I spent a few hours today assembling and installing four light fixtures. The owner didn't want them installed as the manufacturer intended, and wanted them on the wall instead of the ceiling. It took a lot of custom work. I'm not complaining because it was T&M, but there have been other situations where it was a contract.

Usually I just eat problems like this in contracts. I normally allow a little extra time for SOMETHING to take longer. It may mean a little more or less profit in the end, or even go without profit and cut into the hourly rate. I figure it all evens out at the end of the year.

I'm just curious how other guys handle this, usually with cheap fixtures, but I've also had bad mudrings that had to be tapped out. Do you word the contract that this would go into T&M, or as an extra?
