104.02 Use of Roads by Contractor. Add the following:

Maintenance requirements for roads that are to be constructed or reconstructed as part of this contract apply only after the roads have been completed and accepted. For other roads, prehaul maintenance may be required before use begins. Other maintenance requirements also apply when Contractor's use of roads begins.

Maintenance required, and applicable maintenance specifications, are shown in the

Road Listing. Perform maintenance in accordance with the Standard

Maintenance Specifications as published in the Forest Service Handbook

-Transportation System Maintenance Handbook in effect on the date of advertisement.

These maintenance specifications are available from the local Forest Supervisor's office. Special Project Specifications shown in the Road Listing supersede or clarify standard maintenance specifications and are attached hereto.

ROAD LISTING:

Maintenance Requirements

811 = Blading

106.03 Units of Measurement

Delete this subsection and add the following:

“Forest Service Specifications for Construction of Roads and Bridges (Revised August 1996) are based on Modern Metric units of measurement. The dimensions and units of measure SHOWN ON THE DRAWINGS for this contract utilize U.S. Standard English units of measure. The SPECIAL PROJECT SPECIFICATIONS developed for this contract, utilize dual units of both Modern Metric and U.S. Standard English units of measure. Convert all measurements referenced in the August 1996 Forest Service Standard Specifications (EM-7720-100) to U.S. Standard English units of measure. Appendix A – Engineering Conversion Factors and Appendix B – SI (Modern Metric) Conversion Factors, are included on pages 612 – 614 of the Standard Specification Appendices to assist with any required conversions.

Where references are made to a Metric technical specification, such as ASTM or AASHTO, use the equivalent U.S. Standard English technical specification for purposes of material certifications.

Work required by the contract will be paid based on the PAY UNIT (U.S. Standard English measure) as DESIGNATED IN THE SCHEDULE OF ITEMS.

Under each Specification Section with PAY ITEMS of work DESIGNATED IN THE SCHDULE OF ITEMS for measurement and payment under this contract, the last subsection “Payment - Basis”, shall have the following format:

Pay Item - Numbering system and work description to remain the same.

Pay Unit - Pay unit(s) DESIGNATED IN THE SCHEDULE OF ITEM have been changed from metric to the corresponding unit of U.S. Standard English measure.

Payment will be by units defined and determined according to U.S. Standard English measure and by the following:

(a) Cubic Yard in Place. Measure solid volumes by the average end area method as follows:

(1) Measure cross sections of the original ground and use with design or staked templates, or take other comparable measurements to determine the end area. Do not measure work outside of the established lines or slopes.

(2) If any portion of the work is acceptable, but is not completed to the established lines and slopes, re-measure cross sections or comparable measurements of that portion of the work. Deduct any quantity outside the designated or staked limits. Use these measurements to calculate new end areas.

(3) Compute the quantity using the average end areas multiplied by the horizontal distance along a centerline or reference line between the end areas. Deduct any quantity outside the designed or staked limits.

Where it is impractical to measure material by the average end area method, other approved methods involving three-dimensional measurements may be used.

Measure liquid volumes in accordance with SPS Subsection 106.03(h).

(b) Cubic Yard in the Hauling Vehicle. Measure the cubic yard volume in the hauling vehicle using three-dimensional measurements at the point of delivery. Use vehicles bearing a legible identification mark with the body shaped so the actual contents may be readily and accurately determined. Before use, mutually agree in writing upon the volume of material to be hauled by each vehicle. Vehicles carrying less than the agreed volume may be rejected or accepted at the reduced volume.

Level selected loads. If leveling reveals that the vehicle was hauling less than the approved volume, reduce the quantity of all material received since the last leveled load by the same ratio as the ratio of the current leveled load volume to the agreed volume. Payment will not be made for material in excess of the agreed volume.

Material measured in the hauling vehicle may be weighed and converted to cubic yards for payment purpose if the conversion factors are mutually agreed to in writing.

