You are building a mile-long bridge on a T&M contract. During the excavation activity, you learned some telephone cables are crossing the alignment where you have to construct the bridge. You need to relocate these telephone cables, but there is no provision of such an activity in the contract. Further, the relocation of the cables is a costly task, and you need to do a lot of government paperwork, as well. You requested an amendment in the contract, but the buyer rejected it. Despite many efforts, you both could not resolve this issue. What should you do next?
