What CLM CONSTRUCTION does

Currall Lewis and Martin (Construction) Ltd, trading as CLM Construction, is a UK-based civil engineering contractor headquartered in Oldbury, West Midlands. Founded in 1867 and operating under employee ownership since a 2001 management buyout, the firm delivers eight core service lines: waterways (canals, rivers, reservoir repairs), cycleways and multi-user greenways, drainage, retaining walls, sheet piling, highway works, bridge construction and maintenance, and concrete repair with cathodic protection. CLM has built specialist depth over more than 40 years in structural concrete repair using flowable materials, developed in partnership with Fosroc, and is a full member of the Concrete Repair Association and Corrosion Prevention Association.

The business operates as a traditional civil engineering contractor competing primarily through competitive tendering, framework agreements, and subcontracting to tier-1 contractors such as Kier Highways and LMJV (on HS2). Named clients include National Highways, HS2 (via LMJV), Sustrans, Railway Paths Ltd, Amey, Staffordshire City Council, and Dudley College of Technology. Project values disclosed in case studies range from £45k for small investigative works to £8m for the M6 R193 spaghetti junction repair programme. The firm holds a dense pre-qualification stack — ISO 9001/14001/45001, FORS Bronze (7 consecutive audits), Constructionline Gold, CHAS, Avetta, and full CRA/CPA/CECA membership — that underpins its eligibility for public sector tendering.

CLM is privately held with no disclosed funding rounds, acquisitions, or external investors. Revenue and pricing are not publicly disclosed. Operations are concentrated in the Midlands region of England, with project-led work elsewhere in the UK via prime contractor relationships. The firm maintains a directly employed workforce, holds Living Wage Employer and Disability Confident accreditations, and is a member of the SME Climate Hub committed to halving emissions by 2030 as part of the UN Race to Zero campaign.
