This Technical Guidance Note is intended to act as an aide to those seeking to design an unreinforced masonry retaining wall. Following this guidance will prevent cracking and ensure that the wall performs as originally intended.

The note will not cover the design of reinforced masonry retaining walls and variants of that form. Such reinforcement typically strengthens the wall itself against induced bending stresses and the wall’s geometry will therefore be somewhat different to that of an unreinforced retaining wall.

The note will also not discuss the applied actions that a retaining wall will be subjected to, nor the construction of retaining walls. These subjects have previously been covered in the following Technical Guidance Notes: Level 1, No. 8: Derivation of loading to retaining structures and Level 1, No. 33: Retaining wall construction. It is assumed that the reader is familiar with the content of both these notes.

Technical Guidance Note (Level 2, No. 16): Design of reinforced concrete bored piles

Piled foundations are one of the first aspects of scheme design a structural engineer needs to consider during a project's development. It is at this crucial stage that, without any specialist input, the structural engineer must make recommendations based on the typically limited knowledge they have on the subject.

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.

Technical Guidance Note (Level 2, No. 7): Designing a concrete pad foundation

Technical Guidance Note (Level 2, No. 7): Designing a concrete pad foundation

The purpose of a pad foundation is to spread a concentrated force into soil. They are one of the most simple and cost effective types of footings for structures. Provided the founding soil is of sufficient strength and is not too deep to reach, pad foundations are the preferred solution for foundations due to the straight forward nature of their design and construction.

This Technical Guidance Note covers the design of concrete pad foundations, both mass and reinforced concrete forms. It will not, however, discuss how the bearing capacity of the soil is determined, as that is explained in Technical Guidance Note 19 (Level 1) Soil bearing capacity. It is suggested that you read that text in conjunction with this, in order to gain a more comprehensive understanding of the topic.

Technical Guidance Note (Level 2, No. 9): Designing a reinforced concrete retaining wall

Technical Guidance Note (Level 2, No. 9): Designing a reinforced concrete retaining wall

Although retaining walls have been the subject of two earlier Technical Guidance Notes; No. 8 (Level 1): Derivation of loading to retaining structures and No. 33 (Level 1): Retaining wall construction, their design has not been covered. This guidance note focuses specifically on the design of reinforced concrete gravity retaining walls.

There are three different forms of this type of wall, all of which are designed to resist overturning and sliding failure. The primary difference between them is their height. The taller the retaining wall, the more likely that counterforts and beams spanning between them will be necessary. This note describes how all of these forms of retaining wall can be designed.
