The design method used for the pile caps relies heavily on the BS8110 97 code. In some cases the BS8110 97 code does not provide adequate guidance on the design of pile caps so in those cases the following sources were used to supplement the design:

• Ray, S.S. Reinforced Concrete Analysis and Design. Chapter 7, "Design of Piled Foundations". Blackwell. 1995
• Allen, A.H. Reinforced Concrete Design to BS 8110 Simply Explained. Spon Press Publication.
