  • Experience with HCSS Heavy Bid, Bluebeam, Excel, AGTEK, or similar estimating/takeoff software preferred.
  • Strong cost-management and project financial skills.
  • Bachelor's degree in Construction Management, Civil Engineering, or a related field preferred, but equivalent heavy civil experience will be considered.
