Wake Med gets new “heart” with expansion
David Allen Company tackles complicated challenges to bring beauty and functionality to project
Wake Med’s expansion into its new Heart Tower and Children’s Hospital in Raleigh, N.C., incorporated 87 patient rooms, six gang restrooms, and lobby for a total of 37,204 square feet of tile in 15 different tile colors and sizes. The project provided a number of challenges for locally-based NTCA Five Star Contractor David Allen Company (DAC), including adapting tile installation to out-of-level vinyl floors, and a complex grid of tile color and orientation changes in the main lobby.
The patient toilets in the Children’s wing had 12”x24” wall tile with a 1”x2” custom glass accent and vinyl flooring. The general contractor had an issue on a previous project where the vinyl flooring was not cut nicely to the ceramic tile base. To remedy this, the GC scheduled the wall tile installation after the vinyl floor. However, upon inspection after the vinyl floor installation, DAC discovered that almost half of the rooms had floors that were 1/4” to 1/2” out of level. To correct this problem, DAC needed to level the walls by scribing the cove base. This totaled about 2,100 linear feet. This adjustment caused issues with all of the switch plates, which were designed to be installed in the 6” bullnose above the glass accent. The condition in every restroom was different, thus requiring coordination with the electrician for all rooms.
From east to west, the main lobby is 388’ long. It is divided into three areas and consisted of three different 12”x24” tile colors. Every time the tile color changed, the orientation of the tile was rotated ninety degrees but the grout joints still had to align. Plus, every color change was either on a non-parallel line or a radius.
The three lobby sections had to be installed separately with the center section as the last to receive tile. Control lines were critical and difficult to obtain, since the tile contractor didn’t have a clear line of sight from one end to the other. DAC started its control line in the area with the public restrooms that were completed in phase I, on the west side of the building.
Control lines were created heading east down the north and south corridors. When the installation moved into the center section where the building wasn’t parallel, DAC had to transpose the control line into segments. Then the control line was continued in the east section, which is where the installation began. DAC moved west installing tile in the north and south corridors simultaneously. The north and south corridors’ pattern joined on the east side of the building to meet the public toilet tile.
The steel staircase had a 12”x48” step tread, with the 12”x24” tile brick pattern continued from the main floor on the risers and stringer. In combination with the difficulty of the brick pattern on a small stringer, it also had 2” steel glass supports that had to be core drilled through the tile. Precision was crucial in drilling because there was less than 1/8” overlap of the cover plate for the hole. DAC did a couple of field mock-ups for the owner and architect to see how the holes and the pattern looked together on the small stringer. Some of these areas were installed from a lift 15’ high.
Even with the difficulties, DAC often finished tile areas with days left on the schedule.