Compute measurement using measurements of material in the hauling vehicles at the point of delivery. Load vehicles to at least their water-level capacity. Leveling of the loads may be required when vehicles arrive at the delivery point.

(c) Cubic Yard Mile. A combination of linear and volumetric measurement meaning the movement of a cubic yard of material one(1) mile.

(d) Hour. Measurement will be for the actual number of hours ordered and performed by the Contractor.

(e) Each. One complete unit, which may consist of one or more parts.

(f) Lump Sum. Do not measure directly. The bid amount is complete payment for all work described in the contract and necessary to complete the work for that item.

(g) MFBM. One thousand feet board measure based on nominal widths, thickness, and extreme usable length of each piece of lumber or timber actually incorporated in the job. For glued laminate timber, 1,000 board feet based on actual width, thickness, and length of each piece actually incorporated in the job.

(h) Gallon. The quantity may be measured by any of the following methods:

a. Measured volume container.

b. Metered volume. Use an approved metering system.

c. Commercially packaged volumes.

(i) Station. One hundred linear feet measured horizontally.

(j) Station Yard. A combination of linear and volumetric measurement meaning the movement of a cubic yard of material one station.

(k) Square Yard. Measure on a plane parallel to the surface being measure or horizontal.

(l) Thousand Gallons Mile. A combination of linear and volumetric measurement meaning the movement of 1,000 gallons of material one (1) mile.

(m) Ton. Short ton consisting of 2,000 pounds. Use net certified scale weights based on certified volumes.

(n) Ton Mile. A combination of linear and weight measurement meaning the movement of one (1) ton of material one (1) mile.”

633.02 Traffic Control Sign Details. Add the following:

American Recovery and Reinvestment Act (ARRA) Sign. Ensure that ARRA signing meets the requirements of the MUTCD and the “Project Funding Source Sign Assembly” details that are attached including sign layout and color. Comply with the requirements of the “FOR USE ON LOW SPEED ROADS OR NON-ROAD PROJECTS” sign. With respect to placement of signs, regulatory, warning, and guide signs have a higher priority than economic recovery signs. Economic recovery signs shall not be placed where they can obscure road users’ view of other traffic control devices. Economic recovery signs should be placed where they can be easily identified with the corresponding project(s). If the placement of an economic recovery sign conflicts with newly installed higher priority signs, traffic signals, temporary traffic control devices, or other priority devices, the economic recovery sign should be relocated. Due to public safety concerns, economic recovery signs should not be allowed at the following locations:

· On the front, back, adjacent to, or around any traffic control device, including traffic signs, signals, changeable message signs, traffic control device posts or structures, or bridge piers

· At key decision points where a driver’s attention is more appropriately focused on traffic control devices, roadway geometry, or traffic conditions. These locations include, but are not limited to, exit and entrance ramps, intersections controlled by traffic signals or by stop or yield signs, highway-rail grade crossings, and areas of limited sight distiance.

SECTION II

Road Maintenance Specifications

*Note: All road maintenance requirements shall be considered incidental to construction work.

811 BLADING (2/02)

811.01 Description

This work consists of surface blading the traveled way to a condition to facilitate traffic and provide proper drainage. Blading includes shaping the crown or slope of traveled way, berms, and drainage dips in accordance with this specification. Compaction is required when shown on the road listing.

811.02 Maintenance Requirements

A. Timing- Perform surface blading during the contract period as ordered by the Government. Commence surface blading within two (2) contract days after receipt of written order unless otherwise stated in the order.

B. General-

1. Blade and shape the existing traveled way and shoulders, including turnouts unless otherwise ordered, to produce a surface which is uniform, consistent to grade, and crowned or cross-sloped as indicated by the character of the existing surface, unless otherwise shown in the Road Listing, to at least 13 mm (½ inch) per .305 meter (1 foot) of width, but not more than 19 mm (¾ inch) per .305 meter (1 foot) of width. Thoroughly loosen surfacing material to no less than 50 mm (2 inches) depth or the depth of potholes or corrugations. Scarification to facilitate cutting to the full depth of potholes or corrugations may be elected, but will be considered incidental to blading. Do not scarify deep enough to cause contamination of the surfacing.

