(b) A detailed archaeological survey and analysis of the demesne wall associated with Drumcondra Castle (CH01) and of the ruined outbuilding associated with Richmond House (CH02) including full photographic, written and drawn record of both structures. (c) (i) No construction or site preparation work may be carried out on the site until all archaeological requirements of the planning authority are complied with. (ii) The project shall have an archaeological assessment (and impact assessment) of the proposed development, including all temporary and enabling works, geotechnical investigations, for example boreholes, and engineering test pits, carried out for this site as soon as possible and before any site clearance/construction work commences. The assessment shall be prepared by a suitably qualified archaeologist and shall address the following issues. (a) The archaeological and historical background of the site, to include industrial heritage. (b) A paper record (written, drawn, and photographic, as appropriate) of any historic buildings and boundary treatments, etc. (c) The nature, extent and location of archaeological material on site by way of archaeological testing and/or monitoring of the removal of overburden. (iii) The impact of the proposed development on such archaeological material. (iv) The archaeologist shall forward their Method Statement in advance of commencement to the planning authority. (v) Where archaeological material is shown to be present, a detailed Impact Statement shall be prepared by the archaeologist which will include specific information on the location, form, size and level (corrected to Ordnance Datum) of all foundation structures, ground beams, floor slabs, trenches for services, drains etc. The assessment shall be prepared on the basis of a comprehensive desktop study and, where appropriate/feasible, trial trenches excavated on the site by the archaeologist and/or remote sensing. The trial trenches shall be excavated to the top of the archaeological deposits only. The report containing the assessment shall include adequate ground-plan and cross-sectional drawings of the site, and of the proposed development, with the location and levels (corrected to Ordnance Datum) of all trial trenches and/or bore holes clearly indicated. A comprehensive mitigation strategy shall be prepared by the consultant archaeologist and included in the archaeological assessment report. (vi) No subsurface work shall be undertaken in the absence of the archaeologist without his/her express consent. The archaeologist retained by the project to carry out the assessment shall consult with the planning authority in advance regarding the procedure to be adopted in the assessment. (vii) One hard copy and one digital copy in pdf format containing the results of the archaeological assessment shall be forwarded on completion to the planning authority. The planning authority (in consultation with the City Archaeologist and the National Monuments Service, Department of Housing, Local Government and Heritage) shall determine the further archaeological resolution of the site. (viii) The developer shall comply in full with any further archaeological requirement, including archaeological monitoring, and if necessary archaeological excavation and/or the preservation in situ of archaeological remains, which may negate the facilitation of all, or part, of any basement. (ix) The developer shall make provision for archaeological excavation in the project budget and timetable. (x) Should archaeological excavation occur the following shall be submitted to the planning authority: (a) A bi-weekly report on the archaeological excavation during the excavation and post excavation period. (b) A preliminary report on the archaeological excavation not later than four weeks after the completion of the excavation. (c) A final report on the archaeological excavations not later than 12 months after the completion of the excavation. (xi) Before any site works commence, the developer shall agree the foundation layout with the planning authority. (xii) The developer shall provide arrangements, acceptable to the planning authority, for the recording and for the removal of any archaeological material which the authority considers appropriate to remove. In default of agreement on any of these requirements, the matter shall be referred to An Bord Pleanála for determination.
