Whitesands Flood Protection Project: design and staging insights for engineers

30 Second Briefing
Work has started on the Whitesands Flood Protection Project in Dumfries, with Dumfries and Galloway Council working alongside contractor McLaughlin & Harvey, project manager Turner & Townsend, and design consultant Jacobs. The scheme will deliver engineered flood defences along the River Nith at Whitesands, a town-centre area repeatedly affected by fluvial flooding. Early phases are expected to focus on site clearance, temporary works and establishing construction access, with detailed design and phasing critical to maintaining traffic flow and protecting adjacent riverfront assets.
Technical Brief
- Initial works include vegetation clearance and removal of existing street furniture along the river frontage.
- Temporary traffic management layouts are being installed to segregate plant movements from public access routes.
- Site compound establishment incorporates controlled wash-down areas to prevent sediment-laden runoff entering the river.
- Early ground investigations are being revisited to refine foundation levels and seepage control measures for permanent defences.
- Coordination with utility providers is required to protect and divert buried services intersecting proposed flood wall alignments.
- Construction phasing is being sequenced to maintain emergency vehicle access to the town-centre river corridor.
- Safety planning is constrained by river levels, requiring adaptive safe-working envelopes near the waterline.
- Lessons on integrating fluvial defences into constrained historic town centres will inform future flood schemes.
Our Take
Dumfries and Galloway Council’s earlier approval of a £68.6M River Nith defence scheme in our database signals that the Whitesands Flood Protection Project is part of a larger, town-scale reconfiguration of flood risk rather than a standalone embankment job.
McLaughlin & Harvey’s presence here follows a run of Scottish public-sector and marine infrastructure work in our coverage (University of Edinburgh, Port of Nigg, Passivhaus schools), suggesting the contractor is consolidating a strong regional position for complex, multi-stakeholder schemes.
Jacobs and Turner & Townsend appearing together on this safety-tagged infrastructure project mirrors their roles on other major UK industrial builds in our database, indicating the council is importing Tier 1-style programme and risk management practices into a local authority flood scheme.
