The Construction Directorate of the DETR supports the programme of innovation and research to improve the construction industry’s performance and to promote more sustainable construction. Its main aims are to improve quality and value for money from construction, for both commercial and domestic customers, and to improve construction methods and procedures.
This book proposes the distributed prop load method for establishing temporary prop loads for design. Developed from the Peck approach, it is based on a comprehensive survey of field measurements of prop loads. Distributed prop load diagrams, derived from analyses of the measured loads, are provided, from which prop loads may be obtained. The book explains the application of this method for single and multi-propped excavations of varied geometry, flexible and stiff walls, and the range of UK ground conditions, illustrated by worked examples. Guidance covers temperature effects, buildability, use of the Observational Method, instrumentation, and choice of temporary propping systems. Also included are contractual arrangements, performance requirements, allocation of responsibility and the legal context. At the end of each chapter there is a helpful checklist of key points. Temporary propping of deep excavations is a valuable addition to the libraries of temporary works designers, geotechnical engineers, project managers and clients.

Temporary propping of deep excavations – guidance on design
The use of different calculation methods for prop loads is leading to significant variation in results. There is a need, therefore, for an authoritative statement on the practical limits to which ground movements can be restricted.
Temporary propping of deep excavations - guidance on design

Distributed prop load diagrams, derived from analyses of the measured loads, are provided, from which prop loads may be obtained. The book explains the application of this method for single and multi-propped excavations of varied geometry, flexible and stiff walls, and the range of UK ground conditions, illustrated by worked examples. Guidance covers temperature effects, buildability, use of the Observational Method, instrumentation, and choice of temporary propping systems. Also included are contractual arrangements, performance requirements, allocation of responsibility and the legal context. At the end of each chapter there is a helpful checklist of key points. Temporary propping of deep excavations is a valuable addition to the libraries of temporary works designers, geotechnical engineers, project managers and clients.

Temporary propping of deep excavations – guidance on design
The use of different calculation methods for prop loads is leading to significant variation in results. There is a need, therefore, for an authoritative statement on the practical limits to which ground movements can be restricted.
