In 1992, Thomas G. Duffy established a civil, structural and traffic engineering consultancy and road safety auditing company based in Ireland. Following its establishment in 1992, DCE became one of the most successful multi-disciplinary engineering companies in Ireland specializing in niche markets such as Timber Frame Structural Engineering and Traffic Engineering Design Services. DCE’s continued success allowed the company to grow and in 2008 DCE’s first overseas office was established in Abu Dhabi, UAE. Following its success, a second overseas office was established in Doha, Qatar in 2011.

DCE provide civil and traffic engineering consultancy services, working closely with the other members of the design team to provide a cost effective design solution to the client’s requirements. Our highly skilled and experienced team of employees including, chartered engineers, senior engineers, CAD technicians and administrative staff, offer a quality service, quick turnaround times and all projects include professional indemnity insurance cover.

As recent years have seen a marked increase in planning authority requirements for Traffic Impact Assessments and Road Safety Audits, DCE has invested heavily in training and software geared towards Transportation Impact Studies, Traffic Impact Assessments and Road Safety Audits. With experienced traffic engineers, DCE can perform analysis of priority, signalized, roundabout and grade-separated junctions. DCE have successfully completed numerous Traffic Impact Assessments across Ireland, Qatar and the UAE having pre-qualified with the Abu Dhabi Department of Municipal Affairs and Transport and Qatar’s Ministry of Transport and Communications to carry out such studies.

DCE can also perform concept, preliminary, detailed and pre-opening stage (Stage 1, 2, 3 & 4) Road Safety Audits. DCE have conducted Road Safety Audits at all stages for the expressway program and local roads and drainage program throughout Qatar.

At DCE, our employees are encouraged to develop their skills by a policy of continual professional development. We aim to create an environment of developing and learning for the benefit of all.
