27 Design Assist Prior to completion of design, a contract may be awarded to specialty contractors to engage with the Design Team in completing the engineering and design work Specialty contractors act in a design capacity, but under contract with the General Contractor or direct with the Owner 30

34 Why the Emergence of Design Assist? Increasing performance requirements Energy / Thermal Acoustics Material advancements New materials Big larger glass San Francisco Museum of Modern Art 37

36 Emergence of Design Assist Increasing complexity in form along with new materials and scale of applications were making it increasingly difficult to rely on historical data for cost estimating To get to true costs, subcontractors and material suppliers had to be engaged more directly San Francisco Museum of Modern Art Photo Henrik Kam / SFMOMA 39

45 Commercial Trends All-glass aesthetic Large glass lites Floor-to-ceiling glass Increasing performance requirements: Energy / Thermal Acoustics Iconic Geometries Multiple wall-types Unusual configurations Decrease in repetition 10 Hudson (Tower C) I New York, NY Photo Enclos Corp. 48

46 Reality of Design Assist in Action Duration varies greatly Contract terms Trust between GC or Owner and subcontractor Cultural and institutional projects have endured the risk behind many innovations, both material and procedural Chase Center Arena and Office Towers San Francisco, CA Courtesy of Golden State Warriors, Chase & Manica Architecture 49

47 When Does Design Assist Make Sense in Commercial Projects? Desire to introduce constraints early in the design process Striving for an unusual geometry, material application, or overall complexity an iconic building High complexity, yet, traditional schedule expectations IF YES TO ALL OF THE ABOVE, THEN DESIGN ASSIST MAY HELP MITIGATE RISK. 10 Hudson (Tower C) I New York, NY Photo Enclos Corp. 50
