Offaly Civil Engineering has been engaged on the Goulburn Murray Water Connections Project through John Holland to deliver a significant portion of works throughout 2 years on the project. I have found Garreth and the team to be professional, reliable and efficient in reacting to and delivering on a challenging project with a large number of stakeholders, whilst maintaining strict SQE standards as expected from a Tier 1 Contractor. John Holland are happy to continue our strong working relationship with the Offaly Civil Engineering team.
