General Information and Instructions

Significant changes in the 2007 Cost Guide:

In the Engineer’s Estimate section, a table of adjustment factors to be applied to the unit costs published in the Guide has been added. The purpose of these adjustment factors in Table 3 is to compensate for the difference between Davis-Bacon wage rates across the states within the Regions covered by the Guide.

The unit costs published in the Guide were developed using Idaho Zone 1 wage rates and equipment rates. The Davis-Bacon wage rate adjustments must be applied to all unit costs published in the Guide if the project is outside Idaho Zone 1.

In addition, an adjustment factor table to compensate for differences in equipment hourly rates appears in the Engineer’s Estimate section. For projects in Colorado, Idaho, Kansas, Nebraska, or Nevada no adjustment is necessary. See Table 4 in the Engineer’s Estimate section.

The maps previously used to show the Davis-Bacon wage rate zones have been removed. A description of the zones by counties appears in the Engineer’s Estimate section for each state.

A section for Temporary Road Cost Estimating has been added and follows Section 600 in this Guide.

1. Revisions and Updates. There is one annual revision of the Cost Guide that is typically published in February.

The Forest Service has adopted the FP-03 (Standard Specifications for Construction of Roads and Bridges on Federal Highway Projects. This has resulted in a major change in the cost guide and required a set of FSSS (Forest Service Supplemental Specifications) so that the specifications will conform to the Forest Service contract requirements. As a result the descriptions of the specification items have changed for some of the items and many of the specification numbers have changed. The items have also been rearranged. However, the content of the information in this cost guide has changed very little except for the updated costs. The FP-03 and FSSS are available in either Metric or US Customary (English) units.

Verify that cost estimates allow for all work required by the various FSSS in the contract. Since the FSSS are being modified over time, unit costs shown in this guide may not accurately reflect the work required.

2. Time and Equipment (Construction) Estimates. On some items, it may be necessary to develop estimates by "time and equipment." When making time and equipment estimates, be sure to include allowances for:

A. Supervision. On very small jobs this may be provided by an operator/supervisor at essentially no additional cost.

B. Taxes on purchase of material. Also, allow for delivery cost to job site.

C. Bonding cost (may be included in Section 151 Mobilization).

D. "Standby time" for equipment and operators that are part of a "spread" performing a segment of work, but who are not working at full capacity all the time, averages 2 to 2 1/2 percent of the total contract cost. For example, during placement of aggregate, a grader, roller and water truck are needed. The grader and roller may be operating full time; the water truck only part time. The estimate should include standby time for the water truck to compensate for having it available on the job during the entire time of placing aggregate.

E. Support Equipment - fuel trucks, pickups, crew transportation, etc.

F. Permits.

Please note that the labor and equipment rates shown in the Cost Guide include applicable "payroll loading" and profit and overhead costs.

(03/2007) - 9

3. Unit Costs. The estimator should round off the unit price to avoid creating accounting errors when processing contract payments. For example, clearing costs generally should be rounded to the nearest $10 per acre, excavation costs should be rounded to the nearest $.10 per CY, and CMP costs are rounded to $.50/LF. Quantities should never be carried out further than the nearest one-hundredth (0.01), and generally no further than the nearest one-tenth (0.1), depending on accuracy of measurements and cost or value of the item.

4. Use of Average Cost in Project. Use average cost for individual roads within the project whenever possible unless there are significant variations in the character of work from one road to another. Variations are sometimes appropriate for clearing, excavation, hauling, or other unique situations. In these situations, each road should have separate and distinct unit costs for those items; otherwise, the use of overall project unit costs may create problems with design changes, alternate facilities, etc.

5. Profit and Risk Factor. The profit and risk factor used in this Cost Guide is 10 percent. All unit prices shown in the Guide include this allowance, including the wage and equipment rates.

6. Section Number. The Specifications are referred to by Section Numbers in FP-03. The Section Numbers are further broken down by paragraphs with decimal points (i.e. 213.08). Supplemental Specifications are referred to as Forest Service Supplemental Specifications (FSSS). The FSSS’s replace or modify the parent specification.

