135 Sunset Harbour

August 30th, 2012

Babb Custom Homes began this morning to set walls on a new structure in Sunset Harbour, North Myrtle Beach. I arrived onsite at 10:30 am so you can see the progress accomplished in that brief period of time. We have been dodging rainstorms locally as Tropical Storm Isaac blows up the coast of the Atlantic. Putting together consecutive productive days has been more than a challenge for area builders, but the brief respite allow this component construction home to come together nicely. With limited space on the lot, tightly scheduling wall components, building materials, and trusses is essential. The wall panels and bracing lumber arrived yesterday, with the floor trusses and 3/4″ T+G floor plywood slated for this afternoon. Both sets of panels, first and second floors, both exterior and interior walls are stacked and prepared to be erected. This crew is full time employed by Babb Custom Homes understanding the required speed and possessing the experience to benefit from what prefabricated components can add to the construction process. Interesting to note is the center bearing post of the garage being shipped loose so the LVL garage door headers can be set in the notched openings on either side. What transpires onsite is the cultimation of hours of planning and design, with approval modifications, integrating structural and architectural specifications into a cohesive component unit. All that is left is to fit the puzzle pieces together.

Charleston Landing 144

July 24th, 2012

Today, a new component home has started in the Charleston Landing, a Little River subdevelopment. Most homes in this area are built off a concrete slab so using a floor truss system hanging from flush LVL’s is a welcomed change from the norm. The LVL girder system sits on piers spaced 8′-0″ apart and the floor trusses interior bearings are cradled in hangers nailed into the girders. LVL’s are engineered, microwaved composite beams which can be empircally verified for the loads they assume. Often these beams are made from particles of low density lumber making them the right choice ecologically. In comparison to 2×12′s dimensional lumber, their counterpart in the girder marketplace, they are certainly straighter and maintain a uniformed height more effectively. This laminated veneered lumber is the workhorse of the component home. With the onset of increased awareness of seismic reactions relating to home construction, many structural engineers specify rimboard on the exterior walls. This practice assures proper vertical force load transference to the foundation. Tomorrow, the floor system will be sheathed with 3/4″ T+G plywood before the 1st floor walls can be set into place. Both the first and second floors were shipped together Monday to be followed by the second floor walls along with the upper and lower roof trusses arriving Wednesday. What develops from this tight knit scheduling is all materials are available before they are actually needed. The key is delivery JUST before they are needed, eliminating downtime waiting for materials to arrive. Scheduling delivery is cultimation of drawings and layouts being reviewed and approved weeks ahead of the target date. In all honesty, the actual production and delivery of the components falls into a 5 to 7 day window. Most of the design and approval processes take multiple weeks to accomplish. I would guess the phrase “measure twice and cut once” is applicable here. Rarely in residential wood construction is a house built exactly per plan. Uncovering the caveats and nuiances of each plan, each homeowners preferences, creates the challenge encountered by the component sales and design team. Component construction full proofs this challenge by accounting for how each and every component is used, installed, and interacts with one other.
