Completed in 1909, Normal Hall is the second oldest surviving building on the Indiana State University campus in Terre Haute, Ind. Since then, Normal Hall has undergone multiple renovations, including an addition added in 1957. But by 2010, the grand neo-classical building was largely unoccupied and falling into disrepair. The hall maintained its perch at the center of campus, but years of service to its tens of thousands of students had taken their toll.

“We try to preserve the history of ISU here on campus,” says Seth Porter of ISU facility management. “But between roof leaks and other issues, it was becoming an eyesore.” So, the State of Indiana approved a $16 million renovation project and partnered with architectural firm arcDESIGN to bring the building back to life.

“This renovation will return Normal Hall to its rightful place in the center of campus life,” says ISU President Dan Bradley. “The project will provide a valuable new resource to students while preserving and re-energizing a significant historic structure in the heart of campus.”

Aside from the stately Indiana limestone, the building had to be redone from the foundation to the roof. And the history that makes Normal Hall special also made for unique challenges in the design and renovation process.

They Don’t Build Them Like They Used To

“People will say, ‘They don’t build them like they used to,’” says Greg Miller, project manager from arcDESIGN. And in many cases, “It’s a good thing they don’t!”

Normal Hall was originally designed for and used as the university’s central library. At that time in history, after the Civil War and before the 1920s, libraries were built in a certain way. Due to open flames of gas lighting and unreliable supply of electricity, indoor lighting at the time could have been dangerous to a library’s collection. So, libraries were designed to maximize natural light, with plenty of windows, skylights, and even glass floors. Instead of structural walls, Normal Hall’s six levels of bookshelves—or “stacks”—were designed to be structurally self-supporting, independent of the rest of the building.

Miller led the design team through the challenging process of removing the six-level stacks and replacing them with four new floors for offices and building systems. A portion of the stacks system was salvaged and reconstructed, providing the same view patrons would have had more than 100 years ago.

The Biggest Challenge

During construction, crews discovered unstable structural conditions on the north side of the building adjacent to the original six-story stacks system. The entire exterior wall had to be removed and replaced, all while supporting the existing attic and roof nearly 60-feet above the ground floor.

To do this, crews constructed a mammoth 60-foot-high temporary structural system in and through the six-story iron stacks system still in place to support the original attic and roof deck. The north wall was completely removed and reconstructed. Structural steel columns supporting roof trusses were replaced while ends of deteriorated roof trusses were reconstructed in place.

“It was a monumental feat,” Miller says. “It was a great example of teamwork by Indiana State University, design consultants and the contractor.”

The Roof System

For the roof replacement portion of the project, arcDESIGN collaborated with The Garland Company Inc., a leader of high-performance roof and building envelope solutions. Garland worked with local roofing contractor Associated Roofing Professionals (ARP) to install a new modified bitumen roof system with a high albedo coating.

All existing roofing was removed to structure and Garland’s StressPly EUV fiberglass-polyester reinforced, SBS and SIS modified bitumen membrane was installed to provide long-term waterproofing protection.

The roof was then coated with Garland’s Pyramic white, nontoxic, acrylic coating, which helps preserve asphaltic or modified bitumen surfaces and significantly reduces under-roof temperatures to create a more energy-efficient environment.

“ISU has a strong commitment to the environment, and we were able to help them achieve their performance goals while also contributing to LEED credits with our environmentally-conscious products,” explains Rick Ryherd, area manager for Garland.

The largest—and brightest—rehabilitation involved the stained-glass dome atop Normal Hall. The original dome had deteriorated so extensively that, by the middle of the 20th century, the remaining glass panels were completely removed and the dome was completely hidden. A suspended plaster ceiling sealed off the once grand rotunda. “Imagine just a skeleton, an empty dome with only the ribs visible,” said Miller.

The dome restoration began with historic photos, documents and forensic analysis. The glass art featured distinguished educators and philosophers. Some of the original stained-glass panels were recovered from the building, whiles others had to be recreated. Conrad Schmitt Studios, in Wisconsin, restored the stained glass to its former glory. With the stained glass restored, rehab on the rotunda continued. Inside Normal Hall, the rotunda mural was restored and more than 140 light bulb sockets were re-wired to light the dome. Above the dome, a new 40-foot octagonal skylight was installed, along with supplemental lighting. Below the rotunda, 20 original columns that stretch through the open hall were restored with scagliola and paint finishes.

The crew worked to save original hardware and finishes that hadn’t already been lost to time. They were able to restore and replicate plaster moldings and cornices, save original wood doors and casings, and restore the grand marble and bronze staircase. “The general contractor did a great job preserving the historic detail with the extra time they put into restoring this building,” notes Porter.

The Future of Normal Hall

With all the time and effort put into preserving the history, the team did not forget to focus on the future of Normal Hall. The team, starting with arcDESIGN, incorporated the old and the new seamlessly.

For starters, Miller said the design was intended to respect but not imitate the building, which is listed on the National Register of Historic Places. Rather, he said, “the design clearly communicates original versus new construction to patrons.” Miller consulted experts from the team, from historians to a representative from the roofing manufacturer to gather the full scope of the project.

