Sitting Surfaces

Stack of the cut timber, each bench will utilize two eight by eight cypress sections for the sitting surface

You may remember from the previous post, talk of benches and installations of the legs. Well, here we’ve got the sitting surfaces. The team is using heavy timbers leftover from the Newbern Town Hall project as the bench surface. In the images above, Caleb and Claudia are cutting the wood to 6 ft length which will be sanded, routed, and sealed. Next, they will attach the timber to the quarter-inch plates that make up the structure of the legs. During this time, they also excavated and poured the footing for the last bench!

The Completed Puzzle!

Folks, it is time to cut a rug on the best dance floor in Greensboro! After many, many days working on the brick pad, all bricks have been cleaned, placed, leveled, and sanded!

After placing all the bricks, the team removed the temporary wooden edging. Next, they installed the quarter-inch, galvanized steel edging. Some of the off-the-shelf pieces needed length modification so the team cut and welded them on-site.

After securing a corner at the right level, the team installed the first 16′ piece of metal edging. They adjusted the following legths to alighn with the first piece. The metal was clamped together and staked in placemet at the corners. Scrap wood was used to keep the edging flush against the bricks until backfilled. After all the edging was in place the bricks along the edge were readjusted.

Once everything was in place, more sand was spread between all the bricks

Construction at the courtyard is coming to a close so make sure to stay updated as it nears completion!

Who said there is such a thing as, “too much concrete”? Definitely not the Horseshoe Courtyard Project team! In the last two weeks, Caleb, Claudia, and the 5th year and Graduate Student helpers poured concrete for the sidewalk extension, wall footing, and the wall mock-up. Oh, the wall? It’s made of concrete. Let’s see how they do it!

Team assembling concrete formwork — Team making formwork

In one action-packed afternoon, the team poured the concrete sidewalk extension and the footing for the 9′ concrete entry wall. Both are located at the north end of the courtyard site. Special formwork was made to help keep the footing rebar in place. This rebar extends out of the footing and will be cast inside the wall. Special attention was also paid to the sidewalk extension by giving it a broom finish.

Mock-up # 13: The Concrete Wall

Next up, the thirteenth mock-up. This mock-up tested the finished quality of the concrete for the 9′ wall. The team experimented with how much the concrete needed to be vibrated to create a smooth surface and where to locate seams. It was also important to practice the overall process of making out-of-ground formwork and pouring into it.

Due to the dimensions of a single melamine sheet, a wood composite board with a plastic coating, no single sheet will cover the whole face of the concrete wall. Therefore a couple of options were tested using two, 2′ x 2′ panels. Each panel face tested a different option; single sheet, horizontal seam, vertical seam, and a combination of the two. Silicon sealed the joints and corners and liquid nails connected the different segments of the melamine board together. Once the concrete cured and the forms removed, the team decided horizontal seam would be best.

Only the Corner Left

After removing the formwork for the recent sidewalk extension, the last flat screen on the east side was ready for filling. Caleb, Claudia, and TMBV team members planted three more vines, weaved the rope through, and fastened the corresponding steel cables. The corner screen will be finished, once the concrete sidewalk is fully extended, to avoid trampling the plants in the process.

Spring is Upon Us

In the last couple of weeks, the courtyard has seen new colors pop up! The Carolina Jessamine or Gelsemium sempervirens, one of the two vines planted have started to bud. This week, almost all twenty of the Jessamines have bloomed or have buds that will bloom in the coming days. This beautiful vine blooms twice a year, in the fall and spring; and complements the fragrant white blooms of the Confederate Jasmine (Trachelospermum jasminoides), which will make their appearance in a few weeks!

Benches Coming Together

During Neckdown Week, the team and helpers dug and poured two of the concrete footings for the benches. And last week, the corresponding metal legs for the benches were installed. The team hammer-drilled into the concrete and epoxied the threaded rods into place. The base of the benches will be grouted to the concrete at the correct level once the third bench footing has been poured and hammer-drilled. The benches’ sitting surface consists of two eight-inch square heavy timber cypress, leftover from the Newbern Town Hall project, which will provide durability as well as comfort for the user.

Walkway Capped

Finally, the end of the walkway is complete! A new quarter-inch plate was installed into the masonry wall to support the northernmost railing. The process for the installation of the plate was the same as the plates which support the walkway. The main difference being the middle two anchors that extended past the wall plate and attached to the railing aligned with the other railing frame connection point. The corner piece, while singular in its function, follows the same language and rhythm as the rest of the metal. And maintains the two-inch gap in both its connection to the last railing and to the existing ones.
