For landscape managers, job bidding is tough. Bids have to be low enough to get jobs and high enough to turn a profit after covering costs. That makes cost estimating even more critical, especially for beginners who have no benchmark data to base their estimates on.A University of Georgia workshop, offered in Savannah Oct. 18-19 and Athens Oct. 25-26, will make it much easier. The workshop will introduce managers to “Hort Management,” a computerized cost-estimating and job-bidding module developed by UGA faculty.Participants don’t have to know anything about computers. With hands-on instruction, they will learn: Even people who don’t bid directly on jobs will find the program useful in estimating labor costs, time and task data and cost comparisons.The workshop is limited to the first 28 people who register. The $60 fee includes a copy of the $50 “Hort Management” program, lunch the first day, refreshment breaks, handouts and personalized instruction.The deadline to sign up is Friday, Oct. 12.
