About Project

This project has been selected as a Public Sector Retrofit Pathfinder Project and we are proud to have been appointed on the Office of Public Works (OPW) to this prestigious project. The completed project will be an exemplar, energy efficient, State office for occupation as a Headquarters Building by the lead Irish Government Department on the environment – the Department of the Environment, Climate and Communications. The works will consist of a significant upgrade to the 1970s building thermal fabric and overall energy use – that will upgrade the Building Energy Rating (BER) from a G rating to an A2 rating, resulting in an 85% reduction of annual energy use and will greatly extend the buildings useful life.

The refurbishment will retain the existing 1970s structure, taking advantage of the energy already embodied in the concrete structure and brick external façade. By retaining and upgrading these resources rather than demolishing and rebuilding, the works will have significantly less impact on the carbon footprint of the building. Internally, the existing cellular office layout will be modified to a more open plan arrangement, increasing the overall building occupancy,  while the introduction of a new central floor void will create improved daylight and natural ventilation conditions.

Reduced Costs
Reduced Reworks
Less Time Onsite
Kieran Murphy, Project Manager
I've worked with DCT on a number of commercial and industrial projects to date and I'm more than happy with their performance. Keith, Owen and Graham, have an in-depth knowledge of Mechanical and Electrical services and produce an excellent fully co-ordinated BIM model, with dimensioned drawings that are easy for Tradesmen to read, and install too on-site. They are always available for meetings, can take the lead, seeking clarification, while raising RFI's for clarity with the Design Teams. I would highly recommend DCT for any BIM/Co-ordination drawings required for M&E projects.
