Grand Canyon National Park Inner Canyon Bunkhouse Code of Conduct

Work The primary purpose for Inner Canyon bunkhouse use is to facilitate the completion of NPS work projects. These are NOT party trips and events. We expect all workers and participants to be fully engaged and actively participate in all required duties for the duration of each trip. This includes shared activities: loading and unloading, cooking, doing dishes, keeping facilities clean, and completing final facility cleaning prior to departure.

Cooperation Bunkhouse users often consist of employees from different divisions, NPS contractors, and volunteers.

Rangers are expected to walk through the bunkhouse to check fire and safety equipment, look for emergent issues (broken pipes, running water, fire hazards, etc.) and check security. Establishing good working relationships is essential in shared quarters and requires full cooperation from everyone. Do your part to keep the bunkhouse clean. People may be working difference work schedules, so maintaining quiet hours and respect for the sleep of others is mandatory!

Quiet Hours There are park visitors camping nearby and other residents in close proximity. At these locations, voices and noise carries and echoes, and we do not want to impact the experience of others. Many campers are exhausted and go to sleep at dark. Quiet hours must be observed at these facilities from 8pm to 6am.

However, noise can be unreasonable at any time of day, when other people are disturbed through inconsiderate or reckless behavior. If there is any non-adherence to these rules, you may be contacted by a Law Enforcement Ranger.

Especially at Indian Garden, sound travels directly from the bunkhouse to the campground. At night, conversation and laughter outside the bunkhouse (or inside, with the windows open) is disruptive to campers trying to sleep. If you want to socialize after dark, do so inside the IG bunkhouse with the windows closed, or hike out toward Plateau Point.

Professionalism, Rules, Alcohol and Drug Policy NPS rules and regulations will be adhered to at all times. The use of alcohol in the Inner Canyon Bunkhouses, campgrounds and overflow areas is prohibited during or after work hours. Likewise, transport of alcohol by NPS on-duty staff or livestock is prohibited. Illegal drugs are against the law and will not be tolerated. Federal drug laws apply. We expect everyone to be professionals at all times.

Noncompliance with rules or regulations may result in the offender being expelled from temporary backcountry quarters and/or revocation of privileges to use bunkhouses by the offending program/division.

Dark Skies Grand Canyon National Park is conserving our Dark Skies. Please do your part by closing the blinds on all bunkhouse windows after dark.

Rodents All of the Inner Canyon Bunkhouses are prone to mouse infestations. Please keep the door closed except when walking in or out of the bunkhouse. Maintain good housekeeping measures…sweep floors and wipe counters after each and every meal preparation. Store food properly (rodent proof containers) when not in use (no leftover sandwiches and trail mix in your backpack on the floor overnight, etc.) If you see

GRCA - 229035 01 11 00 SUPPLEMENT - 2

mice (or mouse sign) in the bunkhouse, please follow the Integrated Pest Management notification procedure.

Positive Attitude Maintain a positive attitude, be flexible, patient, and open to learning from others. The way you interact with others and with the group as a whole has an impact on the work and the reputation of your particular crew, so please be positive and professional.

Inner Canyon Bunkhouse

During your project work, you have been allowed to stay at one of the NPS bunkhouses. Please make sure you meet with your NPS project manager prior to heading into the canyon to ensure you have a key for the facility.

The bunkhouses are shared quarters and there may be other users while you are there.

Each bunkhouse has bunkbeds, full kitchen, sitting area, bathrooms with showers, and access to laundry facilities. There are some linens, blankets, and towels. Many guests opt to bring their own.

There may be other concerns that may influence your stay including requirements during public health emergencies or infrastructure concerns.

As of April 2021, the park is still taking COVID-19 precautions. Masks are required when inside buildings and in outdoor areas where distancing is not possible. Up to date information can be found at https://www.nps.gov/grca/planyourvisit/conditions.htm. Please coordinate use of the kitchen and bathrooms with other users. Remember to wash your hands and wipe down surfaces.

The Phantom Waste Water Treatment plant has been overtaxed by the amount of waste.

Please be very conscientious with any waste water going down the drain. The NPS has significantly reduced the use of the backcountry campground and the Phantom Ranch guests to reduce the load. Please take short showers and limit the amount of laundry.

Please help us take care of the park and these facilities.

Cleaning Checklist It is the responsibility of everyone who occupies a bunkhouse to ensure that it is kept clean.

Prior to vacating, the facility must be cleaned to the standards supplied below.

If supplies or repairs are needed please notify your NPS project manager. They will submit the appropriate requests.

Should be stocked at all times: Toilet Paper, Dish Soap, Laundry Soap, Simple Green, Mops, Brooms, Vacuum, Linens, Pillows, Blankets, Cookware, Flatware, Dishes and Mouse traps.

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 failure of 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 that they are included in the hourly rate shown, or contractor is not requesting reimbursement.

Contractor may utilize the government provided Contractor Estimate Form, or their own form, provided that it contains the same information and level of detail as the Gov’t provided form.

3. Requests for extensions of contract time as a result of this change must be justified with a Time Impact Analysis (TIA). Refer to Division 01 Specification, “Construction

GRCA - 229035 01 26 01 - 4

Schedule”, for time impact analysis requirements. TIA and associated costs must be received with the proposal by the date shown within the Request for Proposal letter.

Contractor’s failure to submit within the specified time frame will be construed as the Contractor waiving the right for additional time and no time extension will be allowed.

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

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

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

B. Labor:

1. 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 in accordance with 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 $500 or less. Costs shown in excess of $500 must be broken out separately.

a. U.S. Army Corps of Engineers , Ownership and Operating Expense Schedule (use 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 equipment rates shall include the operating costs of all fuel, oil, lubrication, supplies, small tools, necessary attachments, ground engaging components, tires & tracks, routine repairs and maintenance (cost of major repair and overhaul is not allowed per FAR 31.105(d)(2)), 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 in accordance with 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 ½ of the equipment costs minus any operating costs, major repair and overhaul will be accepted.

7. If 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.

8. Equipment that is not used and on the jobsite 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 jobsite 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 FAR Part 31which have been applied to the specific type of work included in this project. Negotiated rates shall not exceed the following percentages for OH&P for contractor self-performed work:

Overhead………………10% Profit……………………10%

2. Total aggregate limit of markup (OH&P) for contractor and subcontractors on modification work shall not exceed 25%. The NPS will not be responsible for allocation of percentages between contractor and subcontractors at any tier.

3. If contractors form a partnership, than 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.
