Picture C • Budget - $5. 5 M • Timeline – 1 year • Faster • Cheaper • Life cycle cost savings Construction Issues Objectives
Picture C Construction Issues Site Plan • Bonus double access roads • Can divert traffic if needed and use the other side of the road • Mobile crane
Construction Issues Picture Equipment C Pump Truck Based on capacity and availability Capacity 1. 54 cubic meter. Boom – 54 m Hauling Truck Reach curve
Construction Issues C Sequencing
Construction Issues Picture Schedule Milestones C Start Substructure complete Mar 1, 2015 May 4, 2015 Framing complete Sep 27, 2015 Dec 13, 2015 End
Picture Construction Issues C Schedule Analysis • Project Duration – 9 months • Resource allocation considered • Snow season- December 15 th to February 15 th • Steel procurement lead time
Picture Construction Issues C Total Project Cost = $5. 29 M (3. 38 M in 2001) Cost Estimate
Picture Construction Issues Cost Analysis C EIFS vs Concrete Panels: EIFS • $ 22. 5 per sf • Fast to erect • Good thermal insulation and immune to cracking Concrete $25 per sf Impacts schedule Sturdy but is labor intensive
Picture C Construction Issues MEP Issues Concerns • Head Room – Floor to floor heights? • Location of MEP room • Choice of a centralized vs distributed system
Picture C Construction Issues MEP Design • Cores used for risers with diameter of 24” • Distribution at center brings used air down • Fresh air distributed through the lateral cores. • Duct sizes • typical rooms 14” • auditorium 18”
Picture C Construction Issues Floor Systems Comparison Raised Floor System – Benefits and Disadvantages • Improved efficiency • More effective • Allows great deal of flexibility • 1. 25 times cost of conventional system

Conclusion AEC Working together, we were able to design a building that: • Closely meets the program requirements • Functions well as a learning facility • Responds to the site • Has a fairly low-life cycle cost • Is adaptable to meet changing needs
Lessons Learned AEC • • • Early design commitments Early consideration of MEP and structural systems Cross-disciplinary design contribution Synchronous communication Common Auto. CAD drawing
