2.5 AIA Health/Safety/Welfare Learning Units

How can you make sure that you are making the best decisions when you are planning a preservation, restoration or rehabilitation project? Successful historic preservation projects come from understanding root causes of building problems, choosing appropriate treatments and creatively fitting your building program with the physical resource. Like an artist who can inspire others with a vision of what could be or a skilled doctor who carefully diagnoses ailments before prescribing remedies, we should treat our unique examples of built heritage in the same loving fashion. Case studies will be presented including large and small projects of various building types and building materials. This course has been designed for building professionals and building owners. Audience participation and discussion will be encouraged.

Our speakers have collaborated closely with each other on numerous preservation projects which include National Register Properties such as the Nebraska State Capitol and the Gateway Arch in St. Louis.

Learning Objectives

Upon completion, participants will be able to:

  • Identify visual and non-destructive techniques for the analysis of historic buildings/sites based on world-wide case studies.
  • Develop strategies to analyze diverse research sources and contrasting historical data and material evidence about historic buildings/sites and their materials.
  • Improve collaboration on future projects with multi-disciplinary teams to insure effective interventions for historic properties that balance conservation principles and cultural values.
  • Explain best practices to integrate and develop conservation planning and management for traditional and historic project design and implementation.

The building’s exterior is its primary defense against the elements. Careful detailing of repairs can extend the life of historic materials, but careless detailing can often reduce the life expectancy of important historic fabric. This session will explain methods to get repair details done correctly.

Learning Objectives

Participants will learn to:

  • Identify and analyze the failures of traditional, primarily wooden, assemblies of both surviving historic material and those reproduced by modern materials and construction.
  • Develop strategies to manage the primary source of deterioration: water.
  • Recognize the differences in performance and behavior of materials: original, traditional and substitute.
  • Distinguish between restoration and rehabilitation to ensure that the appropriate materials are employed in the most effective way.

11:45 am - 12:30 pm Lunch

12:30 - 1:30 pm TBC286 Investigative Technology on a Traditional Roof

Instructors: Susan Turner, FAIA and Historic Preservation Leader and Robin Whitehurst, AIA and Principal; Bailey Edward, Chicago, IL

1 AIA Health/Safety/Welfare Learning Unit

Built in 1907 by architects McKim, Meade and White, with a 1911 addition designed by William Carbys Zimmerman, the slate roof on the English Building at University of Illinois Urbana-Champaign’s (UIUC) campus was at the end of its useful life. The building is listed on the National Register of Historic Places and is known for its decorative cupola, copper clad domes, colonnade, decorative masonry and other ornamental aspects.

This presentation will describe the process of the design into working drawings of the roof replacement, focusing on techniques which can be used to improve other projects. It will describe the investigation needed to develop a scope of work that could meet the University’s tight budget. Laser scanning of the entire building will be highlighted to show its usefulness in identifying structural issues and enhancing the accuracy of details and cost take-offs. The application of infrared thermography, destructive testing, and borescope investigations will be explained to demonstrate how non-destructive testing can reduce change orders.

The application of the WUFI model will be explained. This informed the placement of insulation in the existing conditions of the roof. Through these techniques, structural issues were identified, and corrective measures developed. The design approach for the replacement of the roofs, and repair of the deteriorated masonry, will be discussed. Energy efficiency, addressed through a variety of insulation approaches, will also be explained. The research completed to locate matching slate with the original color, size and texture, along with the specification will be outlined. And finally, while no owner wants a new roof, it will be demonstrated that the University improved the safety of the public and increased operating energy efficiency for the occupants.

Learning Objectives

Participants will learn to:

  • Apply WUFI energy model to existing construction to understand methods to improve insulation.
  • Use a dew point calculation in locating the vapor barrier plane and how that is affected by location and thickness of insulation.
  • Apply laser-scanning as a tool for improved detailing, scoping, and costing.
  • Employ lessons learned on this project to most other slate roof projects.

1:30 - 2:45 pm TBC287 The Restoration of Unity Temple

1 AIA Health/Safety/Welfare Learning Unit

Instructor: Robert Score, AIA, Harboe Architects, Chicago, IL

Frank Lloyd Wright’s 1908 Unity Temple in Oak Park, IL is considered a masterpiece of modern architecture. The 8,000-sq.ft. structure is significant not only for its design but also because it is one of the first poured-in-place concrete buildings. Until this point, poured-in-place concrete had been used primarily for commercial buildings.

Time and deferred maintenance had taken its toll on Unity Temple. In 2000, the Landmarks Preservation Council of Illinois (now Landmarks Illinois) put Unity Temple on the Illinois' list of Ten Most Endangered Buildings. In 2009 a piece of the ceiling fell near the pulpit. Now, the historic temple is looking and operating better than ever, thanks to a four-year, $25-million restoration; this session will present information on the diagnostics and analysis to arrive at treatments for both the exterior and interior projects including the concrete exterior, plaster and paint finishes, interior woodwork and stained glass, lighting improvements, and a new geothermal system for heating and cooling. The construction project took two years to complete.

Learning Objectives

Participants will learn to:

  • Explain the process to match and repair the exterior shotcrete from the 1970s and original concrete.
  • Describe the process to analyze finishes and make treatment recommendations for repair, replacement and cleaning when a building is an important historic landmark.
  • Apply lessons learned from the process to conceal new wiring, heating and cooling and other systems within a significant historic building.
  • Strategize for planning and implementing large scale restoration projects on historic buildings that may take months or years to complete.

2:45 - 3:05 pm Networking Break

3:20 - 5:15 pm TBC288 Restoration of Unity Temple Tour**

1 AIA Health/Safety/Welfare Learning Unit

Tour Guides: Trained Interpreters from the Frank Lloyd Wright Trust and Robert Score, AIA Harboe Architects, Chicago, IL

The Unity Temple (1905-08) represents a defining moment in Frank Lloyd Wright’s early career. Designed in Wright’s Oak Park Studio for his own Unitarian congregation, it is one of the first public buildings in America to feature exposed concrete and is Wright’s greatest public building of his Prairie era. The harmony of the building’s geometric architecture and decorative elements exemplifies Wright’s theory of organic design. Unity Temple announced a new era of innovation in modern architecture.

A National Historic Landmark since 1970, Unity Temple is once again open to the public after completion of a comprehensive restoration. The architects who oversaw the $25 million rehabilitation will supplement the interior tour by responding to participants in an informal Q&A session.

Learning Objectives

Participants will learn to:

  • Explain the architectural significance of this National Landmark historic structure.
  • Evaluate the restoration work by comparing original materials with the repairs.
  • Consider the process of improving the energy efficiency of a Landmark with new lighting, geothermal heating and cooling and new wiring.
  • Gain familiarity with Frank Lloyd Wright’s design intent for the structure, lighting, finishes, craft details for Unity Temple and compare it to other buildings by Wright.
