Tucked away off 6th Ave S and Waterway Drive in North Myrtle Beach is Babb Custom Homes latest component construction home. Consisting of three levels, this piling house has a beautiful view of the Intercoastal Waterway and has been under construction for a little over one week. All of the walls past the first level have been set in place with a crane and shuffled to their respective positions Much of the anchorage hardware, necessary bracing and blocking is handle on the level as they move upwards. The use of wall panels aids in the completion of these items as the level is already basically framed and the permanent fastening requirements can be addressed earlier in the construction process. The second level floor system was to be set and sheathed before the third level wall system arrived to be craned into position. The roof system is scheduled to be delivered on Wednesday the 23rd to allow for several days of deck assemblies. As in most large multi-leveled coastal homes, a combination of steel I beams with deep LVL’s are integral in transference of the load paths generated through both point and uniformed loads. Structural sealed drawings are adhered to in the design of the wall panels and trusses, allowing for the proper strapping as required by code. Babb Custom Homes realizes the benefits yielded by component construction’s review process prior to problems occurring in the field.

The progress on setting the roof system on the 100 Club Drive job site is nothing less than remarkable in my humble opinion. IG Construction crew members, shown here, have a right to be proud of their achievements up to this point. The main roof trusses along with the garage trusses are erected, as the “piggy-back” upper roofs are being swung into place atop the purlins prepared for them. To handle and brace these large span trusses is difficult and dangerous. Their experience was clearly evident as they moved nearly effortless on the top plates, each conducting their individual roles. The left side hip was being nailed as the sunset sunk into the ocean across the street, taking with it all ambient lighting for the work site. The form and the shape of the building is defined by the intricate roof pieces being assembled into place. Nestled between the great room, sitting and kitchen areas walls are columns designed to carry the timber trusses observable from below making this home unique in more ways than one.
Hit hard by the flu bug and relegated to bed for the last two days, I still managed to get to the Dunes Club to handle issues, at least Monday morning that is. The opportunity to go into the structure and take some photos yielded these pictures of the variety of plate heights present on the job. Ranging from 10′-0″ to 18′-0″ tall, the angled walls on either side of the great room were the most striking. This afternoon, the general contractor sent me the one where trusses were set over the same area, a “little house he was building in the Dunes Club” he called it. Thought it was fitting showing the massive great room walls capped with the vaulted ceiling that will house the exposed timber trusses below them. Actually, as mentioned in the previous post, nearly the same amount of trusses started shipping today to occupy the same area vacated by what was set. The wall panels using the Framers Series lumber were erected without much of a hitch. Not the same result for the roof trusses though, as three problems arose leading to creative problem solving. I am fortunate to have a design staff and an insightful general contractor to review the situation and choose the correct course of action to solve them. One of them involved the 4 ply girder bearing height. You can imagine the amount of materials and labor it takes to screw, bolt and arrange the hangers prior to setting it. Being able to use it and stay on schedule, finding the most advantageous solution, was probably the most significant single decision of the whole project thus far.
Any question I had regarding breaking the main roof trusses into two orders was cast aside upon arriving at the job site for 100 Club Drive this morning. What is shown here is “Part 1″ consisting of four individual truckloads. After the rain subsides, the crane is due to begin setting this massive amount of trusses, creating room for “Part 2″ scheduled for Wednesday of next week. The interior wood wall panels are completely set, of which I didn’t even enter the structure to take pictures as I marveled at roof deliveries in front. “Part 2″ is almost as large of a shipment as what you see here so the framing crew has their work cut out for them preparing for it. Literally there is no room for any materials left until “Part 1″ is set into place. Besides consuming all storage area in the front, there are trusses clear spanning over 66 feet long in these stacks. Special lifting and bracing details are required in handling trusses this large. Of special interest are the trusses over the great room, designed 12″ o/c and doubled. This section envelops the true Douglas Fir timbers below, stubbed around the masonry fireplace as necessary. The wall panels in the great room were engineered to carry the huge point loads via parallam columns. Although the roof trusses above will carry the roof and ceiling loads, these timber trusses spaced 8′-0″ o/c are extremely heavy, generating their own forces needing a load path to the foundation. All these factors were prepared for in advance through the coordination of timber engineering firm working in unison with the truss and wall panel designers to assure success.
