This happened a few years ago in Louisville, KY.
My company had the contract for a building at the University of Louisville. Min conduit size was Âľâ€ť. Slab roughed on Friday, top layer of re-bar too high. Engineer said remove Âľâ€ť and change to Â˝â€ť in slabs. He said weâ€™ll work out the change order later. We removed the Âľâ€ť and installed Â˝â€ť on a Saturday to ready for pour on Monday.
Several months later I was in the engineerâ€™s office to finalize several items and changes. When I brought up the conduit change he said â€śYou got anything in writing?â€ť and refused to OK the change.
A couple of years later, we had another project where the same engineer was involved. This was a retrofit of central HVAC units to several connected buildings. The specs had each of the 8 buildings as alternates. All service originated in building 1, rose to the roof, and was distributed from there. The plans for the alternates clearly stated â€śâ€¦all work on these plans for building (X) shall be alternate (X). Building 3, 4, and 5, were not accepted but 1, 2, 6, 7, and 8 were accepted. We ran the feeders for buildings 6, 7, and 8 to the edge of building 2 and terminated. We went to building 6 and completed the feeders for 6, 7, and 8. The big gap of buildings 3, 4, and 5 had no feeders. (Feeders were 500MCM in GRS).
In a meeting the engineer admitted his goof and said go ahead, Iâ€™ll issue a change order. Not to be burned twice, I declined and said I would put together a price and wait for a change order.
To shorten this a bit, I got triple what I would normally have received and later I told the jerk, â€śRemember the U of L project? Well, I just got my money back 10 times over.â€ť
