• 2/1/10 This document describes a change to the bridge and deck project. Originally, the design called for 6x12 beams to form the outer supports of the bridge. However, availability of processed material in the 6x12 size has proven to be problematic. The proposed solution is to use 6x12 glulams (actual size 5.125 x 11.5) instead. All other aspcts of the project remain the same. The glulam type is identified as Western Wood Structures 24F -V4 grade coastal region Douglas Fir. The glulams will be pressure treated according to AWPA P8 and P9 (copper napthenate and mineral spirits) to at least UC4A levels. The strength factors for the glulams are Factor Unadjusted value Derated for Derated for env & life • environment Fb 2400 PSI 1920 1728 F'b 1641 MOE 1.8x10 1.5x10 1.5x10 Fv 265 PSI 232 209 Fe 1 650 PSI 345 310 Fc 1650 PSI 1205 1085 EVISION PNE 7C) iAkFp City of Tigard FEB 0.4 201 Ap • rove • Plans By i►:.i Date � f l / 10 -. _ Bk.110$6 I3 7f 7 - 0027 OFFICE COPY lit 5 I-1bW I NG DECK.

BUILDING DIVISION Tigard, Oregon 97224 The dwelling at this address was constructed about 28 years ago and some of the materials used in the deck and footbridge have deteriorated with age and weather so that replacement is now required. This project will attempt to nearly replicate the original design, both aesthetically and structurally but changes will be made to comply with the current building codes. The house is built on a steep slope and this makes the front porch (which is near street elevation) about nine feet above the ground. Consequently, a wooden foot bridge extends from the driveway to the front door for human convenience. The front of the house also attaches to a deck which runs the entire length of the house, plus a little. Aside from the deterioration due to weather, the deck and footbridge have been satisfactory as originally designed and built so the original design intent will be preserved. Some portions of the nrigjnal wor]s will be retained; These include the concrete pads which support the deck and footbridge, the concrete pads which abut the end of the bridge and the bottom of the stairs, and most of the ledger hoards which support the deck. Also, the house was retrofitted with natural gas in 1996 and the gas pipe is supported by the same joists which support the deck. The gas pipe will be accommodated by the replacement structure. The drawings which form a portion of this package are done approximately to scale, as noted on each sheet. GENERAL NOTES 1. All lengths shown in drawings are in inches. 2. With the exception of the bolts which secure post bases to their mounting brackets, all fasteners re stainless steel (SS). This is due to the corrosive nature of the presently available pressure treated wood. The post base fasteners are glvanize4 because they mate with galvani d bra ts. 3. All new wood is,KDAI and is rated for ground contact even though none of it actually contacts the ground. This provides better longevity. 4 ry # Kt a L I ql • 4. All wood cuts, holes, notches, etc. will be treated with end cut solution. ° tA. 5. Joist boards are a Idea grade of 2x6. This provides better strength and stiffness than usual. fa • f 6. The new deck planks will be TimberTech 2x6 comuosite banks. This material is low maintenance and provides better fire resistance than wood. 7. Deck planks will be fastened with #10 x 3" stainless steel deck screws, 8. The orientation of the deck planks will alternate between N -S and E -W. The original design used all N -S orientation but this produces a potential problem with thermal expansion because each board's expansion adds to that of the other boards. The alternating orientation provides small expansion gaps between each section so that not more than about 12 feet of board is involved in dimensional shift with temperature. Also, the alternating orientation provides a pleasing visual effect. 9. The term "crossbox" will be used in this document to indicate a region where the deck planks run perpendicular to the house, as opposed to the usual parallel orientation. 10. The gck varies in height above ground from about 4 feet 1,0 abouteez. 