I, like many of you at some point or another, am not being paid for a rock job I'm on. I hit rock in the middle of december on a mass grading job I'm working on. There are NO geotech engineering reports to my knowledge so the job certainly isn't classified. The owner's engineer is the 3rd party representative throughout the process and has been quantifying the rock. I've taken a number of pictures of the dozer ripping the material and the smoke flying off behind the dozer. However, the GC on the project claims I only experienced 'delayed excavation' and will not be paid for any rock. This seems like a fancy way of getting around a rock clause. Is this typical and I'm just missing the boat here? I've completed a number of jobs in which I charged for rippable rock. The engineer's field reports even classify it as rippable rock. The GC is denying the change order with a claim that rippable rock is, as a standard practice, not beyond the project scope. Am I missing something here? Please advise.
