MIKE DOMBECK Chief FSH 2409.15 - TIMBER SALE ADMINISTRATION HANDBOOK WO AMENDMENT 2409.15-99-4 EFFECTIVE 04/01/1999 CHAPTER 50 - SPECIFIED TRANSPORTATION FACILITIES 50.4 - Responsibility. In addition to the responsibilities described in section 04 of this handbook, the following specific responsibilities apply to administration of transportation facility contract provisions. 50.41 - Contracting Officer. The Contracting Officer approves agreements with the purchaser for construction cost adjustments or delegates, in writing, the authority to the Forest Service Representative or the Engineering Representative, as indicated by the circumstances. 50.42 - Forest Service Representative. The Forest Service Representative approves estimates before crediting purchasers for specified road construction or reconstruction work, unless this authority is delegated to another member of the administration team. 50.43 - Sale Administrator. The Sale Administrator: 1. Works with the Engineering Representative in operations relating to timber harvest in right-of-way and specified road construction. 2. Administers assigned road maintenance responsibilities. 50.44 - Engineering Representative. The Engineering Representative has the following responsibilities for transportation facilities: 1. Administers the construction of specified roads, which includes: a. Documenting when a road is substantially complete. b. Advising the Contracting Officer on cost adjustments for differences between quantities of rock and culvert specified in contract and the actual measured quantities. c. Advising the Contracting Officer on design changes that reflect differences in anticipated and actual field conditions. d. Documenting any agreements that may be necessary during administration of the construction, and securing approval by purchaser and Contracting Officer as necessary, and approving those within delegated authority. 2. Coordinates activities with the Sale Administrator. These activities include: a. Approving use and hauling of right-of-way timber. b. Inspecting for compliance with fire precautions. c. Approving right-of-way slash disposal sites. d. Approving right-of-way landing sites. e. Calculating advance deposits (contract provision C(CT)4.221). f. Approving design changes. 50.5 - Definitions. The following terms and phrases are used in timber sale contract provisions related to roads: In Excess of Normal. Road maintenance caused by events that would not be considered part of the normal traffic or weather patterns. Specified Roads. Roads to be constructed or reconstructed and related transportation facilities and appurtenances, shown on the sale area map and listed in contract condition A(AT)9. Substantially Completed. 1. Completion of grading and installation of drainage structures so they function effectively, and 2. Placement of the specified depth of base course, unless physical conditions make it impractical or ground conditions permit hauling without undue damage. 51 - CONTRACT PROVISIONS FOR LOG SCALE AND TREE MEASUREMENT SALES. 51.1 - Authorization (B(BT)5.1). This contract provision authorizes the purchaser to construct, reconstruct, and maintain transportation facilities needed for harvesting included timber. This is only an authorization. It does not require construction of any road not needed for harvesting included timber. However, once construction of a specified road starts, the purchaser must complete the road to an agreed terminus (contract provision B(BT)5.2). The Contracting Officer may make an exception as a result of modification for catastrophe. This contract provision also authorizes the construction of temporary roads or facilities as needed and by agreement with the Forest Service Representative for the purpose of harvesting included timber. 51.11 - Requirements of Rights-of-Way (B(BT)5.11). FSM 5460 contains direction and policy on rights-of-way. The Sale Administrator must know and observe the stipulations of each easement or right-of-way document. If more rights are desired by the purchaser, they must be negotiated with the grantor. 51.12 - Use of Roads by Purchaser (B(BT)5.12). This contract provision establishes conditions for using existing roads in addition to specified roads listed in special condition A(AT)9. Justification, including environmental analysis, is necessary if the purchaser proposes use of a road where there is a need for road reconstruction or where the use is prohibited or restricted in the contract. Contract provision C(CT)5.12# identifies existing roads shown on the sale area map where use is prohibited or restricted. 51.13 - Specified Roads (B(BT)5.2). Specified roads are shown on the sale area map and listed in special condition A(AT)9. These roads are forest development roads. Do not authorize construction of a temporary road to avoid construction of a specified road. The purchaser must substantially complete construction of specified roads before timber hauling begins. If justified, the Forest Service Representative may relieve the purchaser, in writing, of this requirement. The term "substantially completed" is defined in contract provision B(BT)5.23 and section 50.5. Do not grant permission to use a partially constructed road if there is danger of resource damage or safety is impaired. The purchaser may haul timber adjacent to the road or in the right-of-way before the road is substantially completed. 51.2 - Construction Cost Adjustment (B(BT)5.25). There are cost adjustment contract provisions for variations in quantity, physical changes, and design changes. 