Historic England wishes to establish framework agreements for a range of metric survey services carried out on historic sites and monuments. The services under the framework agreements fall into the following categories: Lot 1. Image Based Survey including photogrammetric cover of building fabric, elevations, ceilings and floors. Precise co-ordinate control by use of marked control targets and detail points. Photo cover and control commensurate with up to 1:20 scale photogrammetric output. 1.1 Orthophotographic output including provision of digital elevation model (DEM) data. Lot 2: Low Level Aerial Photography: For inspection and mapping. Minimum height 2 metres to maximum height 120 metres Lot 3. Topographic Survey of historic landscapes and sites at 1:200 and 1:100 scales using terrestrial techniques. Lot 4. Measured Building Survey in the form of plans, sections, elevations and sectional elevations at 1:50 and 1:20 scales. Consultants are required to be conversant with all aspects of metric survey described above as applied to historic buildings and landscapes, with specific understanding of the Lot(s) for which they wish to be considered. The contract period will be 3 years, commencing April 2022, with the option to extend for a further year by mutual agreement with the suppliers. The total overall expenditure on these services is estimated to be in the region of 100 000 GPB per annum (please note that this figure is given for guidance only and cannot be guaranteed). Services under the frameworks will also be ordered by English Heritage and Historic Environment Scotland. It is envisaged that the top scoring 6 to 8 suppliers from the selection process, for each lot will be invited to tender. We anticipate that 4-6 suppliers for each lot will then be appointed as framework suppliers.
