D4S have provided us with structural verification services on a number of occasions which have helped us to secure some high level work as part of our design process. D4S quality of work is always of the highest standard and they can react quickly to our design needs which is one of the most important factors of the service they provide. I will be happy to continue using D4S structural design services for any future project which we are involved in.

Declan McDonnell

Residential Client

We spoke with D4S in connection with a residential extension that we had undertaken in the Summer of 2018. We initially went with D4S as they were recommended by a close friend, but we had never employed a structural engineering firm up until this stage - so it was rather daunting. From the first time we met with Jon, until the project was completed, he made the entire process so easy for us, timelines were always met, and we received a very professional service, At times they do use terminology and language that is alien to us, but we always felt comfortable asking Jon and his team to explain this in a language we would understand. After the production of the drawings and calculations, we assumed that their role had been completed. However, this was far from what happened. They not only liaised with the architect, but also when we had any "technical issues" on site, they were at hand to answer any queries that we had with the builder. I'm afraid that this seemed to be a regular occurrence at times, but Jon was always at hand to answer these queries. Overall we were highly impressed with the quality of the work produced, but also the service offered by Jon and his team. I would highly recommend them for anyone considering using a structural engineering firm that goes above and beyond.

Director - All Glass Systems

I would highly recommend Jon and his team. We have worked with D4S since their inception and found all members of the team to be extremely professional, highly experienced and most importantly approachable. As we work more closely with Jon and his team, we are both learning more about each other which has improved efficiency in the development and design process leading through to manufacture and installation. I would not hesitate to recommend their services to others.

A superb service provided by Jon and his team, I would not hesitate in recommending this company to any of my client bank, I’ve enjoyed the highly professional etiquette, and the system that Jon has in the several jobs they’ve worked on.

Innovation Manager - McAvoy Group

In particular our experience of working with D4S has been a great success, whereby we have been able to avail both structural design services along with the provision of a fully developed and ‘ready for manufacture’ structural steel model and drawings. The whole process of streamlining the structural design and fabrication level steel detailing together from a single ‘one stop shop’ has been a breath of fresh air, and has ensured that the McAvoy Group have significantly reduced the chances of data loss when using multiple sources to produce this same level of information. The proactive approach from D4S to agreeing and producing a design, that was right first time, brings added benefits to the McAvoy Group in respect to faster delivery of design for the overall project.

Jon has an exacting attention to detail and a proactive approach that encourages creative design. As an architect I find this informative. His comments will invariably get me to re-consider how I want the structure to look and allow creative collaboration to flourish.

Derek Veale

Contracts Director - Trueform

I would just like to express Trueform’s collective gratitude for the efforts and services provided by D4S recently in respect of a number of Trueform projects. Colleagues within Trueform’s specialist Design department have specifically expressed that working with D4S has been a smooth and efficient process. D4S’s professionalism and expediency has been essential when developing designs which are often innovative and built to tight timescales. The clarity of D4S’s calculations along with the executive summaries provided are refreshing when structures need to be quickly evaluated and the design developed. On a personal level, I wish to express my own gratitude to the speed and efficiency by which communications are responded to, which has become the expected norm in the world these days.
