Simmtronic have delivered a large number of technically challenging projects for DBS and consistently continued to provide outstanding service. Their support, guidance and help throughout the process has been exceptional, working closely with our design teams to ensure the right solution for the project and a sound understanding of the brief, with our delivery teams to ensure the installation and commissioning are trouble free and then providing fantastic after care to the customer. They have added true engineered value into the projects they have been involved in for Derry Building Services.

Over the years I have really appreciated the Simmtronic ability to provide responsive support and listening to projects and clients needs. More recently the Simmtronic team has shown the capability to embrace the connectivity requirements of the Internet of Things by quickly adding MQTT to their range of integration protocols. This will greatly facilitate telemetry applications in buildings and the development of interconnected solutions that will make buildings more usable and easier to operate.

Simmtronic as an organisation has been, for the last 18 years, by far the best performing and most reliable lighting control system I use. From design through to commissioning and soft landings with the landlord teams Simmtronic always deliver on my projects. Simmtronic technology evolution is not just pushed through like others, but rather properly tested internally first, giving us as client teams the assurance that what Simmtronic say they can offer is 100% delivered, an absolute must with fast track major projects.

Simmtronic has constantly been available at an early stage to engage both with the designers and the Contracting team to assist with design solutions and to test options. This ultimately assists us in de-risking the project during the commissioning phase which usually defines when the project is completed. Simmtronic is seen as ‘industry standard’ and it is always encouraging to see them involved.