51.21 - Variation in Quantities (C(CT)5.251#). This contract provision describes how to adjust costs for differences between contract quantities of rock and culvert and measured quantities. There must be advance agreement by the Engineering Representative for changes to the contract quantities. 51.22 - Physical Change (C(CT)5.253). This contract provision applies only to roads not accepted under contract provision B(BT)6.35. Adjustments may be made when a landslide, rain, fire, earthquake, and so forth, causes an increase in costs because of washouts, slope failure, slumps, windfall, and so forth. For each road, consider all the damage caused by an event as one revision. The adjusted costs must include the quantities of work abandoned. Revise costs for physical change only when damages caused by the event result in extra costs of (1) more than $1,000 or (2) more than 10 percent of the purchaser credit limit, whichever is less. Physical change does not include damage due to purchaser's negligence. 51.23 - Design Change (C(CT)5.254). This contract provision defines the procedures for implementing design changes. These can be either mutually agreed to or ordered design changes. 51.23a - Mutually Agreed to Design Change. Contract provision C(CT)5.254 provides that either the purchaser or the Forest Service may propose a mutual change. Only properly designated representatives of the purchaser and the Forest Service can approve a mutually agreed to design change and only when the proposed change is not to the disadvantage of the government. 51.23b - Ordered Design Change. The Contracting Officer may order the purchaser to perform work that results in a change in costs under contract provision C(CT)5.254. Make ordered design changes in response to differences between anticipated and actual field conditions. Such changes must be necessary in order to construct roads to the standard on the plans and to ensure the stability of the road. Work needed to prevent damage to soil and water immediately adjacent to the road may also be included. The Forest Service must pay the purchaser for any increase in ineffective purchaser credit. Some examples of ordered design changes are: 1. Location changes, including redesign of a road to avoid unstable soils or to move the location away from streams. 2. Changes in road cross section. 3. Addition of or change in base thickness to support design traffic load. 4. Change in backslope angle or ditches, change from ditched to inslope roads, and deletion of slope protection. 5. Change in culvert size or type or redesign of footing and other accessories. 51.23c - Minor Change. Contract provision C(CT)5.254 also defines minor changes for which there will be no reimbursement. Examples are: 1. Adjustments in horizontal or vertical alignment that do not exceed tolerances. 2. Changes in culvert locations when there is minimal change in installation methods. 3. Changes in turnout locations that cause minimal change in clearing or excavation. 4. Changes in log deck location that cause minimal change in clearing. 51.3 - Alternate Facilities (B(BT)5.26). If the purchaser needs a different road than that specified in the contract, a road may be added to contract condition A(AT)9. Location, design, and easements must be fully acceptable as part of the national forest transportation system (FSM 7703) and be included in an environmental analysis. There may be instances where portions of an alternate facility are at a lower standard than is necessary for the sale. The specified road cost for alternate roads (including engineering performed by the purchaser) cannot exceed the cost of the unconstructed specified roads that they replace; although, some adjustments are possible under contract provisions B(BT)5.25 (sec. 51.2) and B(BT)3.3 (sec. 42.13). After the Contracting Officer has agreed to a purchaser's proposal for an alternate facility and established the revised specified road cost, consider this alternate road to be the same as any other road listed in special condition A(AT)9. 51.4 - Purchaser Credit Computation (B(BT)5.3). 1. Computing Purchaser Credit. The normal procedure for computing purchaser credit is for the Engineering Representative to make monthly estimates of the progress of the purchaser's construction activities on specified roads. Use the cost estimates in the schedule of items by road or road segment as a guide in estimating. The purchaser credit allowed is an estimate of accomplishment (such as 20 percent of excavation), including materials furnished and delivered by purchaser, evaluated on the basis of the cost estimates by construction phases shown in the schedule of items. Actual expenditures by the purchaser may be helpful in making these determinations but are not controlling. Record estimates of progress by construction phases on form FS-2400-21, Report of Purchaser Credit for Specified Road Construction. After obtaining approval of the estimates from the Forest Service Representative, credit the purchaser's timber sale account. 2. Crediting Construction. The contract provides that the Forest Service shall credit the purchaser's account with 95 percent of the estimated value of work completed until the Forest Service either accepts a reasonable portion of the road or a project segment or abandons it because of either a physical change described under contract provision C(CT)5.253 or a catastrophe under contract provision B(BT)8.33. 3. Crediting Road Reconstruction Cost Share and Other Deposits. Crediting of the timber sale account for road reconstruction, cost-share road, or other deposits must be in the full amount at the time of deposit, rather than 95 percent as in the case of other construction items. 