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.” JJ Mac Ltd is a Lincolnshire based Civil Engineering, Earthworks and Groundworks Contractor delivering services nationwide.
