SCOPE OF WORK

GENERAL

The purpose of this Task Order is to provide professional survey, preliminary engineering report, geotechnical engineering, and civil engineering design for Forest Service permanent road repairs on the Lumsden Road. Road damage was caused by high intensity and extended duration rainfall events in the Winter and Spring of 2023.

DRAFT

The project sites are located on Forest Route 1N10, Lumsden Road, approximately 10 miles from Groveland, California.

Design services include topographic survey, geotechnical site investigation, design of any structures needed to re-establish the road section and road design for each site. All work is to be completed under the direction of a Professional Engineer (PE) licensed in California. The two sites to be addressed are:

1. Lumsden Road Milepost 9.17 Provide engineering site survey and design for the site.

The site is a combined cut slope and fill slope failure.

2. Lumsden Road Milepost 10.21 Provide engineering site survey and design for the site. The site consists of two fill slope failures approximately 200’ apart.

The proposed design shall be of best value to the Government, including considerations for cost, suitability, and resiliency. The preferred least cost alternative developed by the Forest Service is outlined in the provided Detailed Damage Inspection Report (DDIR). It is the responsibility of the contractor to verify the suitability of this alternative. If the Contractor wants to propose an alternative repair method, the Contractor must request approval for the alternative repair methodology. Any alternative to the already approved design methodology presented in the DDIR shall require a justification identifying why the selected design is of best value to the Government.

The Contractor shall furnish all materials, supplies, equipment, transportation, and personnel to provide engineering services described in this task. During the prosecution of work, the Contractor shall provide adequate professional supervision and quality control to ensure the accuracy, quality, completeness, and progress of the work.

Preliminary drawings and quantities developed by the Forest Service are included in Appendix A – Detailed Damage Inspection Reports (DDIRs). Additional information regarding each site, such as road data, classification, preliminary assessment and repair notes, and images are also included in each report. Field information provided in the DDIRs is for informational purposes only. It is up to the Contractor to independently verify assumptions, or any other information contained within field notes, or any other data/information provided by the Forest Service.

SUMMARY, BACKGROUND, AND DEFINITIONS

Summary – The Stanislaus National Forest maintains an extensive road network to access the national forest for recreation, commerce, and emergency response. Lumsden Road is a primary access to recreational opportunities on the Tuolumne River and is heavily used by recreationalists during the summer months. Most work associated with maintaining this road is relatively routine – grading, culvert maintenance, and resurfacing. However, at an increasing frequency, storms and wildfires are causing widespread damage to this road leading to required repairs any given year.

Background -- The soil types encountered on most sections of the Lumsden road are erodible/cohesionless residual and colluvium - primarily SM/GM.

Slope angles where failures occur are generally in a narrow range – 35 to 45 degrees approximately.

Because the slopes are relatively steep, achieving an adequate foundation under walls can be challenging especially along wall toes. Where walls are needed and adequate setbacks are difficult to achieve without significant excavation foundation improvements, soil nails have been used to transfer high vertical stresses and improve bearing capacity.

Seismic stability evaluation is required.

Except in the case of large infrastructure projects extensive geotechnical investigations which involve drilling are rarely conducted. Field investigations, site surveys using field measurements, field testing (DCP, portable SPT, static cone, Schmidt hammer, torvane, pocket penetrometer…), and geophysics with tight shot spacing are commonly employed. Existing (2019) lidar will be provided to assess pre-failure road profiles.

Site conditions can change significantly between design and construction. The Contractor should plan accordingly.

Native materials are utilized for construction on most projects within the Forest Service due to significant costs related to haul. If Native Material is used, design elements to mitigate the use of less-than-ideal soils may be required. Design elements and calculations should incorporate the materials that will be used for project implementation, and supplemental specifications may be required based on those designs.

Forest Service Offices

District Office - The office is responsible for the management of a subsection of a forest or grassland contained in the National Forest System (NFS). It is managed by the District Ranger. The District Ranger is responsible to the Forest Supervisor.

Supervisor’s Office (S.O.) - The office is responsible for the management of a forest or grassland contained in a region within the NFS. It is usually named after the forest or grassland it is managing. It is managed by the Forest or Grassland Supervisor who is responsible to the Regional Forester.

Regional Office (R.O.) - The office is responsible for the management of a Region contained with the NFS. The regions – 1, 2, 3, 4, 5, 6, 8, 9 and 10 – comprise the NFS.

It is managed by the Regional Forester who is responsible to the Chief (Washington Office) of the Forest Service.