51.5 - Road Maintenance (B(BT)5.4 and C(CT)5.4). The contract provisions relating to road maintenance are B(BT)5.4 and C(CT)5.4. Supporting documents include the sale area map, the road maintenance deposit schedule (C(CT)5.41#), contract road maintenance requirements summary, and the regional road maintenance specifications. Proper road maintenance includes promoting safe use of roads, protecting substantial investments in permanent roads, preventing excessive loss of road material, protecting roads from seasonal weather damage, and safeguarding soil, water, and other resources. Purchasers are responsible for maintaining forest development roads commensurate with their use. (FSM 7732 and FSH 7709.58, Road Maintenance Handbook, ch. 10, contain procedures for commensurate use determination.) Delegations from the Contracting Officer determine whether the Engineering Representative, Sale Administrator, or another individual is responsible for compliance checking of road maintenance requirements. 51.51 - Prehaul, During Haul, and Post Haul Maintenance. The Engineering Representative and/or Sale Administrator should be thoroughly familiar with the condition of roads prior to purchaser's use and be prepared to present facts to establish maintenance responsibility. A series of photographs taken prior to the log hauling operation at photo points such as route markers, curves, drainage structures, and so forth, may save much controversy at a later date. The purchaser must perform prehaul maintenance needed to facilitate the Forest Service's safe and practical inspection of the purchaser's operations or needed to prevent resource damage tributary to the road. Performance of prehaul maintenance needed for efficiency of operations is discretionary with the purchaser. It is the purchaser's responsibility to maintain the road during log haul in no less than the same condition that existed prior to log hauling. The exception to this rule is when the purchaser is required to cross ditch and close roads to meet Level 1 maintenance objectives (FSH 7709.58). 51.52 - Road Damage. Repair of road damage caused by the purchaser's operations is the responsibility of the purchaser (contract provision B(BT)5.12 and B(BT)6.22). Repair of road damage caused by other than the purchaser's operations is the responsibility of the Forest Service. The purchaser is responsible for repairing damage and maintaining roads to the extent required by the contract on all roads where purchaser's use has begun. Repair of damage to roads which the purchaser has not begun to use is the responsibility of the Forest Service. The Forest Service is also responsible for repairing road damage caused by natural events and public road use in excess of normal traffic. 51.53 - Preventive Maintenance. During the last 30 days of the normal operating season, ensure that the purchaser is current on all needed winterizing work. When the first storm arrives, it is too late to do satisfactory winterizing work. It is impractical to expect an operator to be able to do satisfactory preventive maintenance work on more than a few miles of road once the first severe storm arrives. Therefore, operators must be near completion on winterizing needs during critical periods of time. Proper preventive maintenance can help avoid road damage due to winter weather. Provide the purchaser with a deadline in writing for completing all required winterizing during the last 30 days of the normal operating season and as long thereafter as operations continue. If the purchaser does not meet the deadlines and damage occurs, take contractual action under contract provisions B(BT)6.65 and/or B(BT)6.22 to correct the situation. 51.54 - Maintenance Deposits (C(CT)5.41#). Ensure that road maintenance and surface replacement deposits for all road segments listed in the contract road maintenance requirements summary in contract provision C(CT)5.4 are billed for and collected. The Forest Service and the purchaser may agree in writing to an adjustment of road maintenance rates if, for example, the purchaser wants to haul timber when road surfaces may wear more rapidly. If the purchaser uses roads not listed in the C(CT)5.4 contract road maintenance requirements summary, charge road maintenance deposits commensurate with the purchaser's use. 51.55 - Temporary Roads. Ensure that temporary roads receive the maintenance, including dust abatement, necessary for safety and for adequate protection of adjacent resources. Traffic control measures may be necessary for public protection. 51.56 - Water Sources. Be familiar with downstream demands on water use and the effects that water sources may have on this use. When choosing and developing water sources, obtain specialist input as needed. Use contract provisions B(BT)6.5 and/or B(BT)6.34 to control water source development and use. 51.57 - Road Maintenance Specifications. Ensure that the Forest Service and the purchaser meet regional road maintenance specifications which prescribe the expected end result for road maintenance performed by either party. The contract road maintenance requirements summary lists the specifications applicable to individual roads. 