B. DESCRIPTION OF BIDDING SCHEDULE ITEMS

1. Bidding Schedule item "Demolition" includes the following:

a. Proceed with selective demolition systematically, from higher to lower level. Complete se-lective demolition operations above each floor or tier before disturbing supporting members on the next lower level as shown on the drawings.

b. 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. Use hand tools or small power tools designed for sawing or grinding, not hammering and chopping.

Temporarily cover openings to remain.

c. Cut or drill from the exposed or finished side into concealed surfaces to avoid marring ex-isting finished surfaces.

d. Do not use cutting torches until work area is cleared of flammable materials. At con-cealed spaces, such as duct and pipe interiors, verify condition and contents of hidden space before starting flame-cutting operations. Maintain portable fire suppression de-vices during flame-cutting operations.

e. Maintain fire watch during, and for at least two-hours after flame-cutting operations.

f. Maintain adequate ventilation when using cutting torches.

g. Remove decayed, vermin-infested, or otherwise dangerous or unsuitable materials and promptly dispose of them off-site.

h. Remove structural framing members and lower to ground by method suitable to avoid free-fall, and to prevent ground impact or dust generation.

i. Locate selective demolition equipment and remove debris and materials so as not to impose excessive loads on supporting walls, floors, or framing. Dispose of demolished items and materials promptly.

j. Conduct selective demolition and debris-removal operations to ensure minimum interfer-ence with roads, streets, walks, walkways, and other adjacent occupied and used facili-ties.

k. Concrete: Demolish in small sections. Using power-driven saw, cut concrete to a depth of at least ¾-inch (19-mm) at junctures with construction to remain. Dislodge concrete from reinforcement at perimeter of areas being demolished, cut reinforcement, and then remove remainder of concrete. Neatly trim openings to dimensions indicated.

l. Concrete: Demolish in sections. Cut concrete full depth at junctures with construction to remain and at regular intervals using power-driven saw, and then remove concrete be-tween saw cuts.

m. Masonry: Demolish in small sections. Cut masonry at junctures with construction to re-main, using power-driven saw, and then remove masonry between saw cuts.

n. Concrete Slabs-on-Grade: Saw-cut perimeter of area to be demolished, and then break up and remove.

o. Resilient Floor Coverings: Remove floor coverings and adhesive according to recom-mendations in RFCl's, "Recommended Work Practices for the Removal of Resilient Floor Coverings". Do not use methods requiring solvent-based adhesive strippers.

p. Refrigerant: Before starting demolition, remove refrigerant from mechanical equipment ac-cording to 40 CFR 82 and regulations of authorities having jurisdiction.

q. Verify that utilities have been disconnected and capped before starting selective demolition operations.

r. Review project record documents of existing construction or other existing conditions and hazardous material information provided by the COR. Western does not guarantee that the existing conditions are the same as those indicated in project record documents.

s. Verify that hazardous materials have been remediated before proceeding with building dem-olition operations.

t. Comply with governing EPA notification regulations before beginning selective demolition.

Comply with hauling and disposal regulations of authorities having jurisdiction.

u. Comply with ASSE A 10.6 and NFPA 241.

v. Maintain existing building structure (including structural floor and roof decking) and envelope exterior skin and framing, excluding window assemblies and non-structural roofing material, not indicated to be demolished; do not demolish such existing construction beyond indicated limits.

w. Maintain existing interior non-structural elements (interior walls, doors, floor coverings, and ceiling systems) not indicated to be demolished; do not demolish such existing construction beyond indicated limits.

x. Maintain existing non-shell, non-structural components (walIs, flooring, and ceilings) not in-dicated to be demolished; do not demolish such existing construction beyond indicated lim-its.

y. Unless otherwise indicated, demolition waste becomes the property of the Contractor.

z. Historic items, relics, antiques, and similar objects including, but not limited to, corner-stones and their contents, commemorative plaques and tablets, and other items of inter-est or value to Western that may be uncovered during demolition remain the property of Western. Carefully salvage in a manner to prevent damage and promptly return to the

COR.

2. Bidding Schedule item “Miscellaneous Items" includes the following:

Notify warrantor on completion of selective demolition, and obtain documentation verifying that existing system has been inspected, and warranty remains in effect.

Documentation shall be submitted prior to project close-out and final billing.

c. Temporary protection.
