BUILDING SCHEMATIC DESIGN (BLOCK LAYOUTS)
432.1
PLANNING
Matching exact departmental area requirements to service module and fire
section boundaries is the key activity in this phase. Departmental
requirements for proximity and growth capability must be carefully
considered in establishing the arrangement of vertical and horizontal
circulation elements. The site plan must be completely coordinated with
internal circulation patterns in terms of vehicular approaches, parking,
emergency access and connections to existing buildings.
432.2
BUILDING SUB-SYSTEMS
Generic design options for the structural, ceiling and heating-ventilating-
cooling subsystems must be evaluated and selected during this phase.
(The plumbing and electrical sub-systems do not have generic design
options, and the selection of a partition option can be postponed until after
start of working drawings.) Critical dimensions, such as beam spacing,
service bay size and shape, shear wall and construction joint locations,
and the sizes of shear wall and diaphragm penetrations, must be
established. (See Sections 313 and 316.) Floor-to-floor and overall
building heights can then be determined on the basis of the functional
zone and service zone heights required.
Available building products must be evaluated to allow development of a
movement systems strategy as well as a rational selection of generic
design options for the integrated subsystems. If new product development
seems appropriate, the feasibility of satisfactorily completing a product
development program within the scope of the project budget and schedule
must be studied. (See Section 764.)
432.3
COST AND TIME
Alternative construction process strategies must be examined in the
context of the current schedule, and the schedule revised if necessary to
optimize the process. Cost estimates must be prepared to assist in this
analysis, as well as in the final selection of a specific design configuration,
building subsystem options, and a transport system strategy.
