February 2020 | Rio Grande Campus Renovations

Persistent rainy, damp conditions slowed the rate of progress a bit in February, but construction continued to progress well.

Spray foam insulation applied to exterior walls has been completed on levels 1 and 2 and continues on level 3. Drywall installation in the electrical rooms on level 0 is complete. About 80 percent of the electrical conduit and air conditioning ductwork has been run overhead on level 3 and is 95 percent complete on the lower levels.

Construction crews are 25 percent complete with roofing the whole building. Despite the bad weather, the entire roof should be installed by the first or second week of March. Once the roof is complete and attached to the parapet walls, the building will be essentially “dried in,” which allows crews to make much more steady progress inside the building with installing drywall and finishing it in other areas of the building.

Crews are in the process of installing the metal clad wood windows on the inward facing atrium walls in both the north and south atrium. The steel windows are being painted and new glazing is being installed window by window. The atrium steel structural frames are 100 percent installed and the suspended ceiling hangers that provide the backing for the decorative ceiling finishes are also 100 percent installed in both atriums. Construction crews are now ready to start installation of the roof pillows, which will dry-in the atriums when their new roofs are completed. This installation should take about 2 to 3 weeks, pending good weather.

The installation of roof penthouse mechanical equipment is complete. Ductwork and piping is now being installed to connect the equipment to chase ductwork, pumps, and chilled water piping. Hardie-plank siding is also now onsite and ready to be installed on the exterior penthouse walls.

In the core of the building, the central stair is now poured with concrete and able to be accessed. On level 0, the main electrical switchgear is being installed in the main electrical room. Electrical lines are being run through pathways underground from this room over to the newly constructed Austin Energy (AE) vault at the northwest corner of the Annex in the north parking lot. The vault is complete and waiting for AE to deliver and install new transformers. This work is also pending the completion of new electrical lines being buried in trenches cut into 13½ Street, which is work being performed by a separate AE subcontractor. These lines will connect the primary AE electrical cabling under Rio Grande Street that serves the whole area to the vault to help establish permanent power for the building. This work will take another 2 or so weeks to complete and the building is expected to have permanent power around April 1.
