um, which provides parking under the office, living, and plaza spaces. With this increase in density and the subsequent parking space increase, Phase II necessitated a re-analysis of the development’s traffic impact. The team needed to ensure that the proposed changes wouldn’t cre- ate any traffic issues and verify that the number of proposed parking spaces, both off- and on-street, were adequate to meet the needs of the development. This re-analysis and subsequent review led to improve- ments on both Marlee Lane and Brookwood Drive. For Brookwood Drive, the road was redesigned with improved features such as special lighting, roadway design to calm traffic, and safe pedestrian access to the Titletown district. According to Roloff the design and construction of the podium was counter to the typical structural engineering process. Roloff points out that during the typical structural engineering process, you start from the top and work your way down to the foundations. However, due to project requirements, the podium had to be constructed before Titletown Flats. Through early dialogue with the client and architect, Roloff and his team at raSmith developed a conceptual design for the Titletown Flats building. Using this conceptual design model, they better understood the magnitude of the loads imposed upon the podium slab by the Titletown Flats building. As such, Roloff and his team determined that special hold downs were needed to address the lateral loads the building would be subjected to. These hold downs worked to handle the lateral loads the building would face, but they had to be centered in the walls of Titletown Flats. This posed a challenge because Titletown Flats was not far enough along in the design process to know the exact location of those points. To solve this problem, special details were developed during the design and detailing of the podium slab, allowing for a greater out of tolerance placement of the hold downs than industry standards permit. This allowed the team to successfully design the podium and have it under construction before heavy engineering design began on Titletown Flats. The counterintuitive nature of the structural design process for the podium slab brought challenges, and this was further impacted by the dynamic design process and multiple changes that happened early in the design process. Roloff and his team relied on past experience on other projects to overcome this new challenge, setting “design crite- ria since other facets were in the early stages of project demands.”
Another challenge arose when an additional story was added to the Titletown Flats building after construction on the podium had already begun, making it necessary to redesign the podium slab without stop- ping construction. However, Roloff and his team were able to rely on “flexible design solutions” as they had in Phase I. When Phase II of the Titletown development was opened to the public inAugust 2021, it fulfilled the aspects of “work” and “live” in the over - all goals of its management, allowing people to buy townhouses and rent apartments and office space. This partially alleviates one of the biggest challenges to any stadium development: inconsistent usage. By making the area around the stadium an extended community in which people can live and work while also attracting visitors through entertainment and commerce, Titletown ensures a steadier stream of revenue while also making it an attractive destination for tourists and fans alike.
