About this file
This solicitation is for a design-build procurement to replace chillers and controls systems at the National Maritime Intelligence Center in Suitland, Maryland. The scope of work involves two major components - comprehensive replacement of the central utility plant equipment excluding condenser water, and replacement of the HVAC control system for all major equipment, distribution, and terminals. The design-build RFP includes performance criteria and a 15% design equivalent for the chiller and controls replacements. The Department of the Navy Naval Facilities Engineering Command is the issuing agency. Responses are due based on the posted solicitation schedule.

GPS EPO-FLEX MER II /18
EPO-FLEX® MER II
(Mechanical Equipment Room)
THE SHERWIN - WILLIAMS COMPANY
Advantages
• Bridges hairline cracks, thereby aiding in suppression of cracks reflecting through the system due to substrate movement
• Color options
• Durable, Slip resistant
• Waterproof
• Chemical and stain resistant
• Fiberglass scrim optional for maximum tensile strength
• VOC compliant, Low odor
Uses
• Mechanical Equipment Room
• Mezzanines
• Clean Rooms
• Lockers Rooms and Showers
• Computer Rooms
EPO-FLEX MER II (MECHANICAL EQUIPMENT ROOM) SYSTEM combines EPO-FLEX crack bridging and waterproofing capabilities with a chemically resistant topcoat and an optional wearcourse of EPO-FLEX broadcast to excess with hard aggregate would provide increased wear, impact, and abrasion resistance. EPO-FLEX achieves flexibility without the use of plasticizers or other additives which can separate or migrate as the system ages. This means that the product remains flexible and continues to function for many years. Fiberglass scrim may be incorporated into the system to add tensile strength.

Installation
General Polymers materials shall only be installed by ap-proved contractors. The following information is to be used as a guideline for the installation of the EPO-FLEX MER II (MECHANICAL EQUIPMENT ROOM) SYSTEM. Contact theTechnical Service Department for assistance prior to application.
Surface Preparation - General
General Polymers systems can be applied to a variety of substrates, if the substrate is properly prepared. Prepara-tion of surfaces other than concrete will depend on the type of substrate, such as wood, concrete block, quarry tile, etc. Should there be any questions regarding a spe-cific substrate or condition, please contact the Technical Service Department prior to starting the project. Refer to Surface Preparation (Form G-1).
Application Information
Material Mix Ratio Theoretical Coverage Packaging Per Coat Concrete
Primer 3579 2:1 250 sq. ft. / gal 3 or 15 gals
Membrane 3555 1:1 80 sq. ft. / gal 2 or 10 gals
Wearcourse 3555 1:1 130 sq. ft. / gal 2 or 10 gals Dry Silica Sand (30mesh) or Other Hard Aggregate .25 lbs. / sq. ft. 100 lbs
Seal Coat 3744 2:1 100-150 sq. ft. / gal 3 or 15 gals
Surface Preparation - Concrete
Concrete surfaces shall be abrasive blasted to remove all surface contaminants and laitance. The prepared con-crete shall have a surface profile equal to CSP 3-5. Refer to Form-G-1.
After initial preparation has occurred, inspect the concrete for bug holes, voids, fins and other imperfections. Protru-sions shall be ground smooth while voids shall be filled with a system compatible filler. For recommendations, consult the Technical Service Department.
Temperature
Throughout the application process, substrate tempera-ture should be 60ºF - 90ºF. Substrate temperature must be at least 5ºF above the dew point. Applications on concrete substrate should occur while temperature is fall-ing to lessen offgassing. The material should not be applied in direct sunlight, if possible.
Primer Mixing and Application
1. Premix 3579A (resin) using a low speed drill and Jiffy blade. Mix for one minute and until uniform, exercising caution not to introduce air into the material.
2. Add 2 parts 3579A (resin) to 1 part 3579B (hard-ener) by volume. Mix with low speed drill and Jiffy blade for three minutes and until uniform. To insure proper system cure and performance, strictly follow mix ratio recommendations.
3. 3579 may be applied via spray, roller or brush. Ap-ply 5-8 mils, evenly, with no puddles. Coverage will vary depending upon porosity of the substrate and surface texture.
