This Technical Guidance Note describes the method by which bored piles are designed using the current UK codes of practice, i.e. BS EN 1997 (Eurocode 7). It explains how to interpret soil conditions and design piles to match what has been discovered following a site investigation.
The note does not address the types of piling systems that are available, nor the technical issues concerning their installation; these questions are covered in Technical Guidance Note Level 1, No. 23 Introduction to piling.
The note explains how to design what is essentially a buried column of concrete to resist forces from the superstructure that are applied to it. It concerns the design of a single pile and not one that is part of a group. For information on how grouped piles differ in their design approach, the reader is directed to Cl. 6.3.3 of BS 8004:2015.

This note describes how steel fibre reinforced concrete groundbearing slabs are designed.
This note explains how reinforced concrete walls are designed to withstand high in-plane bending forces, in accordance with Eurocode 2.
Portal frames are a simple and very common type of framed (or skeleton) structure. Steel portal frames, in particular, are a cost-effective structural system to support building envelopes requiring large column-free spaces.
