About this file

This document is a Forest Service Supplemental Specifications (FSSS) for the La Mina and Big Tree Trail Rehabilitation Construction Project. The project involves comprehensive trail rehabilitation work, with a significant focus on ecological restoration and invasive species management. Key requirements include removing invasive plant species (specifically Odontonema cuspidatum-fire spike) from 10,658.89 square yards on the La Mina Trail and 4,189.56 square yards on the Big Tree Trail, and replanting with 400 native tree species sourced locally in Puerto Rico from a pre-approved list of 21 species.

The specifications provide detailed technical requirements for plant removal, site preparation, planting, and establishment, including precise guidelines for excavation, plant pit preparation, planting techniques, watering, and a one-year plant establishment warranty period. The contractor must follow strict protocols for plant selection, handling, and installation, with multiple stages of inspection and approval by Forest Service ecologists. Payment will be structured with 75% paid after initial planting and the remaining 25% after final inspection and warranty implementation. The project emphasizes environmental preservation and native ecosystem restoration in the forest trail areas.

106 - Acceptance of Work 106.01_National_7_18_2017

Delete Subsection 106.01 and replace with the following:

106.01 Conformity with Contract Requirements.

Follow the requirements of FAR Clause 52.246-12 Inspection of Construction.

References to standard test methods of AASHTO, ASTM, GSA, and other recognized standard authorities refer to the methods in effect on the date of solicitation for bids.

Perform all work to the lines, grades, cross-sections, dimensions, and processes or material requirements shown on the plans or specified in the contract.

Incorporate manufactured materials into the work according to the manufacturer’s recommendations or to these specifications, whichever is more strict.

Plan dimensions and contract specification values are the values to be strived for and complied with as the design values from which any deviations are allowed. Perform work and provide material that is uniform in character and reasonably close to the prescribed value or within the specified tolerance range. The purpose of a tolerance range is to accommodate occasional minor variations from the median zone that are unavoidable for practical reasons.

When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, pipe conduits, etc., that are identified by gauge, unit mass, section dimensions, etc.), the identification will be considered to be nominal masses or dimensions. Unless specific contract tolerances are noted, established manufacturing tolerances will be accepted.

The Government may inspect, sample, or test all work at any time before final acceptance of the project. When the Government tests work, copies of test reports are furnished to the Contractor upon request. Government tests may or may not be performed at the work site. If Contractor testing and inspection is verified by the Government, the Contractor’s results may be used by the Government to evaluate work for acceptance. Do not rely on the availability of Government test results for process control.

Acceptable work conforming to the contract will be paid for at the contract unit bid price. Four methods of determining conformity and accepting work are described in Subsections 106.02 to 106.05 inclusive. The primary method of acceptance is specified in each Section of work. However, work may be rejected at any time it is found by any of the methods not to comply with the contract.

Remove, repair, or replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted. Removing, repairing, or replacing work; providing temporary traffic control; and any other related work to accomplish conformity will be at no cost to the Government.

(a) Disputing Government test results. If the accuracy of Government test results is disputed, promptly inform the CO. If the dispute is unresolved after reasonable steps are taken to resolve the dispute, further evaluation may be obtained by written request. Include a narrative describing the dispute and a proposed resolution protocol that addresses the following:

1. Sampling method;

2. Number of samples;

3. Sample transport;

4. Test procedures;

5. Testing laboratories;

6. Reporting;

7. Estimated time and costs; and

8. Validation process.

If the evaluation requires additional sampling or testing be performed, mutually agree with the Government on witnessing procedures and on sampling and testing by a third party laboratory. Use a third party laboratory accredited by the AASHTO accreditation program. Provide proof of the laboratory’s accreditation for the test procedures to be used. Do not use the same laboratory that produced the disputed Government test results or that produced the test results used as a basis for the dispute.

The CO will review the proposed resolution protocol and may modify it before final approval and execution.

The Government will use the approved resolution protocol test results to determine the validity of the disputed testing. If the Government test results are validated, the Contractor will be responsible for all costs associated with developing and performing the resolution protocol. If the Government test results are not validated, the

Government will be responsible for all costs associated with developing and performing the resolution protocol.

