We were installing a french drain system in a basement and discovered that their footing is inadequate and requires reinforcement before we contin ue work.
Client insists that it is our responsibility to reinforce footing since we opened up the trench for the french drain and it is no longer virgin soil.
We feel that since they knew (they admitted this) about this problem but did not tell us about it before we started excavating, it is their problem and our contract states that any problems found that comprimise the structural integrity of the workspace (which this obviously did) will incur additional fees.
We feel like we are being taken for a ride since they knew about the problem and didnt tell us about it ahead of time.
What would you do? (we're waiting to see what lawyer says but client is going nuts and threatening just about everything at this point)
