Install Footings As the location and load for each support is determined, note it on the sketch. When select- ing locations for supports. keep in mind that increasing the spacing between supports will increase the load on that support and the size of the required footing DETERMINE LOCATIONS Point loads exist where a bearing/structural weight is concentrated and transferred to the foundation at a specific point. Locate a support under each point load, including the follow- ing examples. • Exterior doors in side walls at both sides of each door(blocking is not required at exterior doors in end walls supported by the steel header) • Other exterior wall openings four feet and greater at both sides of each opening (including multiple windows that total four feet wide or more without intermediate supports. even If individual windows are less than four feet). • Marriage line openings four feet or greater at both sides of each opening. • Locations where through-the-rim crossover ducts penetrate the rim joist at the mar- riage line(unless otherwise noted in supplemental documents provided with the home or unless the home is constructed with a perimeter frame system). • Marriage line columns. • Load-bearing porch posts. • On each side of factory installed fireplaces when located on the exterior sidewalls or marriage walls(except when supported by the steel header). Adjustable outriggers may only oe used to replace piers below exterior door or window open- ings less than 48"and below factory installed fireplaces located on the exterior sidewalls or marriage walls. Adjustable outriggers may only be used at these locations when local codes permit the use of these devices and they are installed according to the manufacturer's instal- lation instructions. Adjustable outriggers are not an acceptable replacement for perimeter supports on homes requiring perimeter blocking Factory installed outriggers and cross- members may also replace piers below exterior door or window openings less than 48". Mark the required point load support locations on the sketch. Supports are not required where the manufacturer has reinforced the floor(such as with additional outriggers or floor joists)and so noted in the documentation provided with the home.

For each support, find the table with the appropriate section width Then, find the row with the appropriate roof load zone and the column corresponding to the span(see Figure 7 for guidance on determining spans—if a support is shared by spans on both sides. add the respective loads together to arrive at the total load under that paint) The number in the intersecting cell is the load. Nate the required loads next to each point load support on the sketch. I
