  2. OVERVIEW • Client and Organization • Project Description • Design Requirements • Project Approach • Design Solution • Conclusion

  3. CLIENT AND ORGANIZATION • Hunt Construction Group - Indianapolis, Indiana - Robert W. Fuller, Construction Manager

  4. PROJECT DESCRIPTION • Yale University in New Haven, Connecticut New Haven

  5. PROJECT DESCRIPTION • Parallel bid process • Identify missed details • Discover alternative approaches • Obtain an understanding of construction methods and procedures

  6. CONSTRUCTION MANAGEMENT • First year a Construction Management Project offered at Rose-Hulman • Learning along the way with our professors • Difficulties fitting design criteria into our project

  7. DESIGN REQUIREMENTS • Constraints - No historical buildings or landmarks may be harmed These areas include: KNOT GARDEN HISTORIC MANSIONS SITE LUCE HALL

  8. DESIGN REQUIREMENTS • Deliverables - Project Proposal - Site Utility Relocation Bid Package - Excavation Support/Shoring Design - Excavation Bid Package - Wall Formwork Selection - Wall Formwork Bid Package

  9. PROJECT APPROACH • Design/Assessment of Options - Utility Relocation - Current utilities run directly through proposed site - Utilities relocated and functioning before excavation begins

  10. PROJECT APPROACH • Sheeting and Shoring - Geotechnical report obtained from Hunt - Considered numerous shoring options Typical Soldier Pile/Lagging System

  11. PROJECT APPROACH • Select Wall Formwork System - Foundation design provided by Hunt Construction - GPHB will select appropriate formwork system - Numerous options in consideration - Criteria of Selection: constructability, cost efficiency, functionality

  12. PROJECT APPROACH • Utility Relocation Bid/Excavation & Formwork Bid - Guaranteed Maximum Price (GMP) bids - 2006 RS Means Manual - Labor Rate Adjustments - Unit Material Prices - Bonding, Permits, Fees

  13. PROJECT APPROACH • Codes & Regulations - Occupational Safety and Health Administration (OSHA) - Connecticut State Building Code - International Building Code (IBC) - Environmental Protection Agency (EPA) - Leadership in Energy and Environmental Design (LEED) - LEED Silver Certification (possibly Gold)

  14. UTILITY RELOCATION • Assessed multiple routes for utility relocation • Conducted research for two different excavation methods - Open Trenching - Directional Boring RECOMMENDATION:OPEN TRENCHING because directional boring poses many problems with such a high volume of utilities running beneath Prospect Street.
