Fabric Shelter Preventative Maintenance and Repair Services 30 September 2021

1.0. Description of Services. The contractor shall provide all parts, tools, equipment, transportation, personnel, labor, supervision, and management to perform preventative maintenance (PM), cleaning, and repair services on Fabric Shelters located in area 30 on the 309 AMARG complex, at Davis-Monthan Air Force Base (DMAFB), AZ.

1.1. Preventive Maintenance (PM). The contractor shall perform on-site scheduled PM for all the fabric shelters located at AMARG, in accordance with industry standards and equipment manufacturers’ recommendations as follows:

Fabric Shelter Shelter Maintenance Tension Fabric Shelter— Large 140' x 325' fabric structures Quonset Style shelters

Semi-annual preventative maintenance - every 6 months:

Cover fabric tensioning, tension ratchets, and straps (If the structure is subject to unusually high winds and heat exposure, more frequent tightening may be required at the discretion of the AMARG POC)

Tension Fabric Shelter— Small 78' X 320' fabric structures Quonset Style shelters

Semi-annual Preventative maintenance - every 6 months:

Tension ratchets, straps, frame components (nuts and bolts).

(If the structure is subjected to unusually high winds and heat exposure, more frequent tightening may be required at the discretion of the AMARG POC)

1.1.1. Preventive Maintenance Inspection (PMI) Plan. The contractor shall develop and maintain a PMI plan that includes all of the required inspections and repairs per the requirements listed in the PWS, for all fabric shelter listed in Appendix 1. The contractor shall submit the PMI plan to the Contracting Officer and the designated AMARG POC for acceptance, no later than fourteen (14) workdays after the contract start date. Any updates to the PMI Plan should be provided to the designated AMARG POC and the CO for approval.

1.1.2. Preventive Maintenance (PM) Schedule. The contractor shall develop and submit a PM schedule for all fabric shelters listed in Appendix 1. The plan shall provide fabric shelter numbers (Appendix 1) to be serviced two (2) times a year as required per the PWS. The schedule shall reflect the days of the week when PM services will be performed. The contractor shall submit the schedule, and any subsequent changes, to the AMARG POC for acceptance, no later than five (5) workdays after contract start date. The contractor may increase the frequency of preventive maintenance, in an effort to minimize repair requirements, at the contractor’s discretion and at no additional cost to the Government. If at any time the contractor is unable to follow the schedule, the contractor shall notify a designated AMARG POC.

2.0. Preventative Maintenance Requirements as follows:

2.1. Cover Fabric Tensioning. Proper tension is achieved by tensioning the ratchets connected over the arched end trusses first. After the cover has been tensioned evenly from front to back, the ratchets along the sides should be tensioned evenly.

2.1.1. Tension Ratchets. Make sure that ratchets are tightened evenly and that the ratchet handles are in the locked position. When ratchets are tensioned properly, the covers should be free of wrinkles and the tension tubes will be straight. If any of the tension tubes show deflection, adjust the tension of the ratchets so that tubes are straight. Any broken or frayed/torn ratchet straps will be replaced immediately.

2.1.2. Straps. Inspect fabric straps to make sure that none of them are damaged or loose. Any loose fabric straps will be tightened and any broken or frayed/torn tension straps will be replaced immediately.

2.1.3. Bracing Inspection. Inspect each wind bracing cable for signs of chafing or wear.

Damaged cable should be replaced. Check each turnbuckle for proper tension and adjust as needed. Inspect base plate anchor bolts to confirm that they are holding and tight. Inspect all lacing used to secure cover panels to the frame. Adjust any loose lacing and replace any that is damaged or chafed.

2.1.4. Frame Components. Any damage to the zinc coating on the steel framework should be sealed using a high quality sealant or a high zinc content coating (i.e. cold galvanizing compound) with at least 93% zinc in dry film. If a spray applicator is used, several thin coats are more effective than one heavy coat. It is essential to achieve proper coating thickness to ensure corrosion protection. If corrosion does develop on the surface, it should be removed with a wire brush and the area properly recoated. Seal the exposed anchor bolt threads with a high quality sealant or high zinc content paint. Check for loose cables—tighten as needed. Check all bolts and nuts— tighten as needed. Check door operation and grease (any lubricate manufacture) catch points along the track/roll area.

