Design Evaluation
Architect: • Concept fits local area• Less visually pleasing
Engineer: • Rigid diaphragm problem
Construction Managers: • Best budget
Architect: • Best looking building
Engineer: • Girders have deflection problem
• Sloped roof helps snow load
Construction Managers: • Very constructable & best schedule
Alternative 1 Alternative 2
Design Choice
Alternative 2 Best combination of strengths vs. weaknesses
Wood / Steel Hybrid Combine the attractiveness / interest of 2W with the cost and
schedule benefits of 2S
Keep wood exterior structure of 2W, but incorporate the steel interior structure of 2S
Design Vision Concepts
Box in a box Simple, double structure
Advantageous use of sloped classroom and auditorium floors
Flow of light to below grade level
Exterior wood structure to gesture towards trees
Floor Plans
Auditorium
Classrooms, seminar rooms, labs
Student offices
Faculty offices, facilities, administration
Engineering Constraints
Soil Properties Compactable Soil 4000 psf bearing capacity Capacity, silt/clay and sand mixture 20’ water table
Loading Live Load 50 psf
Dead Load 70 psf

Roof Load 28 psf
Outside Frame Plan
Pre-fabricated wood truss with knee brace
Prefab wood truss 2"X6“ @ 24”Column 12"DIAKnee brace 2"X6"Joist 2"X4"
Site Layout Crane:
Arm Length = 106 ft
Construction Road:
280 Feet Long
Trailers:
Located at Entrance
Safety:
Trailers & Toilets Not in
Crane’s Radius
Constructions Methods
Simultaneous Erection of Interior and Exterior Structure
Prefabrication of Roof Trusses
Work Sequence From the Center of the Building
to the Two Outside Parts of the L-Shape
-> Better Material Flow
-> Simultaneous Work Opportunities

Team Process
“The process can be frustrating. We should always bear in mind that the other parties are not our enemies. We have the same goal, to design the building. Don’t let it get too personal, use the communication tools provided in this class, and then less frustration will occur.”
“After getting to know the other’s expectations and concerns better, we handled all issues much easier, faster and more effective during the spring quarter by anticipating everybody’s opinions and, therefore, avoiding problems even before they arose.”
“This spring we not only worked more thoroughly but understood that every detailed decision in one discipline in turn impacted the other two disciplines...Continuously iterating as we proceeded with the project”
Lessons Learned Cross-Discipline Knowledge
Objectives and Concerns Different and Discipline-Based Development Habits
Teamwork Efficiency Reliability Organization / Work Habits
Technology New Hardware & Software More Effective Use