If the validity of the Government test results cannot be determined, the Contractor and Government will equally share all costs associated with developing and carrying out the resolution protocol.

(b) Alternatives to removing and replacing non-conforming work. As an alternative to removal and replacement, the Contractor may submit a written request to:

1. Have the work accepted at a reduced price; or

2. Be given permission to perform corrective measures to bring the work into conformity.

The request must contain supporting rationale and documentation. Include references or data justifying the proposal based on an evaluation of test results, effect on service life, value of material or work, quality, aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming work.

106.02_National_11_9_2016

Delete Subsection 106.02 and replace with the following:

106.02 Visual Inspection.

Acceptance is based on visual inspection of the work for compliance with the specific contract requirements. Use prevailing industry standards in the absence of specific contract requirements or tolerances.

Use required stake dimensions and materials. Pre-paint the top 2 inches of all stakes and lath, or mark them with plastic flagging. Use designated colors for paint or flagging. Mark all stakes with a stake pencil that leaves a legible imprint, or with waterproof ink.

Do not use aerosol spray paints.

Use moisture-resistant paper for survey notes. Keep notes in books with covers that will protect the contents and retain the pages in numerical sequence.

Make the following changes to Subsection 152.05:

152.05 Survey and Staking Requirements.

Delete Subsection 152.05(d)(2) and replace with the following:

(d) Slope and reference stakes.

(2) Conventional survey methods. When required, locate slope stakes on designated portions of the road. Locate the slope stake catch points and use them to establish clearing limits and slope stake references.

Mark slope stakes with the station, the amount of cut or fill, the horizontal distance to centerline, and the slope ratios.

Place slope reference stakes at least 10 feet outside the clearing limit and mark with the offset distance to the slope stake. Place sight stakes when required.

Prior to clearing and grubbing operations, move the slope stake outside the clearing limit to the slope reference stake. After clearing and grubbing and before excavation, reset the slope stakes in their original position.

Use the designated method to establish the slope stake catchpoint.

Method I—Computed Method. Use the template information shown in the plans or other

Government-provided data to calculate the actual location of the catchpoint. The slope stake

“catchpoint distance” provided may be used as a trial location to initiate slope staking. Recatch slope stakes on any section that does not match the staking report within the tolerances established in Table

152-2.

Method II—Catchpoint Measurement Method. Determine the location of slope stake catchpoints by measuring the catchpoint distances shown in the plans or other Government-provided data.

Add the following to Subsection 152.05(e):

(e) Clearing and grubbing limits.

Mark the clearing limits with flagging or tags on trees to be left standing, or on lath. Make markings intervisible, and no more than 90 feet apart.

After establishing clearing limits, move the location line stake outside the clearing limits for station identification purposes, and mark it with horizontal distance to location line.

Within twenty (20) days after award of contract, the contractor shall submit a written plan according to FP-14 subsection 104.03 with all necessary permits that provides permanent and temporary erosion control measures to minimize erosion and sedimentation during and after construction.

➢ The Soil Erosion and Sediment Control Plan shall provide specifics and specific locations which shall consists of furnishing, constructing, and maintaining soil erosion and sediment control devices to eliminate or minimize pollutants , stormwater discharges, and delivery of soil and turbidity into the stream from the project during the construction duration period.

➢ The Dewatering Structure(s) Plan shall provide specifics which shall consists of furnishing, constructing, and maintaining dewatering structures to eliminate or minimize pollutants , stormwater discharges, delivery of soil and turbidity and any cement, grout, concrete, and excavation material from getting into the stream from the project during the construction duration period.

• Plan shall include the sequence of operations and information on equipment, materials, suppliers, and location of each dewatering structure. Measures given in the Plans and Supplemental

Specifications are minimum requirements, and may be revised only with written approval by the

C.O..

• The turbidity of the water 100-200 feet downstream shall not be visually greater than the turbidity of the water upstream of the project site.

• When this turbidity requirement or other erosion control measures are not met, immediately take corrective action. Cease operations that are causing turbidity and pump the stream around the construction site according to this specification and the Plans until the turbidity requirement can be met. When the interpretation of this requirement is in question, measure turbidity using a turbidity meter as approved by the CO, and provide documentation that operations are in compliance with FAR 52.236-7 Permits and Responsibilities, FP-14 subsection 107.01 Laws to be Observed and subsection 107.10 Environmental Protection, and subsection 107.11, including but not limited to, the requirements of the National Marine Fisheries Service.

