SUMMARY:2025 September In-Person Meeting
DESCRIPTION:Chicago’s Role in the Modern Concrete Skyscraper \nPresented Thomas Leslie\, FAIA \nThe current exhibition at the Skyscraper Museum in New York City\, “The Modern Concrete Skyscraper\,” explores the history of this ubiquitous\, but often invisible\, material in high-rise construction from Roman times to the present day.  In it\, the Museum’s Executive Director\, Carol Willis\, and I argue that concrete deserves equal recognition\, alongside iron and steel\, for its influence on skyscraper construction.  \nChicago\, in particular\, played a vital role in transforming concrete from a handmade\, relatively weak craft into the industrially produced\, precisely engineered material that it is today.  Rich with sources of strong aggregate\, there are geological and geographical explanations for our city’s rich concrete history.  But strong relationships with research institutions and industry associations\, the city’s volatile real estate and labor markets\, and a rich tradition of collaboration and knowledge transfer all contributed to Chicago’s leadership in concrete high-rise construction throughout the last half of the twentieth century.  More than half of the roughly 400 buildings taller than 12 stories built in Chicago from 1950 to 1986 were of concrete\, not steel.  Significantly\, six of the ten structures that claimed the title of the world’s tallest concrete skyscraper from 1902 to 1989 were built in Chicago. \nThis presentation\, an expansion of a paper initially presented at the Building Technology Educators’ Society in Spring\, 2025\, tracks the history of concrete skyscraper construction in Chicago\, showing how the material challenged the more recognized steel industry and how local organizations—including the CCHRB—played key roles in pushing concrete technology to new heights. \nAbout the Presenter: \nThomas Leslie\, FAIA\, teaches building science\, history\, and design at the University of Illinois\, Urbana-Champaign.  After practicing with Norman Foster and Partners\, London\, he held visiting or permanent faculty appointments at the University of Technology-Sydney\, Australia\, the Bauhaus-Universität in Weimar\, Germany\, the Università di Bologna Alma Mater Studorium\, Iowa State University\, and the McCormick School of Engineering at Northwestern University. \nLeslie is the author of Louis I. Kahn: Building Art\, Building Science (Braziller\, 2005)\, Chicago Skyscrapers\, 1871-1934 (University of Illinois\, 2013)\, Beauty’s Rigor:  Patterns of Production in the Work of Pier Luigi Nervi (University of Illinois\, 2017).  His latest book\, Chicago Skyscrapers\, 1934-1986 (University of Illinois\, 2023)\, received the 2024 Pattis Family Foundation Chicago Book Award from the Newberry Library\, presented annually to “a book that transforms public understanding of Chicago\, its history\, or its people.” \nLeslie was the Booth Family Rome Prize Fellow in Historic Preservation at the American Academy in Rome in 2013-2014.  He was elevated to Fellowship in the American Institute of Architects for his contributions to architectural education and research in 2018\, and in 2023 was named a Distinguished Professor by the Association of Collegiate Schools of Architecture. \nThis meeting will take place at: \nWaterview \n350 W Wolff Point Plaza\, 15th Floor\, Chicago\, IL 60654 \nThe committee meeting will start at the usual time 5:00 pm at the Waterview Restaurant.  Afterwards\, at approximately 6PM\, the business and technical presentation will be provided in the Western Stage House Room located on the 14th Floor. \nDo you have a program you would like to share with the committee\, please feel free to reach out to our program coordinator at jose.estrada@clarkdietrich.com

SUMMARY:2025 November UPDATE - NOV 13
DESCRIPTION:Cook County Hospital Adaptive Reuse\nCook County Hospital Adaptive Reuse – SOM \nPresented by:\nMark Nagis\, AIA\, LEED AP\, NCARB\, Design Principal / Skidmore\, Owings & Merrill (SOM)\nIan Kaminski-Coughlin\, AIA\, Associate Principal / Skidmore\, Owings & Merrill (SOM) \nProject Info:  New life for a city landmark\n\nOriginally completed in 1914\, the Cook County Hospital building is a designated Chicago Landmark and once stood as the symbolic heart of the Illinois Medical District healthcare community. Vacant for nearly two decades\, the building had fallen into a severe state of disrepair and was threatened with demolition. Instead\, SOM led a design-build collaboration for general contractor Walsh Construction\, with Wiss\, Janney\, Elstner Associates and interior designers KOO\, to carefully preserve\, restore\, and adapt the former hospital building to meet the changing needs of the neighborhood with a new hotel\, food hall\, medical offices\, and community spaces. \n\n\n\n\n\n\nRestoration and reinvention\nWhen the rehabilitation project began in 2018\, deferred maintenance\, exposure to the elements\, and vandalism had caused severe deterioration to the exterior and interior of the building. The restoration work focused first on repairing the