and founder of Buro Happold. After a grammar school education, he studied geology at the University of Leeds. He was directed to work as an agricultural labourer and then truck driver and dragline operator. This aroused his interest in construction, so he returned to Leeds University, where he achieved a BSc in Civil Engineering in 1957.
