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.
