  • Project Overview
  • Research: Building Respect
          • Project Redesign
  • Breadth # 1: Precast Panel Alternatives
  • Breadth # 2: Implementing UVGI systems
  • Conclusions
slide6
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
slide7
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
slide8
Building Respect – Close Proximity Sites
      • The current relationships of;
        • Team members
        • Between parties
      • Past project success and failures
      • Applying industry experience to this project
slide9
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
slide10
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
slide11
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

Presentation Agenda
  • Project Overview
  • Research: Building Respect
          • Project Redesign
  • Breadth # 1: Precast Panel Alternatives
  • Breadth # 2: Implementing UVGI systems
  • Conclusions & Recommendations
  • Acknowledgements
slide13
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
slide14
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
slide15
Breadth # 1 - Precast Panel Alternatives

EIFS Quality Issues

- Water Entry

- Impact Damage

- Maintenance

slide16
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
slide17
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
slide19
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

slide21
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
slide22
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
slide23
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
slide24
Breadth # 2 - Utilizing UVGI Systems

Technical Considerations

slide25
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
