  2. Highland Elementary School • New 78,880 SF facility • Ambridge, PA (American Bridge Company) • Foreman Architects Engineers • $14.7 million project cost • Constructed April 2003 - August 2004 • Minimal change orders & few claims Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  3. Thesis Studies • Two issues facing public school districts:Delivery Methods & Daylighting • Three studies: • Construction Management Depth:Project Delivery Methods in Public Schools of PA • Lighting/Electrical Breadth:Facade Redesign & Daylighting • Mechanical Breadth:Impact of Façade Redesign Highland E.S.

  5. Separation of Contracts • Multiple prime requirement – 5 U.S. states Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts • PA Education Empowerment Act, passed in 2000 • 32 waivers granted for PA public school construction projects (with project costs greater than $3 million) • = 16% of all waivers granted • Waivers specifically for single prime delivery • Not 32 single prime school projects in PA

  6. Project Delivery Methodsin Public Schools of PA • Goal • Is single prime most effective delivery method forPA public school projects? • Is the mandate waiver system useful in PA for the separation of contracts requirement? • Methodology • Research single prime projects and the mandatewaiver program. • Survey personnel at school districts with experiencein single prime projects. Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  7. Why a Survey? • “The waiver will allow the school to…operate in a more effective, efficient or economical manner.” • Waiver applications—support single prime position with opinions of industry players. • Claim benefit to school district in 5 areas:Schedule, Quality, Budget, Safety, and Litigation • Surveyed personnel at school districts with waivers Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  8. Area Believed Project Benefitedfrom Single Contract Believed Project Did Not Benefit from Single Contract Unsure If Project Benefited from Single Contract Budget 5 1 1 Schedule 3 1 3 Quality 6 0 1 Safety 6 1 0 Litigation 6 0 1 School District Survey Results How did a single prime contract impact these five areas? Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  9. School District Survey Results • Benefit in 4 of 5 areas • Logic suspect: Unsure benefit to project schedule  Benefit to budget? • Response from 33% of school districts • 2003-2004 Study at Univ. of Pittsburgh • Single prime = less frequent litigation • Multiple prime w/ CM agent = most SF/day • Different delivery methods suitable fordifferent owners is desirable Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  10. Conclusions • Is single prime most effective delivery method forPA public school projects? • Cannot confirm that it is “most effective” • Benefits have been seen in some cases Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts • Is the mandate waiver system useful in PA for the separation of contracts requirement? • Allows delivery method most suitable to owner • Little guidance given to school districts, should come from an organization representing their interests

  11. Front Façade & Entrance • Goal: Create alternative classroom wing façade design to increase daylight levels, reducing energy demand. Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  12. CAD Model of As-Built Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  13. CAD Model of Alternative Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts 1st & 2nd Floor window area increased by 88%3rd Floor window area increased by 142%

  14. Daylight Study • Daylight Study for as-built and alternative design • AGI32 parameters • 10AM & 2PM on 15th of April, August, December • Overcast, party cloudy, clear conditions • Reflectances of materials as installed • Electric lighting in different on/off configurations • Pendant mounted lighting fixtures as installed, direct/indirect, (3) 32W fluorescent lamps Highland E.S.

  19. Effects on Mechanical System • Unit VentilatorSystem inClassroom Wing • 3 Steps tosizing a UV: • OA • Loads (HAP) • Circulation • Critical—cooling load in south classrooms • UV selection based on cfm delivered to space Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  20. Effects on Mechanical System • UV model specified throughout classrooms meet requirements of alternative design • OA requirement unchanged • Cooling coils capable of new load of 25,838 BTU/hr • 350-450 cfm per ton of cooling load • Effects on mechanical system do not prevent success of proposed façade redesign. Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  21. Final Thoughts • Dispelled personal misconceptions • Met goals & made conclusions • Utilization of single & multiple prime delivery should continue for PA public school projects • Mandate waiver program is useful, but more guidance should be available to school districts • Façade redesign is not a good recommendation, mainly because of impact to architecture Highland E.S. Thesis Studies ConstructionManagementDepth Lighting/ElectricalBreadth MechanicalBreadth Final Thoughts

  24. Opportunity Missed? • Mt. Lebanon School District, Pittsburgh • Waiver approved 11/21/02 for renovation work on seven schools in district • With single prime, estimated savings to be 5% of construction costs • $40 million  $1.5 to $2.5 million savings • Litigation against other school districts utilizing waivers • Chose not to use multiple prime waiver
