I have a mowing contract with the military. They are very specific about areas to be mowed and how often. They specify in the bid documents to visit the area for an inspection before bidding. Here are my issues. 1 They have added through new seeding about 1 acre of lawn. 2 They have constructed a horseshoe pit that was not there when I bid it. 3 They have contructed stairs on a hill that are 20x100 ft. This makes for more trimming in addition to another obstacle to avoid. 4 They have installed a 36 hole disc golf course on the property. This has created mor things to trim around in addition to people to avoid. 5 They have changed the grade of some areas through the new construction to make it so I need to use a string trimmer where I used my walk behind. I could go on for at least 10 more line items. The bottom line is that The park manager does not want to pay me more. I have refused to trim the new obstacles and I have refused to mow the new areas. Can I just walk away? Go over his head? Anyone else have to deal with this?
