Now that the backfill has been completed, we brought the crane back on site and the garage foundation walls were installed. These walls are the same construction as the basement foundation walls and built by Superior Walls by Advanced Concrete. These insulated pre-cast concrete wall systems have a minimum 5000+psi and were custom built to our specifications. The crane and certified crew put the walls in place in a matter of a couple of hours.
Once the garage foundation walls were in place, the excavator proceeded to backfill the same way he did around the exterior of the house. As mentioned in our previous post, this is done to provide full support and drainage for the exterior walls.
The exterior wall panels above grade were also secured into place. These panels were constructed the same way and with the same material as the first floor house walls. They are pre-engineered and built with 2×6 boards and 7/16 OSB.
We also installed the glulam beams for the garage door headers. Glulam, or glued laminated timber, is a structural timber product of multiple layers of dimensioned timber bonded together with durable, moisture resistant structural adhesive. By laminating a number of smaller pieces of timber, a single large, strong, structural member is manufactured. These are then used as vertical columns or horizontal beams, but can also be produced in curved shapes for archways, etc.
Now that the walls are in place, the house is ready for roof trusses. Roof trusses are delivered to the job site pre-assembled. They are lifted onto the frame of the house by a crane and secured to the house with a specialized fastener called FastenMaster TimberLok heavy duty fasteners. These fasteners are used specifically for roof trusses and replace hurricane ties that are typically used. They also meet all building and safety code requirements.
The house is now ready for roof sheathing. Watch for our next post for photos and details on this phase of the project.
