The radiocarbon samples.
Details of the 2012-16 research programme are still being finalised, but it is likely that between 2000 – 2500 AMS measurements will be needed over the next four years (1.8.2012 – 31.7.2016). The vast majority of results will be integrated into Bayesian chronological models.
Collaborating laboratories will need to process a full range of samples, including bone collagen, charred organic residues on potsherds, charcoal and other charred plant material, cremated bone, and bulk sediments. Arrangements for the measurement of C:N ratios, ?13C, and ?15N will also be needed. It is possible that dating of a small number of samples of other materials (eg leather, chitin, and shell) may be required, and that some samples may have been conserved.
?13C measurements are required for all radiocarbon measurements. Quoted errors must be estimates of total error. It is anticipated that almost all samples will date to after 10,000 BP, the majority being of less than one half-life.
The contract will be split into 3 lots to allow inter laboratory comparison. Only one contractor will be awarded a lot. Each Lot will be made up of approximately 700 to 900 AMS measurements but this figure may vary.
All samples will be selected, documented (using EH dating forms), and identified by members of the project teams and the EH Scientific Dating Team. From receipt by the collaborating laboratory, results are requested within 12–16 weeks (requested turnaround will be specified on submission).
Research input will be needed from collaborating laboratories over such issues as appropriate replication, selection of organic fractions, particularly low-collagen sites etc. All collaborators will need to provide full, written, methods statements which will be amended for use in publication texts as appropriate. Some input will be needed in publishing problematic or unexpected results, and in meeting particularly challenging dating problems. A representative of each collaborating laboratory will be a named author on publications arising from the research programme and on appropriate volumes in the English Heritage Radiocarbon Dates series. Collaborators will need to read and comment on draft publication texts as appropriate.
The contract will be split into three lots to allow inter-laboratory comparison, and will consist of approximately 700 – 900 AMS measurements over four years (this figure may vary). Only one contractor will be awarded each lot. Applications for the entire research programme will not be considered. All bids will be assessed using the criteria stated in the tender documentation, and the top three scoring tenderers will be awarded a lot each.
