The contractor shall have a minimum of 3 years experience in similar work as specified in this Statement of Work (SOW). The contractor shall consistently provide quality services to include painting of interior and exterior surfaces, pavement markings, floor refinishing, and signage program in accordance with contract documents and standards of the industry. The contractor shall not substitute paint systems (enamel, latex, etc.) that do not match the existing paint system without the COR’s approval. Work will normally be done with the facility occupied. This contract does not give the contractor exclusive right to perform work that falls within the scope of the contracts on Sheppard Air Force Base (SAFB) or satellite facilities; government personnel or other contractors may be solicited to perform the same type of work that may be included in major projects.

1.1 Location:

Sheppard AFB is located in Wichita County in the northern part of Wichita Falls, Texas. Contractor and contract employees shall enter Sheppard AFB through the Missile Road gate, located at the intersection of Burkburnett Road and Missile Road. Due to Air Force Protection Conditions (FPCON) measures, vehicles may be inspected and delays entering and exiting through the gates is not uncommon. Any cost of delays will be at no cost to the government. The main gate may be used only in the event that the Missile Road gate is closed. The contractor will be required to maintain facilities outside Sheppard AFB boundaries.

These include Lake Texoma Recreational Annex, which is located in Grayson County, Texas (approximately a 2-hour drive from Sheppard AFB), and Frederick Auxiliary Airfield, located in Tillman County, Oklahoma (approximately a 1-hour drive from Sheppard AFB). The contractor will be paid for vehicular mileage on a per vehicle basis under CLIN X0013, Travel Mileage.

2 SCHEDULES:

2.1 Normal Job Orders:

Work orders shall be submitted to the contractor by the COR using the Job Order Form (Appendix 1).

Work shall start on a normal job order within 7 business days of issuance, and shall be completed no later than 30 calendar days from issuance unless otherwise agreed upon in writing with the COR and annotated on the Job Order form. All governmental delays and/or weather delays must be provided in writing from the contractor if to be considered toward recalculating completion date. Government delays include but not limited to base closure, denied access to working area, or request to re-prioritize a different job causing contractor to pull off issued job currently working. The contractor shall have available, during normal duty hours, a point of contact for receiving all requests for work. It is the contractor’s responsible to check on a daily basis for job orders from the COR (currently located in building 1402/Civil Engineering). Estimated workload and material quantities shall be agreed upon between the contractor and the COR before the work starts. If the contractor subsequently becomes aware that the actual workload and material requirements are different from those previously agreed upon, the contractor must notify the COR before proceeding further with the project.

2.1.1 Filing System:

A copy of the all completed job order forms shall be submitted to the COR no later than by 1500 hours on Fridays or as completed. In the event of a holiday, the completed forms will be submitted the duty day prior to the holiday. A copy of the contractor's invoice shall be submitted to the COR by the Tenth business day the following month. Contractor’s portion of the job order forms will be filled out completely including the date quality control (QC) was accomplished and a signature of the Quality Control Contract Manager (QCCM). (See Appendix 1 – Job Order Form)

2.1.2 Rescheduling:

All work shall normally be started and completed on a first in, first out basis, except when directed by the COR. However, should the needs of the government change, the COR reserves the right to reprioritize projects at any time after they have been issued to the contractor at no additional cost to the government.

2.1.3 Priority Job Order:

A Priority Job Order is a job order which must be started within 24 hours of issuance to the contractor unless a later start date has been coordinated in advance. For example, the Priority Job Order is issued Aug 1 but the government does not want the contractor to start within 24 hours but rather start on Aug 15, the contractor must work it immediately on Aug 15 since it was issued as a priority with advance start date. Once a priority job is started, it shall be worked continuously during normal duty hours by a work force that is reasonable for the scope of work outlined in the job order. The contractor has 7 business days from issuance to complete a Priority Job Order unless a different date is agreed upon by the contractor and the COR and based on the reasonable timeframe a larger job would require to complete. The contractor shall have the manning and resources sufficient to be able to successfully accomplish 15 percent of the total uncompleted job orders issued under the constraints of a Priority Job Order. For example, if a total of 105 open job orders have been issued to the contractor, the COR has the authority to designate up to 15 of those open job orders as a Priority Job Order. This may be done at any time and is not limited to the initial issuance of the job order. The issuance of a Priority Job Order shall not prevent the contractor from finishing Normal Job Orders on schedule.

