3.02 HISTORIC TREATMENT PROCEDURES

A. It may not be feasible to identify in the Contract Documents precisely how and to what extent each feature should be treated, such as which elements are to be repaired and which elements replaced. Refer to the “Definitions” section of this Section. The need for stabilizing and repairing in place will be determined, in some cases, during the course of the work. If it is discovered that stabilizing or repairing is not feasible, replacement is allowed with the approval of the CO.

3.02 PREPARATION

A. Site Access and Temporary Controls: Provide temporary barricades and other protection required to prevent injury to people.

B. Temporary Shoring: Provide and maintain interior and exterior shoring, bracing, or structural support to preserve stability and prevent movement, settlement, or collapse of construction to remain, and to prevent unexpected or uncontrolled movement or collapse of construction being demolished.

3.03 POLLUTION CONTROLS

A. Dust Control: Use temporary enclosures, and other suitable methods to limit spread of dust and dirt. Comply with governing environmental-protection regulations.

1. Wet mop floors to eliminate trackable dirt. Wipe down walls and doors of demolition enclosure. Vacuum carpeted areas.

B. Cleaning: Clean adjacent structures and improvements of dust, dirt, and debris caused by selective demolition operations. Return adjacent areas to condition existing before selective demolition operations began.

3.04 SELECTIVE DEMOLITION

A. General: Demolish and remove existing construction only to the extent required by new construction and as indicated. Use methods required to complete the Work within limitations of governing regulations.

1. Neatly cut openings and holes plumb, square, and true to dimensions required.

Use cutting methods least likely to damage construction to remain or adjoining construction.

2. Cut or drill from the exposed or finished side into concealed surfaces to avoid marring existing finished surfaces.

3. Locate selective demolition equipment and remove debris and materials so as not to impose excessive loads on supporting walls, floors, or framing.

4. Dispose of Demolished items and materials promptly.

B. Removed and Reinstalled Items:

1. Clean and repair items to functional condition adequate for intended reuse. Paint equipment to match new equipment.

2. Pack or crate items after cleaning and repairing. Identify contents of containers.

3. Protect items from damage during transport and storage.

June, 10 Big John Rehabilitation 024119 - 4

4. Reinstall items in locations indicated. Comply with installation requirements for new materials and equipment. Provide connections, supports, and miscellaneous materials necessary to make item functional for use indicated.

C. Existing Items to Remain: Protect construction indicated to remain against damage and soiling during selective demolition. When permitted by CO, items may be removed to a suitable, protected storage location during selective demolition. Clean and reinstalled removed items in their original locations after selective demolition operations are complete.

3.05 CUTTING, PATCHING, AND REPAIRS

A. General:

1. Promptly repair damage to adjacent construction caused by selective demolition operations.

2. Employ skilled workers to perform cutting, patching, and repairs.

B. Protection: Protect existing construction during cutting, patching, and repairs to prevent damage. Provide protection from adverse weather conditions for portions of project that might be exposed during cutting, patching, and repair operations.

C. Adjoining Areas: Avoid interference with use of adjoining areas or interruption of free passage to adjoining areas.

D. Existing Services: Where existing services are required to be removed, relocated, or abandoned, bypass such services before cutting to minimize interruption of services to occupied areas.

E. Cutting: Cut existing construction by sawing, drilling, breaking, chipping, grinding, and similar operations, using methods least likely to damage elements retained or adjoining construction.

1. Provide temporary support of work to be cut.

2. In general, use hand or small power tools designed for sawing and grinding, not hammering and chopping. Cut holes and slots as small as possible, neatly to size required, and with minimum disturbance of adjacent surfaces. Temporarily cover openings when not in use.

3. Existing Finished Surfaces: Cut or drill from the exposed or finished side into concealed surfaces.

4. Proceed with patching after construction operations requiring cutting or repairs are complete.

F. Patching: Patch construction by filling, repairing, refinishing, closing up, and similar operations following performance of other Work. Patch with durable seams that are as invisible as possible. Provide materials and comply with installation requirements specified in other Sections of these Specifications.

G. Repairs: Where repairs to existing surfaces are required, patch to produce surfaces suitable for new materials.

1. Completely fill holes and depressions in existing masonry walls that are to remain with an approved masonry patching material applied according to manufacturer's written recommendations.

June, 10 Big John Rehabilitation 024119 - 5

H. Finishes: Restore exposed finishes of patched areas and extend restoration into adjoining construction in a manner that eliminates evidence of patching and refinishing.

I. Ceilings: Patch, repair, or rehang existing ceilings as necessary to provide an even planed surface of uniform appearance.