neoclassical-style exterior\, which involved the replacement of more than 4\,500 pieces of terra cotta on the facade. \nA sliver-thin canopy of steel and glass marks the entrance to the building\, replacing a former bulky addition that diminished the integrity of the historic facade. Inside\, SOM restored the lobby to its original height of 25 feet. Original red terrazzo flooring and ornate Beaux-Arts molding immediately evoke the building’s original grandeur. SOM and KOO took advantage of the building’s relatively thin footprint to configure 210 hotel rooms filled with natural light. Some of the more unusual spaces within the former hospital\, including lofty operating rooms\, were transformed into distinctive guest rooms. \nPresenters:\nMark Nagis\, A collaborative and empathetic leader in SOM’s Chicago studio\, Mark Nagis champions an approach to design rooted in team building and mentorship\, characterizing his design process as an ongoing\, collective conversation between designers\, clients and consultants. Mark’s expertise ranges from large-scale mixed-use projects\, to life sciences\, commercial and hospitality\, as well as the applications of parametric design and digital technology in architecture. \nMark’s project work includes the Bronzeville Innovation Center\, a new hub for healthcare innovation and a cornerstone of the Bronzeville Lakefront master plan\, an expansive lakeshore site on Chicago’s South Side. He also led the design for the adaptive reuse of Cook County Hospital\, transforming a severely dilapidated former hospital and Beaux-Arts landmark into a vibrant\, mixed-use hub for the surrounding community. \nIan Kaminski-Coughlin\, lead multidisciplinary teams towards integrated\, innovative\, and sustainable solutions across scales and project types. We put buildings together here at home in Chicago and globally that make the world better. \nExtensive experience across transportation\, mixed-use\, hospitality/residential\, commercial\, higher education\, adaptive re-use functional markets\, Business Development and Practice Management. \nThis meeting will take place at: \nSkidmore Owings & Merrill (SOM)\n224 S. Michigan Avenue\, Suite 1000\nChicago\, Illinois 60604\, USA \nThe committee meeting will start at the usual time 5:00 pm with drinks and appetizers. At 6:00 pm we will adjourn for our business meeting and technical presentation. \nDo you have a program you would like to share with the committee\, please feel free to reach out to our program coordinator at jose.estrada@clarkdietrich.com

SUMMARY:2025 December Monthly Meeting
DESCRIPTION:How Deferred Submittals / Delegated Design has evolved for high-rise construction \nPresented: Terrence McDonnell\,  PE\, SE\, PEng\, SECB.  Principal\,  CTL GROUP\nDaniel A. Dorfman\, Partner\, Chair\, Fox Swibel Levin & Carroll\, LLP \nHigh-rise buildings are filled with various design professionals at multiple stages.   For the design team\, but what about the design professionals on the contractor’s team?  Of course\, we are speaking about DELEGATED DESIGN. \nAccording to some legal experts “Design Delegation is the assignment of responsibility\, by the provision of performance criteria\, for the design of a discrete portion of a construction project by the licensed\, professional “Design Team of Record” (the “Delegator”)\, typically through a construction manager or general contractor which is not a licensed design professional\, to a specialty contractor (the “Delegatee”)” \nHow this work is accomplished in practice with regularity from one project to another is worth discussing\, as the authors have noticed a wide variation in the actual practice of specifying and delivering delegated design. \nThe City of Chicago has also taken note of this.  In 2023\, the City of Chicago reached out to SEAOI (The Structural Engineers Association of Illinois) in an attempt to guide Architect\, Engineers\, Developers\, and Building Owners\, for a more consistent expectation of the deferred submittal  / delegated design process within the city of Chicago. \nExamples within high-rise design include\, but are not limited to; \n\nCurtain wall systems.\nStructural steel connections.\nArtwork that has not been developed sufficiently to document in the permit submission.\nGlass handrails or cable handrails not fully developed in the permit submission.\nMechanical floor level distribution systems.\nTimber trusses.\n\nThis presentation will review excerpts from various building codes\, AIA contracts\, project examples\, and other relevant materials to provide background on the information available to design professionals\, contractors\, and building owners.  There is more information available than many realize. \nIn addition\, we will review a “DRAFT” document created by the joint committee of the City of Chicago and SEAOI\, whose purpose is to clarify the roles and responsibilities that the City of Chicago expects within a deferred submittal / delegated design process.   We will review the three possible means by which a deferred submittal may be processed.  