3 PAINTING:

3.1 Interior:

Interior paint price shall include the price for surface preparation (see Section 3.8), finish painting of all surfaces assigned, moving furniture before the job and replacing furniture after the job and all cleanup work.

Generally, interior painting shall conform to Federal Standard 595b colors X7780, X7056, X6622, X6306, X6251, and X0099. Semi-gloss or flat paints (designated by "2" or "3", respectively, in place of the "X") may be used. The COR may request new colors that vary from existing color schemes. These new colors shall be applied at no additional cost to the government based on color alone. When existing color schemes vary from those colors listed above, the contractor may have to provide a primer application sufficient to ensure hiding is achieved as directed by the COR. The contractor will invoice for this primer under CLIN X003AB, Interior Primer. Contractor shall display professional (not hand written) wet paint signs in sufficient numbers and shall be posted at all entrances and exits around the job site, and other locations throughout the job. Once the paint is dry, the contractor must remove all signage.

3.1.1 Controlled Entry Facilities:

Painting of facilities with controlled entry requires prior coordination between the building’s facility manager and possibly the installation information security Non Commissioned Officer (NCO) before painting can be started in these facilities. It is likely that Controlled Entry facilities will require a full time escort for the contractor at all times, this too will need to be closely coordinated. Occasionally, controlled area have mandatory rules that must be followed such as but not limited no cell phone usage while in the

SOW 4 of 33 controlled area; the contractor will comply with all rules and regulations for the controlled area. The contractor is encouraged to contact the COR if coordinating access to these areas is difficult to accomplish and the COR will provide assistance.

SOW 6 of 33

SOW 7 of 33

Protective Coating Maintenance reflecting barrier that improves comfort, reduces heating and cooling requirements and dampens ambient noise. The contractor shall provide and mix the paint additive into the appropriate paint color and type when requested on the job order. The contractor shall adhere to manufacturer’s directions for use, application, and mixing. The manufacture may recommend multiple coats be applied, however the government will indicate on job order if one coat or two coats are requested; if two coats are request, both coats shall contain the paint additive. The additive comes in one gallon pouches or five gallon pouches; one gallon pouch is to be used per one gallon of paint and five gallon pouch is to be used for five gallons of paint. The additive does cause slight thickening of the paint, therefore the contractor must use a larger container to mix therefore the contractor will not be able to add one gallon pouch directly to one gallon paint container, the mixing container must be slightly larger. The pouches must be added gradually to the paint while stirring to ensure even distribution of the additive. Contractor shall stir paint prior to commencing application if the paint has been sitting for more than 2 hours since last used as the additive may not be evenly distributed and sink toward bottom. The paint additive shall be nontoxic and Energy Star® product such as Insuladd manufactured by Tech Traders or equal.

All paint additives must be submitted to government for approval prior to use.

3.7.1 Applying Paint Additive:

Paint with additive added can be applied to interior or exterior surfaces with brush, roller or with a sprayer. Surface preparation is the same as referenced in Section 3.8, Preparation of Surfaces. If spraying painting with paint additive it is recommended a paint spray gun tip in the size range of .617 to .621 works well for most applications however thicker coating additives may required larger tip. When using the spraying application, if needed, the contractor can add ½ to 1 cup of water per gallon of paint to help the paint flow. It is important to remove the small cartridge filter from the spray gun prior to painting with additive since the filter will try and strain all of the additive granules from the paint.

3.7.2 Unused Paint with Additive:

Any unused paint can be stored back in its original container. Upon use it must be stirred to evenly distribute the granules throughout the paint. Contractor must clearly mark ALL paint cans which have the paint additive to distinguish it from other paints without the paint additive.

