I would like to express my personal thanks and appreciation to JJ MAC (John, Pat and their site team) on the good and hard work they have carried out for Decoy Industrial Estate Link Road which was part of the A380 South Devon By-pass between November 2014 and May 2015.

This has been the first time I have worked with them and found them to be a very hard-working, safety conscious and organised team. Also, I have been very impressed with the way that they approached work and followed relevant site instructions where and when considered to be appropriate.

I highly recommend them for any similar future work in your company and I’m sure that they will do a great job and would be a great asset to be working with.”

On behalf of the client and HPC Homes I would personally like to thank you for all the effort that you and your work force put in on one of our more difficult contracts. JJMac completed the project in a professional manner, within budget and working to our unrealistic timetable. Jason Dixon

Construction Manager, HPC Homes Ltd

Thank you for all the hard work. I am very pleased with the final results and I was exceptionally pleased that we came in on budget and a week ahead of schedule. Robin Immink