Finally\, we will facilitate an interactive discussion on the topic of deferred submittals and delegated design with the audience members. \nAbout the Presenters: \nTerry R. McDonnell combines practical engineering expertise with an understanding of modern advancements in the building industry\, committing every day to finding new and innovative ways to turn his clients’ ideas into reality.  Currently\, Terry serves as the overall Division Lead for Building Envelope Services within CTLGroup.   His experience includes providing multidisciplinary projects that deliver cutting-edge solutions for a variety of building types\, including commercial offices\, education\, hospitality\, healthcare\, sports and entertainment\, transportation\, and more. Terry has a passion for pushing the boundaries of practical design and performance of structural glass and glazing systems\, conducting forensic investigations and conditional assessments\, and delivering large-scale adaptive re-use on both modern and historic building types.  Terry also teaches part-time at the University of Michigan and serves as a guest lecturer at various prominent institutions\, including IIT\, the University of Illinois\, the Challenging Glass Institute\, Cornell University\, and Façade Tectonics.  He is active in the architectural and engineering communities\, both in the Chicago area and at the national level. \n  \nDaniel A. Dorfman is a Capital Partner and Co-Chair of Fox Swibel’s Chambers-ranked Construction Law Group and is consistently recognized by Chambers USA as a leading construction attorney. He represents major owners\, developers\, and general contractors nationwide on their most significant projects\, from drafting and negotiating complex agreements to litigating and arbitrating high-stakes disputes. His work includes advising developers\, professional sports teams\, and contractors on the creation of stadiums and large event venues\, navigating risk and resolving challenges to keep projects on time and on budget. Daniel also serves as outside general counsel to many clients\, supporting their ongoing business and operational needs beyond individual projects. \nThis meeting will take place at: \nWaterview \n350 W Wolff Point Plaza\n15th Floor\,\nChicago\, IL 60654 \nThe committee meeting will start at the usual time 5:00 pm in the LaSalle Room with drinks and appetizers. At 6:00 pm we will adjourn for our business meeting and technical presentation. \nDo you have a program you would like to share with the committee\, please feel free to reach out to our program coordinator at jose.estrada@clarkdietrich.com

SUMMARY:2026 January - Old Colony Building
DESCRIPTION:The Old Colony Building – Uncovering where the Skeletons are Buried:  \nPresented by: Kenneth De Muth\, AIA Partner\, Pappageorge Haymes Partners \nA Historic Office to Residential Conversion \nA Chicago Landmark and one of nine nominated Unesco World Heritage site early skyscrapers\, it was renovated in 2015 for student housing. First built in 1893 it was one of Chicago’s supertalls at the time and full of engineering and development challenges. As the nation sank into a financial depression worse than the 1929 crash\, labor unrest\, pollution and city overcrowding were coming to the fore. We’ll explore some of the history and contemporary challenges faced in repurposing this Holabird & Roche designed classic. \n\n\n\n\n\n\n\n\n\n\n\n\n\nWhen the renovation started\, the building had a 60% vacancy rate\, 4 of six elevators non-operational\, Terra-Cotta facade condition problems\, 653 non-functional monumental wood windows\, a failed roof and one open stairwell for the only interior fire exit. The 198ksf renovation has 137 dwellings with ground level retail. A Penthouse facility with terrace were added and compliment the 2nd floor restored banking offices\, now used for administration and gathering space. Two fire escapes were removed from the east facade. A second interior enclosed stair from Basement to Roof was added. Other life safety improvements include a fire alarm and sprinkler system\, diesel emergency generator\, and emergency lighting and voice communication systems. Historic corridor windows and glass doors were upgraded with a fire rated overlay to separate the dwellings and stairs from the corridor. Elevators were repaired using original bronze and iron grilles. \n\nAbout the presenter: \nKen joined Pappageorge Haymes Partners in 1984 and became a partner in 2016. His area of practice and expertise has focused on adaptive re-use and historic renovation particularly of downtown located office conversions to residential and mixed use functions. His leadership on such projects as the Pedro Albizu Campos Apartments\, The Midway Technology Centre\, the Armour Institute\, Stewart School Lofts\, the Motley School Apartments\, Elizabeth Peabody School Apartments\, ARC at Old Colony\, Infinite Apartments\, Metropolitan Tower\, The Buckingham\, Scottish Rite Cathedral\, the Pittsfield Tower Apartments\, and the LEED® Platinum Pomeroy Apartments has been recognized with such distinguished awards as the J. Timothy Anderson Award for Historic Rehabilitation\, the Richard H. Driehaus Foundation Preservation Award\, the Urban Land Institute Chicago’s Vision Award\, and the Chicago Landmark Award for Preservation Excellence. \n\n\n\n\n\n\n\n\n\n\n\n\nThis meeting will take place at: \nWaterview \n350 W Wolff Point Plaza\n15th Floor\,\nChicago\, IL 60654 \nThe committee meeting will start at the usual time 5:00 pm in the LaSalle Room with drinks and appetizers. At 6:00 pm we will adjourn for our business meeting and technical presentation. \nDo you have a program you would like to share with the committee\, please feel free to reach out to our program coordinator at jose.estrada@clarkdietrich.com

