## Summary

Shetland Islands Council commissioned a groundwater site investigation at Colvister Quarry on Yell, Shetland. The work is a specialist environmental and engineering consultancy service, focused on investigating groundwater conditions at the quarry site (CPV 71351500). The Council is the buying organisation and the service location is Yell. The requirement was arranged as a call-off from the SXL 1025 Engineering and Technical Consultancy arrangement. It was a single requirement covering groundwater site investigation rather than a wider construction package or supply of equipment. The selected provider was Ramboll UK Ltd, an Edinburgh-based engineering and technical consultancy. This opportunity is therefore most relevant to firms with practical experience of groundwater investigation and the ability to deliver specialist technical consultancy in Shetland.

The procurement has been awarded and the tender is complete. The single groundwater site investigation lot was awarded to Ramboll UK Ltd. The contract is active and was signed on 28 July 2026, with a value of £57,858 GBP. The Council used a limited award procedure without prior publication of a call for competition, by calling off from the SXL 1025 Engineering and Technical Consultancy arrangement. The procurement was treated as outside the scope of the relevant directive and covered by the Government Procurement Agreement. One bid was recorded for the lot; it was submitted electronically. The published outcome identifies Ramboll UK Ltd as the selected supplier. The data records no separate contract duration or award date, so the signed date is the key recorded contract milestone.

This award shows a defined requirement from Shetland Islands Council for specialist groundwater investigation connected with a quarry site on Yell. It provides a useful benchmark for engineering and environmental consultancies that want to understand the Council’s demand for technical site investigation and the scale of a single call-off requirement. A credible future competitor would need demonstrable groundwater investigation capability, relevant engineering or technical consultancy experience, and the ability to work at a remote Shetland location. Familiarity with public-sector call-off arrangements, particularly the SXL 1025 Engineering and Technical Consultancy route, would also be commercially relevant. The successful supplier was a large consultancy, while the recorded bid statistics show no SME bid, indicating a potential opportunity for an SME with the necessary specialist expertise and delivery capacity to strengthen its position.