4. Wait until primer is tacky (usually 1 hour minimum), before applying the membrane. If primer is not going to be topped within open time, broadcast silica sand into resin lightly but uniformly and allow to cure overnight.
Membrane Mixing and Application - If priming is done to reduce outgassing, allow to cure overnight before topping
1. Premix 3555A (resin) using a low speed drill and Jiffy blade. Mix for one minute and until uniform, exercising caution not to whip air into the material.
2. Add 1 part 3555A (resin) to 1 part 3555B (hardener) by volume. Mix with low speed drill and Jiffy blade for three minutes and until uniform. .
3. Immediately pour the mixed material onto the sub-strate and pull out using a 1/4" or 1/8" v-notched squee-gee to yield 20 mils WFT and cross roll with a 3/8" nap roller. Readings must be taken continuously during application with a wet mil gauge to verify material is being applied at the proper thickness. Allow to cure overnight at 73ºF surface temperature. Material cures slower at lower temperatures.
4. After the membrane is cured, check for surface blush.
Remove any blush with detergent wash prior to apply-ing wearcourse.
Wearcourse Mixing and Application
1. Premix 3555A (resin) using a low speed drill and Jiffy blade. Mix for one minute and until uniform, exercising caution not to whip air into the material.
2. Add 1 part 3555A (resin) to 1 part 3555B (hardener) by volume. Mix with low speed drill and Jiffy blade for three minutes and until uniform.
3. Immediately pour the mixed material onto the sub-strate and pull out using a 1/4" or 1/8" v-notched squee-gee to yield 12 mils WFT and cross roll with a 3/8" nap roller. Readings must be taken continuously during ap-plication with a wet mil gauge to verify material is being applied at the proper thickness. Material cures slower at lower temperatures.
4. Broadcast Dry Silica Sand (30 mesh) or other Hard Aggregate to excess into wet material so no wet mate-rial is visible. Aggregate should be broadcast within one (1) hour of liquid application to ensure they are properly seated.
5. Allow to cure (Cure times vary depending on environ-mental conditions), sweep off excess aggregate with a clean, stiff bristled broom. Clean aggregate can be saved for future use. All imperfections such as high spots should be smoothed before the application of the seal coat.
NOTE: The floors finished appearance depends on the manner in which the aggregate has been applied. In grass seed like fashion, allow the aggregate to fall after being thrown upward and out. DO NOT THROW
DOWNWARD AT A SHARP ANGLE USING FORCE.
Seal Coat Mixing and Application
1. Premix 3744A (resin) using a low speed drill and Jiffy blade. Mix for one minute and until uniform, exercising caution not to introduce air into the material.
2. Add 2 parts 3744A (resin) to 1 part 3744B (hardener) by volume. Mix with low speed drill and Jiffy blade for three minutes and until uniform. To insure proper system cure and performance, strictly follow mix ratio recommenda-tions.
3. Apply 3744 using a flat trowel or squeegee and backroll with a 1/4" nap roller at a spread rate of 100-150 sq. ft. per gallon, evenly, with no puddles making sure of uniform coverage. Take care not to puddle materials and insure even coverage.
4. Allow to cure 24 hours minimum before opening to traffic.
Epoxy materials will appear to be cured and “dry to touch” prior to full chemical cross linking. Allow 3744 to cure for 2-3 days prior to exposure to water or other chemi-cals for best performance.
Cleanup
Clean up mixing and application equipment immediately after use. Use toluene or xylene. Observe all fire and health precautions when handling or storing solvents.
Safety
Refer to the MSDS sheet before use. All applicable fed-eral, state, local and particular plant safety guidelines must be followed during the handling and installation and cure of these materials.
Safe and proper disposal of excess materials shall be done in accordance with applicable federal, state, and lo-cal codes.
Material Storage
Store materials in a temperature controlled environment (50ºF - 90ºF) and out of direct sunlight.
Keep resins, hardeners, and solvents separated from each other and away from sources of ignition. One year shelf life is expected for products stored between 50ºF - 90ºF.
Maintenance
Occasional inspection of the installed material and spot repair can prolong system life. For specific information, contact the Technical Service Department.
