SECTION 02 82 13 ASBESTOS ABATEMENT.

1.3.5 HANDLING OF LEAD

The gantry crane was painted with a lead based primer. All structural steel that is painted shall be considered to be contaminated with lead based paint and must be handled and disposed of in accordance with SECTION 01 57

19 ENVIRONMENT PROTECTION, and SECTION 02 83 13, LEAD IN CONSTRUCTION.

1.4 REGULATORY AND SAFETY REQUIREMENTS

Comply with federal, state, and local hauling and disposal regulations.

1.9 REMOVAL PLAN

The Removal Plan must include procedures and sequences for careful removal

SECTION 02 41 16.00 26 Page 4 and disposition of materials specified to be removed from site, a disconnection schedule of utility services, and a detailed description of methods and equipment to be used for each operation and of the sequence of operation. Provide procedures for safe conduct of the work in accordance with EM 385-1-1. Removal Plan must be approved prior to mobilization to site. Indicate areas that may be weakened as a result of removal work and provide a plan for reinforcing these areas.

(GQAR). Implement additional dust control measures per paragraph GAS, VAPOR, FUME, DUST, SLURRY AND MIST CONTROL IN POWERHOUSE for work inside the powerhouse.

SECTION 03 60 00.01 26 Page 5

3.4.2 Recommended Procedure

Saw cutting, core-drilling, wire cutting or any combination thereof is the recommended method for the concrete removal to be done as part of this contract. In addition to cutting, chipping or grinding may be used to bring the concrete profile to the final finished grade. When the portion of concrete to be removed is of such a magnitude that it cannot be extracted in a single piece, perform additional cutting to allow the concrete to be removed in several convenient sized sections.

3.4.3 Core Drilling

Prior to core drilling, research the area to avoid and identify existing embedded reinforcing, ground wires, conduit, piping and raceways. Refer to reference drawings to assure drill patterns are likely to miss existing reinforcing, ground wires and conduit. Adjust the drill pattern to miss embedded obstructions. Securely ground all core drilling equipment during cutting operations to avoid electrical shock hazards. Submit Core Drilling

Procedure 60 days prior to commencement of core drilling work for approval;

submit together with Concrete Imaging Report. No core drilling is permitted without COR approval.

3.4.4 Chipping

When required, bring concrete removed by saw cutting, core drilling, or stitch drilling to the final required lines and grades by using lightweight chipping hammers, bush hammers, grinding or other approved means. Perform chipping operations such that the over breakage does not exceed 2 inches or extend below the existing grade.

3.4.5 Existing Concrete Strength

The existing concrete to be removed may be expected to range in strength from about 3,000 to over 6,000 psi. The nominal aggregate size of the concrete is unknown. Zones of honeycomb concrete may also be encountered during the drilling process.

3.4.6 Existing Embedded Items

Embedded items in the path of the concrete cutting or drilling operations may include, but are not limited to:

a. Reinforcing steel and minor embedded steel at various distances from the concrete faces.

b. Steel anchors and form tie backs used in placement of the existing concrete. The number and kind are unknown.

c. Electrical conduit.

d. Ground wires.

3.4.7 Research of Embedded Items and Concrete Imaging

Prior to concrete demolition, research the area to avoid and identify existing embedded reinforcing, ground wires, conduit, piping and raceways.

Refer to as-constructed reference drawings to assure drill patterns are likely to miss existing reinforcing, ground wires and conduit. Research of

SECTION 03 60 00.01 26 Page 6 the area must include concrete imaging techniques such as radiographic imaging, ground penetrating radar, or electromagnetic field detection.

Adjust drill pattern for coring and for anchor installation to miss embedded items and obstructions. Submit a Concrete Imaging Report for approval 60 days prior to commencement of core drilling work; submit with

Core Drilling Procedure, Saw Cutting Procedure, and Concrete Removal and

Disposal Plan. Include the following in the Concrete Imaging Report at a minimum:

a. Description of the findings.

b. Proposed penetration location and purpose of penetration.

c. Show the proposed concrete to be removed on a dimensioned concrete outline drawing of the area.

d. Photo or sketch showing:

(1) Embedded Items.

(2) Proposed penetration location.

(3) Dimensions.

3.4.8 Concrete Cutting Tolerances

a. Accurately locate the concrete cut through the existing concrete.

Locate wire or saw cuts within 1/8-inch of plan dimensions.

b. Accurately locate and drill the core drill holes through existing concrete. Minimize the drill wobble during the drilling operation to assure a true and straight hole meeting specified tolerances.

3.4.9 Quality Control

Establish and maintain a quality control system for the concrete cutting operation. Use a system sufficient to maintain tolerances such that the final concrete cutting conforms to the tolerances outlined in this section of the specifications. The Government reserves the right to inspect this control system to determine if the tolerances are being adhered to, and direct the Contractor to correct and repair any deviations from these tolerances.

3.4.10 Disposal Of Waste Water And Concrete Debris

Use a method in disposing of waste water employed in cutting, washing, and rinsing of concrete surfaces that does not stain, discolor, or affect exposed surfaces of the structure and does not allow waste water to enter the river or reservoir. As some Project drains lead to the river, do not dispose of waste water in Government drains. Disposewaste water as per the written Concrete Removal Plan. Do not allow debris to enter the river or reservoir and include methods to prevent this in the written Concrete

Removal Plan.

3.4.11 Repair Of Concrete Surfaces

Restore concrete surfaces to the required lines and grades shown using a

Government approved method. Submit Repair Procedure of Concrete Surfaces for approval 30 calendar days prior to performing repair. Do not commence repair work without an approved procedure. In the repair procedure, include detailed information on all materials and methods used.

a. If piping, conduit or ground wires are damaged during core drilling or concrete excavation, excavate a sufficient area of the concrete to allow the ground wire, conduit, or piping to be repaired by saw cutting

SECTION 03 60 00.01 26 Page 7 the perimeter of the area to a depth of 1-1/2 to 2 inches, and then complete the remaining excavation needed using hand tools or a bush hammer taking care to preserve embedded reinforcing steel intact.

Repair piping, conduit or ground wires per approved methods.

b. Removal of equipment must leave behind a smooth, level surface at the same grade as the surrounding concrete. Should equipment removal damage the concrete substrate or reveal irregularities that cannot practicably be ground smooth, outline the existing concrete by saw-cutting to prevent over-breakage and remove to a uniform depth of

0.5 to 1.5 inches taking care to avoid damage to embedded reinforcing bar and patch with grout suitable for unconfined concrete repair.

c. In all areas where concrete removal will leave transverse reinforcing steel exposed, coat the reinforcing and the local area around the bar with an approved epoxy coating unless otherwise indicated.

d. Repair any anchor holes made in concrete which are to be abandoned following completion of work with non-shrink grout.

e. Fill annualar space of holes greater than 1 inch in depth with non-shrink grout or with foam insulation and seal with fire rated material per paragraph FIRESTOPPING MATERIALS. Finished surface should be flush and installation remain intact through all reasonable normal usage of the area.

Where heating is required, precautions shall be taken to avoid overheating the metal and it shall be allowed to cool in a manner that will restore the original properties of the metal. Proposed flame cutting of material other than structural steel shall be subject to approval and shall be indicated on shop drawings. Shearing shall be accurate and all portions of the work shall be neatly finished. Corners shall be square and true unless otherwise shown. Re-entrant cuts shall be filleted to a minimum radius of 3/4-inch unless otherwise approved.
