The Thompson Library - Ohio State University

Words: Drew Rosengarten

The Thompson Library at Ohio State University is a landmark of historical and architectural significance. Its renovation, completed in 2009, was a comprehensive project that aimed to modernize the facility while preserving its historic character. The project involved intricate masonry work, structural reinforcements, and the integration of modern amenities—all while respecting the library’s neoclassical design.

Scope of Work
The renovation project encompassed a wide range of activities, each critical to achieving the balance between modern functionality and historic preservation.

Masonry Restoration
The Thompson Library’s façade, with its ornate stonework and intricate carvings, required extensive restoration. This included:

Cleaning: Advanced cleaning techniques were used to remove dirt and grime without damaging the original stone.
Repair: Deteriorated stone elements were repaired or replaced. Special care was taken to ensure that the new stonework matched the old in both appearance and texture.
Repointing: The mortar between the stones was carefully removed and replaced with a blend that matched the original in color and composition.

Structural Reinforcement
The project required reinforcement of the building’s original masonry to comply with modern safety standards. Key actions included:

Integration of Support Systems: New support structures, such as stainless steel anchors and carbon fiber reinforcements, were added to strengthen the masonry without altering the building’s appearance.
Foundation Work: The foundation was assessed and, where necessary, reinforced to ensure long-term stability.

Modernization of Facilities
Enhancements were made to improve the library’s functionality while respecting its historic fabric:

Accessibility Upgrades: New ramps and elevators were installed to meet ADA standards, ensuring the library was accessible to all visitors.
HVAC Systems: The heating, ventilation, and air conditioning systems were updated to provide better climate control and energy efficiency, integrated discreetly to avoid impacting the building’s historic aesthetics.

Materials and Equipment
The choice of materials and equipment was crucial in maintaining the library’s historic character while addressing modern needs:

Stone and Mortar: High-quality, custom-cut stone was sourced to match the original masonry. Mortar was formulated to replicate the historic mix in color and texture, ensuring a cohesive appearance across restored and original sections.
Advanced Reinforcement Materials: Stainless steel anchors and carbon fiber were selected for their strength and minimal visual impact. These materials were used to reinforce structural elements without altering the library’s historic look.
Restoration Tools: Specialized tools, including laser cleaning technology and precision-cutting equipment, were employed to ensure meticulous restoration work.

Challenges and Solutions
Several challenges were encountered during the renovation, each addressed with strategic solutions:

Matching Historic Materials: One of the most significant challenges was sourcing materials that matched the original construction. Extensive research and collaboration with historical preservation experts were necessary. Custom stone was procured, and mortar was carefully analyzed and reproduced to match the historic formula.
Structural Integrity: Initial assessments revealed that some of the original masonry did not meet current safety standards. Engineers developed a reinforcement strategy that included hidden support systems to strengthen the structure while preserving the visual integrity of the building.
Weather and Environmental Factors: The renovation faced delays due to adverse weather conditions and environmental impacts. To mitigate these issues, project scheduling was adjusted, and temporary protective measures were implemented to safeguard ongoing work and materials.
Preservation of Historic Features: Integrating modern amenities while preserving historic elements required careful planning. Collaboration with preservationists ensured that new installations, such as lighting and climate control systems, complemented rather than conflicted with the library’s historical design.

Design Aspects
The renovation preserved the library’s neoclassical design, focusing on several key aspects:

Facade Restoration: The restoration work meticulously preserved the library’s grand columns, ornate carvings, and decorative elements. Each detail was carefully cleaned, repaired, or replaced to maintain the building’s historical character.
Integration of Modern Elements: New architectural elements, such as improved lighting and climate control systems, were integrated in a way that harmonized with the library’s historic features. The design team selected modern materials and technologies that complemented the building’s original aesthetic.
Accessibility Enhancements: The installation of ramps and elevators was designed to be both functional and unobtrusive. These enhancements ensured compliance with accessibility standards while blending seamlessly with the library’s historic appearance.

Timeline
The Thompson Library renovation followed a detailed timeline, reflecting the complexity and scale of the project:

Planning and Design (2007): This phase involved initial assessments, design development, and coordination with historical preservation authorities. Detailed plans were created to address both the restoration needs and the integration of modern amenities.
Restoration and Renovation: The main renovation work included cleaning and repairing masonry, reinforcing the structure, and installing new systems. This phase also involved careful coordination to minimize disruption to the library’s operations.
Final Inspection and Opening (2009): The final phase included thorough inspections to ensure compliance with safety standards and historical preservation guidelines. Once inspections were completed and any final adjustments made, the library was reopened to the public.

Conclusion
The Thompson Library renovation project successfully achieved a delicate balance between preserving a historic landmark and upgrading its functionality for modern use. Through meticulous planning, skilled craftsmanship, and innovative solutions, the project not only revitalized the library but also ensured that its architectural legacy continues to be appreciated by future generations.
Lang Masonry is proud to be a part of the collaboration among architects, engineers, preservationists, and construction teams that were instrumental in overcoming challenges and delivering a result that honors the past while embracing the future.
