Mason Clark Associates provided structural design and project management services for a coordinated space at Sheffield Hallam University. This is to house their Science, Technology, Engineering and Mathematics (STEM) subjects. The original configuration comprised of two existing buildings with an open air concourse between them, itself over a double height basement to one of the buildings. The main challenge of the project was to join these with a new roof to create an internal atrium as a focal point of the new department.
The buildings were of very different construction; a concrete framed building originally built as the University’s library in 1972, and a steel building dating from 1992. The concrete framed building contained the challenge of removing the reinforced shear walls and stairs at the third floor to open out the space for teaching. The new atrium roof is a braced steel frame, utilising fabricated trusses to span the distance between the two buildings. These are set at angles to run parallel with the full width roof lights. Further works include moving the lift shaft from one side of the atrium to the other, and replacing the large staircase at the end. A new steel framed elevated walkway between the two buildings has also been provided, together with general refurbishment works.