USDA AND FOREST SERVICE SECURITY REGULATIONS, POLICIES, AND

GUIDELINES

The Contractor will be responsible for ensuring compliance with Departmental and Federal Policy and guidance during the execution of the Task Order which may include, but not limited to,

• Forest Service Handbook and Forest Service Manual

• Standard Specification for Construction of Roads and Bridges on Federal

Highway Projects FP-14

• AASHTO

• ASTM

• Guidelines for Geometric Design of Very Low-Volume Local Roads

The specific policy and references utilized in the execution of this Task Order will be determined after the award during the kickoff meeting. The final determination will be made by the Contracting Officer. The specification to be used in design is the most recent version of the applicable specification or requirement excepting the FP-14, which shall be used in development of the project specifications. Follow all industry standards utilizing Load Resistance Factored Design where applicable. Where not applicable, justify the use of Allowable Stress Design. Where compliance with the above standards is not possible, justification must be provided and approval by the Government will be considered on a case-by-case basis.

WORK TO BE PERFORMED

Each Task and Subtask listed in this section are the deliverables associated for the execution this task order.

The Contractor will coordinate with the regional POC listed in Section 5B. The regional POC, in conjunction with the Forest POCs, will coordinate with the Contractor.

The Contractor is expected to have significant experience developing designs in steep terrain utilizing conservative assumptions related to in-situ and overall site conditions, at times relying on this experience where some geotechnical exploration techniques are cost prohibitive relative to the preferred design alternative.

Task 1: Geotechnical Investigation Geotechnical Investigation. A geotechnical investigation will be conducted for each site to determine site soil characteristics needed for alternatives and final design. Conduct preliminary investigation work to identify the anticipated subsurface conditions at each location. Provide a report that includes recommendations for each site. The report shall include, but is not limited to relevant soil properties encountered, lateral pressures, construction considerations, engineering analysis, and recommendations. This activity involves a site visit to the impacted areas and preliminary work to gather data to develop conceptual designs. Coordinate with the COR to schedule field work. A Forest Service representative may accompany the Contractor during the site visit.

Retaining Wall Structural Performance: Provide retaining walls capable of withstanding the effects of gravity loads due to soil pressures indicated and determined according to AASHTO LRFD Bridge Design Specifications latest edition.

Global stability minimum factor of safety 1.3 static and 1.1 pseudo or as approved by

CO.

Task 2: Topographic Site Map Topographic Site Map. Contractor will provide electronic site map and data in a format compatible with AutoCAD Civil 3D 2023. Provide point files in PNEZD comma delaminated format, along with survey notes and descriptions, AutoCAD files, and PDF files of the topographical survey for each site. As a minimum the topo survey shall locate all manmade features within the survey limits i.e. edge of road, culverts, guardrail, gates, fencing, etc.

Include at a minimum 3 rebar and cap control points for each site beyond areas likely to be disturbed.

Task 3: Preliminary Engineering Report Preliminary Engineering Report. Prepare an engineering report for each site that describes the site and feasible alternatives for repair. Design report shall address, but is not limited to concerns related to global stability, internal stability if structures are designed, adequacy of the structures foundation and bearing, and fire resiliency and cost.

The report shall provide options, preliminary cost estimates, preliminary quantities, sketches, and recommendations.

Task 4: Civil Design, Plans, and Specifications Design, cost estimate, and related contract documents will be developed under this task.

The contractor will develop designs to re-establish each site to pre-failure conditions.

For roads pre-failure conditions means the reconstruction of the roadway to its pre-failure lane widths, vertical, and horizontal alignment. The Contractor will,

1) Develop designs, drawings, cost estimate, schedule of items, and for inclusion in contract documents and the execution of each project. Plans and specifications for each site shall include road alignment and cross-sectional repair including and appurtenant features such as embankments, retaining walls, culverts, site grading, etc.

2) Civil design will utilize topographic surveys completed in Task 2, electronic design plans, and data in a format compatible with AutoCAD Civil 3D 2023.

3) Develop conservative design assumptions when inadequate data exist. Design assumptions will be clearly indicated. Designs should include alternatives for deep vs shallow instability of soil or rock and whether rock is shallow or deep as necessary that address potential variations in site conditions that may be encountered during construction.

4) Ensure stability against existing and future watershed conditions that may threaten the structure. This is especially true in watersheds where hydrology/geohydrology has been altered by wildfire, areas subject to repeated debris flow risk, or are in areas where wildfire events are probable over the design life of the structure. This may include storm proofing to abate the impacts of extreme hydrologic events and debris flows. This may include consideration of the structure durability when exposed to extreme temperatures resulting from wildfire events.