SUMMARY:2026 February Residential Building Study
DESCRIPTION:The Single-Exit Residential Building Study for the State of Minnesota \nPresented by:\nCarl Baldassarra\, PE\, FSFPE\, Senior Principal\, Fire Protection\, Wiss\, Janney\, Elstner Associates\, Inc. & Nicholas Ozog\, PE\, MSFPE\, Associate Principal\, Fire Protection\, Wiss\, Janney\, Elstner Associates\, Inc. \nThe potential increase in the story height of single-exit stairway multi-family residential buildings has recently received national attention as a means to help alleviate the housing shortage in the United States. Some housing advocates have cited the current limitation on single-exit stairway buildings as a factor affecting the cost of construction of multi-family buildings that could purportedly be addressed by increasing the allowable height and area for single-exit stairway buildings\, resulting in reduced construction costs\, more usable floor area\, and more flexibility for infilling urban lots. Various cities and states have made changes to their codes to allow taller and larger residential buildings with a single exit stairway\, largely based upon professional judgement and anecdotal information. \nThe State of Minnesota legislature mandated a study to evaluate taller and/or larger multi-family buildings with a single-exit stairway serving buildings up to seventy-five feet in height with a goal of maintaining the level of risk to be less than or equal to what is currently accepted by the State’s building code. This type of analysis had not been conducted previously. The State also created a Technical Advisory Group (TAG) that consisted of architects\, code officials\, developers\, firefighters\, fire marshals\, fire protection engineers\, and housing experts to help guide the study. In the past\, input from this broad group of stakeholders was not always sought. \nABOUT THE PRESENTERS \nCarl F. Baldassarra\, PE\, FSFPE \nCarl is a Senior Principal and Manager of the Fire Protection practice at Wiss\, Janney\, Elstner Associates in Chicago/Northbrook\, Illinois. Prior to that\, he was Executive Vice President at Rolf Jensen & Associates\, and President of Schirmer Engineering Corporation where he worked for more than thirty-five years. Over his career\, Mr. Baldassarra has served on many NFPA and ICC technical committees\, including the ICC Ad Hoc Committee on Tall Wood Buildings\, responsible for development of the first comprehensive criteria for mass timber construction in the 2021 edition of the IBC. He has also served on the ICC Code Technology Committee; and technical committees for Fire Code (NFPA 1)\, Automatic Sprinklers (NFPA 13)\, Smoke Control (NFPA 92)\, and Life Safety (NFPA 101). \nNicholas E. Ozog\, PE\, MSFPE \nNick Ozog is a licensed fire protection engineer with 20 years of experience\, and is an Associate Principal with Wiss\, Janney\, Elstner Associates in Chicago\, Illinois. Since joining WJE in 2016\, Nick has conducted fire/life safety analyses of new and existing buildings of virtually all building types\, from high-rise buildings like the Willis Tower to health care\, to public assembly\, such as the Wintrust Arena\, developing technically-based alternative methods and materials when necessary to support the goals of the project. Mr. Ozog’s background also includes fire risk assessments of highly-protected risks such as petro-chemical facilities\, energy storage facilities and other types of industrial facilities. He has also conducted loss investigations and analyses of the roles of sprinkler systems and fire detection systems in those losses. \nThis meeting will take place at: \nWaterview \n350 W Wolff Point Plaza\n15th Floor\,\nChicago\, IL 60654 \nThe committee meeting will start at the usual time 5:00 pm in the LaSalle Room with drinks and appetizers. At 6:00 pm we will adjourn for our business meeting and technical presentation. \nDo you have a program you would like to share with the committee\, please feel free to reach out to our program coordinator at jose.estrada@clarkdietrich.com

SUMMARY:2026 March Meeting at RATIO
