Later today, we're headed back to City Hall to pick up our revised plans because of the truss manufacturer "issue". (We didn't know we were supposed to have told the engineering firm that we'd have someone else make the trusses.) In the end, we spent a little more than $300 in order to save $100.
But, we learned a valuable lesson. Ask questions like, "How much is this going to cost us if we do this?" and "Is there anything else we'll need to do if we do X?"
On the plus side, the trusses should be inspected tomorrow and be ready for a roof to be installed.
