Earthworks Manual – General considerations

The Earthworks Manual is a collection of state of the art and good practice to inform readers about earthworks management.

Part 1 is a summary of the different phases and associated topics to be considered in the Earthworks process for the construction of earth-structures.
The definitions presented are an essential preliminary to provide a common basis for all member countries.
The concepts dealt with here, are representative of the whole Earthworks activity, from design of the road infrastructure, until its construction and related controls. Specific features highlight the importance of the strategy implemented in order to consider the economic and environmental dimensions of the project.
The quality of the stable and durable support platforms (for road or rail) meets performance specifications. It should be emphasised that the required quality is a fundamental issue in the design of earthworks for construction and maintenance. The predominant objective today is the resilience of infrastructures and new requirements due to climate change.

This document, already published in 2019, is included here in the new set of the Earthworks Manual.
