As well as the more traditional range of archaeological fieldwork, WA was carrying out an increasing range of surveys and assessments. These might look at the history and development of discrete areas or broader landscapes, coastal margins or the seabed, individual buildings or collections of buildings, earthworks, environmental or artefactual data, or any combination of these categories. While many of the surveys were preliminary to fieldwork, others were an end product in their own right. 
WA had carried out a number of projects for the Defence Estates since 1998 under Specialist Term Commissions. The work of the previous years had included excavations at Tidworth and RNAS Yeovilton and a monument survey of the Salisbury Plain Training Area. During 2001, surveys and assessments of the archaeology of the Aldershot and Longmoor, and Cinque Ports Training Areas were carried out in south-eastern England, while building recording and earthwork surveys were undertaken at Okehampton Camp in Devon. 
While the surveys addressed different aspects of the various sites, they were all carried out with a view to management and preservation. Much of the work was made easier by the use of a Global Positioning System (GPS) which helped locate sites in featureless or overgrown terrain. 
WA's Coastal and Marine section conducted a preliminary survey of the archaeological and historical heritage of part of the north Kent coast. The survey was used to assess and develop practical and technical methods of conducting similar surveys in the future.
