4. Project Overview Location: Chevy Chase, MD Construction Managers – Buch Construction – Above grade Building Size: 3 story w/ Penthouse - 180,000 sq. ft. Construction Schedule: November 2005 - August 2007 Delivery Method: Design-Bid-Build Function: Retail Department Store Cost: $18.86 Million

5. Presentation Agenda • Project Overview • Research: Building Respect • Project Redesign • Breadth # 1: Precast Panel Alternatives • Breadth # 2: Implementing UVGI systems • Conclusions

6. Research Background • Many projects have either neighboring projects, or share a site with another Construction Management firm • Bloomingdales has multiple contractors sharing the site • Utilization of the CM during redesign phases • Mid-construction redesign was completed without the aid of Buch • Survey Utilization • Satisfaction or displeasure within project team interaction • Experience of Construction Industry professionals

7. Building Respect – Close Proximity Sites • Objective • Identify common inefficiencies • Lack of forward communication • Mutual respect between projects teams • Identify the current relationships • Establish method of practice for the ideal relationship

8. Building Respect – Close Proximity Sites • The current relationships of; • Team members • Between parties • Past project success and failures • Applying industry experience to this project

9. Project Redesign - Acceleration • Objective • Identify common inefficiencies and lack of communication between projects teams, owner and CM during the Redesign process • Ideal interaction between all parties • Redesign; cost, time, project quality, and efficiency can be VE

10. Project Redesign - Acceleration • Existing Situation • Designers only redesign • No involvement from Buch • Lack of communication • Desired Situation • Assistance from Buch • Meetings and increased communication to Buch from Federated and Designers • Buch Involvement Benefits • Decreased scheduling time • Cost savings

11. Conclusions & Recommendations: Partnering – method to improve quality, and reduce confrontations between parties, thereby allowing open and non-adversarial contracting environment Working toward common goals in a trusting environment with open communication is critical during VE and Redesign Federated must require monthly/weekly meetings to address issues and create an atmosphere for forward communication, more so than what was done An establishment of relationships between the home offices of both general contractors will aid greatly in coordination

13. Breadth # 1 - Precast Panel Alternatives • Objectives • Analyze energy efficient alternatives for the construction of the facade • Choose the most economical material for use on the building façade • Considerations • Calculate energy efficiency between the systems • analyzed • Resulting structural load • Practicality of alternate system

14. Breadth # 1 - Precast Panel Alternatives • Exterior Insulating Finishing Systems • 3 layers • - Insulation board • - Base coat (wire mesh and adhesive) • - Plaster finish coat • Variety of textures, colors, finishes • Light weight cladding

15. Breadth # 1 - Precast Panel Alternatives EIFS Quality Issues - Water Entry - Impact Damage - Maintenance

16. Breadth # 1 - Precast Panel Alternatives • Minimizing Water Entry • Architectural & contractor design input • Quality sealant contractors • Quality inspectors • Immediate crack repair • Overlap reinforcement at corners, • openings • Moisture draining EIFS

17. Breadth # 1 - Precast Panel Alternatives • Minimizing Impact Damage • Heavy mesh usage in high impact areas • Base coat with higher resin levels • Limiting material to possibility of impact • Maintenance • Use mild detergent for cleaning • Acrylic finishes reduce dirt pick up, help maintain system colorfastness

18. Breadth # 1 - Precast Panel Alternatives

19. Conclusions & Recommendations: Incorporating a 4” EIFS is recommended to increase the energy efficiency and reduce structural loading and material cost Today very few commercial systems fail when a quality control system is in place, and an experienced contractor is handling the construction. Aesthetically EIFS does not vary greatly from the panel system and may be easily approved by the architect and owner, as the system specification can be easily varied

21. Breadth # 2 - Utilizing UVGI Systems • Objectives • Analyze the added energy efficiency and building quality that UVGI provides • Considerations • Indoor air quality improvements • Reduction of causes for ‘Sick Building Syndrome’ • Practicality adding UVGI systems

22. Breadth # 2 - Utilizing UVGI Systems • Sick Building Syndrome • Headaches, asthma, allergy like symptoms • Cost estimates range to billions due to absenteeism, loss of productivity • Damp air ducts, outdoor air, adhesives, airborne particles

23. Breadth # 2 - Utilizing UVGI Systems • Ultraviolet Germicidal Irradiation • High exposure to concentrated UV rays • Eliminates Bird Flu, TB, Influenza, Anthrax, etc • Reduces the causes for ‘Sick Building Syndrome’ • Cause less sick leave • Increases productivity

24. Breadth # 2 - Utilizing UVGI Systems Technical Considerations

25. Conclusions & Recommendations: Though the implementation of UVGI yields a substantial initial investment it will pay for itself in reduced absenteeism, increased productivity, and indoor environment quality 30% to 40% energy savings from cooling coils operating efficiently to their original specs, due to no biofilm growth

27. Conclusions & Recommendations: Implement partnering to improve quality, and reduce confrontations between parties, thereby allowing open and non-adversarial contracting environment Working toward common goals in a trusting environment with open communication is critical during VE and Redesign Incorporating a 4” EIFS is recommended to increase the energy efficiency and reduce structural loading and material cost Implementing UVGI systems to reduced absenteeism, increased productivity, and indoor environment quality
