A Modern Makeover – A Failed, Tired Masonry Façade Gets a New High-Performance Look

Monday, November 9, 12:00 PM – 1:15 PM EST

This presentation will provide a case study of a medical research/office facility that, at nearly 35 years old, needed major exterior repairs. This mid-1980s building was constructed with thought given to energy conservation and durability by using continuous thermal insulation in the wall assembly and a durable masonry cladding system. Unfortunately, defects in the original design and construction created an exterior wall assembly that developed cracks in the exterior masonry and deterioration of the supporting steel members, and the building lacked an air barrier and leaked air badly, defeating the original energy conservation considerations. The lack of vertical masonry control joints led to widespread cracking and corrosion of supporting steel relief angles. The assessment of the masonry defects discovered that the wall assemblies lacked a weather barrier and an air barrier. Large air leaks were discovered during the cladding assessment, creating another challenge in developing restoration concepts.

The assessment resulted in three options. All steps—from the initial assessment of the building through the various design concepts and options—will review the construction challenges for the new lightweight metal panel over-cladding system, designed with a modern appearance to align with the owner’s corporate image and to coordinate with other research facilities.

Precast Concrete Panel Exterior Wall Systems – Detailing Challenges, Best Practices and Lessons Learned

Monday, November 9, 3:00 PM – 4:15 PM EST

Precast concrete exterior wall panel systems are popular in many urban and suburban areas, largely due to efficiency in terms of installation/erection, cost, and simplicity. Lots of options are available to design and construction professionals in terms of panel sizes, layouts, and architectural finishes and features. Options for anchoring and flashing/sealing glazing systems are limited, and problems can result if details are not carefully developed. Other challenges can include reliably sealing panel-to-panel joints, transitioning to adjacent roofing, waterproofing and rainscreen cladding systems, and coordination among trades. This presentation will describe various challenges related to precast concrete exterior wall system design and construction and will include lessons learned and best practices developed from past projects.

A Burning Question: Performance of Spray Foam Insulation on the Interior Face of Metal Back Pans

Tuesday, November 10, 12:00 PM – 1:15 PM EST

Window wall assemblies are a popular exterior wall assembly for high-rise residential apartment buildings. These systems are economical because of efficiencies of factory assembly and rapid installation on site. With the exception of components deemed “minor”—including thermal breaks in the aluminum frames, sealants, etc.—window wall assemblies are considered non-combustible and, therefore, compliant with building code requirements to limit the vertical spread of fire. The thermal performance of window wall systems is relatively weak, limited by thermal bridging through the frames. Thermal performance can be increased with two-component, closed-cell polyurethane foam insulation spray-applied directly to the spandrels. However, the insulation is combustible and too large to be considered a minor component; so, the entire assembly is often considered to be combustible. This presentation describes full-scale fire exposure tests under CAN/ULC-S134, the equivalent to NFPA 285. The outcomes are used to assess if such walls are combustible. The paper will also consider if the test results can be applied to other window wall assemblies and to assess compliance with building codes in the United States, where Canadian window wall systems are often used.

Buildings Move, Buildings Leak: Revisiting the Critical Link Between Engineering Mechanics and Enclosure Performance

Tuesday, November 10, 3:00 PM – 4:15 PM EST

An enclosure that is appropriately responsive to its environmental loading conditions is one of the most fundamental measures of satisfactory performance for the built environment. Some loads are directly experienced by enclosure components and materials themselves, while other loads are experienced because material deformations or deflections influence those components and materials. While the relationship between structural movement and a structure’s usefulness to its intended purpose has been well understood throughout the history of design and construction, that understanding has not always translated well into satisfactory enclosure performance. Drawing on experiences in post-construction forensic investigations, troubleshooting during construction, and efforts to influence design detailing, this presentation will discuss key factors in applying engineering mechanics for the benefit (or detriment) of enclosure performance. Specific aspects to be shared will include the cross-party dynamics in design and construction that give rise to current challenges, case studies of failures as a result of insufficient consideration, and areas for improvement across the design and construction industry.

