01 10 00-2

1.3 MAINTAINING WATER SERVICE DURING CONSTRUCTION

A. The cistern is divided into three sections. Section 1 contains potable water. Sections 2 and 3 contain non-potable water. Only one section shall be taken out of service at one time.

Interruptions to water service shall be kept to a minimum. Interruptions to either potable water or non-potable water shall be less than 2-hours.

B. The sequent of working on the tanks shall be as follows:

1. The Contractor shall first dewater Section 3 by transferring as much water as can fit into Section 2 and wasting the rest.

2. When Section 3 is complete, the Contractor shall dewater Section 1 (which contains potable water) by transferring the water to Section 3. To do this, Section 3 must first be disinfected, and the piping modified so the RO plant will discharge to Section 3 and the potable water pumps can draw from Section 3.

3. When Section 1 is complete, it shall be disinfected, and potable water shall be transferred back from Section 3. The piping shall be restored to use the Section 1 as the potable water tank.

4. Finally, Section 2 can be dewatered by transferring its water to Section 3.

1.4 USE OF PREMISES

A. Limit use of premises to the project work area. Do not disturb portions of site beyond the work area. The work area is defined as 15 feet from any of the new facilities being installed.

B. All facilities on the island shall remain open during construction. Minimize the number and length of power outages.

C. The Contractor shall always conduct his operations to ensure the least inconvenience to the public.

D. Confine storage of materials to the approved storage area. The Contractor can use up to 3,000 square feet area adjacent to the tanks for storage.

1.5 RESOURCE PROTECTION

SECTION 09 97 00 – LIME WASH

PART 1 - GENERAL

1.1 SUMMARY OF WORK

A. The work of this section is to apply lime wash to the cistern exterior top and exposed exterior walls.

1.2 SUBMITTALS: As specified in Section 01 33 00.

A. Manufacturer's literature for the lime.

PART 2 - PRODUCTS

2.1 LIME

A. Use either lime putty per ASTM C1489 or hydrated lime per ASTM C206, Type S.

PART 3 - EXECUTION

3.1 MIXING LIME WASH

A. Lime wash may be made from either lime putty or hydrated lime. Add water to make a slurry with the consistency of whole milk. This consistency should be approximately 15 to 20% lime and 80 to 85% water. Lime wash should be mixed long enough to assure that all the lime is in suspension. Mix with a motorized long-stemmed paddle stirrer. Screen lime wash through a 1/8-inch screen before applying.

3.2 APPLICATION

A. Wash surface with water and scrub with a brush to remove dirt and loose material.

B. Dampen surface with water so it is wet but without standing water.

C. Apply lime wash with a large soft bristle brush. During application with the brush, use a scooping and swirling motion in the pail to keep the mix suspended. Work in patterns that assure full coverage and maintains a wet edge where applying. Apply the lime wash liberally and work it into the surface with strokes in many directions (up, down, and diagonal). Expect the lime wash to splatter off of the brush and be rather messy. Drop cloths and masking should be used for areas that will not be covered by lime wash.

3.3 COATS

A. Apply three coats of lime wash. Wait 24 hours between coats.
