We really enjoyed working with Matthew Lee, and hugely appreciated the speedy, professional and efficient way the reports were completed & sent onto the bank. Thank you Matt!

Since taking the position of Managing Director of PAC Architects in 1999. We find that CPSQS are generally very accurate with Cost Estimating, no doubt as a result of their intimate knowledge of the Papua New Guinea Building Industry. Although a business association, I have thoroughly enjoyed the congenial approach and unflinching willingness to help. I count the current CPSQS Team also as good friends.

Gregory James Runnegar | Managing Director

Since our first project with Costplan Services albeit small, gave us a good indication of what Costplan Services could bring to the table, the service we received impressed us and our clients. It was far more robust and professional than we experienced with our estimating surveyors and more user friendly than larger Quantity Surveying practice that we would normally work with.

John Harmer | Director

I was extremely pleased with the level of service that I received from Costplan Group. Their professional, but personable approach helped me to resolve a potentially difficult situation. I would have no hesitation in recommending them.
