Saturday the 16th came
through and provided a worthy day of work for the sophmore architecture
students build. As the coordinator for group 6 we organized with three of the
members present by 8am to work on site for the whole day. Two platforms of
concrete had to be poured for the feet of the bench system. For this we
transported a series of tools as well as concrete mix and water to the site.
The locaiton of site 6 is approximately half a mile as the crow flies from the
closest building, PSO. The PSO building and parking lot is the location for all
the material and tool storage as well as offsite construction. Taking the trail
system to deliver materials entails a variety of turns, elevation changes, and
rough earth. Delivering as many materials in one trip is key to success with
the limitations of time available on site. We started with the leveling of two
platfroms in the earth to install a prefabricated 2x4 framework to pour the
concrete into. The frames had to be placed in precise locations, square with
one another as well as level. They also had to be centered for the feet of the
bench that is mounted between two posts that hold the roof structure. A series
of checks took place throughout the process, moving the bench over the holes
many of times and adjusting the location and angle to ensure the pours would be
perfect in the end. Afte the earth was level, square, and tamped down we added
a light layer of gravel. The framework sets freely above the gravel, with
additional gravel placed inside the frame and dirt packed around the outer
edges. Next came the cement, mixed in a wheel barrow from 40lb bags and water
delivered in 5 gallon buckets. The students were quick to learn mixing anything
more than one bag at a time wasn’t worth the effort. Mixing the concrete can be
difficult to get the perfect mix of water to aggregate. After a series of
trials and mixing opportunities for each of them they had a pretty succesfful
system of mixing to installation. The slabs were poured and construction on the
signage began. A few minor items had to be completed on the roof systems and
structure as well. Lunch was near and the two other participants in group 6
were arriving from previous obligations as well. The team took this opportunity
for a return to PSO to regroup, acquire additonal materials, and eat their
lunch. After the lunch break we returned to the site and split into two groups.
A team of two and I started installing the roof and the reamaning bolts and the
main structure. The other three started installing the concrete block bases and
signage pieces. The signage has a very simple yet unique design system. Four
concrete blocks burried in the earth with just a few inches protrduing hold the
4x4 posts that are attached to the signage. Two posts are mounted between two
2x6 treated boards on each side. The 2x6 boards are also knotched and hold 5
cedar boards that span between the posts. These cedar boards will hold the
signage being produced by Touch of Nature. Completing the signage on site was a
very difficult process with the earth not being level or flat. This called for
a plan of action on site and the installation of the first four blocks, level
and square with one another. After this was done each of the four signs wiere
constructed on top of the blocks and bolted together. From there each piece was
moved to its particular location and the earth was marked for the digging and
installation of the concrete blocks at each signage location. The day was
drawing to and end so we finished with the construction of the signage pieces
and marking of the earth for excavation.
