Preservation by record (archaeological excavation)
152 As per NPS EN-1 5.8.20 and NPPF 141, where the loss of the whole or a material part of a heritage asset’s significance is justified, EAOWare required to record and advance understanding of the significance of the heritage asset before it is lost.
153 Where archaeological remains of particular complexity and/or significance are identified through trial trench assessment, advance/‘set-piece’ archaeological excavations may be required, to take place as far in advance of the construction programme as possible.
154
The following methodology should also be followed for archaeological deposits identified through assessment by Archaeological ‘Strip, Map and Record’, or watching brief.
155 A Method Statement for Archaeological Excavation would be produced. Specific research aims and sampling strategies would be appended to the method statement, determined on a site by site basis. If repetitive archaeological features are encountered, feature specific research aims and sampling strategies may also be appended to themethod statement.
156
The regional research aims would be addressed in determining the need for further specialist analysis. The potential for adding pubic benefit to the project through the popular publication of the survey results would also be considered as part of the programme of post excavation work.
1.11.2 157 Aims and objectives
Preservation by record (archaeological excavation) aims to remove overburden under the direction of a suitably qualified archaeologist, in areas scheduled in the construction programme, down to the intended archaeological horizon.
158 1.11.3
The aim of archaeological excavation is to preserve by record archaeological remains thatmay be altered, damaged or destroyed by construction works.
Methodology
159 Preservation by record (archaeological excavation) would be subject to a Method Statement for Archaeological Excavation. However, a generalised methodology is outlined below, as per relevant SCC archaeological guidance.
160
Archaeological excavation initially requires the removal of overburden in areas of impact scheduled in the construction programme, down to the first archaeological horizon, or the natural substrata, whichever is encountered first. The topsoil and depth
