Here you will find information pages on major capital construction projects on campus, as well as a complete list of all construction projects in progress on campus. 

Current construction hotspots on and near campus include:


30th/Colorado Pedestrian Underpass:  This project will provide a number of safety, access, mobility and drainage improvements at the intersection of 30th Street and Colorado, including the installation of a pair of pedestrian underpasses.

  • Beginning March 1 and lasting for approximately 18 months, travelers can anticipate delays at the 30th Street and Colorado Avenue intersection as crews construct two new bicycle and pedestrian underpasses and install additional intersection safety enhancements.
  • The 30th Street and Colorado Ave. intersection will be completely closed to all vehicles and pedestrians from 9/10-9/23. One exception: Route S - Stampede will have limited through access to this intersection Mon-Fri 7am-5pm. Our other Buff Buses will be following a detour route from 9/10 through 9/23 to avoid the 30th/Colorado intersection.

Chilled Water Expansion Project: The renovations of chilled water services through Main Campus will require the closure of various pathways scheduled to continue through November 2022. The closures and detours are subject to periodic change. Pedestrians are asked to be mindful of signage around the area.

These locations will be closed as part of this project:

  • From Sept. 15 - Oct. 26 the sidewalk on the northwest side of Hellems
  • From Sept. 21 - Sept. 28 the walkway crossing the north side of Norlin Quad between Ekeley Science and The University Theater.

Norlin Library to close Sept. 17–18 for crane work

Norlin Library will be closed on the weekend of Sept. 17 and Sept. 18 to remove old cooling equipment on the roof of the building using a crane. The work will begin at 6 a.m. on Sept. 17 and is expected to finish by the afternoon on Sept. 18. There will also be fencing on the sidewalk surrounding the building.


COSINC Laboratory Addition: Renovation of an existing 3,500-square-foot research lab on the ground floor of the Sustainability, Energy and Environment Laboratory (SEEL) building. Project also includes construction of a new highly specialized cleanroom space to support the Colorado Shared Instrumentation in Nanofabrication and Characterization (COSINC) Laboratory’s micro- and nano-fabrication materials characterization program. This new 1,200-square-foot mechanical equipment room is adjacent to the renovated space to support the cleanroom’s high ventilation requirements. 


Engineering Center North Wing renovation: Complete reconstruction of 55,477 GSF (35,000 assignable square feet) contained within two buildings in CU's Engineering Center (EC), which are the former Aerospace Wing (now North Wing) and the North Tower. More information and construction impacts can be found on the project webpage.
