Better Building Performance – Constructability through Collaboration
Often in the construction industry, design conditions exist that stretch and sometimes exceed the bounds of achievement. Although macro items tend to be more easily identified and well vetted in design, it’s the micro elements that consistently plague the construction process and potentially wreak havoc for the project delivery team. It is the responsibility of the team to expeditiously identify these pinch-points and problem-solve to avoid performance detriments that may include water leakage, air infiltration/exfiltration, and/or thermal losses while minimizing impact to schedule and budget.
The quality of the solutions presented, and the manner in which they are executed is rooted in collaboration that is sourced by the diverse backgrounds of experience of the project team members, which can include the designer, enclosure consultant, specialty contractor, manufacturing representative, general contractor, and building owner. Each members perspective is valuable, but effective communication and buy-in from the project team is paramount to realize success.
The 2019 RCI Region V Meeting presents case studies of issues in the building enclosure/envelope community encountered during design, construction, investigation, manufacturing, code development, and/or testing that address constructability through collaboration and result in effective building enclosure systems and performance.

Building Enclosure Pareto Principle: Optimizing Efforts via Collaboration
8:15 AM – 9:30 AM
The in-situ performance of building enclosures can remain inferior to intended criteria due to inadequate detailing and incomplete specifications during the design phase, variation of installation methods and imperfect jobsite conditions, insufficient communication and collaboration between project team members, and unrealistic construction scheduling, among other issues. Although project documents often clearly define performance requirements for individual building enclosure components, considerations of interface details often remain underdeveloped. These interface details often cannot be fully designed until subcontractors are selected, manufacturers and products are evaluated, and shop drawings are prepared. Coordination is typically left to the general contractor with respect to sequencing issues, means and methods, material compatibility concerns, etc. The continued and accelerating use of delegated design make timing of coordination tasks more difficult. Ample opportunities exist to improve construction processes and validation procedures by effectively coordinating and collaborating throughout the construction project life cycle.
- Learn best practices to specify quality assurance and quality control measures, including challenges associated with building enclosure system integration.
- Review examples of collaborative opportunities throughout a construction project life cycle.
- Learn the various responsibilities of parties involved in projects with delegated design provisions.
- Develop understanding building enclosure commissioning and means to ensure greater value than that of a box-checking exercise.

Interface – Understanding the Impact of Transitions on Façade Performance
9:30 AM – 10:45 AM
While typical conditions of exterior enclosure systems are generally well marketed, documented, tested, and assembled, atypical conditions, inherent to every project, are often overlooked, underdeveloped, and the cause of weaknesses in performance.
This presentation will explore the challenges on air-and water-tightness, thermal continuity, constructability, and accountability caused by changes in geometry, materials, systems, and gaps in scope allocation using completed interface examples.
Using at-grade, in-plane, overhead and parapet transition details as a baseline, the importance of careful interface detailing for high-performance envelopes and the responsibility of the architect in this process will be discussed.
- Discover the impact of building façade on overall energy consumption and occupant comfort.
- Learn how to simplify envelope detailing to achieve high performance.
- Determine how and when to use visual, virtual and performance mock-ups.
- Ensure façade performance goals are clearly communicated and executed.

Tying it Together as the GC: Establishing Acceptance Criteria for Design and Installation of Roofing/Waterproofing Systems
11:00 AM – 12:15 PM
Using collaboration tools and processes, DPR Construction and trade partners have established key guidelines for the successful installation of roofing and waterproofing. Setting design acceptance criteria early in preconstruction has helped to identify requirements at design and ultimately at mock-up and installation milestones. Establishing defining features of work with all stakeholders helps the team plan and execute the installation. Using BIM, DPR Construction has defined critical areas of coordination, including roofing and flashing, rooftop equipment, and equipment pads. This presentation will give case studies and outline guidelines and technologies DPR uses for successful install of roofing and waterproofing systems.

Deceptive Code Amendment Defeated
1:15 PM – 2:30 PM
There’s a good chance many IIBEC members have experience with code hearings where they have left frustrated. So has Mr. Schaber. Recently, a diverse group of concerned organizations in Oregon rose to defeat a proposed code amendment that would have only benefited a few roofing manufacturers. It’s amazing how much you learn when you go on a quest for facts about the issue at hand.
In this case, a group of manufacturers, working through the Global Cool Cities Alliance, applied to the State of Oregon Building Codes Agency to make cool roofs mandatory on air-conditioned buildings in Western Oregon. This group of manufacturers sponsored an alliance to promote the growth of cool roof sales under the guise of energy and environmental benefits that would result in roofs that would pay for themselves. Unfortunately for them, the out-of-town alliance didn’t make it out to Oregon to do any research to back up their claims.
What worked in opposition of this proposed amendment was the diversity and breadth of the participants. There were taxpayers (thanks to encouragement from BOMA); a spokesman from The Oregon Confederation of School Administrators, (OCSA), who spoke on behalf of school associations for business managers, facilities managers and school board members; National, Western, and Portland Roofers Associations; two multiproduct roofing manufacturers; and the Portland Chapter of the IIBEC all assembled to fight the change. After this team was organized, they were fine-tuned by Ellen Thorp of the ERA and Mike Fischer of ARMA. The coalition fought poorly implemented computer simulations with in-field experience and speculation with facts. The result was multiple advocate groups working for the benefit of all – an exciting concept and a model for future situations that can empower the roofing industry as a whole.
- How to successfully fight a code change.
- How to build a coalition.
- Understanding the code change process.
- The value of real-world experience as a tool for empowerment.

Parapet Predicaments and Roof Edge Conundrums
2:30 PM – 3:45 PM
The roof meets the wall at the intersection of design aesthetics, functionality, durability, construction sequencing, and maintenance. Each of these perspectives have champions- often with competing interests, that can significantly influence the success of this critical interface. Proper alignment, detailing, coordination and execution are paramount. Continuity of moisture, air, vapor and thermal layers are necessary for long-term performance and require project-specific detailing.
There will be a review of a variety of building types, discussing the continuity of detailing required to manage moisture, air, vapor and thermal performance, as well as wind resistance requirements at the critical wall-to-roof interface. Code requirements and how to achieve compliance through design will be discussed. This session will provide guidelines to successfully navigate these often competing interests and provide strategies for achievable performance through design and specification without compromising the aesthetics with distracting details over the edge of the roof. Detail examples that gracefully and not-so-gracefully blend together to form and function at various roof-to-wall interfaces, will be reviewed, identify variations to account for constructability, various trades, and construction phase sequencing. Lastly, methods will be provided to integrate the project team throughout the process to elevate the probability of success and minimize construction phase changes.
- Understand requirements to manage moisture, air, vapor and thermal continuity.
- Understand code requirements and how to achieve compliance.
- Outline design and specification requirements to set achievable performance.
- Develop critical details blending form and function.