3.0 Repairs and Fabric Shelter Cleaning

3.1. Repairs

The contractor shall perform on-site routine repair services as required. Routine repairs are considered any replacement of parts and services not considered part of the normal OEM PM scheduled tasks. A service report detailing the needed repair shall be submitted to the AMARG POC for review / approval prior to any repairs being completed. The service report shall contain detailed itemization of all parts and labor required. The report must be legible, electronic (preferred) in a Microsoft Word, Excel or PDF format. Report shall include at a minimum the fabric shelter FEMS number, identification of the servicing technician and all parts and labor costs to complete the necessary repairs.

3.1.1. Repair Service Evaluation. All repair work must be initiated, authorized and approved by the AMARG POC and/or Contracting Officer and shall be ordered when the government determines repairs are required and cost effective. The contractor shall provide a quote using the

Repair Quote Template to include labor rate, hours and material costs (See Appendix 2).The government reserves the right to reject the offer to repair by the contractor in the event the repairs are deemed excessive based on the cost. The government reserves the right to solicit for a second quote for any repair exceeding $5,000.00 including parts and labor. In the event the second bid is determined to be less, the government reserves the right to hire the alternate contractor to perform the repair.

3.1.2. Repair Delays. If the contractor is unable to perform same-day repairs, due to circumstances beyond their control (e.g. awaiting parts), the contractor shall notify the AMARG POC of the delay and provide an estimated repair date. If the contractor is unable to perform repairs with-in five (5) days, due to circumstances beyond their control, the contractor shall notify the AMARG POCs of the delay and provide an estimated repair date at no additional charge to the government.

3.1.3. Repair Service Calls. Designated AMARG POC will place service calls to the contractor when immediate equipment repairs are necessary. The contractor shall respond to repair service calls within four (4) hours after receipt of the service call and work continuously until repairs are completed, at no additional cost to the Government. Repair service calls will be made between the hours of 7:30 a.m. to 1:30 p.m., Monday through Friday, except Federal Holidays.

3.1.4. Service Call Authorization. Upon contract award, the Contracting Officer will provide the contractor with a list of Government personnel authorized to place repair service calls, and the contractor shall only accept service calls from authorized personnel. If the contractor receives a service call from anyone other than authorized personnel, the contractor shall advise the caller to contact authorized personnel. The Government will not be responsible for calls placed by individuals other than those authorized by the Contracting Officer.

3.1.5. Repair Service Report. PM/Repair/Service Acceptance Report (SAR). The contract shall prepare a SAR after completion of any repairs/service, the contractor shall provide the AMARG POCs a legible SAR report prior to leaving AMARG. If services are deemed acceptable the AMARG POC will sign the SAR and return a copy to the contractor. SAR shall include the following information but not limited to:

• Type of service (e.g. PM, Cleaning, Service call, repairs).

• A description of all services performed during visit.

• Working status of repaired fabric shelter.

• List of parts replaced, including part number and cost.

• Signature and date of contractor personnel performing services.

3.2. Cover Fabric Tensioning Device Repair. The contractor shall perform on-site tensioning device repairs as required. Tension Ratchets: Any broken or frayed/torn ratchet straps will be replaced immediately. Tension straps: Any broken or frayed/torn will be replaced immediately.

3.3. PVC/Fabric Repairs. The contractor shall perform on-site fabric repairs as required.

3.3.1. Fabric Damage: When a problem is identified in the fabric membrane, the contractor will contact the AMARG POC immediately and a brief, written description, with photographs of the problem, will be provided. These photos will assist interpretation of the problem so a practical solution may be achieved. Any problems should be immediately brought to AMARG POC attention because a small tear, under tension or wind loading, may ultimately spread further.

