    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.