DESCRIPTION:Clear\, Flat and White: High Façade Design in the Age of Uncertainty \nPresented by Steven Pantazis\, AIA\, LEED AP BD+C\, High Rise and Technical Design Leader\, RATIO \nOpening Fall of ’26\, the 143\,500-square-foot center expansion\, including a new 800-room Signia by Hilton\, the tallest hotel tower in Indianapolis and the first to be built there in more than 15 years\, atop a 50\,000-sq.-ft. ballroom to create an unrivaled convention package. The new property stands 38 stories\ntall topped by a sky lounge bar with skyline views on a podium set into the urban fabric with a sensitivity belying its sectional complexity. \nFrom the outset\, the Design Team established several criteria for the structural-glazed unitized curtain wall design including minimizing glass distortion such as roller wave and pillowing. Consisting of an alternating pattern of white and clear glass\, it was important for the glass to be low-iron to limit the green hue in the vision panels but especially the opaque white panels to keep them looking as white as possible. The system design includes the fabricator’s standardized system as well as bent glass on the corners and a creased façade with the system canting out of vertical in opposite directions on either side of the crease. We will walk through the visual and technical design considerations and ultimately the final glass makeup driven by performance and aesthetics prioritizing minimizing glass distortion. The presentation will include working with and deviating from the fabricator’s standardized system\, leveraging the visual mock-up for glass selection and the performance mock-up which included an expanded scope to incorporate deviations from the standardized system and the façade lighting feature. Laboratory and in-situ testing procedures will be presented including air and water infiltration and deflection limits. Lastly\, we will\ndiscuss the challenges of obtaining a high-quality glazed curtain wall system in an environment beset by the challenges of financing and supply chain uncertainty to provide the Owner with a striking modern addition to the existing convention center. \nLearning Objectives: \n\nAesthetic and performance considerations in glass selection and curtain wall unit makeup\nUnderstand the performance and cost differences between curtain wall and storefront\nEstablish mockup and testing procedures to protect the Owners’ interest\nAdapt to uncertainty by adjusting material and fabrication sources\n\nAbout the presenter:\nSteven Pantazis is the Technical Design and High Rise Leader for RATIO. His projects have been built in\nSouth Korea\, Dubai and Russia. Since 2004 his first high rise projects in Chicago’s Lakeshore East set his professional trajectory specializing in the humanistic integration of large\, complex\, multipurpose\ndevelopments into the urban fabric with an emphasis on sustainability and human scale. Steve is a member of the AIA\, Council for Tall Buildings and Urban Habitat\, Urban Land Institute and the Chicago\nCommittee for High Rise Buildings. \nThis meeting will take place at: \nRATIO \n30 W Monroe Street Suite 500\,\nChicago\, IL 60603 \nDo you have a program you would like to share with the committee\, please feel free to reach out to our program coordinator at jose.estrada@clarkdietrich.com

SUMMARY:2026 June Jeddah Tower
DESCRIPTION:Jeddah Tower Restart- Picking Up From Where We Left Off \nPresented by: \n•Gordon Gill\, FAIA RIBA\, Partner\, Adrian Smith + Gordon Gill Architecture\, LLP\n• John Peronto\, SE\, PE. CENG\, EUR ING\, FISTRCUTE\, FICE\, F.ASCE\, LEED AP\, Managing Principal Thornton Tomasetti\, Inc\n• Mehdi Jalayerian\, PE\, LEED AP\, ASHRAE Life Fellow\, CTBUH Fellow\, Senior Principal\, Stantec;\n• Peter A. Weismantle\, FAIA RIBA\, Director of Supertall Building Technology\, Adrian Smith + Gordon Gill Architecture\, LLP \nWork on the Jeddah Tower was suspended in February 2018 at a point when the core was at level 63 or about 250 meters above grade. On February 1\, 2023\, Adrian Smith was contacted by HRH Prince Alwaleed bin Talal and told that they intended to potentially replace the contractor\, Saudi bin Laden Group\, and restart construction immediately. On a follow-up call\, the prince’s assistant\, Talal Al Maiman\, noted the four “pillars” for the restart: \n\nSoonest restart\nRetain SBG\, if only for the structure\nHire a competent contractor to assist (or take-over) by re-tendering the project\nTime vs. Cost will be a JEC decision\n\nApproximately 24 months later\, Saudi bin Laden Group\, took repossession of the site and recommenced construction on the tower.   Recently returned from their first site visit since 2017; the design team\, Thornton Tomasetti (Structure)\, Stantec (Building Services) and AS+GG (Architecture and Interiors) will bring the audience up to date on progress\, potential updates to the design and the challenges of restarting a project based on construction documents more than a decade old and having the soon to be completed tallest man-made structure on the planet address the design impacts from the existing concrete structure curing for ~8 years\, as well as as-built conditions due to the pause. \nThis meeting will take place at: \nAdrian Smith + Gordon Gill Architecture\n30 West Monroe\, Suite 400\, \nChicago\, IL 60603 \nThe committee meeting will start at the usual time 5:00 pm with drinks and appetizers.
