1.3 CONTRACTOR USE OF SITE

OLYM – 306966 & 307067 01 11 00 - 3

A. General: Contractor shall have limited use of site for construction operations. Limit use of premises to areas within the construction limits indicated on drawings. Do not disturb portions of Project site beyond areas in which the Work is indicated.

1. Contractor may request to use the far west end of the main Hurricane Ridge parking lot for staging of equipment and materials. Any request must consider and ensure adequate space remains for safe turnaround of large vehicles including buses and Recreational Vehicles (RVs), and full lane widths are available for through-traffic to Hurricane Hill.

2. Contractor may request to use the original Visitor Center / Day Lodge site for staging of equipment and materials. Any request to use this site shall include a description of the route and any improvements or modifications required for access from the main parking lot.

B. Site Access: Contractor shall access the project site via Hurricane Ridge Road, which requires passing through the NPS Heart O’ the Hills Entrance Station. Entrance fees will be waived for Contractor and all subcontractors and suppliers directly supporting the project during the period of performance.

1. Access from the main parking area to the reservoir for vehicles and equipment is generally possible via the asphalted High Ridge Trail. Note that the paved width of this trail is approximately 5-6 feet. Impacts to the trail and trail shoulders resulting from vehicle and equipment access shall be restored to pre-construction conditions.

C. Construction Time Period: Timing of work shall be coordinated with the Contracting Officer and follow the approved Contractor’s work schedule.

1. Target start date of project is May 5, 2025; onsite work may start earlier if seasonal snow conditions allow access. Note that NPS does not generally perform snow removal operations at Hurricane Ridge during the month of April. Late season snow storms may require NPS to close Hurricane Ridge Road to public access at Heart O’ the Hills Campground. Contractor will be allowed to access the project site but must self-perform any additional snow removal required for construction activities during the month of April.

2. Target opening date of Hurricane Hill Road (extension of Hurricane Ridge Road from main parking area to Hurricane Hill Trailhead) is Memorial Day weekend. NPS generally performs snow removal along the road corridor during the month of May to provide holiday weekend access to the public. The NPS snow removal corridor will generally extend no more than one foot beyond the edge of pavement. Contractor may request that Hurricane Hill Road remain closed to public access during weekdays (Monday – Thursday) for up to four weeks after Memorial Day weekend to facilitate rapid replacement of water line to comfort stations.

3. Contractor may request partial closures of parking areas within the main Hurricane Ridge parking lot for installation of new water line, or to provide access for equipment and materials. In general, no more than 200 lineal feet of parking area may be closed for construction at a time. Requests for partial closures of parking areas between mid-July and Labor Day will only be approved when absolutely necessary and must be kept to the minimum size and duration to complete the work.

4. If the contract option is exercised, demolition work associated with removal of the concrete intake dams shall be completed between August 1, 2025 and Labor Day (i.e., the driest time of the year) to minimize negative impacts to plant and wildlife species.

D. Staging and Storage of Materials: Confine storage of equipment and materials to the staging/lay-down/storage areas identified within the area designated by the Contracting Officer or as established at the preconstruction meeting. To minimize the amount of ground disturbance, staging and stockpiling areas shall be located in previously disturbed sites, away from visitor use areas to the greatest extent possible. All staging and stockpiling areas shall be returned to pre-construction conditions following construction.

1. To minimize impacts to vegetation surrounding the water storage reservoir, soil cover shall be excavated from one half of the storage tank lid and stockpiled on the other half during cleaning and surface sealing up to and including the seam between lid and sidewall, then vice versa for the other half until the entire water storage reservoir lid and seams have been cleaned and sealed.

E. Vehicles & Equipment: Confine parking to areas designated for parking or staging of materials and equipment.

1. No unattended motors/engines are permitted. No idling of motors or engines for extended periods of time is permitted.

2. Fueling of any type, whether equipment or vehicles, must be done either on non-pervious surfaces such as concrete or asphalt, or deploy a spill containment pad.

3. Equipment must be free of any fluid leaks (fuel, oil, hydraulic fluid, etc.) upon arrival to the work site and will be inspected at the beginning of each shift for leaks. Leaking equipment will be removed off site for necessary repairs before the commencement of work.