Today, the original stately limestone structure is accentuated by the addition, comprised predominantly of glass and Indiana limestone. The addition houses functional requirements such as stairs, elevators, restrooms and mechanical services, maximizing use of the historic interior spaces.

The renovation was planned and constructed to achieve LEED Certification by the USGBC. Renovation included new HVAC systems utilizing the university’s existing central steam heating plant that runs on natural gas. LED lighting throughout is an energy efficient replacement for the building, originally built with combination gas and electric light fixtures.

100 Years in the Making

Re-dedicated in October 2015, Normal Hall is back in action at the center of campus as home to the university’s Center for Student Success and numerous tutors, counselors and mentors. Below the rotunda, more than 100 years after the building opened its doors, students gather in the university Reading Room and Gallery modeled after the original hall when it opened to students in 1909.

Firestone Acquires Silicone Roofing Systems Provider

Firestone Building Products Company LLC has announced its acquisition of Gaco Western, a provider of silicone roofing systems, waterproofing systems and spray foam insulation. The deal, which includes all assets and operations held by Gaco, closed April 3, after a definitive agreement was signed and announced earlier this year.

The acquisition allows Firestone to introduce even more options to customers with Gaco’s silicone and acrylic liquid coatings. The enhanced portfolio creates alternative solutions when full roof tear-offs and rebuilds are not feasible, and it presents contractors with products requiring less labor-intensive installation.

“Combining the best of two brands, Firestone and Gaco, represents an opportunity for growth and long-term value as we aim to create new levels of service and innovation in our industries,” says Tim Dunn, president of Firestone Building Products, Bridgestone Americas Inc. “Operations will conduct business as usual across all teams as we begin bringing our portfolios, employees, best practices and distribution platforms together to continue serving as a total solutions provider for our collective customers.”

In addition to expanding Firestone’s roofing product portfolio with silicone polyurethanes, epoxies and acrylic liquid coatings, the deal offers new positions in commercial and residential sectors with decking and waterproofing products that protect pedestrian surfaces, concrete, metal and plywood, and open- and closed-cell foam products which protect and insulate buildings.

Gaco products will continue to be sold under the Gaco brand and will continue to be made at a state-of-the-art manufacturing, research and development facility in Waukesha, Wis.

Financial details of the transaction are not being disclosed.

ASTM Test Method Prevents Air Leakage, Supports Liquid-applied Polymers

A new ASTM International test method aims to prevent air leakage in and around roofs, helping improve energy efficiency, reduce moisture problems and prevent pollutants from entering a building.

“It is critical that each assembly of the building envelope be investigated for air-leakage performance with appropriate standards,” says ASTM Member Sudhakar Molleti. “What cannot be captured in the material and full envelope air leakage testing—the structural strength and continuity of the air barrier assembly—can be quantified in the assembly testing. To achieve energy efficiency of building and to adapt for climate change, comprehensive data of material, assembly, and full envelope air leakage testing are needed. By quantifying air leakage in roof assemblies, this new standard can serve as a platform for supporting code compliance and for constructing energy-efficient and sustainable roof assemblies.”

Molleti, a research officer with more than 10 years of roof assembly testing at the National Research Council Canada, Ottawa, notes roofing membranes are air impermeable but can be compromised by factors, such as lack of continuity of the membrane seams, improper detailing around rooftop preparations, improper selection of flashing materials and improper connection of roof membranes to the exterior wall barrier.

Specifically, this new test method is a laboratory technique to determine air leakage in low-slope membrane roof assemblies and accounts for the wind fatigue expected during the life span of a roof by simulating negative air-pressure differences.

The new standard (soon to be published as D8052/D0852M, “Test Method for Quantification of Air Leakage in Low Sloped Membrane Roof Assemblies”) was developed by ASTM’s committee on roofing and waterproofing (D08).

In other news, a set of proposed ASTM International test methods will help support the growing number of roofing projects that use liquid-applied polymers. The proposed standard (WK40123, “Test Methods for Sampling and Testing Liquid Applied Polymeric Roofing and Waterproofing Membranes that Are Directly Exposed to Weather”) will help manufacturers; testing labs; and the construction industry as they sample, test and compare products. It is being developed by ASTM’s committee on roofing and waterproofing (D08).

The proposed standard includes ways to test liquid-applied polymeric materials that are cured to form roofing and waterproofing membranes that are directly exposed to all kinds of weather. By their nature, these materials are seamless. They are also useful when working with complex surfaces and custom-fit projects.

ASTM Member Philip Moser notes these membranes have been traditionally used for waterproofing of elevated parking decks, but their use for applications like roofing is quickly rising. Moser, a senior project manager specializing in building technology at Boston-based Simpson Gumpertz & Heger Inc., says, “Delivery to the exact point of application in relatively small containers makes these products particularly attractive for small rooftop terraces, congested urban areas and roofs that are not accessible by crane where delivery of larger containers would create logistical problems.”

The test methods would be used by manufacturers and testing labs, as well as the people who write specifications that indicate which test methods should be used to evaluate physical properties.