• Do not begin work until the necessary controls for that particular phase of work have been approved by the C.O. and implemented. Incorporate all erosion control features into the project at the earliest practicable time, as agreed by the CO.

• Operate in a manner that will avoid harm to aquatic organisms for the duration of the contract.

• Notify the CO of the intention of the placement of each dewatering structure with the date and time of placement of structure in reference to contract drawings. The contractor shall notify the

C.O. a minimum of at least 72 hours in advance (not including weekends and holidays).

• Do not re-route or remove the dewatering structure until approved by the CO. The CO will not approve dewatering until a fisheries biologist and other designated Government personnel are present and prepared to rescue aquatic organisms (AO). The contractor shall remove the dewatering structure slowly and incrementally in order to facilitate the AO rescue as applicable.

The rescue and inspection operations can generally take several hours.

Do not begin work until the necessary Soil Erosion and Sediment Control Plan and Dewatering Structure’s Plan has been approved by the C.O. and the controls for that particular phase of work have been implemented. Do not modify the type, size, or location of any control without C.O.’s approval.

When erosion control and dewatering measures are not functioning as intended, take corrective action to eliminate or minimize pollutants in storm water discharges from the project.

157.05 Controls and Limitation on Work.

Before grubbing or grading construct sediment controls around the perimeter of the project including filter barriers, diversion, and settling structures.

Construct and implement soil erosion and sediment control measures as follows:

(a) Construct temporary controls in incremental stages as construction proceeds;

(b) Construct temporary slope drains, diversion channels, and earth berms to protect disturbed areas and slopes. For the work immediately adjacent to the stream, use sediment control barriers between the work and the stream. Place sediment barriers prior to construction around sites where significant levels of erosion may enter the stream directly or through road or trail ditches.

(c) When a soil disturbing activity within a portion of the project is complete, apply permanent measures to the finished slopes and ditches within 14 days;

(d) Apply temporary turf establishment, mulch and stabilization measures on disturbed areas within three (3) days of the last disturbance. Short-term stabilization measures may include the use weed-free certified mulch, jute matting, and other similar techniques as approved by the C.O. . Short-term stabilization measures will be maintained until permanent erosion control measures are effective.

(e) Construct outlet protection as soon as culverts or other structures are complete;

(f) Construct and maintain soil erosion and sediment controls on and around soil stockpiles.

(g) Following each day’s grading operations, shape earthwork to minimize and control erosion from stormwater runoff; and

(h) Maintain stabilized construction exits to minimize tracking of soil onto existing roads.

Prior to construction, Contracting Officer will delineate critical riparian vegetation areas, wetlands, and other sensitive sites to prevent ground disturbance. Minimize disturbance to existing vegetation along stream.

Where necessary, hazard tree removal may be required by the Contracting Officer. When required, fell hazard trees within riparian areas when they pose a safety risk. Where possible, fell trees towards the stream. Keep felled trees on site when directed by the Contracting Officer.

Use existing roadways or travel paths. New access paths are not allowed unless written approval by the

Contracting Officer.

Conduct work activities during dry field conditions - low to moderate soil moisture levels.

Minimize clearing and grubbing activities when preparing staging, project, and or stockpile areas. Stockpile large wood, trees, vegetation, sand, topsoil and other excavated material, that are removed when establishing area(s) for site restoration.

Dispose of waste material in approved stable sites out of the flood prone area. Natural excessive waste material, other than hardened surface material (asphalt, concrete, etc), may be used as fill or to restore natural or near-natural contours.

When erosion control materials are to be left on site after the project has been completed, construct erosion controls of organic and bio-degradable materials whenever possible.

157.06 Filter Barriers.

Construct silt fence, berms, and fiber rolls and socks to reduce the velocity of runoff to allow sediment to settle.

157.07 Sediment Retention Structures.

Construct sediment retention structures of the following types.

(a) Temporary sediment traps. Construct temporary sediment traps to detain runoff from disturbed areas and settle out sediment. Provide outlet protection.

