BB. Repairing Formed Surfaces: Surface defects include color and texture irregularities, cracks, spalls, air bubbles, honeycombs, rock pockets, fins and other projections on the surface, and stains and other discolorations that cannot be removed by cleaning.

CAST-IN-PLACE CONCRETE 033000-7

Immediately after form removal, cut out honeycombs, rock pockets, and voids more than 1/2 inch in any dimension in solid concrete, but not less than 1 inch in depth.

Make edges of cuts perpendicular to concrete surface. Clean, dampen with water, and brush-coat holes and voids with bonding agent. Fill and compact with patching mortar before bonding agent has dried. Fill form-tie voids with patching mortar or cone plugs secured in place with bonding agent.

Repair defects on surfaces exposed to view by blending white portland cement and standard portland cement so that, when dry, patching mortar will match surrounding color. Patch a test area at inconspicuous locations to verify mixture and color match before proceeding with patching. Compact mortar in place and strike off slightly higher than surrounding surface.

Repair defects on concealed formed surfaces that affect concrete's durability and structural performance as determined by CO.

CC. Repairing Unformed Surfaces: Test unformed surfaces, such as floors and slabs, for finish and verify surface tolerances specified for each surface. Correct low and high areas. Test surfaces sloped to drain for trueness of slope and smoothness; use a sloped template.

Repair finished surfaces containing defects. Surface defects include spalls, popouts, honeycombs, rock pockets, crazing and cracks in excess of 0.01-inch wide or that penetrate to reinforcement or completely through unreinforced sections regardless of width, and other objectionable conditions.

After concrete has cured at least 14-days, correct high areas by grinding.

Correct localized low areas during or immediately after completing surface finishing operations by cutting out low areas and replacing with patching mortar. Finish repaired areas to blend into adjacent concrete.

Correct low areas scheduled to remain exposed with a repair topping. Cut out low areas to ensure a minimum repair topping depth of 1/4-inch to match adjacent floor elevations. Prepare, mix, and apply repair topping and primer according to manufacturer's written instructions to produce a smooth, uniform, plane, and level surface.

Repair defective areas, except random cracks and single holes 1 inch or less in diameter, by cutting out and replacing with fresh concrete. Remove defective areas with clean, square cuts and expose steel reinforcement with at least a 3/4-inch clearance all around.

Dampen concrete surfaces in contact with patching concrete and apply bonding agent.

Mix patching concrete of same materials and mixture as original concrete except without coarse aggregate. Place, compact, and finish to blend with adjacent finished concrete. Cure in same manner as adjacent concrete.

Repair random cracks and single holes 1 inch or less in diameter with patching mortar.

Groove top of cracks and cut out holes to sound concrete and clean off dust, dirt, and loose particles. Dampen cleaned concrete surfaces and apply bonding agent. Place patching mortar before bonding agent has dried. Compact patching mortar and finish to match adjacent concrete. Keep patched area continuously moist for at least 72-hours.

D. Install pump stand by connecting the suction/lift pipe assembly and bolting the pump stand to the casing. Ensure that suction pipe and casing flange connections are watertight. After bolting the pump stand to the casing, run a bead of high stretch urethane acrylic caulk, ASTM-C920 Type S, Grade NS, Class 25, between the base of the pump stand and the well casing.

E. Drill a 1/16-inch weep-hole in the lift pipe so that it is located about 8 feet below the ground surface.

CLEANING

F. All chemicals used to disinfect the well shall meet ANSI/NSF 60.

G. Prior to assembly and installation of the suction pipe assembly, clean the cylinder, pipe and rod of all foreign substance and then disinfect the components with a 200-ppm chlorine solution.

H. Upon completion of the hand pump installation, disinfect well according to AWWA- A100 and AWWA-C654.

Disinfect well with a solution equal to 100-ppm free chlorine, after mixing with the water in the well.

Introduction of Chlorine Solution to the Well: The method of introducing the chlorine into the well shall be one of the following as recommended by AWWA-C654 and approved by the CO:

HAND PUMP REPAIR 221123-5

1. Calcium Hypochlorite: Dribble tablets of approximately 5-gram size down the casing vent and wait at least 30 minutes for the tablets to fall through the water and dissolve.

2. Sodium Hypochlorite: Suspend a tube through the well casing vent so that it reaches the bottom of the well. Withdraw the tube as the sodium hypochlorite solution is pumped through the tube.

The water in the well must be agitated to mix the solution thoroughly. Surfaces of all components above the water level must be flushed or washed down with the sterilizing solution.

The chlorine solution shall remain undisturbed in the well for a period of a least 12 hours, but not more than 24 hours.

Removing Disinfection Solution from the Well: After disinfection, the well shall be pumped for a minimum of 15 minutes beyond the time that a zero chlorine residual is first detected by the Contractor.

The chlorinated water shall be “quenched” of free chlorine by the use of sodium thiosulfate, food grade vitamin C, or other approved method prior to discharge, to bring the free chlorine level in the discharge stream to less than 0.5-ppm.

Have onsite at all times during the disinfection, a Colorimeter, capable of testing to 200-ppm of dissolved chlorine, and 0-10-ppm free chlorine. Provide CO opportunity to observe testing of the chlorine levels.
