Materials:
The materials are listed in the Excel spreadsheet attached here:
Notes:
- All wood is pressure treated, AC2, arsenic-free.
- Ramp has a 1 inch drop per foot of length.
- Deck at door is 4½’ x 6’ instead of 5’ x 5’ to allow ramp to fit on existing concrete pad.
- Existing metal steps and porch are to be removed. It may be possible to re-build those metal steps to provide step access to the street side of the deck at the doorway. In such case, a re-design of the rail for that deck would be needed. The code governing such a design has not been investigated, and it has been assumed that the existing steps will be discarded.
- 4 x 4 posts, except as noted on the drawings, are set on the concrete pad without attachment. One post is attached to the concrete pad with anchors, and five posts are supported by concrete piers set on the soil. No posts are set into holes in the ground.
- Estimated costs are based on prices at Menards in August, 2004. “Normal” prices are used in all calculations. Where materials were “on sale” at Menards in August, the sale price is shown in the comments.
- Approximately 37 feet of ramp framing, 2 4x4 posts, 146 rail spindles, 1,200 deck screws, 112 linear feet of 2 x 4s, and 473 linear feet of deck boards are material re-used from the deck removed from the Willingham residence in Marion. This will use most of the deck boards and all of the 2 x 4s.
- Spindles are used between the railing and toe board on the two decks and the upper ramp section, to provide an enclosed railing for all parts of the ramp higher than 30” off the ground.
- Spindles are not called out for the railing of the lower ramp section. They are not required. However, they could be installed on the front rail for aesthetic purposes, if desired. It would require about 55 additional spindles, which are available from the salvaged material.
- The rail spindles in this design are 35” tall. 7” will need to be cut off from each of the salvaged spindles.
- Skirting for the ramp and decks was not identified or included in the cost estimate. It is assumed that the same material that was used around the home will be used.
- Costs to deliver materials are not included, and are expected to be about $35 per trip.
- Undercoat and Paint have been included in the cost estimate. To meet code requirements, silica sand should be added to the paint so the ramp will not be slippery when wet.
