Core offering

Oliver Connell and Son is a UK-based specialist construction subcontractor delivering reinforced concrete (RC) frames, architectural concrete, basement and civil engineering works, aviation infrastructure, and rail/infrastructure projects. The company self-delivers using in-house labour, formwork systems, and a modern plant fleet, with RC frames representing approximately 75% of annual turnover. Services are provided to tier-1 main contractors, developers, and infrastructure clients across London, the South East, and nationwide for infrastructure works.

The company self-delivers projects using in-house labour, proprietary formwork systems, and a modern fleet of plant and equipment including tower cranes, mobile and static concrete pumps, and vacuum excavators. Services span groundworks through to superstructure completion across the residential, commercial, rail, and aviation sectors.
