Install Footings <br /> Install Footings <br /> This chapter provides instructions for the design and construction of individual footings that transfer the load from a single pier <br /> to the ground.A footing and pier together(discussed in Set the Home)is referred to as a"support".A footing may also be de- <br /> signed to carry the load of multiple piers(often called"strip"footings), The design of strip footings is not covered in this manual. <br /> However, strip footings are acceptable if designed by a registered engineer or registered architect. The foundation systems <br /> described in this manual have not been designed for flood resistance. <br /> Follow the Steps below: <br /> T STEP 1.

DESIGN POINT LOAD SUPPORTS <br /> All homes will need supports,and therefore footings,under the frame, marriage line(for <br /> multi-section homes), exterior wall openings and other heavy point loads. <br /> All pier locations required at the mating line, perimeter and any special pier support locations, <br /> as required by these instructions.will be identified from the factory by a pier tag,label, paint, <br /> or other means and must be visible after the home is installed. The pier designs,support <br /> loads, and footing construction shall be as indicated in the appropriate diagrams,tables, and <br /> instructions herein.Where perimeter piers are required along the exterior wall,alternate pier <br /> spacing may be used in lieu of the factory identified locations provided the instructions of this <br /> manual are satisfied in terms of allowable spacing, pier design, and footing size. <br /> PLEASE NOTE:The manufacturer will not be responsible for damaged or removed pier tags. <br /> It is the responsibility of the installer to ensure that all piers are properly positioned in accord- <br /> ance with the tables&diagrams contained in these installation instructions. <br /> Create a sketch of the home that includes the exterior walls,the frame I-beams and the <br /> marriage line(s), if a multi-section home.The sketch will be used in this chapter to locate <br /> each support,and note the size of the corresponding footing. Figure 6 is an example of <br /> such a completed support plan. <br /> PERIMETER 4 DOOR PIERS <br /> BLOCKING PIERS -, <br /> r t • <br /> I-BEAM FRAME <br /> MEMBERS Figure 6.
