The stadium project needs each document logged, indexed and accessible. Information flow is crucial, and delays cost money. In the event of a crash, Douglas can recreate a system from hard copied, but that process is lengthy and therefore expensive. Losing a server with critical information can mean the difference in whether concrete gets poured or steel goes up. Each contractor and subcontractor bids for jobs based on estimated costs, and each project phase is tightly scheduled.
Any delays snowball through the system, affecting everyone.
Protecting it is a priority, and can be tricky given the construction environment's special threats. Sites are dirty and wet. Trailer roofs and windows leak. The unavoidable dust settles, and pile drivers shake buildings. Douglas isolates servers in a room he can somewhat control, but that control is limited.
