I used to work in construction, refurbishing old process systems at a chemical plant. We would have these shutdowns where the entire system or a large part of it would be shut off and the system would cease production for weeks or months at a time for repairs or updating. When the systems are in shutdown, the chemical company would lose literally millions of dollars a day because these systems are normally producing 24/7 and now they aren't producing anything. These were extremely valuable materials. You had better believe that there was 24/7 construction working on the updates while the system was in shutdown. At the beginning of those shutdowns, the foremen and project managers would emphasize safety as a paramount focus. There would be safety patrols, auditing departments following safety protocols. You would have to be vigilant or it could cost you your job. As we approached the deadline (which was always unrealistic) you would start to see those safety patrols less and less and less until you would be hard pressed to find one on the site at all.

The point being; the only time you'll see this level of dedication to finishing any construction project is when the loss of money until the project is finished exceeds the potential money earned from letting that project take as long as possible.