11. The bridge varies in height above ground from about 1 oot to about 9 feet, SPECIFIC NOTES 1. Where joists interfere with the gas pipe, the joists will be notched to clear the pipe. This is necessary because some of the new joists will be a little wider than the original joists. Se__ �� R50a. • 2. In some places, the ends of TimberTech planks will be visible (for example, both ends of each bridge plank). Where such ends are visible, TimberTech end covers will be used. 3. All joist hangers are stainless steel, Simpson LUS26SS. 4. Stainless steel right angle connectors will be used at the four corners of the deck, Simpson A35SS. 5. All nails are stainless steel joist hanger type. Their diameter is .148 inches. The length is either 1.5 inches or 3 inches, as appropriate. In a few places, where the 1.5 inch nails might bulge the wood on the far side and create a visible scar, 1/16 inch stainless steel washers will be used under the nail heads. 6. The ledger board attached to the house contains more than 130 nails attaching it to the house. 7. The ledger board attached to the garage contains more than 52 nails attaching it to the garage. 8. Because of the corrosive nature of the pressure treated wood, Vycor Deck Protector barrier material will be used to separate dissimilar metals such as the aluminum downspouts from the copper compounds in the wood. 9. (DOWNSPOUT NOTE) The house has three downspouts which penetrate the deck. These require Vycor covering of the adjacent ledger, joist, or block. The downspouts also require that a block be installed between the two nearest joists to provide support for the deck plank which is notched to clear the downspout. 10. POST 1 is a 4x6 of 122 %z inches length down to a concrete pad. 11. POST 2 is a 6x6 of 57 'A inches length down to a concrete pad. 12. POST 3 is a 6x8 of 44 inches length down to a concrete pad. 13. POST 4 is a 4x6 of 15 '/2 inches length down to a concrete pad. w • 4 . • I 14. POST 5 is a 4x6 of 11 '/2 inches length down to a concrete pad. 15. The concrete pads for posts 1 -3 are at least 24 inches diameter and 42 inches deep. 16. The concrete pads for posts 4 -5 are at least 12 inches diameter and 42 inches deep. These pads carry only a small load because the 6x12 beams pass over them and are supported by other posts about 2 feet away. 17. The bridge is supported by a double joist sysrem. The upper joists, which support the planks, run longitudinally with the bridge and are supported at the ends as well as by the second set of joists. The second set of joists run crossways to the bridge, fasten to the beams which support the bridge, and support the upper joists. The drawing shows the lower joists as solid lines while the upper joists are shown as dashed lines. 18. Crossboxes will contain short joists (which could be considered to be blocks) spaced at not more than 24 inches, the maximum allowable spacing for the TimberTech plank supports. Each crossbox is also 24 Vs inches wide because it needs to accommodate four 2x6 planks with a small gap between each. Also, at least one end of the crossbox will need a special ' joist" which clears the joist hangers next to it. See the "T joist" drawing. 19. Expansion gaps will be provided around the perimeter of each deck plank. Generally, these are 1/8 inch but at the locations where long planks meet crossboxes the gap is 3/16 inch. 20. The deck joists are situated 1.5 inches lower than the top of the ledger boards. This makes the deck plank tops level with the tops of the ledger boards. 21. The tops of the 4x10s are level with the joist tops. This allows the deck planks to cover the 4x 10s. 22. The frontmost deck plank will have water drainage notches cut into its bottom surface every 6 inches. The provide a path for water to escape from the gap between the first two deck boards. This water would otherwise be trapped by the 4x10 below the gap. 23. All tops of joists and beams will be covered with Vycor. This is to help prolong the life of the wood by keeping it mostly dry. 24. The bridge height is 5.5 inches below the deck level. 25. The bridge is height is 7 inches above the level of the concrete pad at its west end. 26. The deck and bridge will be edged with a custom made railing from Railingworks, their fascia mount model with 2" rails and a height of 42 inches. 27. The south end of the deck will have a stairway descending 37 inches down to a concrete pad. Step heights are 7.4 inches and step widths are 11 1/8 inches. 28. Some deck planks will have pointed ends due to the angle of the garage wall. These ends will be supported by stainless steel right angle brackets mounted to the ledger board. . � � - -____ r i F i !___ . A_ __, . ,._ . E.