F. Preservation of Natural Features:

1. Re-use fill, rock, or topsoil from the project area, if possible. If not possible, then the

Contractor shall submit a list of proposed sources, end-use, and temporary storage requirements for imported material, 30 calendar days before delivery. The sources of imported rock, sand, gravel, and soil shall be inspected for invasive non-native plants, weeds, and/or seeds. The material must not be stockpiled at the quarry for more than 1 week after washing. If material comes from older stockpiles, the quarry must be certified weed-free by the County Noxious Weed Coordinator or a qualified weed inspector designated by NPS. For details on obtaining pit inspections and topsoil specifications, contact Contracting Officer’s Representative (COR) and provide at least 14 days notice that an inspection is needed. Imported material shall be free of non-native weeds and/or seeds. Imported material shall be shipped directly from the source to the Park without intermediary storage or staging.

2. Prevent damage to natural surroundings. Restore damaged areas, repairing or replacing damaged trees and plants, at no additional expense to the Government.

3. Provide temporary barriers to protect existing trees and plants and root zones.

4. Do not remove, injure, or destroy trees or other plants without prior approval. Consult with Contracting Officer’s Representative (COR) and remove agreed-on roots, branches, and small trees that interfere with construction.

5. Do not fasten ropes, cables, or guys to existing trees.

6. Carefully supervise excavating, grading, filling, and other construction operations near trees to prevent damage. Where utility excavation or trenching intersects root systems of larger trees, cut roots greater than 3 inches in diameter cleanly with a sharp tool such as a saw (i.e. do not tear with the excavator).

7. Erosion control measures shall follow the approved UPPP.

OLYM – 306966 & 307067 01 11 00 - 5

8. Care shall be taken not to disturb any wildlife species (marmots, mountain beavers, reptiles, migratory birds, raptors, or bats) found nesting, hibernating, estivating, or otherwise living in, or immediately nearby, worksites.

9. All disturbed ground shall be reclaimed using appropriate best management practices, which may include planting or seeding with native vegetation, or, in the case of small treatment areas, allowing native vegetation to reclaim the area naturally. Contractor shall consult with Contracting Officer’s Representative to determine the best methods for restoration.

10. Where trenching for water line installation or replacment traverses native subalpine meadow vegetation, Contractor shall be responsible for removal, preservation, and replacement of vegetation in the form of “sheets”, “mats”, “plugs”, or similar. Vegetation within the trench cut shall be removed in the largest contiguous sheets possible, with a target depth/thickness of 6-8”, and set aside (orientation: vegetation up, roots down) until native vegetation sheets can be replaced following installation of new water line.

Vegetation sheets can be stockpiled or staged directly on top of existing vegetation if not left for longer than 72 hours. Contractor shall be responsible for watering vegetation sheets to maintain adequate moisture if vegetation sheets are outside the trench for longer than 72 hours without measurable precipitation. Contractor shall be responsible for watering subalpine meadow vegetation sheets to the point of saturation (i.e., when soil reaches its maximum capacity to hold water, and excess water begins to drain away from the root zone) within 24 hours of re-establishing native vegetation in the trench following backfill and compaction.

11. All native subalpine meadow vegetation removed and replaced within the utility corridor (i.e., from the reservoir to the main parking area) shall be watered to the point of saturation one final time between the dates of September 15 and October 1, 2025, regardless of the actual date when the work of this contract is substantially complete.

G. Driveways and Entrances: Keep driveways, areas specifically designated by the Contracting

Officer, and entrances serving premises clear and available to Government, Government employees, user groups, and emergency vehicles at all times. Do not use these areas for parking or storage of materials.

1. Schedule deliveries to minimize the use of driveways and entrances.

2. Schedule deliveries to minimize space and time requirements for the storage of materials and equipment on-site.

H. Construction Camp: The establishment of a camp within the Park is not permitted.

I. Hauling Restrictions: Comply with legal load restrictions in hauling of materials. Load restrictions on park roads are identical to state load restrictions with such additional regulations as may be imposed by the Park Superintendent. Information regarding rules and regulations for vehicular traffic on park roads may be obtained from the Office of the Park Superintendent. A special permit will not relieve Contractor of liability for damage which may result from moving of equipment

J. All work is restricted to the pre-approved construction area. No impacts to areas outside of the construction area shall occur.

K. There shall be no in-water work. Any work involving demolition of intake dams associated with abandoned surface water infrastructure will require dewatering and/or stream diversion to avoid working in water.

1.3 MODIFICATION PROPOSAL PRICING REQUIREMENTS

A. General:

1. Your proposal must be received in the format and within the time frame specified in the

Request for Proposal letter. Costs or delays resulting from the failure of the contractor to submit within the time frame specified will not be compensable.

2. The proposal must be detailed with itemized lists of equipment, materials, labor, production rates, overhead, profit, and bond markup for each item. Labor costs must be itemized by craft and hourly rate, including Fringe Benefits and Labor, Burden. If the costs of Fringe Benefits and Labor Burden are not itemized, it is assumed that they are included in the hourly rate shown, or the contractor is not requesting reimbursement.