(b) Sediment basins. Construct sediment basins to store runoff and settle out sediment for large drainage areas. Excavate and construct sediment basins according to FP-14 Section 204. Construct riser pipes according to FP-14 Section 602. Provide outlet protection

157.08 Outlet Protection.

Construct riprap aprons or basins to reduce water velocity and prevent scour at the outlet of permanent and temporary erosion and sediment control measures. Construct riprap according to FP-14 Section 251.

157.09 Water Crossings.

Construct temporary culvert pipe at temporary crossings where construction vehicles cross a live waterway.

Approval by C.O. is required before installation of temporary structures may commence.

157.10 Diversions.

Construct temporary channels, temporary culverts, or sandbags to divert water around disturbed areas and slopes.

Use temporary channels, temporary culverts, pumps, sandbags, or other methods to divert the flow of live streams for permanent culvert installations and other work. Stabilize channels according to FP-14 Subsection 157.11.

Provide outlet protection.

Construct stream diversion, related appurtenances and measures as follows:

(a) In Stream Work.

(1) Isolate construction area and coordinate with Contracting Officer to have any aquatic species removed from the construction area by the Government. Coordinate aquatic species removal with the Contracting Officer a minimum of 10 working days prior to beginning isolation of construction areas.

(2) Cease project operations under high flow conditions that inundate the project area, except for efforts to avoid or minimize resource damage.

(3) C.O.’s approval is required in writing prior for any equipment that may require to be in the stream.

If approved by the C.O., the contractor shall minimize time in which heavy equipment is in stream channels, riparian areas, and wetlands. Operate heavy equipment in streams only when Contracting

Officer determines that such actions are the only reasonable alternative for implementation, or would result in less sediment in the stream channel or damage (short- or long-term) to the overall aquatic and riparian ecosystem relative to other alternatives.

(4) Clean and repair all equipment used for in stream work prior to entering the project area. Remove external oil and grease, along with dirt and mud prior to construction. Inspect equipment daily for leaks or accumulations of grease, and fix any identified problems before entering streams or areas that drain directly to streams or wetlands.

(5) Fuel and service equipment used for in stream or riparian work in an approved staging area outside of riparian zone. When not in use, store vehicles in the staging area.

(b) Temporary Stream Bypass Dam.

Construct a temporary stream bypass dam using the following approved methods

(1) Sandbag dam

(2) Temporary cofferdams shall conform to the requirement of FP-14 Section 208.05. Shoring systems and cofferdams require the Contractor to submit cofferdam dam drawings in relation to this construction project showing proposed methods and construction details of cofferdams according to

FP-14 Subsection 104.03 and Section 562. Cofferdam drawings shall bear the seal and signature of a Professional Engineer (P.E.) engineer proficient in the pertinent design field)

(3) Temporary sheet pile (temporary sheet pile(s) shall conform to AASHTO M 202 or ASTM A572)

(4) The mining of material from the streambed or floodplain to construct diversions is not permitted. If diversion allows for downstream aquatic species passage, (i.e., is not screened), place diversion outlet in a location to promote safe reentry of aquatic species into the stream channel, preferably into pool habitat with cover.

(5) Primary Bypass Dam. Construct the Sandbag Dam in a dry condition by first pumping the stream around the dam. Place temporary cofferdams as needed. Remove irregularities from the streambed to form smooth bedding for the bypass dam. Place the dam so that water does not seep from the downstream side of the dam; if seepage occurs, improve the dam by adding sandbags, improving or adding seals, or other means to minimize seepage from the dam. When it is impossible to eliminate seepage, construct a sump and pump clear water to the upstream side of the dam.

(6) Bypass pipe. Place bypass pipe as shown on the Plans or approved by the CO. Place the upstream invert of the pipe at the lowest point in the stream channel as practical. Install joints and elbows as shown on the Plans and as needed to accommodate the site layout. Use watertight seals meeting the requirements of Subsection 712.03. Do not place backfill until the pipe joints have been approved by the CO. Allow water to pass through pipe only after a downstream splash apron has been prepared in a manner that will protect the stream from scour and turbidity, and protect fish from harm. Construct the bypass in a manner that avoids injury to aquatic organisms.

