    Deductive Change Order and Overhead

    We are issuing a deductive change order. And the contractor is not including the overhead and profit in the cost proposal. Our argument is they should because in the contract, it reads the following: "For Work to be deleted by Change Order, the reduction of the Contract Sum shall be computed...

    Unforeseen Condition Delay

    We went back through the geotechnical reports and actually found that it indicated boulders and concrete in 1 of the reports. Sorry for this late information and not sure if it changes your opinion but appreciate any additional feedback. And to clarify, they did not bring in new equipment...

    Unforeseen Condition Delay

    coloeng So far the contractor has spend 19 days working against 49 days estimated on the baseline schedule. The condition thus far is a lot easier than they had thought. I overheard them joking the soil is like "yogurt". So is it reasonable to take this into consideration.

    Horizontal Drilling Heaving

    This is a sewer line and it is 20 ft deep to avoid existing storm drains. Does the heave seem possible considering the bore is 20 ft deep?

    Horizontal Drilling Heaving

    A contractor on my project was using horizontal drilling to pull a fusible pvc 20 ft deep in the ground. As they were pulling, drilling fluid came through the existing joints along an old trench. And supposedly, the ground heaved 1". My question is it possible for the ground to heave when the...

    Horizontal Drilling

    I have a project where the contractor is using Horizontal Driving to install fusible PVC in the ground. During the reaming operation, they were running into rock which damaged their drill bits. Now they are claiming cost for repair to their drill bits and delay in their operations. There was...
