The Observational Method in ground engineering: principles and applications (R185)

The Observational Method in ground engineering is a continuous, managed, integrated process of design, construction control, monitoring and review which enables previously defined modifications to be incorporated during or after construction as appropriate. All these aspects have to be demonstrably robust. The objective is to achieve greater overall economy without compromising safety. The Method’s origins are found in the development of “modern” soil mechanics theories in the late 1940s, when an integrated process for predicting, monitoring, reviewing and modifying designs evolved. In the 1990s there has been a noticeable increase in its use, and extension of its principles. The OM has been recognised as a design method in design codes such as Eurocode 7 (BSI, 1995).This publication aims to provide technical and contractual guidance that will lead to more effective and innovative application of the Observational Method. Topics covered in the book include history and definition of the Method; concepts, principles and practice; contractual framework; and tunnel, excavation and other applications. For design, specification, and construction managers, and for clients and civil engineers involved in civil and geotechnical works, this is a bookshelf must.

Key words: ground engineering, ground investigation and characterisation.