3.7.3 Payment of Additive:

The contractor will be issued a job order that will be clearly marked “PAINT ADDITIVE” to be added to one coat or two coats, if two coats are requested both coats shall have the paint additive unless otherwise annotated on job order. Contractor will be paid through the appropriate Contract Line Item (CLIN) such as CLIN001AA for exterior, surfaces under 25’; CLIN001AB for exterior, surfaces over 25’;

CLIN003AA for interior surfaces) at the bid price per square foot and the government will add CLIN 014, Paint Additive to the Job Order at the bid price per square foot. CLIN014 will only include the additional cost for the paint additive as a supplement to the other CLINS and will not include surface preparation or paint as that is already factored into the appropriate paint CLIN (001AA, 001AB, and 003AA). CLIN 014 will always be issued with an Exterior or Interior CLIN, but not all interior or exterior jobs will include CLIN014 only those facilities the government determines to be a candidate for the paint additive.

For example:

Square Footage X contractor’s bid price $ for CLIN001AA, Exterior Surfaces under 25’

PLUS

Square Footage X contractor’s bid price $ for CLIN014, Paint Additive ONLY

3.7.4 Payment of Multi Ceramic Roofing Paint:

The contractor will be issued a job order that will be clearly marked “Multi Ceramic” to be used for the roofs. Contractor will be paid through the appropriate Contract Line Item X015;

6.1 Pavement Marking Removal:

The contractor is required to remove layers of paint, tape, or thermoplastic pavement stripping/markings.

The removal is to be completed without damage to the pavement surface, joints, and joint and crack seals, or any other government property. Disposal of waste shall be in compliance with local, state, and federal regulations.

6.2 Surface Preparation

Surfaces to be marked shall be thoroughly cleaned before application of the pavement marking material. Dust, dirt, peeling or poorly bonded paint, and other granular surface deposits shall be removed by sweeping, blowing with compressed air, rinsing with pressurized water or a combination of these methods as required. The price for this type of preparation shall be included in the price for pavement marking material application (paint or tape).

6.2.1 Cleaning:

Rubber deposits, surface laitance, existing paint markings, and other coatings adhering to the pavement shall be completely removed with scrapers, wire brushes, approved chemicals, or mechanical abrasion as directed by the COR and industry standards. Whenever grinding, scraping, or other operations are performed the work shall be conducted in such a manner that the finished pavement surface is not damaged or left in a pattern that is misleading or confusing.

6.2.1.1 Old Pavements:

Areas of old pavement affected with oil or grease shall be scrubbed with several applications of approved detergent or degreaser to clean pavement areas. Areas that may require this type of cleaning include:

intersections and parking lots, maintenance aprons, engine run-up areas, blast pads, and the threshold and rotation area of the runway. After cleaning, the area shall be thoroughly rinsed. After cleaning, oil-soaked areas shall be sealed to prevent bleeding through the new paint. Pavement surfaces shall be allowed to dry, when water is used for cleaning, prior to stripping or marking. When these operations are completed the pavement surface shall be blown off with compressed air to remove residue and debris resulting from the cleaning work. Any areas exposed to rain or traffic after cleaning shall be cleaned again before marking.

6.3 Weather Conditions:

Pavement marking will be suspended when weather conditions interfere with uniform application of pavement marking materials. All markings shall be uniform in length and width, with a clean cut-off at the ends and edges. Pavement marking shall be suspended during rain, snow, fog, ice, slush, mist, or when the pavement surface is wet. Apply paint to clean and dry surfaces.

6.4 Equipment:

All machines, tools, and equipment used in performance of the work shall be of suitable type and shall be maintained in satisfactory operating condition. Hand operated push-type machines of a type commonly used for application of paint to pavement surface shall be acceptable for marking small streets and parking areas. Markings shall be performed with an industry standard purpose-built machine that uses an automatic bead dispenser attached to the pavement marking equipment, and can provide continuous mixing and agitation of the pavement marking material. Applicator machines shall be equipped with the necessary paint tanks and spraying nozzles, and shall be capable of applying paint uniformly at coverage specified. Hand operated spray guns shall be used in areas where push-type machines cannot be used.

