Archaeological watching brief


An archaeological watching brief is defined as the monitoring, by an appropriately qualified archaeologist, of third party activities which may impact upon or expose archaeological remains during on-site construction activities. Accordingly, a watching brief is not intended to reduce the requirement for excavation or preservation of known or inferred deposits, and it is intended to guide, not replace, any requirement for contingent excavation or preservation of possible deposits.


180 Where pre-construction assessments have indicated no specific archaeological potential, and where Archaeological ‘Strip, Map and Record’ has not been previously implemented, a watching brief would be maintained during construction.


1.12.2 181 Aims and objectives


The aim of the archaeological watching brief is to identify, then preserve, either by record or in situ, archaeological remains that may be altered, damaged or destroyed by the onshore electrical transmission works. The objectives of the survey are to provide data on the date, character, quality, survival and extent of archaeological deposits within the working area of the Onshore Cable Route (see preservation by record (archaeological excavation) Part 1.11).


182


This information would clarify whether any remains are of national or international importance and thus warrant consideration for preservation in situ; or alternatively form the basis of mitigation measures that may seek to limit damage to significant remains (see preservation in situ Part 1.6).


1.12.3 183 Conditions


Activities that may be monitored include, but are not limited to: •


•


• • •


Topsoil stripping of 35m working width, CCS, HDD areas, off easement accesses and temporary laydown and construction compound areas;


Any significant drainage excavations, particularly within archaeologically sensitive areas; Benching;


Cable trench excavation;


Excavation of launch and reception pits for non-open cut crossings or HDD sections;
