Horseshoe Courtyard

Neckdown part 1

As the semester kicked off to a rainy start, the team took advantage of the sunny days during the neckdown week to get things done on-site! With the help of Charlie, Livia, Hannah, and Jackie, the new waterline trench was dug, and the CMU block walls were scraped clean and prepped for painting.

While digging the trench, the team and crew found an assortment of whole bricks, dead metal pipes, old terracotta pipes, glass bottles, and remnants of an old foundation. The found bricks were stacked and will be used either on the masonry building to cover the metal beam or as part of the brick “rug” in the finished ground surface at the south end.

Up next, fascia and soffit to be primed and wall painted!

Then There Were Eight

After the threaded rods were trimmed, a torque wrench was used to tighten the nuts to HILTI’s requirement, 60 PSI.

Before the team left for the holidays, the walkway structure was all put up! Thanks to Rowe and Jeff’s help the team finished setting up all eight wall plates, and a few days later Devin and Charlie brought some extra muscle and to site. This facilitated lifting and bolting the “arms” and struts into place. The arms, being the assembly of the three horizontal plates welded together, on which the grate will sit. And the strut is the tube that connects the “arms” to the two plate tabs at the bottom of the plate bolted to the wall.

The future main entrance to the walkway, and point where levels were checked throughout the instalation of the brackets.

A 3x4x1/4 inch angle supports the south end of the grate, which is equivalent to only using half of the bracket.

First One down

Check tabs with torpedo level
Check height with site level
Drill 10 inches into building
Check hole is the right depth
Clean out debris
Put HILTI sleeve mesh in wall
Fill mesh with epoxy
Put the threaded rod in
Place washer and nut
Tighten nuts with a wrench
Rods ready to be trimmed

This week the team put up the first plate on the wall! First, they removed the clips from the conduit and strapped them in place to the scaffolding legs. This allowed the team to slide the plates behind the conduit and into place, and temporarily fix them to the wall with washers and tapcons anchors. In order to use the plate as a drilling template. The tapcons were removed once the first set of rods were cured and ready to receive washers and nuts. After all were done, the rods were cut to the desired length and tightened further with a torque wrench.

This week the walkway grate was delivered! Once all the walkway structure is up, there will be dropped in place.

Testing, Testing…

As the team prepared to start installing the walkway structure, a pull-out load test done in order to understand the strength of the brick, and its relationship to the HILTI anchors. The team installed two anchors with washers and nuts at different locations on the wall and tested both to failure load….and they passed!!

Shortly before the team left for Birmingham, the electrical was roughed in. This week, thanks to Mason’s help, it finally became live!

The color for the block walls has been decided, soon be painted grey ( second from the left)

Prepping for walkway structure

In preparation for putting up the wall plates, for the walkway, the Horseshoe Courtyard team set up scaffolding on-site, and ground off the old threaded rods on the East facade. These rods used to be part of the structure of the historic balconies, back in the late 1800s.

Testing jig, and ease of temporary attachment to the wall with Tapcons and washers. Initial leveling of tabs done with string attached to the 2×4.

The team also took a day trip back to the shop to cut the 5/8 inch threaded rods that will be used to fasten the walkway pieces, as well as the footing plates to the concrete. And the 1/2 inch rods that will connect the screens to each other.
