Chur Glas Tenders Filed – The Tunneling Journal

Six shortlisted bidders from around the world are participating in the Tender Process (ITT) to carry out the civil, mechanical and engineering works for the Coire Glas Hydro project in Scotland. Coire Glas is said to be the first large-scale hydro-pumped storage system to be built in the UK for over 30 years and the ITT for major construction work has attracted global interest.

Bid reviews are ongoing, following which it is expected that one preferred bidder will be selected for the mechanical and electrical component and two bidders will be selected for the civil engineering component. Successful bidders will work with the Chur Glas team on a program of extensive ground survey work, running from July 2022 to autumn 2023, which will allow them to refine their proposed project designs. The selection of the preferred civilian bidder, who will work with the successful mechanical and electrical bidder to construct Coire Glas on a turnkey basis, is scheduled for fall 2023.

The construction phase of the project is expected to begin in spring 2024 and is expected to support up to 500 jobs.

The six shortlisted bidders for the main construction works were:

For the civil engineering scope:

  • Consortium Bechtel Ltd., Acciona Construcción SA and Webuild SpA
  • Consortium BAM Nuttall Ltd, Eiffage Génie Civil SA and Marti Tunnel AG
  • Consortium Dragados SA and BeMo Tunneling UK Ltd

For the mechanical and electrical plant scope:

  • Partnership ANDRITZ HYDRO GmbH and Voith Hydro GmbH & Co KG
  • GE Hydro France.

“The timely receipt of bids from the six shortlisted bidders is another milestone for the Coire Glas project and we are grateful to the bidders for their continued interest in the project. We are encouraged by the contents of the tenders which now offer the Coire Glas project team several options on how the construction of the project could be undertaken. It will take some time to carefully consider and review the bids and we look forward to working with the bidders as we work to make our selection decision,” said Ian Innes, Project Manager for Coire Glas.
