activities such as workmanship, adherence to design,
cost, and schedule conformance.
5.1.13 contingency — a reserve of funds, time, and/or
material that is allocated to maintain schedule and
budget. A reserve for scope changes, unforeseen site

activity is complete when all of the following are met.
• The equipment positioning and bolting down is
complete.

installation process that follows base build and precedes
tool hookup. Prefacilitation brings the various facilities
services close to the new equipment location, including
new facilities services and structural modifications
required to prepare the facility to accept the equipment.
Also known as rough-in, this step is performed as a
time-saving operation. The activity requires the
following conditions to be met:
• The raised floor is in (if required).
