19.4.6.1
Construction Time. Construction time for a Systems Module
building can be less than for a conventional building. With a walk-on
deck, trades can work concurrently in the occupied zone and the
distribution zone rather than in sequence as in a conventional
building. The majority of the work in the distribution zone can be
performed in a comfortable standing position on the walk-on deck
instead of from a ladder as in a conventional building. Repetition by
modular design and standardization of equipment can also reduce
construction time.

19.4.6.2
Construction Cost. The initial construction cost for a
Systems Module building can be greater than for a conventional building
due to the interstitial walk-on decks and increased building height.
19.4.6.3 Maintenance Cost. The maintenance cost for a Systems Module
building can be lower than for a conventional building when
accessibility to utility systems in the distribution zone is assured by
observance of the IBS Systems Module design concepts presented in this
section. Equipment is more easily accessed and workers are provided
maintenance tasks. However, there will be some added maintenance cost
for the distribution zone, i.e., lighting, walk-on deck and access
aisle repair, fireproofing repair or replacement, etc.
