The entire exterior of each of our homes is sheathed in Zip System structural sheathing in order to resist the lateral loads from earthquakes and to provide the water-resistive barrier. Although longer lengths are available, I order 8-ft. sheets for better unit pricing and to minimize waste due to odd floor sizes, such as 14-in. While platform framing is generally faster and safer, we find balloon framing is an efficient and safe way to build many of our tall walls—especially gable-end walls (aka rake walls). has evolved over time into the process shown here, which incorporates the lessons we’ve learned along the way. To lower the jacks, do you have to raise/jack them all the way up off the 2x4, or are you able to lower, or ratchet them down? The jack looks a miniature stout pump jack and works on the same principle. The way we lift minimizes the force on the bottom plate; with a telehandler, we start by lifting up, then retract the boom a bit, and repeat until the wall is upright. OSHA Information Bulletin to alert employers and employees of potential risks associated with manually raising balloon framed walls. The 2016 FHB House is energy-smart, connected, healthy, and durable. You just brace the top of the posts to a nearby wall, rest the beam on the jack arm, and pump it up. As you lift the wall, the jacks creep higher on the 2×4 post to a point where they get beyond reach. from this stud height—it’s far easier to pad up if we have to than to plane it down. When floor framing gets attached to these tall walls, we hang joists off of ledgers that are attached to the wall using structural screws like FastenMaster FlatLok or Simpson Strong-Drive SDWS Timber screws. We hold the siding back 1 in. This Safety and Health Information Bulletin is not a standard or regulation, and it creates no new legal obligations. Later, when the wall is up, we can make minor adjustments if needed and add shims. So rather than calculate all the stud lengths for gable ends, I prefer to lay out the bottom plate, cut the top plates to the same length as the theoretical rafter length for this section of roof, and then use a story pole for the ends of the wall. To add another floor, they simply add another platform, then more walls. I wouldn’t recommend lifting these heavy walls without this training. After the wall is sheathed and nailed, we tape and roll the seams to ensure the tape adheres for an airtight and watertight assembly. It’s small and sensible. One framer measures along the bottom plate to the uphill side of all kings around openings, enters that as RUN in a construction calculator, punches in the roof PITCH, and just clicks the DIAG button to determine how far up the rake to mark. - M.K. sit the site of almost any new house going up in the United States, and chances are it’s being built using a method known as “platform framing.” Each story goes up independently, starting with a floor system that forms a so-called “platform.” The builders then frame and lift the first-story walls on top of that platform. I can confidently say that I expect to be a life-long subscriber." ), the roof pitch, and hit DIAG. Once all the openings are laid out, we cut and install an intermediate stud—one about halfway between the gable peak and the end of the wall. Then we square the window and fasten it with screws. Conduct "pre-lift" meetings to discuss the safest methods for raising these walls; Use a competent person to consider and supervise all aspects of the lifting operation; Use cranes with appropriate and approved attachments to assist in raising and placing balloon framed walls; Use either forklifts of adequate size and capacity for lifting balloon framed walls or rough terrain forklifts (Figure 1) with appropriate and approved attachments in placing balloon framed walls; Prior to the lifting of the wall, establish a limited access zone whenever a balloon framed wall is being raised; Secure bottom plates with adequate sized metal bands (at least a one-inch band nailed to the floor joists) located at each end of the wall and spaced not more than 6 feet apart (Figure 2) or other adequate feasible means of securing the bottom plate. After the walls are all up and the siding’s on, we install cornerboards over the siding to make these joints both durable and low maintenance. Learn the simple framing techniques that ensure accurately built, tightly framed walls. With the wall raised a little, the wall jack can be hooked beneath the top plate. I’ve found that pulling layout uphill and downhill from this stud minimizes any accumulated error, and by doing this on both sides of a gable it allows us to zero-out any error. With single-story gable walls, that simply means doubling the king studs on either side of openings. One is responsible for the majority of cutting and the other assembles the pieces. Pursuant to the Occupational Safety and Health Act , employers must comply with hazard-specific safety and health standards promulgated by OSHA or by a state with an OSHA-approved state plan. The wall jacks aren’t one-trick tools either; they can be used to lift a heavy beam. This cuts down the amount of time we have to spend on ladders, which reduces the chance of falls and the wear and tear on our bodies. If the house is clad in lap siding, we install that as well, because it’s easy to install and keep straight with the wall laid down. The sheathing ties everything together really well, and the bottom plate gets nailed 6 in. Our methods for building these tall walls. The Center for Construction Research and Training, Occupational Safety and Health Administration (OSHA), OSHA Guidance Document - Fall Protection in Residential Construction, Fatality Case Study, Multi-Employer, Residential Construction, Workplace Solutions: Preventing Injuries from Installing Drywall, How balloon framed walls can collapse onto the employees raising them; and. Even though it is plumb at the braces, we need to straighten it at the floor system. Once the wall is about two-thirds of the way up, Bruce and I usually finish lifting the wall with a light push rather than jacking the entire way. Employers can be cited for violating the General Duty Clause if there is a recognized hazard and they do not take reasonable steps to prevent or abate the hazard. Though I know math is perfect, I am not and neither is most lumber. Made of 3⁄8-in. We can frame and sheathe them flat on the ground, build overhangs and soffits, and even install siding and windows before lifting them into place. You’ll need stepladders to reach the jacks, especially when lifting tall walls. Sign up for eletters today and get the latest how-to from Fine Homebuilding, plus special offers. If the wall is two stories tall, we often drop the stud spacing down to 12 in. I order 16-ft. 2x6s for all wall plates—I haven’t found any advantage to switching to LSLs in order to keep them continuous on long walls.
