Live from atop multiple completed surfaces, it’s the Thermal Mass & Buoyancy Ventilation Research team! They’ve been busy staying grounded and flooring onlookers! The team has nearly completed the Cooling Porch and fully installed the Test Buildings floor and walkway. Let’s get right into it!
Making a Mosaic
After properly stacking the Cooling Porch retaining walls, the TMBV team filled the enclosure with 4″ of gravel. This gravel covers the drain and also acts as a leveling surface for the concrete sidewalk scraps. If it hasn’t been mentioned yet, the final ground surface in the Cooling Porch will be a mosaic of reclaimed concrete sidewalk scraps. These scraps come from a newly replaced walkway in Newbern and will act almost as flagstones.
In order to create this mosaic, the crew labeled and documented the exact size of every piece of sidewalk scrap. They took photographs of the each sidewalk piece with a ruler on top. Next, they sized each one proportionally in the 3D modeling software, Sketchup, where they placed pieces within the cooling porch walls. Afterwards, out on-site, the team laid out all of the sidewalk scraps and prepared to place them in the Cooling Porch.
Finally, one of the three big lifts to erect the SIPs structures is complete! Before Shane of Sweetwater Construction LLC could lift the Test Building floors and walkway into place, the team had to assemble the SIPs. Each floor is comprised of three SIPs panels, two embedded LVL (laminated veneer lumber) beams, and 2′ x 12′ lumber to cap the ends. The embedded beams allow for the cantilever from the 4 columns.
Underneath the Fabrication Pavillion, the team lifted the SIPs atop the gooseneck trailer where they assembled the different parts and pieces. The embedded beams are coated with SIP seal which ensures a waterproof joint. They are also nailed to the panels. The 2′ x 12′ caps have attached joist hangers to accept the LVL beams.
With both floors complete, it was time to lift! Shane with the crane pulled the gooseneck trailer down AL Highway 61 to the other side of Morrisette Campus. On-site, in place, and ready to lift, take a look at the process below!
The whole process took only 4 hours, but many, many months of prep work and design. Stay tuned to see the TMBV test building go up just a fast and hopefully just as smooth!