SOW 14 of 33

6.4.1 Paint Applicator:

The equipment for applying the paint binder may be self-propelled, mobile drawn or propelled by hand and shall be a pneumatic spraying machine with an arrangement of atomizing nozzles capable of applying in a single pass a line 6 inches in width. However, equipment for painting street centerline and edge markers and any line type markings on airfield pavement shall be self-propelled. The machine shall be capable of applying the paint at the rates specified by the manufacturer of the paint to be applied.

Paint shall be applied at an even and uniform thickness, with clear-cut edges. The spray mechanism shall be operated by means of quick opening and closing valves conveniently located and shall include necessary pressure regulators and gauges in full view and reach of the operator at all times. Paint strainers shall be installed in the paint supply lines to ensure freedom from residue and foreign matter that may cause malfunction of the spray guns.

6.4.2 Reflective Media Dispenser:

The dispenser for drop-on of the reflective media shall be attached to the paint dispenser and operate automatically and simultaneously with the paint applicator through the same control mechanism.

The dispenser shall be designed to provide uniform flow of reflective media at the established rate of coverage as indicated above regardless of the speed of the paint applicator to which it is attached.

6.4.3 Pre-formed Marking Application Equipment:

Mechanical application equipment shall be used for the placement of preformed pavement markings. Mechanical application equipment shall be defined as a mobile pavement-markings machine specifically designed for use in applying pre-coated, pressure-sensitive pavement markings of varying widths, up to 12 inches. The inlay method, where the preformed marking is rolled into the freshly laid HMAC (hot mix asphalt cement) paving mixture using a steel-wheeled roller is the specified application method. Should circumstances preclude the use of the inlay method, or the markings be scheduled for installation on PCC (Portland concrete cement) pavements, the contractor shall follow the manufacturer's installation instructions. As a minimum, the applicator used shall be equipped with rollers, or another suitable compaction device, to provide initial adhesion of the preformed, pressure-sensitive markings to the pavement surface. Additional hand-operated rollers shall be used as required to properly seal the preformed markings. Adhesives or glues shall also be used as applicable and as recommended by the manufacturer to achieve the desired results.

6.5 Traffic Controls:

Suitable warning signs shall be placed around the work site for alerting approaching traffic from both directions. Signs shall be professional looking. Place small markers along newly painted lines to control traffic and prevent damage to newly painted surfaces. Mark painting equipment with large warning signs indicating slow-moving painting equipment in operation. It is the contractor’s responsibility to coordinate with security forces prior to placing traffic cones or blocking traffic. The contractor shall provide and place all traffic cones or barriers when stripping or marking pavements. At no time shall the cones or barriers at any work site block more than half of the street block. The cones or barriers shall be placed to avoid traffic congestion and safety hazards. Upon completion of work and when the paint is completely dry, the contractor shall remove all cones, barriers, and markers.

6.6 Application:

6.6.1 Paint:

Protection for non-painted areas is the responsibility of the contractor. Adjacent areas shall be protected by the use of drop cloths or other approved measures. All over-spray is the responsibility of the contractor and shall be removed.

Paint shall be applied with approved equipment at rate of coverage recommended by the paint manufacturer. The contractor shall provide guidelines and templates as necessary to control paint application. Special precautions shall be taken when marking numbers, letters, and symbols. Edges of markings shall be sharply outlined. The maximum drying time requirements of the paint specifications shall be strictly enforced to prevent displacement or discoloration by tires of traffic. If there is a delay in drying of the markings, painting operations shall be discontinued until cause of the slow drying is determined and corrected. Paints used with reflecting media shall be the slow drying type to promote adherence of the reflective media.

6.6.1.1 Reflective Media:

Application of reflective media shall immediately follow application of pigmented binder. Drop-on application of glass spheres shall be accomplished to insure that reflective media is evenly distributed at the specified rate of coverage. Should there be malfunction of either paint applicator or reflective media dispenser, operations shall be discontinued immediately until deficiency is corrected. Reflective media shall be applied to all pavements stripping to include parking lots, crosswalks, stop bars, center and side dividers.

6.7 Preformed Markings

Application shall be according to current industry standards and in accordance with manufacturer’s instructions. See paragraph on Pre-formed Marking Application Equipment above.
