Description
English Heritage wishes to establish framework agreements for the 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 plotting. 1.1 Plotted vector output by use of photogrammetric plotting techniques; base data to be generated in 3D. 1.2 Orthophotographic output including provision of digital elevation model (DEM) data and overlaid or corrected digital images. Rectified photography: rectified photography and control package of building fabric, elevations, ceilings and floors with precise coordinate control, by use of marked control targets and detail points. 1.3 Generation of digital rectified photomontages. Lot 2: Low Level Aerial Photography: Split in to: 2a; From manually controlled platform 2b; Using Programmable flight control systems: minimum height 2 metres to maximum height 120 metres Lot 3. Topographic Survey of historic landscapes and sites at 1:500, 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 as described above as applied to historic buildings and landscapes, with specific understanding of the group or groups of services for which they wish to be considered. The contract period will be 3 years, commencing April 2015, 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 Historic Scotland.
It is envisaged that the top scoring 5 to 7 suppliers from the selection process, for each lot each lot will be invited to tender.
We anticipate that 3-5 suppliers for each lot will then be appointed as framework suppliers.
Selection:
Suppliers should complete the electronic questionnaire and submit by the date specified, along with electronic examples of previous work
Examples of work can be used over more than 1 lot, providing that their relevance is demonstrated within the description and through any samples provided.
Samples should be provided in PDF format, at their intended plots scale when printed at 100 %.
Samples for Lots 2a and 2b may be provided in JPEG format.
Additional Information:
English Heritage:
Please note that from 1.4.2015 The Historic Buildings and Monuments Commission (trading as English Heritage) will be split into two separate organisations. A new charity will be set up to manage the National Heritage Collection. The charity will retain the name English Heritage, but will be an entirely new organisation. The remainder of English Heritage (which provides planning and conservation services and advice) will operate under the new name of Historic England, but will remain as the same legal entity.
Historic Scotland:
The functions of Historic Scotland and the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) will fully integrate by October 2015 to form a new organisation, Historic Environment Scotland (HES). There is a Bill currently making its way through the Scottish Parliament to establish this new body. Contracts and Agreements will be assigned to HES from Historic Scotland and RCAHMS at that time.
