David has a background in construction. He started in the trenches on the tools, working his way through an apprenticeship. He soon discovered that he was more suited to management, so he became a site manager for a light commercial building company. He then started working for a construction company with a friend. The two of them undertook a 300-panel precast project. David managed 15 staff members and materials, as well as ordering ahead to stay on schedule. After completing the panels, he transitioned back into the residential market as being a subcontractor was no good there.He got familiar with sales and marketing, along with tendering for projects averaging $10,000 - $100,000 . Very quickly, David realized there was an opportunity in a smaller market with much more volume—margins were better there than they were in commercial construction.

In 2021, David bought a profit-share partner to run the company and transitioned into QS work full time. Since then, he has been pricing over 2,000 projects for other building companies by making spreadsheets look jargon-free and easy to read.
