Upon returning to Newbern, the team continued the metal theme and spent the first day back coating all of the metal elements of the pod with a clear lacquer finish to prevent weathering while maintaining the unfinished look of the metal. Then they made the switch back to working with wood.
With all of the wood for the floors prepped and ready to go, installing the floors was a simple and quick process. Of course, before the wood could be placed, the world’s most substantial termite shields had to be installed. The termite shields comprise of ¼” steel plate welded into a box and are designed to complement the massiveness of the mass timber and concrete foundations.
After the termite shields were siliconed in place, the wood for the floors was placed, a process which took about fifteen minutes. Then the wood was roughly aligned so that the threaded rods could be inserted. Once the rods were in place and lighted fastened, the wood received its final alignment. By far the most time consuming part of this process was tightening the threaded rods as, even with our preliminary tightening, the wood still had subtle warping and cupping that needed to be squished out. The floor installation overall took about five hours, four of which went into tightening the threaded rods.
Stay tuned for the rest of the pod coming after Christmas.

The steel for the spreader angles and plates has been delivered and the team has been working on fabricating those pieces. The plates and angles will run along the walls, floors, and ceilings edges in order to evenly spread the load throughout the wall/floor/ceiling when the threaded rods are tightened down. Each plate and angle has to be cleaned, holes torched, and then coated with a sealant to prevent weathering. Once the steel is finished, the team can begin processing the wood for the walls and ceilings using those plates and angles as templates.
As the pod begins to become a reality, the issue of properly staging the construction process to be as efficient as possible is becoming an important topic. To that end, the team decided to fabricate the trusses before beginning to build the pods so that the roof can be immediately installed once the walls and ceiling are in place to prevent the wood from being exposed to the environment for any length of time. It is to this end that Jim Turnipseed and Turnipseed International have been extremely helpful in this process. Not only was all of the steel for the project donated but the team was also able to use Turnipseed International’s welding shop to fabricate the trusses and other steel elements of the project. It was a welcome break from the wood processing to learn about steel and how to weld.
The whole process only took about 5 days. The team spent the first two days cutting down all the members of the trusses, the purlins, the runners, and the plates. The next day, with the help of the men working at the shop, they laid out the truss design on the warehouse floor and welded together a jig. This allowed the team to easily slide the members of the truss in place then weld together each joint. 2 days later, 11 trusses were completed and transported back to Newbern!
Stay tuned for updates as the team returns to Newbern and puts this steel to good use!
The concrete curbs are cured, the formwork deconstructed, and the gravel laid. The site went from a muddy mess to a modern art installation in just a few days with the addition of four concrete monoliths and a field of compacted gravel. Next the team plans to install the termite shields, which are currently in the process of being fabricating, and then construct the floors!
In other exciting news, all the wood for the floors is prepped and ready to go! The team planed, ripped, chopped, and drilled 122 pieces of true dimension 2×8 timber. After ascertaining the scale of this endeavor, they decided to call around and see if any local mills could help them out with the planing and ripping process. Howard Custom Lumber is currently processing the wood for the walls and ceilings (over 700 pieces of wood!) to save the team a little bit (actually a lot) of time.
While the floors were being installed and wood being processed for the walls and ceilings, the team did a quick structural test on the mass timber loft. On a rainy Friday afternoon, they constructed the loft and loaded it up to make sure it wouldn’t deflected when supported on the extreme edges. The mock up was a success, and the loft design is moving forward.
Stay tuned for the heroic return of the wood and its eventual transformation into the first ever Breathing Wall Mass Timber pods!
