SECTION 02110 1

BUILDING DEMOLITION 2

A. GENERAL 4

REQUIREMENTS OF REGULATORY AGENCIES 6

All demolition work shall be accomplished in accordance with all applicable local, state and federal requirements. 8

ASBESTOS-CONTAINING MATERIALS 10

There are no known asbestos containing materials in the project work areas. If, during removal work, the 12 Contractor discovers any material which he suspects may contain asbestos, he shall immediately notify the Owner 13 and cease work in close proximity to the suspected asbestos-containing material. The Owner will then arrange for 14 the testing and removal of any asbestos-containing materials. If time delays are encountered because of required 15 asbestos removal work, the schedule shall be adjusted accordingly by Change Order. 16

LEAD-BASED PAINT AWARENESS 18

Testing has not been performed on painted surfaces in the project area for lead content. Lead can be present in 20 older painted finishes and the Contractor is hereby advised that a potential for lead hazard exists. 21 The Contractor at his discretion may employ chemical spot testing or other means to identify lead coatings where 23 manual demolition is desirable or prior to any employee task that might subject workers to lead hazards. If lead-24 based paint is discovered, contact the Owner’s representative and comply with Occupational Safety and Health 25 Administration (OSHA), 29 CFR 1926.62. This regulation requires the Contractor to develop work strategies that 26 minimize exposure to lead hazards. 27

OWNERSHIP OF REMOVED MATERIALS 29

All items scheduled to be removed by the Contractor shall become the property of the Contractor, and shall be 31 removed from the site. Material shall not be stored on the site for sale, nor shall the Contractor conduct any sale 32 on the site. 33 The Government reserves the right to remove any other items from the building or site areas prior to the start of 35 demolition by the Contractor and to retain such items as his property. 36

REVIEW OF DEMOLITION SCOPE BEFORE BIDDING 38

The Contractor shall be responsible for performing all work and providing all materials required to achieve the 40 design intent shown on these Drawings. The Government will not be responsible for any additional expense to the 41 Contractor if the conditions causing those expenses could have been discovered in an on-site inspection prior to 42 bid submittal. 43

NOISE CONTROL 45

As noted in Section 1A Special Conditions, the Contractor shall use reasonable consideration in avoiding 47 excessive or unnecessary noise during normal business hours. 48

B. PRODUCTS 50

C. EXECUTION 1

REMOVALS 3

l. Demolish concrete and/or masonry walls in small sections. 5

2. Locate demolition equipment throughout the structure and remove materials so as to not impose 6 excessive loads to supporting walls, floors or framing. 7

3. Remove existing walls, partitions, ceilings, finishes, and other materials where shown or required. 8

4. Remove existing mechanical and electrical items noted for removal. 9

5. Where walls are to be removed next to walls scheduled to remain, the walls shall be sawcut to provide a 10 straight edge. 11 The Contractor shall be responsible for providing all necessary temporary shoring and supports as required during 13 removal of existing walls, floors, and other structural items and until final structural replacement items are in place. 14 He shall be responsible for any damage to existing facilities which are scheduled to remain caused by his 15 demolition operations. The Government will not be responsible for any problems or accidents which occur 16 because of the Contractor's failure to thoroughly inspect the structure and review the Drawings of the existing 17 building before removing such items. A copy of the Government’s Drawings of the existing building is available for 18 review at the office of the Government Construction Representative during construction of the project. These 19 Drawings may be helpful to the Contractor in determining the sequence or methods of removal for certain items. 20 The Contractor shall be responsible for verifying the accuracy of such existing Drawings before making decisions 21 regarding demolition based upon them. 22 Dispose of rubbish, debris and material resulting from demolition and removal operations to an offsite area within a 24 maximum of two weeks from the date of the removal from its original installation. 25
