## Summary

Caerlaverock Estate is procuring environmental and habitat restoration works at Caerlaverock Estate near Dumfries. The project involves creating 24 ponds across the estate, covering approximately 22,000 square metres. Seven ponds will be designed specifically for natterjack toads, restoring historic breeding locations and habitat. The remaining 17 will provide general habitat and water restoration. The ponds are intended to support wider wetland ecosystems, including migratory wildfowl, damselflies and aquatic insects. They will also provide natural flood and surface-water management, diffuse pollution control and sediment catchment from adjacent hillside fields. The requirement is classified as construction work for environmental protection and nature conservation. The work is organised as one requirement covering the pond network and associated restoration activities.

The buyer invited offers through a tender using an open procedure, with electronic submission. The deadline for responses was 24 September 2026 at 17:00 UTC. Bid opening was scheduled for 25 September 2026 at 09:00 UTC, with the award period beginning at that time. The contract is scheduled to run from 13 October 2026 to 31 March 2027. Its estimated value is £55,000 including the single lot. Bids must remain valid until 23 October 2026. Submissions must be in English, and variants are not allowed. Electronic payment and ordering will be used, while electronic invoicing is permitted. The tender requires bidders to provide the names and qualifications of staff assigned to the work.

This opportunity suits contractors experienced in ecological construction, wetland creation, pond excavation and habitat restoration. Relevant capability includes designing or delivering ponds for protected or priority species, restoring breeding habitat, and constructing connected habitat networks rather than isolated features. Suppliers should be able to carry out earthworks and water-management works while controlling sediment and diffuse pollution from surrounding land. Experience of natural flood management, wetland ecology and wildlife-focused landscape works would be particularly relevant. The requirement also calls for named project staff and their professional qualifications, so bidders need an appropriately qualified delivery team and the capacity to complete multiple pond projects across an estate. Contractors combining civil engineering, drainage, environmental management and nature-conservation expertise are well placed to compete.

## Notice

We plan to create a mixture of Natterjack Toad ponds (designed to reintroduce historic breeding locations/habitat specifically for this species) (NJT Ponds) and more general habitat and water restoration ponds (HWR Ponds). The HWR ponds are designed to reinstate general habitat, but also to provide natural flood and surface water management, together with diffused pollution control and sediment catchment from adjacent hillside fields - acting as a buffer zone. In winter, the ponds will reach their maximum surface area, providing large waterways for migratory wildfowl. In spring the NJT ponds will reduce in size and leave a small deepening which will heat up quicker to trigger the Natterjack spawn. In summer they will provide habitat for damselflies and aquatic pond insects. We plan to create 24 ponds, totalling approximately 22,000m2 across the estate adding to existing habitat and creating new wetland habitats. 7 will be natterjack toad specific ponds, and 17 general habitat ponds. Rather than thinking of these ponds as individual assets, we have grouped them into pond networks by holding but also layering other wildlife restoration efforts nearby to maximise the ecological benefit for the habitat. The layout of each having been specifically designed to support whole ecosystems.
