Value Engineering § Systematic process to balance cost, reliability, and Performance § Must be started at same time the design is to maximize value § Analyses the functional requirements of the project to maximize the budget for the entire life cycle of the project including initial cost, operational cost and maintenance cost § The process involves five phases: Information Phase, Speculative Phase, Analytical Phase, Proposal Phase and Final Report Phase.

Example of Fast Diagram

Code Requirements § BOCA National Building Code states Type E (Educational) User Group § Type II B construction §The IBC states that a sprinkler system is needed when a structure is 20, 000 sq ft or more for Type E User Groups §Height and area limitations §Without Sprinklers: Two Stories at 14, 400 sq ft/floor §With Sprinklers: Three Stories at 44, 800 sq ft/floor

Proposed Structural System Structural Steel § § § Radius Cost: $414, 192. 59 Admin Cost: $339, 066. 21 Total Cost: $753, 258. 80 Advantages § Minimized construction time for two story building § Erection of steel is very fast § Can be preformed in more adverse weather conditions Disadvantages § Lead time

Proposed Roof System § Cost: $174, 336. 38 Description The steep slope will be 24 Ga steel metal roof panels The low slope will be two layers of 2” ISO with fully adhered PVC membrane Advantages § Great reflective surface 90% of suns heat § Long Life span § Double layers of ISO allow less heat lose through roof than single layer Disadvantages § None are known

Proposed Building Skin Brick/CMU Backup § Cost: $671, 523. 99 Advantages § Long life span § No need for replacement § Increase thermal efficiency Disadvantages § Risk of mortar cracking due to settling
