I brought a valued engineering idea to the table saving the owner $200,000 six billings into the job the GC says I must give back the deduct from my job. Here are the numbers Orig Contract 1.9 mil VE Contract 1.7mill New net invoice is 1.7 mil 6 months into billing I the GC for 300K he states that I will only be allowed to bill for 17k because I need to start paying towards my deductive change order and now is a good time to do so. The GC is willing to 17k. If I don't like it I can wait until next billing period. Is this legal and can he make me pay for monies I never received?
