Civil and Structural Engineering Consultancy. We design structures and site infrastructure on projects throughout Ireland. At NJD Consulting Engineers Ltd., we utilize the latest digital BIM technology to produce our civil engineering and structural engineering documentation. This results in less queries coming back from site, leading to better cost and schedule certainty for clients and contractors. The BIM tools we use include Autodesk Revit, Civil 3d, Navisworks, and AutoCAD. The practice is led by Niall Dennehy, a Chartered Engineer with 17 years experience working on engineering and construction projects locally and internationally. Niall has a first-class honours degree in Civil Engineering from University College Cork and a postgraduate qualification in Professional Engineering from Dublin Institute of Technology with a focus on Project Management.
