Work on this building ! rst began in 1978, a" er Richard Rogers and Part-ners were the eventual winners of a competition set out by the executive committee of Lloyd’s. Peter Rice was one of the members of the winning team and was appointed the primary structural engineer on the pro-ject. In his book ‘‘Peter Rice - An Engineer Imagines’’, Rice re# ects on the parts of the building to which he had the most involvement with.He began by considering the clients needs and required functionality of the building ie. a open o$ ce environment that had possiblities of futher ex-pansion and growth if ever necessary. Due to the larger than average spans that would no doubt be created if the clients brief was to be met, Peter designed a structural system that not only allowed the structural re-quirements to be met, but also created the desired aesthetics from Rogers.
% e plan of the building is a rectangler doughnut, 68.4m by 46.8m overall, with 18.2m span dloor plates. In the middle is a spectalar full-height atrium, 12 stories high with escalators criss-crossing the void. % e main structural elements consist of 28 in-situ concrete columns, just over a meter in diame-ter, set on a grid of 10.8m centres ( 20 along the facades and 8 in the atrium). % ese support the # oor plates on a 18.2m x 10.8m grid with 5.4m cantile-vered corners. % e # oor plates are formed from a 1.8m square grid of in-situ concrete beams, the ! rst layer of the # oor system. % e beams have short con-crete stubs at the grid intersections that in tum support a thin concrete # at slab. % e zone between the beams and slab are used for building services. For speed and ease of construction, the slabs were cast using a permanent form-work of steel plates, from which the building services were later suspended.