(7) Downstream Dam. When water flows into the work area from downstream, construct a cofferdam as needed to prevent water from entering the work area.

(8) Sandbags. Prior to placing the lower rows of sandbags, remove the larger rocks or other irregularities from the streambed to form a smooth bed. Use only clean sand or coarse concrete aggregate in the sandbags. Loosely fill and tamp the sandbags in place to minimize seepage between, under, and around the bags.

(9) Bypass Pipe Collar. Install and maintain a leak-proof pipe collar as shown on the Plans or approved by the CO.

(c) Pumps.

Install pumps as required to re-route stream around construction site and dewater foundations. When failure of a pump would result in movement of sediment or turbidity beyond the work area, provide a back-up pump that is readily available. Use the pumps for installing and removing the gravity bypass pipes and dams, at other times to facilitate construction operations, and during storms to supplement the gravity bypass. Pumps must have fish screens and be operated in accordance with NMFS aquatic species screen criteria. Equip the pump with approved fish screens, appropriate suction and discharge hoses, fittings and flow regulation equipment as needed. Insure that the pumps are clean, free of leaks and that the oil used as lubricant in the pump seal systems is food grade mineral oil. Install and operate pumps in a manner that will avoid impingement of small fish against the intake screens.

(1) Pump intakes. Use one of the following methods of screening on all draft hoses:

i. Perforated Plate; screen openings shall not exceed 3/32 or 0.0938-inches

ii. Profile Bar Screen; the narrowest dimension in the screen openings shall not exceed

0.0689-inches in the narrowest direction.

iii. Woven Wire Screen; screen openings shall not exceed 3/32 or 0.0938-inches the narrow direction.

Check intakes frequently and clean as needed with wire brushing, flushing, or any other acceptable method.

(2) Sump Pumps. Supply pumps capable of dewatering the structure foundation. Insure that pumps are clean and free of leaks. Remove sediment and turbidity in the Sump Pump discharge water prior to re-entering the stream.

(d) Sump Water Discharge.

Discharge sump water as shown on the Plan or as approved by the CO. Apply one or more methods to remove sediment from sediment-laden water. Apply additional methods as needed to eliminate increase in downstream turbidity. Use the following methods as needed:

(1) Natural Vegetation/Soil Dispersal and Filtration. Discharge sump water onto areas of ground most advantageous for dispersal and filtration of sediment, e.g. flat heavily vegetated soil. When single point discharge does not function adequately, discharge water into a perforated pipe or series of pipes laid approximately level so that the brown water disperses over a wide area.

(2) Silt Bag Filtration. Discharge sump water into one or more Silt Bags. Silt Bags are constructed of

Mirafi 180N (or approved equal) with sewn seam strengths of 90% efficiency according to ASTM

D4632. Construct bag to hold and filter sump water. Place silt bag(s) on level ground having layer of straw one foot thick minimum.

(3) Settling Basin. Discharge sump water into one or more Basins. The Basins may be pre-manufactured tanks, folding tanks, geotextile or membranes placed over a sandbag or weed-free straw berm, or other similar basins designed to separate sediment from the water.

(4) Suspended Sediment Coagulation Agent. When other methods do not function adequately, add an approved coagulation agent to water prior to discharging the water onto natural vegetation, Silt

Bag, or Settling Basin. Use a flocculation agent such as Chitisan-based Storm-Klear Gel-Floc, or approved equal. Use Suspended Sediment Coagulation Agent according to manufacturer’s recommendations.

(e) Sedimats.

Place Sedimats across the streambed as shown on the Plans or approved by the CO. The Sedimat is a proprietary product manufactured by Indian Valley Industries, Inc. and distributed by Columbia Storage

Inc., Vancouver Washington, phone: (800) 426-7976. Use Sedimats according to manufacturer’s recommendations.

(f) Stream Re-Watering.

Monitor downstream during rewatering to prevent stranding of aquatic organisms below the construction site. Ensure that concrete is sufficiently cured or dried before coming into contact with stream flow.

157.11 Waterway and Slope Protection and Stabilization.

Use the following:

(a) Plastic lining. Use plastic lining to protect underlying soil from erosion. Place the plastic lining loosely on a smooth soil surface free of projections or depressions…
