Construction and Engineering

The Practice

Arthur Cox is one of the few Irish law firms to have a dedicated team of construction and engineering law specialists, offering expert advice to all parties involved in construction and engineering projects in both Ireland and Northern Ireland. Our Construction & Engineering Group combines contentious and non-contentious expertise and we understand the ever-changing commercial objectives of our clients.

The Construction & Engineering Group sits within the Infrastructure, Construction and Utilities Group and is headed by Niav O’Higgins who alongside Karen Killoran works with a strong team of Associates and Consultants. All members of the Group are industry specialists and draw on a wide variety of skills and experience from both within the Group and from other groups within Arthur Cox.


The Construction & Engineering Group advises on issues arising throughout all stages of a construction/engineering project and in conjunction with other specialist teams, advises from project inception, planning, procurement, project execution, project completion, building regulations, health and safety and the resolution of any disputes. We assist clients in balancing risk and opportunity to achieve their commercial objectives on time and within budget. We co-ordinate our knowledge and experience to work as part of the multi-disciplinary team engaged on each project, with the focus on facilitating the smooth delivery of projects.

We also advise on contentious matters which can arise on a construction project with particular focus on promoting early case assessment and effective dispute resolution strategies for our clients. We advise on all forms of ADR including mediation, conciliation, expert determination, adjudication and arbitration, as well as advising in High Court and Commercial Court proceedings. We also represent clients in health and safety matters, including defending enforcement actions brought by the Health and Safety Authority.

The Construction & Engineering Group works closely with the Project Finance, Environment, Planning and Climate Change, PPP/PFI and Energy & Natural Resources Practices and has been involved in the majority of PPPs, and other major infrastructure projects in Ireland.


Our experience spans a breadth of sectors, including process engineering and manufacturing, life sciences, healthcare, education, renewables, energy and natural resources, transport, education, water and wastewater, commercial development and general infrastructure sectors. Our clients include employers and developers from the private sector, contracting authorities from the public and semi-state sector, contractors and sub-contractors (acting individually or in a consortium), professional construction consultants, insurance companies, receivers, liquidators and funding institutions.