51.57a - Slide Removal and Slump Repair. This activity includes slide removal and repair of slumps and washouts that is not routinely handled by a motor grader during ditch cleaning or surface blading operations. If the contract shows the quantity of slide removal and slump repair deemed normal in the appraisal estimate over the term of the timber sale for all roads with purchaser maintenance responsibility, this quantity is the maximum volume of purchaser responsibility during the life of the timber sale contract. Measure and credit as slide removal the quantity of material removed from slides and used to repair slumps or washouts. Measure and credit slump and washout repairs only if material used in repairs comes from areas outside the existing roadway. Do not credit the quantity of slide removal and slump repair work performed due to catastrophic damage. If the total slide and slump repair volume exceeds the quantity shown in the contract, the work becomes the responsibility of the Forest Service. The sale area map shows the disposal sites for unusable slide material and borrow sites for slump repair materials. Normally, limit compaction associated with slump repair to layer placement and compaction by hauling and spreading equipment. 51.57b - Ditch Cleaning. This activity includes cleaning roadway ditches and incorporating the material into the traveled way on unsurfaced roads or end hauling the removed material on surface roads. The sale area map shows disposal sites for unused material removed from ditches. Disturbing stabilized ditches adds to the movement of soil and increases resource damage; therefore, require or perform selective ditch cleaning only where obstructions would cause improper drainage. Remove rocks that are in the ditch if they are hazardous to the road user. Do not disturb stabilized ditches, over-excavate ditches, and undercut backslopes. Require cutting and removal of growing brush and small trees which interfere with the flow pattern of the ditch. Follow the specification of the regional roadway vegetation road maintenance specification. Do not permit contamination of surfaced roads with material removed from ditches. Avoid contamination when cleaning ditches by utilizing a front end loader and hauling the material to a disposal site. 51.57c - Surface Blading. This activity includes blading the existing road traveled way. It does not include reshaping the roadway. Assess the design and cross section of roads prior to the purchaser's use in order to provide a basis for comparison when determining adequacy of surface blading. Where possible, use material returned from the shoulder or turnouts and slough material to fill washouts and ruts. Do not establish new berms. Use side-casting for disposal for oversize material generated from surface blading activities, unless shown otherwise on the sale area map. Light scarification to remove surface irregularities is within the scope of the activity. Surface blading needed for the preparation and application of dust abatement treatment is part of the dust abatement activity. Perform surface blading only where and when necessary. Spot blade the portions of the road which need blading to maintain surface stability. Do not surface blade with dry material; use the proper amount of water to produce a compact and durable riding surface. 51.57d - Surface Repair. This activity includes repairing small soft spots and potholes that occur in the traveled way. It also includes skin patching and repairing asphalt dikes. 51.57e - Drainage Structures. This activity consists of maintaining drainage structures and appurtenances. It does not include replacing or adding drainage structures. Engineering Representatives or Sale Administrators should check for proper drainage structure maintenance during haul, at the end of annual operations, and before terminating the use of the road. 51.57f - Dust Abatement. This activity consists of preparing the traveled way and furnishing and applying materials to abate dust. The objective is to promote safe use of roads, to prevent excessive loss of road material, and to protect adjacent resources. Regardless of the quantity of material estimated in the appraisal for dust abatement treatment, the party responsible for this activity must provide the quantity needed to abate dust. Administer dust abatement treatment as preventive maintenance, rather than reactive maintenance. Advise purchasers in writing, at the preoperations meeting, of their responsibilities to fulfill their dust abatement obligations in a timely manner. The application of the dust abatement material must conform with the contract and meet the regional road maintenance specification requirements. Prepare the road to meet the dust palliative specifications prior to applying the treatment. Inadequate preparation may shorten the effective life of the dust abatement material. When using materials other than water for dust abatement, require the purchaser to furnish a certification from the supplier stating the content and properties of the mixture. Ensure that a spill prevention control and countermeasures plan, as required by contract provision C(CT)6.341, is in place prior to application of dust abatement materials other than water. Use established administrative procedures for road closure if necessary to protect investments and ensure public safety during application of dust abatement materials. 51.57g - Roadway Vegetation. This activity includes removal of brush and trees from within the roadway limits. Ensure that consideration is given not only to sight distance for safety, but also to the adequate removal of vegetation to facilitate surface blading, ditch cleaning, and so forth. 51.57h - Miscellaneous Structures. This activity covers maintenance of gates, cattleguards, and other similar structures. 51.6 - Traffic Regulation. State traffic regulations apply to roads controlled by the Forest Service. Contract provision C(CT)6.0 requires that the purchaser obey State laws. Contract provision B(BT)6.33 requires that the purchaser's operations allow safe inspection of the timber sale. If the purchaser's violation of these regulations causes a safety problem on the sale area, the Forest Service Representative should put the purchaser in breach of the contract. If traffic violations are occurring off the sale area, notify Forest Service law enforcement of the need for enforcement. Designated members of the sale administration team must also administer contract provisions that apply to traffic regulation. 