Tiger Stadium is located in Baton Rouge, LA, on the campus of Louisiana State University (LSU) and is home to the LSU football team. The LSU Tigers are winners of three NCAA national football championships and 14 conference championships. Construction of the historic stadium began in the early 1920s and opened with a capacity of 24,000. Now Tiger Stadium has increased its capacity to 92,000. The north end zone, constructed in 1936, had undergone minor repairs through the years but was recently experiencing concrete façade deterioration. In 2012, LSU wanted to restore the façade while maintaining the historic look of the stadium.
Laser scanning/imaging was used for acquiring large-scale project data, such as general geometry and existing conflict layout. A visual survey and infrared thermography were used to detect developing spalls in the façade surface. Virtual Design & Construction (VDC) technology provided three-dimensional models for site staging and temporary fencing, completed work, and in-place quantities for as-built documents. The building information modeling (BIM) model was used to communicate the planned schedule sequencing for the concrete restoration.
The restoration program included crack injection, spall repair, and application of a corrosion inhibitor to the repaired façade. Then, two coats of a cement-based coating with a fine texture provided a uniform look for the concrete façade. After the coating was applied, a clear anti-carbonation coating was applied to the surface to help maintain a cleaner look by reducing dirt pickup.
This $1.6 million restoration project was successfully completed on time (within 120 days) with 46,000 safe working hours. It would not have been possible without the advancements the repair industry has made in materials, technology, and overall execution of projects.
