SPECIAL PROJECT SPECIFICATION
SECTION 185 - ROAD DESIGN, RECONSTRUCTION April 25, 1997
185.01 Work. This work consists of the design of roads using geometric or non-geometric
design methods, as designated in the Schedule of Items. The design objective is to
minimize quantities of excavation & embankment while conforming to the design standards and
guidelines. The work includes furnishing all labor, transportation, materials, equipment, and
other incidentals necessary to complete the design in accordance with these specifications and
acceptable engineering practice.
Accomplish the design under the direction of a registered professional engineer as required by
applicable State laws. This requirement is waived under the industrial exemptions of the applicable
State laws relating to professional licensing when the work is performed under the requirements of a
timber sale contract by the timber purchaser's employees.
185.02 Government Furnished Information. The Contractor will be furnished access to the
following information, as appropriate:
(a) Design Criteria, Elements, and Standards
(b) Survey Notes
(c) Applicable portions of Forest Service Manuals and Handbooks
(d) F.S. Specifications for Construction of Roads and Bridges, EM-7720-100
(e) Region 6 Special Project Specifications
( f) Environmental Analysis of the area to be accessed by the road.
(g) Sample plans, specifications and drawings.
(h) Typical detail sheets
The Contractor will also be furnished with the computer program software, including
documentation, which is to be used for all non-geometric road design computations. Supply
computer program software for geometric road designs.

185.03 General. Complete the road designs required under this contract to conform to the design
standards & criteria and accomplish the objectives set forth in the appropriate environmental
185.04 Design Computations. Use the computer software furnished by the Government under
Subsection 185.02 for all non-geometric design computations. Contractor furnished software for
geometric designs must compute earthwork by the average end area method, compute clearing area
in horizontal measurements, and compute seeding area in surface area measurements.
185.05 Field Review and Classification Notes. Review the road(s) to be reconstructed on the
ground to become familiar with the topography, drainage, and environmental conditions traversed
by the survey prior to initiating design. Prepare classification notes for the road which shall provide
information on clearing, grubbing, soils, rock, drainage, geotechnical investigation needs, potential
disposal sites, etc.
Classify soils and rock in accordance with the following:
Material Type Classification
Organic Material Unsuitable
Soil and Loose Rock Common
Rock which can be moved Rippable
Rock which requires blasting Solid Rock
Boulders Boulders (list size range)
185.06 Design Criteria. The design criteria are those requirements such as management area
direction, road management objectives, safety requirements, and traffic characteristics that
govern selection of design elements and design standards. This information will be provided to
the Contractor as background material which led to development of specific design elements and
185.07 Design Elements and Standards. The specific road design elements and standards
for the road(s) comprising this project will be provided to the Contractor. A description of how
these elements and standards are applied to the design process is contained in Forest Service
Handbook FSH 7709.56 - Road Preconstruction Handbook, Chapter 4.
185.08 Specifications. Complete the design and engineering drawings to utilize and be
compatible with the following specifications:
(a) Forest Service Specifications for Construction of Roads & Bridges, EM-7720-100.
R6/SPS 185 ROAD DESIGN, RECONSTRUCTION 4/25/97 2
(b) Region 6 Special Project Specifications for Construction of Roads & Bridges.
(c) Forest Special Project Specifications for Construction of Roads and Bridges.
Instances may be found where the standard specifications are inadequate. In these cases,
prepare additional Special Project Specifications to accomplish the intent of the design. All
Special Project Specifications proposed by the Contractor shall be approved by the Contracting
Officer prior to inclusion in the final design.
185.09 Design Products. Furnish the following products, in the quantities specified, to the Forest
(a) Engineering Drawings. Furnish one (1) set of reproducible and two (2) set of prints of
the final engineering drawings. Format drawings on 280mm x 430 mm sheets, unless otherwise
approved by the Contracting Officer. Conform drawings to samples provided, with exceptions as
noted by the Contracting Officer.
Include the following sheets, as appropriate, and assemble in the same order:
1. Title Sheet
2. Vicinity Map
3. Estimate of Quantities
4. Typical Sections
5. General Notes (notes furnished by FS shall be incorporated)
6. Drainage Listing
7. Drainage Construction Details
8. Riprap Details
9. Typical Construction Staking Details
10. Plan & Profile Drawings
11. Reconstruction work list
12. Pit Development Plan
13. Traffic Control Typical
(b) Specifications. Furnish two (2) sets of the following specification material:
1. Specification list showing FS Standard Specifications and Region 6 Special Project
2. Additional special project specifications needed for the road(s) designed as part of
(c) Staking Notes. Furnish the Government with two (2) copies of construction staking notes,
one of which is on moisture resistant paper. Include centerline grade elevation, centerline ground
elevation, centerline cut or fill, template data left and right, slope ratios, offset from P-line
(preliminary) to L-line (location), P-line ground elevation, and information for trial catch points.
Prepare format to include "as staked" information.

INSPECTION AND ACCEPTANCE
185.10 Preliminary Review. Upon completion of a draft copy of the design drawings, notify
the Contracting Officer. Within fifteen (15) working days, the Government will conduct a
preliminary review of the design. This review may include a plans-in-hand field review and an
office review of computations and special project specifications. Within ten (10) working days
after the preliminary review, the Contracting Officer shall notify the Contractor of required
modifications to the preliminary design.
185.11 Final Review. After completion of any modifications resulting from the plan-in-hand
review and preliminary office review, submit revised drawings and specifications to the
Contracting Officer for final review. Within fifteen (15) working days, the Contracting Officer
shall notify the Contractor of any final modifications needed to drawings or specifications before
185.12 Acceptance. Prior to final acceptance of the work, present the Government with final
engineering drawings, specifications, construction staking notes, and working documents used for
design (plots, cross sections, printouts, notes, etc.). The contractor will also return any
government furnished software which was provided for the design of the project.