AMARG POC will issue a brief, written remedial statement addressing the repair.

3.3.2. General Expectations of a Fabric Repair:

• Obtain appropriate fabric patch material that is three times the size of the damaged area.

For a 2” circular hole use a patch at least 6” in diameter. For a slice / tear that is 12” long the patch should be 6” wide by 18” long. For any hole or tear over 4” diameter, place fabric patches on both inside and outside surfaces of the damaged fabric.

• Gently clean surface of the damaged fabric with solvent (acetone, MEK or toluene) to remove oil and dirt from surface of the fabrics to be bonded. Wipe quickly and gently. Do not allow solvent to remain on PVC coated fabric for longer than necessary – it can damage the coating.

• Apply appropriate vinyl cement to both surfaces to be bonded. Shelter Structures manufacture recommends HH-66 Vinyl Cement (RH Products Company, Inc.). Follow application directions on the vinyl cement label. For best results two coats of cement are recommended.

• Apply a coat of vinyl cement to both surfaces to be joined and allow to dry before applying second coat.

• Assemble surface-to-surface and remove wrinkles/air bubbles with silicone roller while final coat is tacky. If necessary, apply solvent to cement coated areas with a cloth dampened with solvent to restore tackiness. Allow finished work to lie flat until fugitive solvent has evaporated.

• Heat Seal for small fabric shelters: Using a heat gun and a roller, cut a piece of fabric large enough to cover the tear, loosen the cover and get the edges as close as possible.

Use the heat gun to melt the patch to the main cover. You will need something rigid on the back side to roll against.

• Patch Tape for small fabric shelters: Cut of fabric large enough to cover the tear. Loosen the cover and get the edges as close as possible. Stick the tape over the tear and smooth.

WARNING!

VINYL CEMENT IS HIGHLY FLAMMABLE. KEEP AWAY FROM HEAT, SPARKS AND

OPEN FLAME. VAPORS HARMFUL IF BREATHED. FRESH AIR VENTILATION IS

NECESSARY, OTHERIWISE USE AIR SUPPLY HOOD OR CHEMICAL FACEMASK.

AVOID PROLONGED BREATHING OF VAPORS. AVOID PROLONGED CONTACT WITH

SKIN. WASH THOROUGHLY AFTER USING OR BEFORE SMOKING OR EATING. IN

CASE OF CONTACT, CALL PHYSICIAN. FOR EYE CONTACT, FLUSH REPEATEDLY.

HARMFUL OR FATAL IF SWALLOWED. DO NOT INDUCE VOMITING, CALL

PHYSICIAN. KEEP OUT OF THE REACH OF CHILDREN.

3.4. Replacement Parts and Materials. Contractor will supply Original Equipment Manufacturer (OEM) parts/material or Genuine parts/material. If a part/material is required, that is not on hand and needs to be ordered; the contractor must provide the AMARG POCs a cost estimate and get an approval from the AMARG POCs prior to ordering. All parts and material provided by the contractor must be in NEW condition meeting all OEM specifications.

Refurbished material shall not be utilized without AMARG POC or Contracting Officer approval. The Government will not be liable for any parts/material ordered without the AMARG POCs or Contracting Officer approval.

3.5 Cover Fabric (PVC) Cleaning Procedures:

Fabric Cleaning will be on an as needed basis (if the structure is subjected to unusually high rate of dirt and pollution exposure, cleaning may be required at the discretion of the AMARG POC).

The following procedure and methodology will always be followed. Any deviation from the cleaning procedure described within the PWS may void the fabric membrane warranty and fault will fall on contractor at no additional government expenses. Only the cleaning products listed in this section will be used. Should any circumstances require a more aggressive cleaning procedure, the contractor must contact AMARG POC prior to cleaning. The contractor must contact the AMARG POC prior to using any chemicals not listed in this section.

Note: Water will be available on AMARG, however, the contractor will be required to provide a vehicle for receipt and movement of water. WINSOL Deep Clean & Tent Clean Green have already been rated acceptable by John R. Maisch Water Manager DMAFB.

