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

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

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

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

Project Redesign - Acceleration Existing Situation Existing Situation Designers only redesignDesigners only redesign No involvement from BuchNo involvement from Buch Lack of communicationLack of communication Desired Situation Desired Situation Assistance from BuchAssistance from Buch Meetings and increased communication to Buch from Federated and DesignersMeetings and increased communication to Buch from Federated and Designers Buch Involvement Benefits Buch Involvement Benefits Decreased scheduling timeDecreased scheduling time Cost savingsCost savings

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

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

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

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

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

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

Breadth # 1 - Precast Panel Alternatives Heating Power Required Cooling Power Required Energy Saved Precast Panels 770 kWh60 kWhN/A 2” EIFS621 kWh47 kWh162 kWh 4” EIFS532 kWh40 kWh258 kWh

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

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

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

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

Breadth # 2 - Utilizing UVGI Systems Technical Considerations

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
