the results of a programme of trial trenching. The Method Statement, supported by figures, would be provided to EH and SCC for approval in advance of the work.
1.10.4 142 Methodology
All stripping of overburden within an area designated for Archaeological ‘Strip, Map and Record’ should be carried out by 360° excavator equipped with a toothless ditching bucket, and under constant archaeological supervision.
143
The topsoil strip continues to the depth of potential archaeological survival; i.e. all topsoil and subsoil is removed to the first archaeological horizon or natural horizon, whichever is encountered first.
144
Topsoil is removed and stored in a way that allows for clear identification of archaeological horizons or features. This is determined on site by the monitoring archaeologist.
145
Archaeological features are considered likely in plots defined for Archaeological ‘Strip, Map and Record’. It should be stressed that it is preferable that archaeological features are preserved in situ by means of a local variation in the works. These decisions will be made by agreement between EH, SCC and EAOW, taking into account other environmental constraints and mitigation requirements. Otherwise, preservation by record (archaeological excavation) procedures will be implemented (see Part 1.11).
146 Where archaeological remains are identified and preservation by record (archaeological excavation) is determined the preferred mitigation approach, they will be fenced off and equipped with adequate signage. These areas will be considered ‘locked-out’ to construction. Plant or vehicle access will not be permitted within ‘locked- out areas’ until declared complete by EAOW with input from the Project Archaeologist.
147
Haul road construction and cable trenching will not be implemented within ‘locked-out’ areas until the archaeological remains are fully investigated and recorded to professionally accepted standards.
148
Contractor vehicles may move safely in between fenced-off areas, once declared archaeologically sterile.
149 Where abundant, features will be archaeologically excavated and recorded and areas monitored and signed off by SCC and EH in the order that the cable construction method requires:- firstly the haul road will be investigated and recorded in order to allow vehicular access along the working width, and secondly, the cable centre-line will be cleared to allow excavation of the cable trench.