The 10" water spout is located on base approximately 1-2 miles from the site.

3.5.1. Approved Cleaning Products: APCO “Tent Clean Green” and Winsol Deep Clean.

Safety Data Sheets are available from manufacture.

3.5.2. Fabric Membrane Cleaning Procedure: Winsol Deep Clean and APCO “Tent Clean Green” are approved by manufacture and approved to be used in the desert area per 355 environmental. Usage instructions listed on the containers will always be followed. Winsol Deep Clean is available from Winsol Labs, Inc., 800-782-5501. “Tent Clean Green” is available from Awning Cleaning Industries, 800-542-3009.

3.5.2.1. (A) Mix WINSOL Deep Clean at a 1:16 ratio (8 oz. cleaner per gallon of water) for cleaning. For more aggressive cleaning ratio may be increased to 1:4 (32 oz. cleaner per gallon of water). (B) Mix “Tent Clean Green” at a ratio of 1:1 (1:2 for light soil). Follow all instructions on the product label. To improve performance, warm water may be used in the cleaning process.

As a safety precaution, it is recommended that the water temperature not exceed 85 degrees Fahrenheit (29⁰C). Water temperature may be increased to 110 degrees Fahrenheit (43⁰C) for cleaning heavy build-up. Extreme handling and spraying precaution must be taken to avoid scalding personnel.

AMARG POC)

1. Spray the cleaning solution directly onto the fabric using a garden sprayer or low pressure hose.

2. Do not use a pressure washer to clean the fabric membrane. It can abrade the protective PVC layer or even cut through the fabric scrim.

3. Clean the covers from top to bottom to avoid streaking.

4. A soft brush or sponge mop with an extension handle may be used to clean the fabric.

Ensure that no hardware on the applicator is exposed which could damage the fabric membrane.

5. Scrub the fabric using the soft brush in a circular motion.

6. If the foam (soapsuds) is dirty when scrubbing is completed, rinse and repeat until foam is clean-- Work in small areas and do not allow the cleaner to dry on the fabric.

7. Thoroughly rinse with water to remove dirt and detergent. It is important that all soap residue is removed so that a film does not develop. If not rinsed properly, this film may later attract additional dirt and pollution and the contract may be asked to repeat the cleaning at no additional cost to the government. Rinsing should be done before the detergent can dry and redeposit the soil on the fabric membrane.

3.5.2.2. Common chemicals and tools that must not be used in the cleaning process. Under no circumstances should the following tools and chemicals be used when cleaning the fabric membrane:

• Tools:

o Stiff Bristle Scrubbing brushes o Abrasives (sandpaper, grinders, wire brushes) o Scrapers (paint scrapers, putty knives, screwdrivers) o High pressure water / steam o Any items which may penetrate the fabric membrane

• Chemicals:

o Acetone o Gasoline o Benzene o Kerosene o Perchlorethylene o Ammonia o Nitric acid o Sulfuric acid o Acetic acid o Chlorhydric acid o Caustic soda o Bleach o Toulene

3.6. Warranty. The contractor shall warranty all preventative maintenance and repair services completed are free from defects in labor and materials for one (1) year, beginning on the date of acceptance by the government or invoice date. During the warranty period, any work to correct deficiencies in materials or workmanship shall be performed by the contractor at no additional cost to the government, as directed by the Contracting Officer. All contractor supplied parts shall carry the standard OEM commercial warranty.

3.7. Non-Personal Services. The government shall neither supervise contractor employees, nor control the method by which the contractor performs the required tasks. Under no circumstances shall the government assign tasks to, or prepare work schedules for individual contractor employees. It shall be the responsibility of the contractor to manage its employees and to guard against any actions that are of the nature of personal services, or give the perception of personal services. If the contractor believes that any actions constitute, or are perceived to constitute personal services, it shall be the contractor’s responsibility to notify the Contracting Officer immediately.
