Fabrication shop inspection is different from construction site inspection
in many ways, but probably the most important one is the chaotic and random
nature of on-site field construction. Different crafts do different trades,
and do not care a damn about the other. Get in, get out. In spite of great
effort, a lot of construction is ahead of or behind schedule, sometimes both
at the same time. The bigger the job, the more out of control it is. There
will be crafts that the superintendant does not know are working. Many
times, subs do not show up. Frequently, structural problems (the most
important-architectural problems we have some slack with) will hold up many
others, so the pressure is on to let it go as is. This pressure goes right
up to the top-owner, engineer, architect. Time is money. Make it work.
Revise the calcs.

Other than the Pyramids, does anyone think a project was ever built as planned?