Resilient and Adaptable Roof System Design

Thursday, November 12, 12:00 PM – 1:15 PM EST

Weather events are trending to be more destructive. Sustainability focuses on roofing products’ effects on the future; resilience focuses on roofing assemblies’ ability to endure. But how do we adapt roof system designs for an unpredictable climate and energy future in the US and globally?

Long-term building performance necessitates an inherent and essential capacity to design for resilience in the face of vulnerability, and buildings that can adapt to the changing environments in which they were built. What do resilient and adaptive buildings look like, how do they behave, and how do we design for this belt-and-suspenders approach that requires such elasticity? And what role does roof selection and design play?

Learning Objectives:

  • Understand current trends and identify best practice approaches
  • Incorporate concepts into roof system design for 22nd century performance
  • Discuss design considerations including wind uplift resistance, water management, and rooftop energy generation and storage
  • Review resilient design resources

How Much Testing is Required?

Thursday, November 12, 3:00 PM – 4:15 PM EST

Building enclosure commissioning (BECx) is more frequently being required for new construction, and as BECx becomes more common, the gray areas and requirements of BECx are being more heavily scrutinized and questioned. One of the more frequent questions with respect to the building enclosure is related to performance testing; more specifically, how much water testing is required for a new building? While testing procedures and criteria are thoroughly developed and can be readily understood, there currently is no industry-wide agreement or consensus for the extent or quantity of field water performance testing. This presentation will attempt to address the field-testing quantity question through an analysis of existing, yet vague, industry guidelines. Typical buildings and assumptions will be used to show example calculations for determining a sample testing size—specifically for ASTM E1105 testing. The calculated sample testing size will be compared against typical testing requirements, and conclusions will be presented that summarize the results and other factors that should be accounted for when determining field testing quantities.

Nightmares on the Edge: Lawsuits about Concrete Slab Tolerance and Deflection Related to Windows and Curtainwalls

Monday, November 16, 12:00 PM – 1:15 PM EST

The author has been involved as an expert witness in multiple litigations where confusion, poor language, and competing demands have led to million-dollar lawsuits. The negative domino effect starts with specification language, may be affected by value engineering, continues through contract language, develops further in shop drawings, and culminates in a train wreck in the field. The train wreck later falls off a cliff when the slabs deflect over the long term in unanticipated ways. Often multiple parties share blame, including owners, architects, structural engineers, general contractors, façade manufacturers, and façade contractors. Presenting such a complex case to a judge or jury is challenging. After all, if the construction professionals can’t figure it out, how can non-construction judges and juries get it right? In this presentation, the author will focus on what went wrong in the construction process, and will offer solutions that can bring about positive shared expectations of all parties and ultimate project success.

Achieving Building Enclosure Continuity Across Building Movement Joints

Monday, November 16, 3:00 PM – 4:15 PM EST

Structural engineers consider movement joints as a separator or physical break between adjacent buildings (or portions of buildings), while building enclosure designers require movement joints to connect the thermal, moisture, air, and water control layers. Often architectural drawings include a premanufactured movement joint sized to accommodate the anticipated structural movement of the joint. A common challenge is understanding how the movement joint system, which often includes complex geometry, interfaces with the adjacent building enclosure systems that are being connected. The speakers will address how to detail, develop, and construct movement joint systems to maintain enclosure continuity and prevent leakage. The presented approach is based on the speakers’ combined experience investigating failed movement joints, and applying lessons learned to the design and construction of movement joints in new design projects. In this presentation, the speakers will review how movement joints fail from a building enclosure perspective and identify key details and requirements for movement joint systems that are required to maintain a continuous envelope across multiple enclosure systems.

