What is being bought

This project will undertake flow derivation reviews at 13 selected Environment Agency gauging stations to assess the accuracy, reliability and suitability of existing flow derivation methods. The reviews will examine current methodologies, identify limitations and uncertainties affecting the quality of derived flow records. Where justified by the available evidence, improved flow derivation methods and ratings will be developed, including the derivation of a modelled high-flow rating for one specified station if sufficient.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 71. The category anchor is Flow-monitoring services (71631440); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence
Market: CPV division 714,5694 median · 28.6 average (1,408 of 4,569 with a bid count)3.8 average (1,548 of 4,569 with named award suppliers)Not published
Same buyer12Not publishedNot publishedNot published
Delivery region: UK1,0413 median · 61.6 average (315 of 1,041 with a bid count)6.2 average (363 of 1,041 with named award suppliers)Not published
Similar published value (0.5×–2×)2664 median · 4 average (1 of 266 with a bid count)1 average (1 of 266 with named award suppliers)Not published

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