2. When Section 891 is included in the Road Listing, apply water during blading when sufficient moisture is not present to prevent segregation. Water supply, hauling, and application shall be in accordance with Section 891 and are incidental to blading unless Pay Items for Section 891 are designated in the SCHEDULE OF ITEMS.

3. Shape existing native rock or aggregate surfaced drainage dips to divert surface runoff to existing outlet devices, ditches, and discharge locations.

4. Establish a blading pattern which provides a uniform driving surface, retains the surfacing on the roadbed, and provides a thorough mixing of the materials within the completed surface width. Upon final blading, no disturbed rock shall protrude more than 50 mm (2 inches) above the adjacent surface unless otherwise provided in the contract. Remove and place outside the roadbed material not meeting this dimension so as not to obstruct drainageways or structures. This material may be scattered off the roadbed if there is free drainage.

C. Routine Blading

1. Conform to the dimensions SHOWN ON THE DRAWINGS or designated in the SPECIAL PROJECT SPECIFICATIONS upon completion of blading.

2. Shape roadbed width in excess of the dimensions shown only as needed to provide drainage away from the traveled way. Do not remove established grasses and other vegetation from the excess width except as incidental to providing drainage or unless otherwise provided in the contract.

D. Compaction- Roads requiring compaction will be included in the Road Listing. Unless Compaction Method B is designated in the SCHEDULE OF ITEMS and Road Listing, all traveled ways requiring compaction shall be compacted by Method A. Compaction shall commence immediately following blading. Compaction methods are:

Compaction Method A: By breaking track while operating equipment on the traveled way.

Compaction Method B: 7-9 (7-10 ton) metric ton pneumatic, steel, or equivalent vibratory roller, operated to cover the full width two (2) times.

E. Intrusions- Where the minimum width SHOWN ON THE DRAWINGS or included in the SPECIAL PROJECT SPECIFICATIONS is not available, the Contractor will construct berms where ordered and marked on the ground. Material to provide berms will come from sources SHOWN ON THE DRAWING or designated in the SPECIAL PROJECT SPECIFICATIONS.

F. Undercutting- Undercutting roadway back slope is not permitted.

G. Intersections

1. At intersections, blade the roadbeds of side roads which are not closed or restricted from vehicular use to ensure smooth transitions.

2. Signing, cross ditching in the road surface (traveled way), earth berms, or other devices placed to discourage or eliminate use by passenger cars, are field evidence of road closure or restriction. Roads listed for work under Sections 835 or 838 are considered restricted.

3. Side roads listed for work under this Section are not restricted.

H. Cleaning of Structures- Do not allow materials resulting from work under this Section to remain on or in structures, such as bridges, culverts, cattle guards, or drainage dips.

I. Berms- Maintain existing berms to the condition of adjacent segments when ordered by the Government.

J. Smooth blading- Smooth blading may be used as an interim measure to remove loose surfacing material from the wheel paths and store it in a recoverable windrow until blade processing, as described in this section, is feasible. Watering will not be required for smooth blading. Accomplish smooth blading without distorting the existing cross-slope or crown of the traveled way.

Move and store loose surfacing materials on the high side of super-elevated curves and sections with uniform inslope or outslope. In crowned sections, store the material on either or both sides as elected. Windrow and place stored materials to provide not less than 3.6 meters (12 feet) of smooth traveled way on one-lane segments, or 6 meters (20 feet) of smooth traveled way on two-lane segments, or segments with turnouts. Cut holes through windrows, which may collect water on the road, for drainage at least every 150 meters (500 feet).
