All the major flat slab reinforced concrete floors have been poured up to Level 3 in the core of the building. The shoring and formwork was removed last week. The concrete shaft walls for the two elevators have been erected to the roof and topped out. Brick repair and cleaning of the ornamental cast stone continues in both atriums. On the east side, all the window openings have been roughed in with wood blocking and are prepared to receive new windows, which are currently in production and arriving on-site in about a month.
The chilled water pipes have been flushed and a portion of the building now has conditioned air. Interior finishes are progressing. The ceiling grid and light fixtures are beginning to be installed. The glass handrails at the floor openings are being installed. Wall and floor tile have begun. Door frames and hollow metal window frames, as well as glass, continue to be installed. The concrete floors in certain areas have been ground smooth and will be polished. The kitchen hoods are installed in the Culinary area. Meanwhile, the interior southern portion of the building is framed and infrastructure is nearly complete.
All aspects of construction have progressed as the building is large and in various stages of construction from one end to the other. Exterior curtain wall, storefront windows, and doors are being installed, and the building will be completely enclosed in the coming weeks. Nearly all of the walls are framed throughout and a good portion of the lower level walls have sheetrock. Interior storefront windows also are being installed. The chilled water pipes will be flushed soon and conditioned air will be turned on in the northern portion of the building in the coming weeks so that building finishes may begin.
The heart of the college’s fourth ACCelerator is taking shape at Rio Grande Campus, Building 1000 with workers pouring the first- and second-level elevated concrete slabs in the core of the building. To close in the building and keep out the elements, workers will continue to place steel framing, metal floor deck, and concrete topping in floor penetrations that were cut into Level 3 and the roof, which provide openings for mechanical exhaust ductwork and supply air ductwork to pass through.
In June, construction crews completed demolition on the center area structure and formwork for the ACCelerator slab. At the bottom level, steel columns were erected, plumbing and electrical risers were installed, and wall framing and mechanical/electrical/plumbing installation were started. On the first level, stairs were poured at the northeast entrance and underground plumbing on the southeast side was completed. Crews also installed beams and finished steel infill for the roof openings. Activities for July include beginning work on the elevator shaft and filling in the roof openings.
Construction crews continue to work over the summer on the Highland Campus Phase 2 renovation project, including waterproofing exterior openings, pouring sound slabs and ramps, open stair steel installation, and reinstalling permanent fencing around the chiller yard. The paseo stair and the roof connector bridge have been poured. Concrete block walls at the performance hall are completed. Exterior sheathing to strengthen the wall system and provide a layer of protection against outside elements is 90 percent complete with exterior framing and sheathing of the Paseo and south portion of the building still to go. Skylight installation is almost complete.
Underground utility trenching, chilled water piping, and storm pipe installation are ongoing, as are mechanical/electrical/plumbing overhead and in-wall installation, canopy work, and overhead fire protection.
This past month, construction crews also began work on the elevators, plaster in penthouses 1 and 2, and drywall in penthouse 3.
Construction crews continue to make progress on the Rio Grande Campus renovations. In May, shoring — the process of temporarily supporting a building with props during alterations — was completed at the south mechanical room and the elevated slab poured. Slab was also poured at the south multipurpose room. In the center area, the columns and beams from levels 0 to 3 were demolished. Plumbing pipes have been installed underground at the bottom level. In June, new slab will be poured at level 1 north entry and around the north and south chase. Crews will also start steel framing and metal decking at level 2 east entry and do the formwork for the slab in the ACCelerator room.
ACC Highland Campus Phase 2 progress continues despite the wet weather. The roofing on the north building is 95 percent complete and 65 percent complete on the south building, and exterior sheathing is 85 percent complete. In the paseo, exterior framing and sheathing is ongoing. The paseo stairs and roof connector bridge also have been poured. Waterproofing at all exterior openings is complete, minus the paseo area. Concrete walls at the performance hall are currently being installed. Interior framing; sheetrock installation; and mechanical, electrical, and plumbing work are all ongoing. Underground utility trenching is scheduled to begin soon.
Construction work continues to move forward on Rio Grande Campus. Waterproofing has been completed in the north atrium and has commenced in the south atrium. Underground electrical and plumbing also has started in both atriums. Crews have begun concrete removal in the basement corridor for telecom and plumbing trench and roof tear-off. The south mechanical chase slab and the footing between the ACCelerator and the south mechanical room have been poured. Window removal at level 2 has been completed. The photos below show the roof tear-off and pouring concrete in the north atrium.
Construction crews continue work on Highland Campus Phase 2. The structural steel erection was completed in February. Shoring and formwork for the connector bridge and social stair foundation at the paseo have started. The paseo canopy steel has been erected, and the loading dock slab and sidewalks have been placed. One additional chiller and cooling tower have been installed to the existing chiller plant. Steel roof decking is complete and roofing work and wall framing are underway. Drywall installation has begun on the lower level.
