Tercon

What Tercon does

Tercon Ltd. is a privately held regional civil engineering and building contractor headquartered in Avonmouth, Bristol, founded in 1960 and operating since 1977 as a limited company. The company employs 51-100 people and delivers turnkey main contract civil engineering, commercial and industrial building, and specialist groundworks sub-contract services across the South West of England and South Wales, generally within a 50-60 mile radius of Bristol. Its service portfolio covers road and development infrastructure, service mains, environmental and landscaping works, retaining structures, heavy goods roads, distribution warehousing, specialist process buildings, factory units, offices, and waste/energy utility infrastructure, alongside a dedicated Small Works team handling projects from £5k to £500k for repeat clients.

The business operates a direct delivery model underpinned by an owned plant fleet, experienced site supervision and a dedicated management team. Tercon works both as a main contractor (design-to-completion civil engineering and design-and-build commercial/industrial projects) and as a specialist sub-contractor to leading UK contractors. Notable technical achievements include a 1,450m3 continuous 24-hour Strongfloor concrete pour at the Airbus Wing Integration Centre in Filton — believed to be the largest single concrete pour in Bristol and the first of its type in Europe. The company is a member of CECA South West and maintains a comprehensive UK construction compliance and accreditation portfolio (ISO 9001:2015, CHAS, SafeContractor, Constructionline Gold, Achilles UVDB, BS8555, Altius, CIPS Sustainability Index, CECA, CITB, CSCS).

Tercon generates revenue through project-based, one-time contracts won via single-stage competitive tender, two-stage tender, and negotiated processes. Customer segments include major UK contractors (Galliford Try, ISG, Bowmer Kirkland, Wates, Willmott Dixon), private developers and corporates (Airbus, Thatchers Cider, Viridor, Air Liquide, CNG, Legal & General, Nisbets, Vanguard, LSS, Dyson, AB InBev, National Windscreens), and utility/education clients (Bristol Water, University of the West of England). Marketing is conducted primarily through direct business development, competitive tendering, and a company website with project case studies; the firm maintains a LinkedIn presence but has no disclosed paid digital marketing channels.
