Hi Justin, just wanted to say a big THANK YOU to you and your team for  all the great work you have done on our Project . Being the biggest Civil project in the country we have no room for error, and working in the Auckland CBD certainly has thrown us a few curve balls when it has come to Utilities. Thanks to the in depth knowledge and detection skills of your team, we have found Sub Surface Detection to be a valuable resource and our  “go to “  contractor for any mark-out and detection of known, or unknown services in the area . Whether it is a mark out of a cable, or to detect depth and direction of a duct, you have always given us very prompt, efficient and an accurate mark out .  I can’t recommend you highly enough. Once again, many thanks.

This is to thank you and your team for the great work you did on the above project. You achieved everything asked, on time, and on budget. The results exceeded our expectations and were essential to achieving our objective. We’ve had great feedback about the work and there seems to be a general acceptance by management that using a contractor is the way to go.

Jonathan – May 2017

We just want to take the opportunity to praise the staff member who attended our property. He was professional, courteous, well informed and presented us with exactly the information we were asking for. Of course you would expect that but, the manner in which he performed his duties was exemplary. You are fortunate to have such an employee.
