Statement of Work (SOW):

1. The Morris facility is a soils research facility that is currently conducting research to identify herbicides that do not pose a risk to various oilseed crops. As a result of this research, a new fume hood and base cabinet, and other associated work is needed. A general description of the works is:

A recent project at Morris provided for a new fume hood and cabinets in Room 105 (Bldg. 8). The work in Room 102 will be similar as an existing exhaust duct will be utilized, utilities provided to the fume hood will be the similar, base cabinets will be similar as well. A notable difference is that the fume hood in Room 102 shall be a six feet model rather than the four feet model provided in Room 105. All work required for a complete and fully functioning system shall be provided by the Contractor, including, but not limited to all mechanical, electrical, plumbing, test and balance, commissioning, and some architectural work. A more detailed description of the work is provided below.

The work will also consist of applying a liquid flashing product to the three roof-top metal flashings and various joints at the existing fume hood exhaust stacks.

2. This SOW consists of a written description of the work, pictures showing typical project conditions (that may or may not include additional written descriptions), existing drawings, fume hood specifications and data, referenced standards, and the like. FAR Solicitation and Contract clauses are identified in the complete Solicitation package.

i. Air

ii. Vacuum

iii. Deionized water

iv. Hot water (connected to mixing valve)

v. Cold water (connected to mixing valve)

In the left rear of the hood there shall be a cup sink with a spigot that will furnish hot/cold water.

On the left side (inside the hood) there shall be angled valves with serrated ends for air, vacuum, and deionized water.

b. All work must comply with the most recent Minnesota State Building Codes, as well as specific Morris, MN Building codes. In the event that there is a conflict, the more stringent requirement shall apply.

2020 Minnesota State Building Codes | Minnesota Department of Labor and Industry (mn.gov)

c. There is an existing stainless steel vent stack that is to be reused, similar to the Room 105 fume hood installation. The existing vent stack appears to be mostly centered on the new six feet wide fume hood; however, the Contractor is responsible for any transition pieces needed to align the new fume hood with the existing vent stack. Verify in field. Transition pieces, if needed, may be factory components, or shop fabricated. In either case, the pieces shall be of the same material and fully compatible with the new fume hood and existing vent stack.

Chemical spot tests for non-volatile chemicals shall be made by applying 5 drops of each reagent to the surface to be tested and covering with a 1-1/4" dia. watch glass, convex side down to confine the reagent. Spot tests of volatile chemicals shall be tested by placing a cotton ball saturated with reagent on the surface to be tested and covering with an inverted 2-ounce wide mouth bottle to retard evaporation. All spot tests shall be conducted in such a manner that the test surface is kept wet throughout the entire test period, and at a temperature of 77° ±3° F. For both methods, leave the reagents on the panel for a period of one hour. At the end of the test period, the reagents shall be flushed from the surface with water, and the surface scrubbed with a soft bristle brush under running water, rinsed and dried. Volatile solvent test areas shall be cleaned with a cotton swab soaked in the solvent used on the test area. Immediately prior to evaluation, 16 to 24 hours after the reagents are removed, the test surface shall be scrubbed with a damp paper towel and dried with paper towels.

1. Test Evaluation:

Evaluation shall be based on the following rating system.

Level 0 – No detectable change.

Level 1 – Slight change in color or gloss.

Level 2 – Slight surface etching or severe staining.

Level 3 – Pitting, cratering, swelling, or erosion of coating.

Obvious and significant deterioration.

After testing, panel shall show no more than three (3) Level 3 conditions.

3. Performance Test Results (Heat Resistance):

Hot water (190° F - 205° F) shall be allowed to trickle (with a steady stream at a rate not less than 6 ounces per minute) on the finished surface, which shall be set at an angle of 45° from horizontal, for a period of five minutes. After cooling and wiping dry, the finish shall show no visible effect from the hot water treatment.

4. Performance Test Results (Impact Resistance):

A one-pound ball (approximately 2" diameter) shall be dropped from a distance of 12 inches onto the finished surface of steel panel supported underneath by a solid surface. There shall be no evidence of cracks or checks in the finish due to impact upon close examination.

5. Performance Test Results (Bending Test):

An 18-gauge steel strip, finished as specified, when bent 180° over a 1/2" diameter mandrel, shall show no peeling or flaking off of the finish.

11 53 13-VFH-10 11/20

6. Performance Test Results (Adhesion):

Ninety or more squares of the test sample shall remain coated after the scratch adhesion test. Two sets of eleven parallel lines 1/16" apart shall be cut with a razor blade to intersect at right angle thus forming a grid of 100 squares. The cuts shall be made just deep enough to go through the coating, but not into the substrate. They shall then be brushed lightly with a soft brush. Examine under 100 foot-candles of illumination. Note: This test is based on ASTM D2197-68, "Standard Method of Test for Adhesion of Organic Coatings".

7. Performance Test Results (Hardness):

The test sample shall have a hardness of 4-H using the pencil hardness test. Pencils, regardless of their brand are valued in this way: 8-H is the hardest, and next in order of diminishing hardness are 7-H, 6-H, 5-H, 4-H, 3-H, 2-H, F, HB, B (soft), 2-B, 3-B, 4-B, 5-B (which is the softest).

The pencils shall be sharpened on emery paper to a wide sharp edge. Pencils of increasing hardness shall be pushed across the paint film in a chisel-like manner until one is found that will cut or scratch the film. The pencil used before that one-that is, the hardest pencil that will not rupture the film is then used to express or designate the hardness.

B. Fume Hood Liner Performance:

1. Chemical Spot Tests - 24 Hours:

Chemical spot test shall be made by applying 10 drops (approximately 1/2 cc) of each reagent to the surface to be tested. Each reagent (except those marked **) shall be covered with a 1-1/2" diameter watch glass, convex side down to confine the reagent. Spot tests of volatile solvents marked ** shall be tested as follows: A 1" or larger ball of cotton shall be saturated with the solvent and placed on the surfaces to be tested. The cotton ball shall then be covered by an inverted 2-ounce, wide mouth bottle to retard evaporation. All spot tests shall be conducted in such a manner that the test surface is kept wet throughout the entire 24-hour test period and at a temperature of 77 degrees F. + 3 degrees F. At the end of the test period, the reagents shall be flushed from the surfaces with water and the surface scrubbed with a soft bristle brush under running water, rinsed, and dried. Volatile solvent test areas shall be cleaned with a cotton swab soaked in the solvent used on the test area.

Spots where dyes have dried shall be cleaned with a cotton swab soaked in alcohol to remove the surface dye. The test panel shall then be evaluated immediately after drying.

2. Legend / Ratings:

1 - Glass Reinforced Polyester A = No effect or slight change in gloss 2 - Stainless Steel 304 B = Slight change in gloss or color 3 - Stainless Steel 316 C = Slight etching or severe staining 4 - Reinforced Phenolic Resin D = Swelling, pitting, or severe etching
