### Onsite construction assembly procedures

Straight, right-angle and switch-back layouts are shown.
For illustrative purposes, a 58" x 7'11" level landing is shown at the doorway. The first sloped section is the same on all three ramps (much of the construction for all three styles is identical). All ramps have twenty-nine feet of sloped surface and could be made with 58" length modules, combinations of 116" and 58" modules.

The design of the level landing at the doorway is critical to the functional use and construction of the ramp. Because of the wide variety of existing stoops and entry-way configurations, it is not possible to design a modular component that will meet the needs of all entry ways. Usually construction of the level landing requires customization on-site. Keep in mind the space requirements for use of the doorway and the requirements of the other users of the doorway (see page 8). Steps will often need to be built to the new landing to replace the old steps covered. Steps are probably the hardest component to build. Experienced builders should handle that task. Before beginning construction, be sure to review the design principles listed in this manual as a final check. It is easier to change the design before construction than after construction.

Place landing module so that 2x6 joists are 1 3/4" below bottom of door (when decking is added you will have 1/2" door clearance). Insure that the landing is level (temporary support with bumper jacks is helpful in leveling landing). Place pads as shown in drawing then measure from top of landing including decking to each pad. Add 34" to this measurement and cut 4x4's to this length. Attach pads to 4x4's with screws and place in position, insure they are plumb. Attach cross supports with screws temporarily. Be sure cross supports fit snuggly under landing and that landing is level. |
