Program

• Student teacher ratios

• Schedule/occupancy expectations

• Curriculum expectations/offerings

• Arts, Activities, Athletic offerings

• Site, pools, auditoriums, spectator

counts, support

• Food Service expectations

• Technology

Budget Variables that Effect Cost Models

Climate/Geography• Footings, soils• Interior or exterior hallways• Mechanical systems• Insulation/vapor barriers• Wind/structural/storm/seismic• Roof/enclosure specifications

Budget VariablesCompared to National project data base

•Reputation as Leaders in Learning, facilities that support that ambition

• If national recognition is to be pursued it will be for the assimilation of design as it supports the pursuit of the learning program

Quality/Aesthetic and Life CycleWDM Design Guidelines


Quality/Aesthetic and Life Cycle

• Energy efficient

• Sustainable, Durable

• Long Term Pay Backs

•Materials selected for their “Timelessness”

• Foundations and Substructures

• Superstructures (columns, beams, etc)

• Exterior Enclosures (“skin” ) Roofing

• Interior Construction (walls, ceilings)