The contractor may utilize the government-provided Contractor Estimate Form or their form, provided that it contains comparable information as the Government-provided form and is acceptable to the Contracting Officer.

3. All supporting documentation used to justify the proposed modification will be made available to the Contracting Officer upon request.

4. The contractor must review and approve all subcontractor/supplier pricing in detail for proper format, scope, production rates, and pricing before submission to the NPS. All delay costs associated with not reviewing and approving subcontractor/supplier pricing will be borne by the Contractor.

5. All pricing and production rates within the estimate must be based on fair and reasonable pricing and cannot include a built-in contingency.

B. Labor:

1. The contractor shall estimate the cost of labor by itemizing each craft involved, indicating worker hourly rate (base rate + labor burden + fringe benefits) for each, and itemizing the hours required for each craft that will be directly engaged in modification work. Any work proposed that will require overtime work or premium pay shall be itemized separately. All rates shall be following the Davis-Bacon Act as incorporated herein. Labor Burden may include payroll taxes, Social Security, unemployment insurances, workers compensation insurance, FICA, FUTA, and other direct costs resulting from Federal, State, or local laws.

2. Itemize labor costs for equipment operators separate from equipment costs.

3. The labor cost for foremen shall only be costs for related work required for the modification.

C. Materials:

1. The estimated cost for materials shall include quotes from multiple sources. Material prices must include all applicable fees and credits, including but not limited to, sales tax, freight and delivery charges, and tax rebates.

2. No markup shall be applied to any material provided by the NPS.

D. Equipment:

1. Equipment used for the project must be appropriately sized for the work being performed.

2. Do not include costs for “miscellaneous tools and equipment”, in your proposal for a replacement value of five hundred dollars ($500) or less. Costs shown over five hundred dollars ($500) must be broken out separately.

3. Regardless of ownership, the rates to be used in determining equipment rental costs shall be the lowest cost from one of the following sources:

a. U.S. Army Corps of Engineers, Ownership and Operating Expense Schedule (use the latest edition and applicable region)

b. Construction Blue Book

c. Local equipment rental rates, documented by actual invoice charges, or itemized vendor quotes.

4. The estimated rental rates shall include the cost of all fuel, oil, lubrication, supplies, small tools, necessary attachments, ground engaging components, tires & tracks, routine repairs and maintenance (cost of a major overhaul is not included), depreciation, storage, insurance, and all incidentals. Mobilization, if applicable, may be included for equipment solely used on the modification work but must be listed separately.

5. Estimate the full rate for equipment only for the duration that the equipment will be utilized to accomplish the work of the modification.

6. Standby unit rates used are to be following paragraph 1.3, D, 2, above. If the US Army Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then one-half (½) of the equipment costs minus any operating costs will be accepted.

7. If the equipment is in standby mode due solely to a documented NPS delay, the established standby rate shall apply from the first day of the delay.

OLYM – 306966 & 307067 01 26 00 - 5

8. Equipment that is not used and on the job site for up to five consecutive days may be classified at standby rates, provided that the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work.

Equipment that is still on the job site but not in use after five consecutive days will not be considered in the modification pricing.

9. Requests for compensation for equipment stand-by time must be justified, documented, and itemized separately.

10. The estimated timeframe (daily, weekly, monthly) for use of the equipment must reflect the lowest cost to the Government.

E. Establishment and Application of Overhead and Profit Percentages:

1. Home Office Overhead and Profit (OH&P) shall be applied to direct costs only. Profit shall not be applied to overhead amounts, and overhead shall not be applied to profit. Home office overhead shall contain only allowable, allocable, and reasonable costs per the contract documents and FAR Part 31. Profit percentages are based on risk factors found in the FAR Part 31which have been applied to the specific type of work included in this project. The following percentages establish the maximum allowable markups (OH&P) for contractor self-performed work:

Overhead………………10% Profit…………………..12%

2. The total aggregate limit of markup (OH&P) for contractors and subcontractors on modification work shall not exceed twenty-five percent (25%). The NPS will not be responsible for the allocation of percentages between contractors and subcontractors at any tier.

3. If contractors form a partnership, then the partnership may only receive home office overhead and profit in the same amount as an individual contractor (refer to par 1.3, E,1 above). It is the responsibility of the partners to decide on the division of revenue.

4. Combined Increases and Decreases: On proposals involving both increases and decreases in the Contract Price, the overhead and profit mark-ups are required on the net increases and deducted on net decreases.

5. At no time can profit be calculated on Overhead or itself, it must be calculated on direct costs of work only.
