DNAire Fishpass Package

DNAire is a project led by the Environment Agency and Aire Rivers Trust which aims to re-establish a sustainable Atlantic salmon population, as well as eel, lamprey and sea trout, in the River Aire.

This will be achieved by reconnecting the River Aire from Leeds City Centre to Gargrave in the Yorkshire Dales by building four fish passes.

What we are seeking to achieve.

The re-establishment of a sustainable salmon population will be achieved by building a fish and eel pass on each of the four weirs at Armley Mills, Kirkstall Abbey, Newlay and Saltaire.

These are the final four major obstacles to the return of Atlantic salmon, eels and sea trout to the River Aire.

Each fish pass will be a multi-species Larinier type pass enabling migratory fish species to move upstream and for resident coarse fish to move along the river to feed, breed and find shelter.

What we require.

We would like to gauge market interest in a Design and Build contract to deliver the design and construction of these four fish passes.

Initially, we require detailed (construction) designs of the fish and eel passes as well as detailed construction costs and timetables.

The deadline for delivery for full designs, timetable and costs is 30 November 2018.

Any company that secures the contract for the Stage 1 construction designs and costings will also secure the contract to build the fish passes as part of Stage 2.

Suppliers should be aware that the construction stage will not start before August/September 2019 and therefore should take this into account when responding to this notice and submitting any future bids for this requirement.

Questions for consideration Is your organisation able to provide full construction designs, timetables and full costings and commit to this offer for a 12 month period between the Employer receiving full designs and commencement of any works by the winning bidder?

Please detail any perceived issues relating to the inclusion of a 12 month period between the provision of full designs and the commencement of any works...