7. Pay Item Number. Pay item numbers and descriptions are found in the Spec Manager database in Lotus Notes rather than in the FP-03 book.

8. Public Works & Timber Sale Estimates. All engineer's estimates for road construction are to be prepared as if construction is to be accomplished by a public works contract. Unit costs for work items listed in this cost guide utilize Davis-Bacon wages.

9. Davis-Bacon (D-B) /Purchaser Wage Rate Adjustments: To arrive at Specified Road Construction Cost, the engineer's cost estimate shall be adjusted by the estimated cost difference between the applicable Davis-Bacon wage rates and the local prevailing wage rates using the appropriate labor factor given for the labor percentages shown for each work item. These adjustments are mandatory and will be used for all timber sale contracts having specified road construction. Note that some work items are not normally performed by a Timber Sale Purchaser but are subcontracted. No reduction should be made for these items, if the subcontractor is likely to pay Davis-Bacon wage rates. Reductions will be made for those situations where it is unlikely that D-B wages are paid. Refer to FSH 7709.56-7.54 (Preconstruction Handbook) for more information, and refer to Labor Rates in the Engineer’s Estimate section of this Guide for D-B wage information. An example of this may be dust palliative treatments. For additional information, see section entitled Davis-Bacon/Purchaser Wage Rate Adjustments.

10. Fuel Prices. Fuel costs can be quite variable over a period of time due to geopolitical conditions. Equipment Rates in Section 622 and elsewhere in this Guide may need to be adjusted by the estimator to compensate for these variations. Other machinery/equipment that uses fuel or propane such as asphalt plant dryers, generators, etc. may also cost more/less to operate. The overall effect on the typical road construction project is that 30-40% fuel price increases will increase the total cost of construction about 2-5%. The estimator should be aware of big (10% plus) fuel price increases/decreases that would affect the unit bid prices shown in this Guide. Fuel price variations will have more effect on items that are equipment oriented such as excavation, than those that are material and labor oriented such as signs.

11. Use of Costs Other Than Shown in the Cost Guide. When local experience indicates unit costs are different than those shown in this Guide, local costs should be considered. Cost deviations from this Guide shall be documented and included in the project file.

12. Small Quantity Adjustments. Estimates should consider all roads that are included in a contract package that are within a five mile radius as one project for the purposes of small quantity adjustments. Therefore, small quantity factors should not be applied to individual road costs when the individual roads are part of a larger group of road projects in the same vicinity and part of the same contract. On the other hand, where small quantities are involved, estimators should increase allowances due to the inefficiencies generally encountered in small projects. Of particular concern are projects where small quantities of aggregate are involved. Mobilization of equipment may outweigh the direct costs of the aggregate, short road construction projects also have a relatively high mobilization cost for transport of dozers and excavators.

(03/2007) - 10

13. Purchaser Engineering. Recent changes in Forest Service FRP budgets have introduced or revised several concepts for timber sale roads: post-award engineering (PAE) including possible purchaser survey and/or design, restricted public use of haul routes, deposits for engineering work on road reconstruction, converting some planned short-term specified roads to temporary roads that remain open for a short period after purchasers use, and use of salvage sale funding for engineering work. Estimator should refer to specific C-provision requirements when estimating purchaser engineering costs.

14. Change Orders & Design Changes. The principles, costs, etc. listed in this Guide can be used to assist in determining unit costs for contract design changes and change orders; however, site specific and project related information should be used to the maximum extent possible.

15. New FP-03 Specifications. All costs in this guide are associated with the FP-03 and FSSS specifications. Many of the items in the new Specifications have changed and users of this guide should verify that the costs are associated with the same or correct type of work.

16. Electronic Copy of the Cost Guide. This cost guide can be found on the intranet at http://fsweb.r4.fs.fed.us/. Click on STAFFS, then ENGINEERING under the RESOURCES Staff, then TRANSPORTATION, and PLANNING and DEVELOPMENT. Click on the 2007 R2/R3/R4 Cost Guide link to download the complete guide.

The cost guide is available for downloading by the general public at: www.fs.fed.us/r4/, click on Projects & Plans, then on the Cost Estimating Guide link to download.

The cost guide will be updated whenever new data is available or as corrections are needed. The annual update takes place in February of each year.

