BASE – Greek Creek Campground, Swan Creek Road and Campground, Moose Creek Campground, and Spanish Creek Road

Additive #1 – Storm Castle Road

C-1 – PROJECT DESCRIPTION AND LOCATION

(a) Scope of Contract Work will consist of bituminous surface treatment and aggregate placement (chip sealing) on existing paved roads, campgrounds, turnouts. Work will also include crack sealing and asphalt pavement patching The contractor shall furnish all labor, equipment, transportation, supervision, operating supplies, materials and incidentals necessary to complete the project as awarded. All work and equipment shall be in compliance with the terms, specifications, and provisions of this contract. All equipment shall be in good mechanical operating condition, fully capable of performing all phases of work as required, and shall be operated by competent, qualified operators experienced in the work.

(b) Project Location The project is located approx. 18 miles south of Gallatin Gateway, MT on the Bozeman Ranger District of the Gallatin National Forest, See attached plans for detailed project location(s).

(c) Start of Work/Period of Performance It is estimated that the work can begin 2021. Application of oil and chips shall be restricted to a period between June 15, 2020 and August 31, 2020. The contractor shall be required to: 1) Commence work under this contract within 10 calendar days after the Notice to Proceed is received, 2) Prosecute the work diligently, and 3) Complete the entire project, ready for use, no later than July 31, 2022.

(d) Submittals Fourteen (14) days prior to start of work contractor shall submit Traffic Control Plan and furnish Manufacturers Certificates and Data certifying that the following materials conform to the requirements specified: CRS-2P, Aggregate (chips), Pavement Repair sections (hot mix asphalt design).

(e) Pre-bid Tour No formal site tour is planned; however, bidders are strongly encouraged to visit the sites prior to preparing and submitting their bid. Directional information may be had by contacting Grant Morrison, Custer Gallatin National Forest Supervisors Office, Bozeman, Montana, telephone (406)587-6724.

C-2 – GENERAL SPECIFICATIONS

(a) Traffic Control Roads will remain open at all times, with 20 minute delays to public traffic allowed, single-lane two way traffic with flagger control is acceptable.

Campground loops may be closed for up to four (4) hours continuous hours followed by a minimum one (1) hour open period. Contractor shall provide notification 7 days prior to anticipated campground closures. Work on approaches to the public highway may require lane closures on highway, contractor shall coordinate with MDOT for this work. Appropriate signing, flaggers, and/or pilot car will be required. The contractor shall provide, erect, and maintain all necessary barricades, suitable and sufficient lights, danger signals, signs, and other traffic control devices, and shall take all necessary precautions for the protection of the work and safety of the public. Suitable warning signs shall be provided to properly control and direct traffic. The contractor shall erect warning signs in advance to any place on the project where operations may interfere with the use of the road by traffic. All devices, flaggers, and pilot car operations shall conform to Part VI of the Manual on Uniform Traffic Control Devices for Streets and Highways, published by the Federal Highway Administration, and applicable safety codes.

(b) Protection of Existing Structures Kiosks, islands, outhouses, guard rails, and other structures adjacent to the project will be protected from damage and/or overspray by approved methods.

(c) Surface Preparation The Contractor shall be responsible for all measures required to provide a thoroughly clean and dry pavement surface, including vegetation removal and sweeping prior to the Chip Seal application and the following Striping application. The Contractor should observe the pavement conditions prior to bidding to determine the work necessary to provide such a surface for successful project completion and shall include the work necessary in the bid. Surface preparation is incidental to chip sealing and striping.

(d) Final Clean-up – Remove all debris, rubbish, and excess material from the project and off Forest Lands.

C-3 – PROJECT REQUIREMENTS

Chip Seal* Equipment – The size and condition of all equipment shall be sufficient to meet the job requirements and successfully complete the project.

A. Distributor – Self-powered and capable of providing a uniform application rate of emulsion with an adjustable, full circulation spray bar.

B. Power Broom – Self-propelled and capable of controlling the vertical broom pressure.

C. Aggregate Spreader – Self-propelled with a minimum of 4 pneumatic tires on two axles. Equipped with positive controls capable of providing a uniform application rate of aggregate over a variable width in a single pass.

D. Rollers – Furnish two pneumatic tire rollers that are self-propelled with a minimum compacting width of 5 feet for seating the chip seal. They will have a gross load adjustable to apply 280 pounds (+ or minus 25%) of pressure per inch of rolling width. Compaction speed shall be less than 5 mph at all times.

Execution A. Surface Preparation – See above section C-2 part c.

B. Application of Bituminous Materials – Application of the emulsion shall be performed by means of a pressure distributor to achieve a uniform and continuous spread over the asphalt surface. The quantity per square yard shall be as determined by the control test strip(s) completed on day one. At no time shall the emulsion be allowed to break, chill, set-up, harden, or otherwise impair the aggregate retention before the aggregate has been properly applied and rolled.

C. Application of Aggregate – The aggregate shall be applied immediately following the emulsion application. The quantity of cover coat aggregate per square yard shall be as determined by the control strip(s) completed on day one.

D. Rolling – Initial rolling shall begin immediately after application of the cover coat aggregate, with the rollers working in tandem. Sufficiently roll the surface to uniformly and thoroughly bind the aggregate over the full width. Complete rolling within one hour after the asphalt is applied to the surface.

E. Sweeping – Sweep excess material from the surface by lightly brooming the aggregate surface on the morning after construction when the temperature is less than 75°F. Do not displace embedded material.

F. Weather Limitations – The chip seal shall not be applied when the pavement is moist, or when the weather is, or may be, detrimental. Detrimental weather is defined as rain showers, cool temperatures, moist pavements, threat of rain showers, or other environmental factors which could affect the performance of the chip seal construction. If either the air or pavement temperature is below 60°F and falling, do not apply the chip seal. The chip seal may be applied when both pavement and air temperatures are above 60°F and rising.

Asphalt Concrete Pavement Patching The old asphalt pavement will be removed off of Forest Service land and disposed of properly.

Traffic Management and Control A. See C-2, part(a) above

B. A traffic control plan approved by the C.O.R. will be required before any work commences.
