3 YOU ARE HERE New health care facilities are required to meet the needs of aging Baby Boomers and a growing Millennial workforce. Construction of these facilities can pose logistical challenges in tight urban environments for projects like the new Hale Family Clinical Building at Boston Children s Hospital in the Longwood Medical Area. The 550,000 square foot, eleven story building will add 3 acres of surgical space, a state of the art neonatal intensive care unit, and improved patient amenities in the heart of the growing hospital campus. HALE SITE In this session, we will discuss the need for new health care and life science facilities and show how site constraints, phasing requirements, schedule demands, and technical infrastructure upgrades led to designing a completely prefabricated facade for the Hale building. Members of the design and construction team will also review the design assist process and touch on other project requirements, such as interior microclimates and facade reuse. 5 LEARNING OBJECTIVES Discuss how changing consumer demands are transforming health care facilities. Identify site, schedule, and quality constraints that led to using prefabricated wall panels at the Hale Family Clinical Building. Understand key performance features of prefabricated wall systems for medical and life science facilities. Learn how to overcome common limitations of panelized building enclosure systems with collaborative design, 3D modelling, and hygrothermal analysis. 6 Simpson Gumpertz & Heger

15 Fabrication facilities can operate in inclement weather and workers are more productive in a controlled environment. Schedule and Productivity Fabrication and assembly can begin in advance of steel erection. Erection on site is faster and building is enclosed quicker to allow weather sensitive trades to begin work sooner. More working room is available on site with just in time deliveries. Minimizes on site waste and surplus materials increasing the amount of workable area on the project site Simpson Gumpertz & Heger

16 Labor Costs Fabrication facility workers typically have lower wages than skilled on site workers. Skilled worker with higher wages are only used for critical procedures such as installation. Fabricator required to employ a additional engineering and management staff increasing costs. Additional design costs for each component for fabrication. 31 Material & Equipment Costs Buy in bulk, which reduces material handling costs from manufacturers such as milling and cutting. Deliveries can be maximized to the fabrication facilities reducing shipping fees from manufacturers. Purchasing equipment for fabrication in lieu of paying high rental costs for each project. Increased costs for maintaining equipment. 32 Simpson Gumpertz & Heger

17 Wall Subcontractor Selection Request for Proposals Instructions: Provide a panelized wall system for the exterior of the building to include the following: Glass and Aluminum Curtain Wall Systems Storefront and Vestibule Aluminum framed entrances including hardware Precast Stone Panels Louver panels with stud back up system (Priced as an alternate) Metal Panels and support system Exterior Canopies Soffits Exterior Metal Stud System (Including horizontal surfaces, i.e. soffits) Exterior Sheathing A V Barriers and transitions strips as required. Insulation Sheet Metal Flashings and Trim Joint Sealants / Caulking systems Interview Process Allows the bidders an opportunity to present their proposed design intent and strategy to the Owner, Design team and Suffolk for consideration. Explain their Design Assist Process. 33 SESSION TWO: PANELIZE+ PERFORM Prefabricating a New Clinical Building at Boston Children s Hospital JIM CHAMBERS Shepley Bulfinch JASON LANSBERRY Suffolk Construction JOSHUA KIVELA Simpson Gumpertz & Heger Simpson Gumpertz & Heger

18 Design Assist Process What is design assist and why do we use it? Collaboration between wall contractor and members of the design and construction team to achieve design intent at budget and on schedule Develop shop drawings during process Adjust project specifications as required to align with design Long lead time of glazing Design efficiency Fewer change orders Cost control 35 Design Assist Process What made our process successful? Defined process Defined deliverables Schedule alignment 3D modelling Shorter schedule duration compared to design bid build 36 Simpson Gumpertz & Heger