17. Summary. This is a guide and not a cookbook. Estimators need to use judgment and knowledge of the specific project and local conditions when preparing cost estimates.

Davis-Bacon/Purchaser Wage Rate Adjustments

Davis-Bacon/Purchaser Wage Rate Adjustment

(03/2007) - 22

Davis-Bacon/Purchaser Wage Rate Adjustments

All road construction projects must first be estimated as if being built by public works contracts using Davis-Bacon wage rates.

For Timber Sale Contracts, the engineer's estimate must then be adjusted to take into account the difference between Davis- Bacon wage rates and the local wage rates paid by timber purchasers. This adjusted construction cost is called the Total Estimated Road Construction Cost. The method to use for the cost adjustment is explained below.

The following labor percentage ranges shown in Tables 1 and 2 are typical and include equipment operators, truck drivers and laborers. The actual percentage selected should be documented. Use of percentages different than those indicated and the reason for the selection should also be documented.

See individual items in text of Cost Guide for other labor percentages. Note that contract items (items not normally accomplished by woods crews such as engineering and asphalt items) are not to be reduced, if the subcontractor is expected to pay Davis-Bacon wage rates. See Labor Rates in the Engineer’s Estimate section of this Guide for D-B wage rate information.

Table 3 below is just for reference and lists the reduction percentages to be applied to the labor costs for each work item based on the state where the project is located. Table 4 on the following page provides the unit costs adjustment factors to apply to the Engineer’s Estimate (Davis-Bacon wages) unit costs based on the percent labor involved and the work zone. An example calculation follows the table.

(03/2007) - 26

TIME ESTIMATES FOR ROAD CONSTRUCTION PROJECTS

Care must be exercised when determining time estimates. The final time estimate should not be made until all contract clauses are known, including applicable C provisions for timber sale contracts. Be sure to consider operating season limitations.

Project access and sequencing must also be considered.

Except in unusual circumstances, the time estimate should not exceed two (2) full construction seasons. This may require increasing the size of the crew and the amount of equipment used in the estimate. In addition, this may require the adjustment of some cost items and contract clauses. For projects that will require more than one construction season to complete, be sure to allow for the cost of the mobilization of equipment and personnel for each operating season.

When the construction of specified roads in a timber sale contract can be turned back to the Forest Service, consider the effect on the road completion date. Allow sufficient time for the Forest Service to prepare a public works contract, receive a satisfactory bid, and have the road construction work completed by the “Road Completion Date” stated in the Timber Sale Contract. A minimum of 150 days should be allowed to prepare, solicit, and award a Public Works contract.

Whenever the Total Estimated Road Construction Cost for a timber sale is $50,000 or more, consider the possibility of a turnback. Use the following form to track the various time components associated with a turnback and to determine if the proposed road completion date to be included in the timber sale contract is attainable.

(03/2007) - 27

TIME ESTIMATING AND SCHEDULING

Road completion date will be set by determining the timber sale advertisement date and adding the following:

Timber Sale (T.S.) Advertisement Date ________

1. Sale Advertising Period 30 Days

Timber Sale Bid Opening Date ________

2. Period specified in the T.S. advertisement to allow the F.S. to solicit and award a

P.W. Contract for the road construction. (150 days minimum is recommended. See note below)

* 150 Days

Public Works Construction Award Date _________

3. Additional time needed between P.W. contract award date and date construction could start.

10 Days

Public Works Construction Start Date ________

4. Total calendar days elapsed time allowed for completion of road construction Public Works contract.

Days

Computed Construction Completion Date ________

5. Additional time for expected excusable delays for P.W. contracts. This time will only be added to determine the road completion date in a Timber Sale (C5.13#) not to determine contract time for a Public Works contract.

Days

Final Road Completion Date ________

Planned Timber Sale Termination Date ________

* The time permissible may vary by local policy. Check with the Timber staff to see if there are any Regional supplements that may dictate the maximum time period.

The time period is comprised of the following items:

80 days for Engineering to convert the timber sale road contract to Public Works format, including modification of supplemental specifications, development of contract documents, and to submit road package to Administrative Services.

