On 3.20 at #RCICTS2017 , Jeff Bowlsby, of +Simpson Gumpertz & Heger , and Lee Cope of +Wiss Janney Elstner Associates Inc will present "Designer Choices and Responsibilities in ASTM C1063 and ASTM C926 Regarding Portland Cement Plaster Wall Claddings" The speakers will discuss designers’ responsibilities for the effective design of Portland cement plaster (stucco) wall claddings as specified by ASTM stucco industry standards. Standards ASTM C1063 and ASTM C926 were carefully researched by two design professionals who contributed to their development.

On 3.20 at #RCICTS2017 , William Coltzer and Christian Ozbun, of Zero/Six Consulting , present "Optimizing the Building Envelope With a BIM-Based Framework." Imagine putting together a puzzle with pieces designed by ten different companies. The building envelope process is like that puzzle; it is made up of an aggregate of multiple designs coming together for the first time, onsite. Building Information Modeling (BIM) puts all the pieces together virtually so that multiple design elements come together onsite with design mistakes and oversights identified and corrected. In 2015, Zero/Six collaborated with Hensel Phelps to assemble the pieces in a BIM framework to coordinate shop drawings for a 432,671 square feet (sq. ft.) facility. The speakers will discuss how to optimize the building envelope through BIM workflow processes, organizing the model by trade, project sequencing, and generating quantities directly from the data. BIM allows designers to put the building envelope puzzle together before dumping all the pieces out of the box.

On 3.20 at #RCICTS2017 , "Structural Assessment of Glass Restoration" will be presented by Stephen M. Morse of +Texas Tech University and Mark Schmidt, PE, SE of +Wiss Janney Elstner Associates Inc The glass-clad surfaces of building envelopes may be damaged by construction activities, high-wind events, explosions, and façade maintenance or repair activities. In some cases, the affected glass can be restored to an acceptable condition using a combination of wet and dry polishing methods. This polishing treatment removes a thin layer of glass at the blemish locations. Reduction of glass thickness may cause concern for the structural integrity of the glass, particularly with heat-treated glass. Using case studies, the authors will discuss how to assess heat-treated glass restored by polishing.

On 3.20, at #RCICTS2017 , "Laboratory and Field Testing Parameters to Determine Concrete Crack Geometry and Polyurethane Grout Design" with Chadi El Mohtar of +The University of Texas at Austin and Jim Spiegel of +SealBoss Corp. Concrete Solutions . The presenters will highlight research designed to use flow and permeability data to predict crack geometry as applicable to leak-sealing applications. This research is being performed by speaker Dr. Chadi El Mohtar. The laboratory results from pressure and flow testing through varying crack sizes will be examined to ultimately suggest pre-injection exploratory efforts to identify crack geometry and, ultimately, improved methods for polyurethane grout selection. This presentation should prove informative to the specifying community and building owners as a possible new quality assurance standard in chemical grouting.

On 3.19 at the RCI Convention and Trade Show, "A Comparison of Three Energy/Enclosure Retrofit Strategies" will be presented by Martin Houston of Walsh Construction Co. From 2015 through late 2016, Walsh Construction Company executed three different and distinct enclosure energy retrofits. Each retrofit featured different structural systems, water-resistive/air barrier approaches, and thermal control strategies. The projects had the common goal of providing a durable and energy-efficient enclosure. The speakers will examine the decision-making process for each enclosure to demonstrate how decisions were made as related to existing structure and project goals. The presenters will analyze specific assemblies, products and details in terms of design and execution, and deliver objective information about the performance of each. http://rci-online.org/building-envelope-edu/convention-ts/

At the RCI Convention and Trade Show on March 19, 2017: "Slate Roofing for Consultants: What You Need to Know," presented by Jeffrey Levine of Levine & Company, Robert L. Fulmer, of Fulmer Associates, and Douglas C. Fishburn, of Fishburn Building Sciences. In 2015, RCI members were surveyed regarding slate roofing. RCI, in conjunction with the National Slate Association, conducted the poll. The tabulated results showed a strong interest in specific areas of slate roof design and form the basis for the content of this presentation. This program will feature three topic areas. Slate Sources includes information on domestic, international, and reclaimed slate. The Slate Roof Assessment segment focuses on the slate shingles themselves, slating nails, flashings, repair vs. replacement decision-making, and expected remaining service life. Fasteners, underlayments, and flashings will be addressed in the Detailing segment.

RCI Convention and Trade Show Educational Session:"Reflective Roofing Research: The Influence of Roof Color on Adjacent Air and Surface Temperatures" will be presented by Elizabeth J. Grant of the Virginia Tech School of Architecture and Design. Roof system design has important ramifications beyond the performance of the roof itself. To answer questions about the thermal effects of roof color on the building environment, a research project was conducted by the Center for High Performance Environments at Virginia Tech. The program was supported by the RCI Foundation. Black EPDM and white TPO membrane overlay areas were instrumented with temperature sensors and a weather station. The study tested the relationship between roof color and resulting temperatures on roof surfaces, in the air above them, on conduits above them, and at adjacent opaque and glazed façades. Reg. deadline is 2.13!

At the RCI Convention and Trade Show, "In-Situ Measurement of Wind Performance of Roof Edge Systems" will be presented by Appupillai Baskaran of +National Research Council Canada . In commercial roofing, metal edges are the first line of defense against the effects of wind. As part of the Roofing Industry Committee on Weather Issues’ (RICOWI’s) Wind Investigation Program (WIP), North American roofing professionals completed a major fact-finding investigation immediately following the landfall of Hurricanes Charley, Ike, Ivan, and Katrina. Field data clearly supported that the majority of the roof failures were due to the failure of metal roof edges. These findings suggest that current building codes (i.e., NBCC and ASCE) do not accurately specify wind design loads acting on roof edge metal systems. The speaker will present the findings of measured wind-induced pressure acting on all surfaces of three different edge configurations. http://rci-online.org/building-envelope-edu/convention-ts

Sunday, March 19, at RCI Convention and Trade Show will kick off with Kevin D. Ouellette of Evan Fall Protection talking about "Avoiding Unforeseen Liability in the Design and Recommendation of Fall Protection." It is common practice these days for building owners to reach out to designers and roofing consultants for recommendations for fall protection. The need and requirements for fall protection on a building are specifically addressed in various standards and regulations. The responsibility for the identification of a fall protection need commences with the building owner. This presenter will describe the inherent liabilities of a building owner, and how they can unknowingly be passed to consultants. Don't miss it! Register soon to take advantage of early registration pricing! http://rci-online.org/building-envelope-edu/convention-ts/cts-edu/
