(a) Removal of Bridge Wood Decking. Remove existing wood decking as indicated on the Drawings and as required in the following paragraphs. Coordinate the work of this section with bridge replacement work.

Saw cut or flame cut the existing shear connector, if any, between timber purlins and steel beams. While doing so, care should be exercised not to induce any damage to the steel beams.

Remove existing cover plates at the bottom of the side-beams by removing the existing weldments using appropriate technique without inducing any damage to the steel beam flange. After removing the cover plates, grind the bottom surface of side-beams to remove unevenness.

Remove a block of concrete from each existing support point for side-beam at the abutments. Purpose of these cut-outs is to lower the bearing seat elevation of side-beams at abutments by 10 1/8”. Therefore, each cut-out should be 10 1/8” high, 16” wide with its back face aligned with the existing inside vertical surface of the end wall. Ends of exposed rebars, if any, shall be plugged by suitable epoxy.

Furnish timely notification of demolition work to USDA Forest Service. Prepare a Demolition Plan if required by the CO. Before beginning demolition activities, examine the Site and Drawings to determine the extent of the demolition work to be performed.

Take necessary precautions to avoid damage to existing structures to remain in place (abutments, bent pedestals, bent columns, and structural steel). Construct and maintain shoring, bracing and supports as required according to Section 562. Repair or replace damaged structures as approved by the CO.

Provide protective measures, such as tarpaulins or other devices under decking, to prevent demolition debris from falling into the creek and other adjacent areas. If debris does accumulate, provide acceptable measures for removal.

Remove existing wood decking to top of existing structural steel. Remove wood decking in a systematic manner using tools, equipment and methods acceptable to the CO. Locate demolition equipment throughout structure and remove materials so as not to impose excessive loads to existing structures to remain.

Recycle or dispose of removed wood decking and dispose of demolition debris accordingSubsection 203.05(a).

203.05_nat_us_02_18_2005

203.05 Disposing of Material.

Add the following:

(e) Windrowing Construction Slash. Place construction slash outside the roadway in neat, compacted windrows approximately parallel to and along the toeline of embankment slopes. Do not permit the top of the windrows to extend above subgrade.

Use construction equipment to matt down all material in a windrow to form a compact and uniform pile. Construct breaks of at least 15 feet at least every 200 feet in a windrow.

Do not place windrows against trees. Obtain approval for pioneer roads. A pioneer road may be constructed to provide an area for placement of windrows, provided the excavated material is kept within the clearing limits and does not adversely affect the road construction.

(f) Scattering. Scatter construction slash outside the clearing limits without damaging trees. Limb all logs. Place logs and stumps away from trees, positioned so they will not roll, and are not on top of one another. Limb and scatter other construction slash to reduce slash concentrations.

(g) Chipping or Grinding. Use an approved chipping machine to grind slash and stumps greater than 3 inches in diameter and longer than 3 feet. Deposit chips or ground woody material on embankment slopes or outside the roadway to a loose depth less than 6 inches. Minor amounts of chips or ground woody material may be permitted within the roadway if they are thoroughly mixed with soil and do not form a layer.

(h) Debris Mat. Use tree limbs, tops, cull logs, split stumps, wood chunks, and other debris to form a mat upon which construction equipment is operated. Place stumps upside down and blend stumps into the mat.

(i) Decking Firewood Material. Remove brush from decks. Limb and deck logs that do not meet Utilization Standards according to Subsection 201.04 as directed by the CO. Cut logs to lengths less than 30 feet. Ensure that logs stacks are stable and free of brush and soil.

(j) Removal to designated locations. Remove construction slash to designated locations.

(k) Piling. Pile construction slash in designated areas. Place and construct piles so that if the piles are burned, the burning will not damage remaining trees. Keep piles free of dirt from stumps. Cut unmerchantable logs into lengths of less than 20 feet.

(l) Placing Slash on Embankment Slopes. Place construction slash on completed embankment slopes to reduce soil erosion. Place construction slash as flat as practicable on the completed slope. Do not place slash closer than 2 feet below subgrade. Priority for use of available slash is for: (1) through fills; (2) insides of curves; and (3) ditch relief outlets.

(m) Hydrological Sensitive Placement. Where required use this method in combination with other designated methods to dispose of material to reduce erosion and to aid in re-vegetation:

1. Place windrow segments on contours, wrap in type I geotextile.

2. Place logs as log erosion barriers on contours. Place logs so that 80% of their length is on the ground surface.

3. Scatter slash on bare or disturbed areas within or outside the clearing limits as directed.

4. Scatter chips or ground woody material on bare or disturbed areas within or outside the clearing limits as directed.

Place stumps in swales or on sites to form planting pockets. Place windrow segments on contours, wrap in type I geotextile.

203.05_nat_us_02_24_2005

203.05 Disposing of Material.

Add the following:

(e): Scattering. Scatter pieces of wood less than 3 inches in diameter and 3 feet in length within the clearing limits. Do not place construction slash in lakes, meadows, streams, or streambeds. Immediately remove construction slash that interferes with drainage structures.

For compaction according to method (a), (b), or (c), use AASHTO T 27 to determine the amount of material retained on a Number. 4 sieve. For compaction methods (d) or (e) no sieve test is required.

Add the following compaction methods:

(d) Layer Placement Method (Hauling and Spreading Equipment). Place material by end dumping to the minimum depth needed for operation of spreading equipment. Level and smooth each embankment layer before placing the next layers. Operate hauling and spreading equipment uniformly over the full width of each layer. Construct a solid embankment with adequate compaction by working smaller rock and fines in with the larger rocks to fill the voids, and by operating hauling and spreading equipment uniformly over the full width of each layer as the embankment is constructed.

(e) Layer Placement (Roller Compaction) Method. Place material by end dumping to the minimum depth needed for operation of spreading equipment. Adjust the moisture content of the material to obtain a mass that will not visibly deflect under the load of the hauling and spreading equipment. Operate compaction equipment over the full width of each layer until visible deformation of the layer ceases or, in when a sheepsfoot roller is used, the roller “walks out” of the layer. Make at least three complete passes.
