Wallace Stone

What Wallace Stone does

Wallace Stone is a privately held Scottish civil engineering consultancy founded in 1973, specialising in marine and floating structures including harbours, piers, jetties, ferry terminals, pontoons, breakwaters, slipways, and coastal protection works, alongside road and footbridges and small-scale hydro electric projects. Operated as Wallace Stone LLP from three offices — Glasgow (headquarters), Dingwall, and Stornoway (Isle of Lewis) — the firm provides end-to-end professional services from feasibility studies and concept design through detailed design, project management, site supervision, and contract management. The practice supplements its core engineering design with in-house specialist capabilities including diving inspection of marine structures, bathymetric surveying, underwater setting out, and procurement of statutory consents for marine works.

The firm's client base is dominated by the Scottish public sector, including Stornoway Port Authority, Caledonian Maritime Assets Ltd (CMAL), Transport Scotland, Comhairle nan Eilean Siar, Ullapool Harbour Trust, and other harbour trusts and local authorities, with private sector work spanning renewable energy (wind farm support infrastructure), aquaculture, quarrying, and community development trusts. Revenue is generated on a project-based professional services model secured via competitive tendering, framework agreements, and direct commission, with fees calculated by scope, complexity, and client requirements and no publicly disclosed pricing. Notable commissions include the £65M Stornoway Deep Water Port (2023), the £38M Uig Ferry Terminal Upgrade, the £18.5M Scrabster Ola Pier Redevelopment, and the £17.1M Tarbert Ferry Terminal Phase 1, which collectively demonstrate the firm's involvement on the largest Scottish island marine infrastructure programmes.

The business is independently owned and managed by its partners, with no disclosed external investment, private equity ownership, or acquisition activity. Wallace Stone holds ISO 9001 (since 2015) and ISO 14001 (since 2024) accreditations and is a member of the Association for Consultancy and Engineering, with consistent industry recognition through Scottish Civil Engineering Awards, Saltire Society commendations, and RICS awards. Headcount is 11-50 employees, all based in Scotland, and the firm operates exclusively within the Scottish market without disclosed international expansion.
