The work also includes cleaning of reinforcing steel, blast cleaning of all rust and loose materials and removal and disposal of debris.

3.2 DEMOLITION

A. Demolition Requirements:

1. The extent of demolition will be determined in the field by the Contractor and approved Engineer.

2. The demolition payment for unit priced items will be included in the unit price for patching. The payment will include all labor and materials for sounding and marking of deteriorated concrete surface, removal of concrete, cleaning of demolished surface and reinforcement, removal of rust and loose materials, cleanup and removal of debris, overhead, profit, etc. No payment will be made for concrete removed beyond the limits approved by the Engineer or testing agency.

3. Any damage that results from the Contractor's operation to existing structures not to be demolished shall be repaired by the Contractor to the satisfaction of the Engineer, all at the Contractor's expense.

4. Concrete will not be demolished beyond a depth of three (3) inches for beams or floor slabs without the prior written approval of the Engineer. If depth of demolition exceeds three (3) inches for beams and floor slabs, temporary emergency shoring may be required. Provide temporary shoring as approved by the Engineer before proceeding with demolition.

5. Repair concrete as soon after demolition as practical. Follow criteria shown on the plans for extent and maximum depth limits of demolition at any time. The Engineer may require suspension of demolition operation if the areas already demolished are not repaired satisfactorily within the time specified.

D. Demolition Method and Operation:

1. All demolition shall be performed to the depths and limits as shown on the plans, schedules and notes, and as approved by the Engineer. Demolition shall be accomplished by the conventional methods described herein.

2. Prior to starting demolition, all concrete surfaces and areas assumed to be deteriorated shall be delineated by visual examination and by sounding the concrete surface. Sounding of the surface should be performed by the Contractor and approved by the Engineer. The contractor must provide documentation that they are experienced in this type of work prior to acceptance by the Engineer. Sounding of concrete surfaces shall be performed in the presence of the Engineer, who shall approve the inspection agency's determination of the limits of deterioration. This requirement may be waived at the discretion of the Engineer.

Repairs Project

SECTION 03 31 10 – CONCRETE DEMOLITION AND REPAIR - 4

3. The Contractor shall mark the outline of the deteriorated concrete by using non-washable paint or other approved marking material. Isolated cracks requiring repair shall also be delineated by the Contractor. A different paint outline shall be provided to delineate the recommended patch area outside the deteriorated concrete perimeter as required by the contract drawings.

4. All deteriorated concrete shall be removed to sound concrete with a 15-lb. (maximum) pneumatic hammer with points which do not exceed the width of the shank or by the use of hand picks or chisels as required and as directed. Irregularly shaped or rounded corners shall be square by saw cutting or chipping. Care shall be taken not to cut or damage any reinforcing. No existing reinforcing steel shall be cut or removed without the written approval of the Engineer. Existing concrete will not be removed more than that required to expose the surface of the sound concrete, except where required as shown on the drawings. All surfaces left by the removal of deteriorated concrete shall be nearly horizontal or vertical.

5. If additional concrete deterioration beyond the limits shown on the plans or as determined by preliminary examination is found during the demolition operation, the Engineer shall be notified and a written approval obtained prior to proceeding with the work.

6. If sound concrete is encountered before existing reinforcing steel is exposed, the surface shall be prepared and repaired without further removal of the concrete. However, if the reinforcing steel is wholly or partially exposed then the deteriorated and/or sound concrete shall be removed to a minimum clearance one (1) inch all around the reinforcing steel.

7. Demolition for cracks outside spalled areas shall be accomplished with a mechanical router. Geometry of notch shall conform to the requirements of the contract drawings.

8. All exposed concrete surface and existing reinforcing steel in areas of repair shall be cleaned to remove all debris, loose concrete, loose mortar, rust, scale, etc. Exposed reinforcing steel surface facing away from sandblast nozzle shall be cleaned with a wire brush to remove all rust and loose particles.

9. The Engineer shall inspect existing reinforcing steel for section loss after rusted steel is cleaned in accordance with Section 8 above. If greater than 10% of the cross-sectional area is lost, new rebar to match the existing rebar in size shall be spliced to the existing rebar. In order to accommodate the splice, a sufficient length of existing rebar must be exposed. If required, additional demolition may be necessary.

10. All material removed shall become the property of the Contractor and shall be disposed of offsite.

3.3 CONCRETE REPAIR

A. Surface Preparation: After the demolition is completed and the surface has been tested for soundness, the exposed steel shall be thoroughly cleaned by sandblasting and incorporated into new concrete patch. A 3000 psi water blast shall be used to clean the surface of dust and to wet the surface for application of repair materials. The prepared surface shall be free of all substances and contaminants that would inhibit a good bond.

B. Supplemental Reinforcement: After existing reinforcement is blast cleaned, any rebar that has lost 10 percent or more of its original cross-sectional area shall be supplemented or replaced with supplemental reinforcement as directed by the Engineer. Where required, position, support and secure reinforcement against displacement.

Locate and support with wire ties, spacers, supports, and other devices necessary to install and secure the reinforcing properly. Set wire ties so ends are directed into concrete, not toward exposed concrete surfaces.

C. Concrete Repair: In general, spalled concrete shall be repaired by formed and pumped or formed and cast repair mortar as indicated on the drawings.

3.4 FORMS

A. Formwork: Construct so that concrete members and structures are of correct size, shape, alignment, elevation and position. Construct forms to be watertight to prevent leakage during concrete or repair mortar placement.

B. Provide openings in formwork to accommodate inlet and outlet ports and pressure valves. Accurately place and securely support items built into forms.

Repairs Project

SECTION 03 31 10 – CONCRETE DEMOLITION AND REPAIR - 5

C. Clean and adjust forms prior to concrete placement. Apply form release agents or wet forms, as required.

Re-tighten forms during concrete placement if required to eliminate mortar leaks.

3.5 CONCRETE CURING AND PROTECTION

A. Curing: Cure formed surfaces by moist curing until forms are removed. Provide protection as required to prevent damage to exposed concrete surfaces. Allow moist curing to occur for a minimum of seven days.
