About Us

GNCE are Consulting Engineers based in Dublin 2. Service is based on Glenn Nunan’s and Terence Sweeney’s extensive experience and reputation built over many years in the Construction Industry, offering both Mechanical/Electrical & Structural/Civil Engineering Services.


GNCE's Design Strategy is based on our extensive experience and reputation built over many years in the Construction Industry. All of our projects incorporate low energy technologies, when combined with high performing building fabrics, result in an inherently low energy use building.

We apply the technology in an appropriate manner based on sound engineering. A building is not a single part but the sum of all the parts which achieves the desired total. This is a very important part of the design approach.

As a designer, everybody on the project has to work together to make the building as a system, work successfully.


Our methodology consists of 5 steps as follows:

1. Preliminary – Discuss brief with Client and Architect so that all aspects of the project are outlined from the start.

2. Concept Design – After discussions with the Client and Architect, the concepts are put on paper which display the different innovative, low-energy options available.

3. Tender Design – Drawings and documents are created for issue to various sub-contractors for pricing purposes. On receipt of these prices, a thorough analysis is prepared and then reviewed and discussed with the client.

4. Construction Monitoring – Work has begun on site and so the involvement with meetings and inspections for the compliance of BCAR is undertaken. Procurement submittals are processed and issued to the client for review and any issues on site are dealt with.

5. Construction Handover – In this final step, all final certificates are collected and inspected for the final project documentation. Compliance with BCAR is upheld through final inspections and handover to the client completes the project.


With our experienced staff, GNCE has the necessary Technical and Computer Modelling resources to handle the most complex of projects.

We have expertise using the following Building Information Modelling (BIM) software tools: Revit, MagiCAD, iSBEM and Autodesk MEP to manage the construction and provide models to allow informed decisions to be made.