51.61 - Contractual Traffic Regulation. The following timber sale contract provisions apply to the enforcement of traffic regulations on forest development roads: 1. C(CT)5.12# - Use of Roads by Purchaser. Purchaser's use of specific roads is prohibited or restricted per limitations as shown on the sale area map and the road or bridge regulation list. 2. C(CT)6.33 - Safety. This contract provision requires that the purchaser furnish a written traffic control plan for each project with the intent of providing public safety through the use of established traffic control standards. 51.7 - Purchaser Elected Government Construction of Roads. Small businesses may elect to have the Forest Service construct specified roads when the estimated cost of construction exceeds $20,000. When a bidder elects government construction, the work is then performed through a public works contract. Maintain close coordination between the Sale Administrator and the Contracting Officer's Representative for the public works contract during road construction in order to meet sale objectives. Examples of this coordination include, but are not limited to: 1. Monitoring the progress of construction as it relates to contract provision (CT)5.101# - Road Completion Date. 2. Ensuring that the contractor meets log accountability, export, utilization, scaling, and log haul requirements. 3. Assisting the Contracting Officer's Representative in the administration of the utilization and fire requirements of the public works contract. 4. Assisting the Contracting Officer's Representative in agreeing with the purchaser on construction slash disposal areas and right-of-way decking areas that can also be used during harvesting operations. 5. Assisting the Contracting Officer's Representative in the selection of contractor's campsites and work staging areas. 51.8 - Temporary Roads (B(BT)5.1). The primary function of temporary roads is to provide access to landings with the least impact on the natural resource. Accordingly, control points for temporary roads are as much determined by satisfactory landing locations, stand protection, watershed protection, and other resource protection considerations as they are topographic controls. Contract provision B(BT)5.1 - Authorization, is used to agree on the location and clearing limits of temporary roads prior to construction. Fully document agreements under this contract provision, including how the road will be stabilized and closed. Mark location and clearing limits on the ground as needed to achieve resource protection objectives. To achieve resource protection objectives in temporary road construction activities, the following fundamentals are recommended: 1. Location. Do not limit temporary road location considerations solely to meeting timber harvest needs. Carefully weigh additional considerations, such as drainage, ease of meeting stabilization requirements, natural opportunities for barricades, water quality protection, aesthetics, and so forth when locating temporary roads. 2. Clearing. Clearing limits of temporary roads should be marked on the ground to establish control. They should be designed to facilitate the required method of temporary road slash disposal and to designate the right-of-way timber under contract provision B(BT)2.32 - Construction Clearing. When locating temporary road clearing limits outside payment unit boundaries on tree measurement sales, ensure that merchantable timber within the clearing limits has been marked, measured, and paid for prior to felling. 3. Excavation. Construction of temporary roads should normally rely on self-balanced construction methods. Minimize extensive throughcuts. 4. Drainage. Strive to construct temporary roads that take advantage of natural features to achieve drainage. Be specific in written agreements for temporary road construction with regard to drainage, such as outsloping, berms, and so forth. 5. Density of Roads. The timber sale planning intent related to temporary road density can be found in the environmental analysis and/or timber sale appraisal reports and maps. Temporary road density is based on resource objectives, topography, and the commonly accepted skidding and yarding distances in the area. 6. Coordination with Permanent Roads. Ensure that timber haul from temporary roads compliments the forest development road system. Locate temporary road approaches to forest development roads to ensure safety and protection of investments and resources. 7. Streamcourse Crossings. Contract provision B(BT)6.5 - Streamcourse Protection, requires use of culverts or bridges at all points where it is necessary to cross streamcourses with temporary roads. Do not use log fills in live streams or streams that are anticipated to be live during the period of expected use. Ensure that culvert diameter is adequate to carry the flow and culvert length is adequate for embankment cover. 8. Maintenance. The major objectives of temporary road maintenance are user safety and protection of resource values. 9. Stabilization and Closure. The final treatment for temporary roads, after the purchaser's use is completed, is described in contract provision B(BT)6.62 - Temporary Roads. This treatment is designed to reduce erosion and preclude further use of the road, as required by the National Forest Management Act of 1976 (16 U.S.C. 472a).