Restoring a Frank Lloyd Wright Residence

Tuesday, November 17, 12:00 PM – 1:15 PM EST

In the 1950s, American architect Frank Lloyd Wright developed a building system using concrete block components that could be assembled into a home, which he described as “Usonian Automatic.” In 1955, Wright designed such a home for Dr. Toufic Kalil and his wife, who built their home in Manchester, NH, with the assistance of a local contractor.

Wiss, Janney, Elstner Associates, Inc. (WJE) was selected by the heirs of the Toufic Kalil House to assess the existing conditions in preparation for selling the home. After WJE’s initial meeting, a landscape contractor demolished a site wall with his truck.

Based on our observations of existing conditions and research of historic documents, WJE developed repair documents to replicate the severely damaged site wall. The company also developed roofing repair and replacement documents to replace the leaking roofing system installed in 2003. Documents from the Frank Lloyd Wright Archives housed at the Avery Library of Columbia University supplemented the Kalil family’s personal papers.

The personal family records revealed names of products used for the original roofing system which differed from those in the project specifications. Little information was found about these products. The challenges of the existing conditions of the concrete roof deck and low flashing heights demanded creative approaches to the roofing replacement material and assembly.

Achievements, Opportunities, and Challenges in Using AI for an Improved Building Enclosure Assessment Practice

Tuesday, November 17, 3:00 PM – 4:15 PM EST

Visual assessment of building enclosures can be repetitive and time-consuming. The industry has also faced numerous challenges in recent years due to shortages in skilled labor, inefficiencies in process, and an increasing focus on worker safety. AI on drone-captured imagery is emerging as an answer for these problems. Although this seems like a straightforward process (capture drone imagery, train machine-learning models, and predict objects and deficiencies), we have discovered, through extensive research and onsite tests, this generic approach often fails to provide reliable outcome in a practical setting. This presentation explores in detail several factors which significantly affect the results—including distance and angle of drone camera to each surface, practicality of a capture plan in terms of time, accessibility, obstacle avoidance, differences in surface materials, large number of assets and deficiencies, and necessity for large training datasets—especially for less-common inventory and conditions. Case studies will be presented showing significant achievements in automation and efficiency when these challenges are overcome. For example, a drone-based data capture of a large hospital facility, coupled with a novel 3-D AI solution, led to more than 84% savings in worker hours compared to the manual assessment scenario.

Using Proper Field Testing for Waterproof Coatings

Thursday, November 19, 12:00 PM – 1:15 PM EST

This discussion focuses on using common industry testing practices to identify potential detrimental conditions related to the installation of waterproof coatings on concrete and masonry surfaces. While showing techniques associated with assessment tools and protocols, the presentation will cover a range of topics related to the installation of various waterproofing materials. Topics will range from evaluating concrete and masonry surfaces prior to coating applications to proper adhesion/bond testing of a range of waterproofing materials. Case studies will be used to illustrate the importance of these tests in preventing issues on projects. While the presentation is product-generic, multiple industry standards, protocols, and accepted practices will be discussed and applied.

The discussion will be broken into two parts. It will begin with substrate evaluation and will show the use of the ICRI 310.2R guideline in evaluating surface preparation methods, exploring the use of various moisture tests available and the conducting of Rilem tube and pH testing. The second half of the discussion will cover material installation. Adhesion testing will be discussed in accordance with ASTM standards for coatings, repair materials, and sealants. Finally, the presenter will describe various methods to determine thickness of wet and dry coatings. These tests, combined with project mock-ups, can assist in avoiding costly issues on projects.

Three Failures and a Save

Thursday, November 19, 3:00 PM – 4:15 PM EST

This presentation will review three building enclosure assemblies that met the building code yet failed in operation. The reasons for the failures will be explained, and live hygrothermal analyses will be run to show the causes of the failures. One of the projects in design development had an exterior wall assembly that met the building code yet was destined to fail. A live hygrothermal analysis will be run to show why the failure would have occurred. Changes were made to the exterior wall design so that it would not fail. These will be reviewed and a live hygrothermal analysis will be run to prove that it will not fail.
