Once installation is scheduled, the panels can be delivered to the site in the sequence of installation and erected in one continuous operation. Rolling the dice on prefab exterior, bathrooms Another example is the newly opened 214-bed Henderson Hospital in Nevada. The project team was challenged to deliver in record time, at a price far below any comparable benchmarks. A combination of off site prefabricated patient bathrooms and onsite prefab- ricated and assembled exterior panelized skin, adapted from the casino tower industry, was instrumental in achiev- ing high quality at low cost, with a 27-month construction schedule. The hospital was the fi rst and perhaps most critical piece of the new Union Village — an integrated medical community development. As such, it was held to both the local planning department standards, as well as the conditions established by the community. These included building design characteristics, materials and application, as well as glazing and opening proportions. In addition, local climate and energy require- ments played a signifi cant role in the building skin design. A focused team, includ- ing designers, constructors, estimators, skin specialists, structural engineers and owner's representatives as- sessed several factors. First considered were types of mate- rials. More than 13 diff erent skin types and wall assemblies were reviewed. They ranged from concrete panels, block walls, curtainwalls, exterior insulation and fi nish system, metal panels and stucco just to name a few. Factors used to evaluate these included square-foot cost, install speed, structural impact, city and local design standards, fl exibility in design, modularity, warranty, durabil- ity, skill of local labor force and LEED and energy perfor- mance. At this point, certain wall types began to yield more advantages, yet no single wall type stood out as a paramount option. Concurrent to the material investigations, the team was receiving preliminary plan- ning layouts of the building. To maintain an aggressive sched- ule, the decisions on the exteri- or construction had to be made well ahead of the completion of the planning and develop- ment of fi nal elevations. The team also relied on conceptual estimates for percentages of glazing and set targets based on a value established by both the city's criteria and bench- marked hospitals. An 18 per- cent glazing target was set and assumptions made based on early planning as to how that would be distributed. This also helped to inform early energy analysis models prior to the completion of the design. Final material selection considerations The location, amount and distribution of glazing were not directly tied to the exterior material selection. However, it did play a signifi cant role in the methods of assembly. For example, larger spans of glaz- ing fared better with curtain- wall systems where smaller punched windows served panelized options best. As it stands, in the fi nal con- dition there was approximate- ly 23,764 square feet of glazing, 35,797 square feet of low-rise skin and 65,739 square feet of skin at fl oors two through SKIN continued page 23 >> 1.800.428.4065 TOLL FREE www.willoughby-ind.com V Behavioral Healthcare Lavatory Healthcare Fixtures That Last! © 2016 Willoughby Industries Inc. e Fixtures That Last!
