The crews set up sticker boards made of 1-1/4 inches of plywood to serve as a mold as they poured in the concrete stem wall. They are called sticker boards because concrete won't 'stick' to their material. The purpose of the stem wall is to join the foundation of the building with the vertical walls.
Once the concrete stem wall was poured in and the sticker boards were taken off, the crews began to build the CMU (concrete masonry unity) block wall that will reach the top of the new building's second floor. There are two colors of blocks used in the design of this building -- tan and plum. On the top left is a picture of the mortar pumps; mortar is the workable paste used to bind construction blocks together and fill the gaps between them. On the bottom right is a glimpse at the construction plans, showing the measurements of the new building.
The crews work tirelessly, layering block after block and spreading the mortar in-between.
Here you can see the stacks of CMU and mortar trays the crews work with as they build the wall.
Tentatively, the first half of the wall will be complete in 2-1/2 weeks, then they will switch over and build the other half of the wall. The gaps in the walls are reserved for doorways.
On the portion of the work site where the wall is not being worked on, they are installing the plumbing and pipe work for the location of the new healthy cafe. They are also working on constructing the elevator shaft.
It certainly is a busy work site!
