UNC Bell Tower Development
Thalle involvement began with being awarded the “Advanced Site Package” contract in November 2007, and we achieved substantial completion of the first phase in April 2009. Key challenges on the project included a complex and tight schedule, limited space on-site, vehicular and pedestrian traffic control, limited access on and off the site, and various unknown conditions underground. In addition, Thalle worked through various design changes throughout the duration of the project and were able to minimized subsequent schedule impacts.
Environmental sustainability was a key objective for this project. In order to prevent flooding of the existing downstream storm water system … the new system exits through a storm water detention center comprised of four (4) 10ft H x 10ft W x 120ft L concrete box culverts that were installed side by side underground. The box culverts are encapsulated with clean stone and wrapped with an impervious PVC liner to act as an underground cistern (reservoir). The roof drain collection system is piped to the cistern, and the water collected will be harvested for irrigation and use in the toilet facilities.
Thalle Construction Co., Inc. is proud to have been a part of this important “eco-friendly” project on the UNC campus in Chapel Hill. Ongoing site and building development is critical to the expansion of our higher education facilities in North Carolina. The success of this project stands as irrefutable proof that such work may be accomplished while minimizing impact(s) to our environment. The UNC Bell Tower project is truly a “Go Green” project.
