The Risks and Realities of Mitigating Ice and Snow Release from Buildings

Tuesday, May 4, 12:00 PM – 1:00 PM ET

The mitigation of design and operational risk associated with the accumulation and release of ice and snow from buildings is an experience-based, complex, and challenging endeavor. Recently there have been reports of increased frequency and severity of problematic ice and snow release from high-performance buildings, which is leading to extended periods of restricted access and lost productivity for building occupants, neighboring buildings, and adjacent public thoroughfares. Consequently, the release of ice and snow from buildings and structures not only poses a hazard to people and property, but also presents an increased risk to designers and owners. To effectively mitigate the issues of the design state, an evaluation of the frequency, severity, and design sensitivity to problematic ice and snow accumulation needs to be investigated by an experienced expert and weighed against the acceptable level of reliance on building operations to manage the risk of an incident occurring.

Retrofit and Adaptive Reuse of the Historic Pavilions of St. Luke

Thursday, May 6, 12:00 PM – 1:00 PM ET

Historical nineteenth- and twentieth-century buildings are currently facing the necessity of meeting contemporary needs such as adaptive reuse, emerging efficiency, stability, and durability. The characteristics of architecture of these periods, i.e., materials, design, details maintenance, and functionality, increasingly make it challenging to maintain authenticity while incorporating new uses. Various strategies of technical interventions can be employed to achieve good results.

Performance-Based Wind Design of Building Envelopes

Tuesday, May 11, 12:00 PM – 1:00 PM ET

ASCE published the Prestandard for Performance-based Wind Design (PBWD) in August 2019. It presents a recommended alternative to the prescriptive procedures for wind design of buildings contained in ASCE 7 and in the International Building Code (IBC). PBWD provides the ability to gain structural economy through enhanced analysis and design techniques. PBWD is intended to rationally reduce damage and losses for wind-design effects. Performance objectives are established at the onset of design and are measured according to their related acceptance criteria.

The prestandard concentrates on structural systems of tall buildings. However, Chapter 8 presents enhanced design criteria for the building enclosure. The criteria address enclosures of both high-rise and low-rise buildings. Chapter 8 is intended to advance the performance of building enclosures.

The presentation will provide an overview of performance-based wind design of structural elements. However, the presentation will concentrate on the building enclosure criteria given in Chapter 8. In addition to design criteria, the construction contract administration and post-occupancy inspections, maintenance, and repair will be discussed.

The presenters of this presentation were the authors of Chapter 8. The prestandard can be downloaded for no charge at Prestandard for Performance-Based Wind Design | Books (ascelibrary.org)

Adaptive Re-Use: Technical Challenges and Risk Mitigation

Thursday, May 13, 12:00 PM – 1:00 PM ET

The need for office space declines as existing offices have become more efficiently designed and telecommuting becomes more common. The recent COVID-19 pandemic exacerbated the challenges facing offices and created unexpected opportunities. At the same time, the demand for high-density housing within urban centers continues to increase. These factors have created opportunities to utilize adaptive reuse as a strategy to convert underutilized office and industrial buildings into residential housing. Adaptive reuse projects can result in distinctive and attractive housing options while at the same time posing a myriad of unique building design and construction challenges. This presentation will focus on design solutions intended to address the unique building enclosure challenges posed by these projects. Presenters will draw from their professional experience designing and investigating both within and outside of litigation the challenges associated with adaptive reuse in order to offer risk mitigation techniques. Presenters will also show how various computer modeling programs and testing protocols can be used to analyze the existing building and assist in the building conversion design. This presentation is intended for building owners, designers, enclosure consultants and contractors to identify problems and solutions. The presentation will contain one design case study and one litigation case study.

Roof Drainage Design 2021

Tuesday, May 18, 12:00 PM – 1:00 PM ET

Restoring Texas’s Historic Art Deco Icon

Thursday, May 20, 12:00 PM – 1:00 PM ET

Dallas, Texas boasts world-renowned architecture including the Hall of State building at Fair Park. This National Historic Landmark, constructed in 1936 for the World’s Fair, is considered the most significant Art Deco building in the State of Texas. To this day, it remains an important centerpiece for the State Fair of Texas, greeting two million visitors annually. Despite its status, continued use has left the icon crumbling and plagued by leaks, putting historic artifacts at risk. Walter P Moore was enlisted to assess the extent of damage to the limestone veneer and determine the sources of water infiltration. Upon completion of the investigation, designs were assembled to repair were the deteriorated limestone veneer, to stop long-term water infiltration at the plaza and basement and roof leaks, replace deteriorated sealant at the historic windows, and determine the appropriate cleaning methods for the iconic, soft, Cordova Cream limestone cladding. Preserving historic buildings also brings additional challenges, including material compatibility, efforts to retain historic building materials, ensuring repairs will not impact the historic aesthetic, and meeting Texas Historical Commission requirements. This presentation will discuss overcoming the challenges of delivering the Hall of State project in time for the world-renowned Texas State Fair.

Design-Build: The Good, the Bad, and Strategies for Avoiding the Ugly

Tuesday, May 25, 12:00 PM – 1:00 PM ET

There are unique risks and opportunities in a design-build project. From predesign through construction completion, the speaker will discuss benefits and challenges of this delivery method and how to increase the likelihood of success for all participants.

How does a building enclosure consultant’s role differ from a design professional in responsible charge? What can happen if an owner fails to live up to its contractual obligations? How can a contractor mitigate risk and increase the likelihood of success by utilizing their design professional, building enclosure consultant, and sub-contractors effectively?

Lawsuits are common and risk-reward equations are complex. This presentation will provide valuable insights from real-life litigation matters.

Whether you are an architect, owner, contractor, or consultant, understanding the reasons projects fail as well as how they can succeed will allow you to enter into a design-build project with useful knowledge and an increased likelihood of success.

Foundation Waterproofing Replacement: A Historical University Building Case Study

Thursday, May 27, 12:00 PM – 1:00 PM ET

Many commercial and institutional buildings outlast the effective life of their original foundation’s waterproofing and drainage systems. They suffer from water infiltration which can deteriorate building components and disrupt building operations. In these instances, owners face a choice to conduct repairs to manage water infiltration at the interior or prevent water infiltration from the outside of the building. Some owners require the reliability of exterior-applied replacement below-grade waterproofing to meet building use or service life requirements. The design and construction of these remedial projects typically requires extensive excavations and presents several architectural, civil, geotechnical, and structural engineering challenges.

We will present a summary of the recently completed Krieger Hall below-grade waterproofing and colonnade repair project at the Johns Hopkins University (JHU). We will briefly review the background and investigation of below-grade leakage and masonry distress of the historic mass-masonry structure. We will focus on the collaborative, multi-disciplinary approach taken to design repairs to the building enclosure, structural, and subsurface drainage systems. Our case study will focus on the unique challenges associated with performing work on an urban university campus and integrating modern foundation, plaza, and wall waterproofing while maintaining the historical fabric of the nearly century-old structure.
