Meeting Title: 

Historic Terra Cotta Restoration: Guidelines and Details

Location: 

Live Zoom Webinar. Pre-registration is required at the link below.

Presenters: 

Roy Ingraffia

Description: 

This program provides an introduction to terra cotta as an architectural cladding material, its manufacturing, overview of its performance, and methods of installation & repair. Terra cotta, as an architectural material in the United States, was used profusely from the late nineteen century until the 1950's as a durable and decorative material and continues to be chosen as a unique solution for creative cladding solutions. Terra cotta is a high-performance material, however when failure does occur it is generally associated with original detailing, poor building maintenance, and reaction to secondary materials in the wall assembly. Specific information will be provided on repair materials and techniques that are suitable for terra cotta buildings and their various construction types.

Roy Ingraffia is an Associate of the American Institute of Architects (AIA) and a Professional Associate of the American Institute for Conservation of Historic and Artistic Works (AIC). In his role, Roy directs IMI’s marketing, industry development, research, and technical services programs nationwide.

He is an Architectural Conservator with experience in design and contracting capacities and his professional work has primarily focused on the preservation of historic masonry structures through research of traditional materials/methods and development of contemporary restoration techniques. In addition to his work with IMI, Roy teaches the Masonry Conservation Seminar within the Graduate Program in Historic Preservation at the University of Pennsylvania.

October 2020 Monthly Meeting

Time:

Meeting Title: 

Practical Review of Wind Tunnel Testing for Buildings

Location: 

Live Zoom Webinar. Pre-registration is required at the link below.

Presenters: 

Dr. John Kilpatrick, Ph.D.

Description: 

As the complexity of building geometries and façade systems grows, consultants may have reservations about the applicability of code-based methods for design. The performance of novel façade systems may be better understood through a performance-based wind design (PBWD) approach.

Application of PBWD requires wind tunnel generated building-specific wind loading inputs. The measurement of wind loads on façades of buildings can be carried out with a high degree of accuracy in boundary layer wind tunnels, and when incorporated properly into the design these data will lead to more efficient and economical outcomes.

Topics related to the prediction of facade design wind loads are examined in this presentation, including a thorough review of the wind tunnel testing and analysis process, integration of wind tunnel data with local wind climate, internal pressures considerations, and application of the wind tunnel technique to novel façade features and systems. A brief overview of the recently released Prestandard for Performance-Based Wind Design developed by the Structural Engineering Institute (SEI) of the American Society of Civil Engineers (ASCE) will also be provided.

John Kilpatrick, Ph.D., P.Eng., C.Eng., F.ICE, is the Wind Engineering Practice Leader at RWDI and a Principal of the firm. John is a former Chair of the UK Wind Engineering Society, and is a contributing author to the ASCE/SEI Prestandard for Performance-Based Wind Design and ASCE 49 Standard for Wind Tunnel Testing for Buildings and Other Structures.

Postmodern Predicament: A Case Study of the Portland Building Facade Replacement

Location: 

Live Zoom Webinar.

Presenters: 

Erica Ceder, DLR Group

Ian Eikanas, KPFF

Description: 

The Portland Building is an internationally recognized work of Postmodern architecture by master architect Michael Graves. For decades, the building suffered from multiple performance issues leading the City of Portland to initiate a project in 2016 that would comprehensively address existing building performance issues and modernize the building. The project included the addition of a new skin over the existing exterior, creating a weather-tight enclosure with improved thermal comfort and increased daylighting. This case study will explore the challenges related to applying a new envelope system over an existing façade from both historic preservation and structural perspectives.

Erica Ceder specializes in the restoration and rehabilitation of historic properties and has served as Project Architect for a variety of projects listed on the National Register of Historic Places for both public and private clients. Her depth of knowledge in the physical properties of historic building materials is a significant asset, as is her experience in performing condition assessments and making treatment recommendations. Erica brings additional value as an expert in navigating the complex historic approval process.

For more than a decade, Ian Eikanas has worked on a wide variety of projects, from seismic upgrades of historic structures to complex and eye-catching new athletic facilities. Ian genuinely enjoys the collaborative process between the architect and engineer, blending creativity with finite logistics. Recently, Ian managed the structural engineering of the unitized curtain wall design on the 73 story Wilshire Grand Center Tower located in Los Angeles, California. Ian earned both his BS and MS degrees in civil engineering from Washington State University and became a LEED accredited professional in order to bring a deeper understanding of sustainability to the job.

Deconstructing the Masonry Wall: A methodology for wall design specifically for the Northwest

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Tonia Sorrell-Neal

Description: 

This course takes a detailed look at the basic decision-making process for walls in the pre-design and early design stages. Attendees will learn a design approach that quickly and systematically takes them through a series of micro-decisions on a small number (eight or fewer) of subassemblies of the wall, resulting in a well informed system design as well as reviewing The 2018 Masonry Systems Guide, Northwest Edition which standardizes best practices for masonry wall systems design and construction specific to the climate and building conditions in the nortwest. This presentation will introduce the guide's 8 primary masonry based wall systems which include anchored and adhered veneers and structural CMU walls as well as wood and steel backups for each. Also included in the guide and the presentations are costing and budgeting information, thermal requirements and weatherproofing and specifications.

This session will use examples of walls from real projects and walk the audience through the uniquely swift linear decision-making process. It will also discuss development of a wall taxonomy, the curation of a Wall Systems Library, and opportunities for BIM integration.

Tonia Sorrell-Neal serves as the Executive Director of the Masonry Institute of Washington, a statewide construction trade association representing masonry contractors, manufacturers and suppliers; working with brick, block, stone, marble, restoration, PCC and tile. Tonia has more than 20 years of experience in the construction industry as an association director and legislative liaison.

Tonia began her career in the construction industry in 1993 at the law firm of Brown Todd & Heyburn, LLC focusing on construction defect litigation.