Additionally, Job Codes must be set up, Work Plan developed, and IAS data entry and approval process must be completed 10 days to prepare contract documents and posting Fedbizopps.gov by AQM 15 days notice to public prior to solicitation.

30 days advertising period.

15 days to evaulate bids and make award Consider additional time if access to project for pre-bid tour is not available due to inclement weather or other restrictions.

PROJECT REQUIREMENTS

Project Requirements

(03/2007) - 30

SECTION 151 - MOBILIZATION (Labor 30-60 percent)

Mobilization costs are those for preparatory work and operation including bonding and tasks necessary for the movement of personnel, equipment, supplies, and incidentals to the project site, and for all other work and operations which must be performed or costs incurred including obtaining permits.

Average bids reflect that mobilization costs are 6 percent to 10 percent of the total project cost. Smaller projects tend to show mobilization as a higher percentage of the total project cost. The number of move-ins and operating seasons will increase this percentage. Listed are normal percentages for mobilization.

$ 50,000 - $ 600,000 = 9% 600,000 - 899,999 = 8% 900,000 - 1,999,999 = 7% 1,200,000 - over = 6%

These percentages consider a normal project to have two construction seasons. If specialized pieces of equipment or machines are required, the percentage should be increased. If the time and equipment method is used calculate mobilization, make allowances for obtaining permits, insurance, bonds, and moving personnel and materials to the job site.

Roading Costs:

Roading costs can be used for time and equipment jobs, particularly for reconstruction projects. The method for calculating these types of move-in costs would be to determine the time to move to the project site and begin productive operation, then affix proper standby rates, usually 45 to 55 percent of listed rental rates, plus wage rates. For projects of this type and others where mobilization can be readily figured in as an integral part of the listed pay item, it may be unnecessary to include a separate mobilization pay item in the contract. Average roading costs are listed below for some standard equipment:

Equipment Ave. Speed (Mi./Hr)

$ per mile

Grader, Motor Patrol (CAT 12H) 20 5.50

Loaders, CAT 950G 20 5.22

Dump Trucks, 10-12 CY 30 3.35

Water Trucks, 4000 GAL 30 2.95

Service Trucks, 1 TON 30 2.01 Lowboys

35 TON

50 TON

4.63 4.76

Example: Location, Idaho (Area 1, Zone 2)

Total of all pay items without Section 151 = $110,000 Rock Crusher required:

Cost (151) $110,000 x .09 = 9,900

Crusher Movein/Moveout (Section 322) = 9,000 Total Cost Allowance Section 151 = $ 18,900 Total Engineer's Estimate $110,000 + $18,900 = $128,900

Mobilization should not exceed 10% of $128,900, or $12,900 (rounded), so place $12,900 under Section 151 and $6,000 under Section 322.

(03/2007) - 31

SECTION 152 - CONSTRUCTION SURVEY AND STAKING (Contract Item)

A. Road Location. There are no recent costs for this item at the present time.

B. Preliminary Survey. P-Line costs are generally dependent on survey standards, project access (drive, walk, camp, etc), terrain, vegetation density and time schedule. Establishment of spike camps can add costs to a project, long walks or difficult vehicle access can also increase the survey costs.

Detailed surveys of existing roads generally run higher than new construction due to the presence of cut/fill slopes, culverts, and other features. Reestablishment of old P-Line can be estimated to cost about $740/mile, based on using a 2 person crew and a production rate of 1.5 miles per day.

Survey costs for A/E negotiated survey and design contracts should be estimated using the recent contract costs if known.

Additional fieldwork may include items such as material and clearing classification, special site investigation, and stream flow estimates. The engineering firm will normally have a higher overhead cost because a business engaged in survey and design work usually has more office equipment, computers, etc. than a firm specializing in only survey work.

Hourly crew costs below are from RS Means Crew Cost Data Table for Crew A-7. The two-person field party consists of an instrument person and rod person, and is suitable for level loop surveys. The three-person field party consists of a party chief along with an instrument person and rod person, and is suitable for P-line surveys and slope staking.

