Project Overview CM Analysis 1 CM Analysis 2 Structural Redesign Mechanical Analysis Research Topic Conclusions Questions Derek Snover Construction Management

Project Overview CM Analysis 1 Problem CM Analysis 2 Generation gap between older generations and today’s Structural generation in understanding the benefits and Redesign Mechanical effectiveness of Green Building Design. Analysis Solution Research Topic � Hold seminars Conclusions � Push harder to convince owners Questions � Make Green Building Design a priority � Green Building products cheaper, more mainstream Derek Snover Construction Management

Project Overview CM Analysis 1 Interesting Note: CM Analysis 2 “I am not sure what gap exists. People often say there is a generation gap, but what does this mean? I think one could do a thesis paper on Structural this topic alone: The Generation Gap: Fact or Fiction? Redesign Mechanical I think my generation (Baby Boomers) started programs focused on Analysis saving the planet back in the late 60’s and early 70’s. Research Topic Green Design is not new. What is new is that it has become very Conclusions organized. Back in the 1970’s during the first oil crisis, everyone was looking into ways to create passively energy saving devices for Questions buildings, including solar air conditioning.” - Gary Smith PBS&J Derek Snover Construction Management

Project Overview LEED Rating CM Analysis 1 � Possible to achieve GOLD status, 41 points CM Analysis 2 ICRA Plan Structural � Class IV plan required Redesign • Plan to use solid wall barriers with HEPA filtered clean room Mechanical • HEPA vacuum cleaners and sticky mats at all entrances Analysis • Optimal phasing to provide cleanest environment Research Structural Redesign Topic � Reduced schedule time (18 days) and labor costs ($11,199) Conclusions � Reduced structural steel member amount Questions Mechanical Analysis � Harvest 1,128,597.31 gallons/year � Eliminated 100% grey water demand � 16 tanks required to contain harvested water Derek Snover Construction Management
