19.4.6.4 Flexibility for Modification and Alteration. Most medical
and medical research facilities undergo frequent and significant
modification and alteration during their lifetimes. In a conventional
building, such changes normally result in extensive utility disruption
for other areas due to the need to upgrade or modify systems.
Typically, a Systems Module building modification requires only changes
to distribution zone utility systems and equipment serving the portion
of the occupied zone undergoing change, resulting in a simplified work
effort and less disruption to the ongoing building function. Systems
Module buildings inherently provide capacity for future expansion, load
growth and modification, often without requiring costly primary and
distribution equipment upgrades.
19.4.7
Systems Module Documentation and Construction Considerations.
19.4.7.1 Construction Documentation. Drawings for Systems Module
buildings shall include plans and sections delineating utility
distribution channels in each distribution zone sub-zone. Drawings
shall be coordinated with all disciplines. Interdisciplinary cross-
sections at critical locations, i.e., above operating rooms, equipment
rooms, corridors, etc., shall be provided. Requirements for
coordination of all disciplines prior to construction shall be included
in all pertinent specification sections.
19.4.7.2 Pre-Bid Conferences. To ensure that construction contractors
take the IBS Systems Module design concepts into account when preparing
bids, presentations of these concepts are recommended for pre-bid
conferences conducted by the Government.
19.4.7.3 Pre-Construction Consideration. For a Systems Module
construction project, a sample distribution zone, at least 93 m2 (1000
ft2) in area, should be constructed at the project site. The sample
should include a complete walk-on deck assembly with suspension
members. The sample should also include elements of the utility
systems within the distribution zone. Construction of the sample
should be sufficiently in advance of building construction to allow
time for necessary testing and approval. Various construction details
can also be addressed and finalized with this sample, i.e., temporary
protection of the walk-on deck during construction, proper support and
sealing of ducts and fire dampers at walk-on deck penetrations, and
permanent fire sealing of the walk-on deck to abutting walls and other
permanent structural elements.
