Part of the Byrne Group

Byrne Groundworks is proud to be part of the Byrne Group, working alongside Byrne Demolition, Ellmer Construction and Byrne Bros. Together, we offer clients a fully integrated service across demolition, groundworks, concrete frames, construction, and fit out. This joined-up approach means fewer interfaces, smoother transitions, reduced risk, and greater programme certainty — from first clearance to final completion.

Our Reputation

We’ve earned a reputation as a trusted partner for main contractors and developers by:

  • Delivering complex groundworks packages safely and on time
  • Applying technical expertise to minimise risks and delays
  • Building long-term client relationships through reliability and trust
  • Contributing to some of the UK’s most iconic projects, including the Olympic Park, Battersea Power Station, and Wembley Park

Our History

Our story began in 1970, when Patrick O’Keefe Sr. founded O’Keefe Construction with little more than determination and a dedicated team. His early adoption of specialised plant machinery and pioneering soil stabilisation techniques set new industry standards in safety, accuracy, and efficiency.

This spirit of innovation continues today at Byrne Groundworks. As part of the Byrne Group, we combine decades of experience with modern methods and sustainable solutions—ensuring that every project we deliver is built on strong, reliable foundations.

Our Values

Our work is guided by a clear set of values:

  • Safety first – protecting people and projects at every stage
  • Precision & quality – ensuring accuracy and efficiency in delivery
  • Sustainability – reducing environmental impact through modern practices
  • Collaboration – working closely with clients and sister companies to deliver seamless solutions