Wages and Per Diem

a. Fieldwork Per Hour Two-person field party $107 Three-person field party $159 Supervision person $68

b. Per diem $40/person-day

c. Transportation $.50/mile

d. Motel, camp expenses Variable, depends on project location

(approximately $50/day)

The following production rates should be used as a guide in estimating fieldwork:

1. Brushing: Three-person crew. The production for brushing is dependent upon density of stems and will vary with the requirements of the contract:

Density of stems Miles per day Extra heavy 0.35 Heavy 0.5 Medium 0.7 Light 1.0 Extra light 1.5

2. P-line survey: Three-person crew. This work includes collection of traverse and cross section data needed for low volume road design. The production for P-line survey is dependent upon the precision of survey and number of points of intersection (PI's) per mile, and the width of the cross-section swath. For average conditions consider a production rate of a half mile per day of completed work. Costs for completed surveys range from $2150 - $4150 per mile, including supplies(stakes, paint, flagging, etc.), and travel expenses(per diem, mileage, etc.) based on easy terrain and minimal brush.

P-Line Survey Production Rates

PI's per mile Average Spacing(ft)

Miles per Day

176 30 0.35 132 40 0.45 106 50 0.55 88 60 0.68

3. Traverse: Three-person crew. The production for traverse is dependent upon the precision of survey and number of points of intersection (PI's) per mile. This cost estimate is broken down according to the precision desired. It is, therefore, mandatory for the estimator to know the precision required before making the estimate. The chaining difficulty is constant with the number of PI's per mile on which this cost guide will be based. For average conditions consider a production rate of a half mile per day of completed work.

Survey Accuracy Standard Refer to FSH 7709.56, pg 3.9--2 for precision standards

Precision A,B Precision C,D Precision E,F PI's per mile Miles per Day Miles per Day Miles per Day

60 to 70 0.5 0.6 50 to 60 0.6 0.7 40 to 50 0.3 0.7 0.8 30 to 40 0.5 0.8 0.9 20 to 30 0.6 0.9 1.0 10 to 20 0.9 1.0 1.1 5 to 10 1.0

4. Levels: Two-person crew. The production for levels is mainly dependent upon the precision of survey. Therefore, this cost guide is based on average production figures for a given precision. The estimator should use his/her own judgment and adjust these figures if they do not fit the individual project.

5. Cross Sections: Three-person crew. Cross sections are generally constant in production between 0.4 mile to 0.7 mile per day. The brushing for extra heavy and heavy brush are figured in the brushing estimate. Therefore, this item will consider the slope only. If the estimator has unusual circumstances, he/she should adjust the production figures accordingly.

Slope Miles per day 50 percent + 0.4

30 to 50 percent 0.6 0 to 30 percent 0.7

6. Supervision: Allow 1 day per week of survey crew time for supervisory engineer @ $540 per day.

7. Allow move-in/move-out costs, supplies, transportation @ $0.50 per mile.

8. Checking Notes-office work. All notes need to be office checked for completeness. Traverse and level notes need office work in recording and computation for angles and elevation. There is no per diem allowance for this work. Allow 1 to 2 hours per mile for one person at a rate of $52 per hour.

9. Materials Investigation and Testing. See Section 153 or 154 for unit costs.

C. Road Design. (Includes classification, plan & profile, cross sections, and plan-in-hand reviews) Ranges from $2,400 to 3,100 per mile for new construction.

D. Site Surveys. (Cost per site) $2,600 to $5,000 per site. Includes setting control, topo data collection, and plotting site plan.

E. Corner Search, Monumenting, and Boundary Marking & Posting. Contact the Forest Land Survey staff for costs associated with this type of work.

F. Construction Staking:

The base cost for Method II – Catchpoint Measurement Method, is $3,000 per mile. This is based on using a 3 person crew, completing 0.5 miles per day, 120 points per mile, staking cut and fill catchpoints, and setting one RP stake per side. Includes costs for stakes, paint, markers, flagging, travel, and per diem. Average project -- assume camp is within 10 miles of project and access is at the beginning of each job and each job is two miles in length.

Add $85.00 per culvert for culvert staking using the computed Method I. This is based on an allowance of 30 minutes per culvert.

Average base prices should be multiplied by the following factors to determine final…
