Report
3S have been a fantastic partner during our recent expansion. They have managed the site, all of the trades as well as being the electrical contractor during the fitout of our new 25,400 sq ft facility.
Highlights have been a 60 dBA, 25m x 15m x 9m acoustic wall, bespoke concrete trenching with footplates, lots of unusual high power electrical requirements and 100m of perimeter fencing. Nothing was too much trouble even when we had to make changes part way through the project and this all happened during the coronavirus pandemic. I would recommend 3S as they are very flexible, friendly and you
