a. If combustible material cannot be removed, provide fireproof blankets to cover such materials.

6. Where possible, furnish and use baffles of metal or gypsum board to prevent the spraying of sparks or hot slag into surrounding combustible material.

7. Prevent the extension of sparks and particles of hot metal through open windows, doors, holes, and cracks in floors, walls, ceilings, roofs, and other openings.

8. Inspect each location of the day's work not sooner than 30 minutes after completion of operations to detect hidden or smoldering fires and to ensure that proper housekeeping is maintained.

12.4 HISTORIC TREATMENT PROCEDURES

Retain or revise paragraphs and subparagraphs in this Article to suit type of treatment required for Project. 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" Article in the Evaluations. 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. This could be a piece-by-piece decision during construction.

Paragraphs in this Article establish a general decision hierarchy. Contractor should be informed about what will be expected to prevent every minor issue from becoming a Change Order. Compliance with these provisions may depend on the extent to which items can be repaired.

First paragraph below is a description of the principal aim of preservation work; edit to suit Project. Note that descriptions will vary for restoration and rehabilitation. Reconstruction is a special circumstance not requiring procedures below.

A. The principal aim of preservation work is to halt the process of deterioration and stabilize the item's condition, unless otherwise indicated. Repair is required where specifically indicated. The following procedures shall be followed:

1. Retain as much existing material as possible; repair and consolidate rather than replace.

2. Use additional material or structure to reinforce, strengthen, prop, tie, and support existing material or structure.

3. Use reversible processes wherever possible.

4. Use traditional replacement materials and techniques. New work shall be distinguishable to the trained eye, on close inspection, from old work.

5. Record the work before the procedure with preconstruction photos and during the work with periodic construction photos.

B. Prohibit smoking by personnel performing work on or near historic structures.

C. Obtain Contracting Officer’s review and written approval in the form of a Constructive Change Directive or Supplemental Instruction before making changes or additions to construction or removing historic materials.

D. Notify Contracting Officer of visible changes in the integrity of material or components whether due to environmental causes including biological attack, UV degradation, freezing, or thawing; or due to structural defects including cracks, movement, or distortion.

1. Do not proceed with the work in question until directed by Contracting Officer.

Delete first paragraph below if no information is provided or available that allows accurate duplication.

E. Where missing features are indicated to be repaired or replaced, provide features whose designs are based on accurate duplications rather than on conjectural designs, subject to the approval of the Contracting Officer’s Representative and Historic Treatment Specialist.

F. Where Work requires existing features to be removed, cleaned, and reused, perform these operations without damage to the material itself, to adjacent materials, or to the substrate.

G. Identify new or replacement materials and features with inconspicuous, permanent marks to distinguish them from original materials. Record the legend of identification marks and the locations of these marks on Record Drawings.

H. When cleaning, match samples of existing materials that have been cleaned and identified for acceptable cleaning levels. Avoid overcleaning to prevent damage to existing materials during cleaning.

If other types of materials must be removed, insert requirements here.

USDA FOREST SERVICE, R-4

SWAN VALLEY RESTORATION

SECTION 017320 - SELECTIVE DEMOLITION

PART 13 - GENERAL

13.1 SUMMARY

13.5 PROJECT CONDITIONS

A. Government will occupy portions of building immediately adjacent to selective demolition area. Conduct selective demolition so Government operations will not be disrupted. Provide not less than 72 hours' notice to CO of activities that will affect Government operations.

B. Maintain access to existing walkways, corridors, and other adjacent occupied or used facilities.

1. Do not close or obstruct walkways, corridors, or other occupied or used facilities without written permission from authorities having jurisdiction.

SPEC WRITER: RETAIN PARAGRAPH AND SUBPARAGRAPHS ABOVE AND DELETE FIRST PARAGRAPH AND SUBPARAGRAPHS BELOW IF ASBESTOS IS PRESENT AND GOVERNMENT HAS A SEPARATE CONTRACT TO ABATE ASBESTOS BEFORE SELECTIVE DEMOLITION BEGINS.

C. Hazardous Materials: Hazardous materials are present in building to be selectively demolished.

1. Hazardous material remediation is specified elsewhere in the Contract Documents.

2. Do not disturb hazardous materials or items suspected of containing hazardous materials except under procedures specified elsewhere in the Contract Documents.
