Interior finishes and specialties are being installed and drywall finishing is ongoing. Overhead acoustical panel installation is ongoing. Cabinetry and built-in desks continue to be installed. Culinary equipment is being installed. Signage installation has begun. Restroom accessory installation is about to begin. Tile work, carpet, and other flooring activities are ongoing. Decorative metal railing posts have been installed at the open stairs and perforated panels will be installed in March. Glass railing at floor openings is complete. Three of the five elevators are complete. Cable tray installation, wire pulling, and pipe insulation are nearly complete.
Exterior metal panel activities are ongoing on the upper paseo. Paseo waterproofing is nearly complete and elevated concrete topping slab will be poured soon afterward. Sitework is currently ongoing in the paseo and on the west side. Sidewalks are being installed. Landscaping and finishes to begin shortly.
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.
Construction teams commemorated the topping-out of Rio Grande Campus on Wednesday, January 22. The event marked an important milestone for the project.
On Level 2, exterior wall spray foam was placed on all facades. Welding of steel roof supports was performed at both atriums and a crane erected the remaining roof-level penthouse steel framing. The science lab air handling units also were placed on the penthouse floor. On the south elevation, exterior metal clad wood windows were installed. Exterior window installation is nearly complete, with the exception of some special arched-shaped windows, which are special orders.The transformer vault foundation was poured and concrete back-up walls have been put up. The exterior brick veneer work has commenced.
Inside Rio Grande Campus, Building 1000, crews continue to pull electrical cables and pipelines for plumbing fixtures in restrooms across all floors. At the south atrium, cloud ceiling steel supports have been hung from the steel roof structure. Fireproofing has been sprayed on the steel structure of the penthouse at roof level. Science lab exhaust steel supports are being welded at the roof. Lastly, metal decking has been applied to the penthouse roof, marking the highest point of new structure on the building.
Across the street, next to Rio Grande Building 3000, the emergency generator equipment was placed over the holidays. The concrete back-up walls have been put up on the generator enclosure. The exterior brick veneer work has also commenced.
Gas service is now on in the building and plumbing fixtures are being installed. Overhead utilities are still underway in the southern portion of the building. Restroom tilework is making progress, as well as carpet tile in many office suites and study rooms. Ceiling tile installation has begun and acoustic panels are currently in progress in the main corridors. Stair railings continue to be installed. Millwork, such as cabinetry and built-in reception desks, is being installed.
The building exterior metal wall panel installation is still in progress. Exterior site grading and flatwork have begun.
