Division 2 has great potential for waste reduction, depending on the nature of the project. Significant factors in the generation of waste in this division include site clearing, demolition, selective demolition, and repaving.
Testing for and identification of environmental hazards and contaminants should precede all demolition work. Procedures for dealing with hazards such as removal or containment should be specified. Dismantling and separation of materials is critical to demolition waste reduction, as is knowledge of material types and sizes and potential markets. Coordinate closely with drawings.
Use this Section for partial or minor dismantling, recycling, salvage, and reuse. More time given to remodeling design may allow for keeping existing interior walls in place (as opposed to assuming a "gut job"). Careful demolition planning and execution may allow, for instance, covering existing plaster finishes under new, thinner drywall, to reduce waste and resource use, improve acoustic isolation, covers lead-based paints, and increase thermal mass. As local markets grow for salvage and materials for recycling, care taken here may lead to project cost savings.
When waste reduction is a priority, use this Section to specify demolition work to emphasize waste reduction objectives. Coordinate closely with Drawings.
SECTION 02070 SELECTIVE DEMOLITION
PART 1 GENERAL
1.01 DESCRIPTION
Demolition includes cutting of new openings in existing structure as noted on the Drawings and the reuse, salvage, removal and recycling or disposal of the demolished materials.
If the Owner is to do some of the removal and /or salvaging of equipment and materials, add an Article to that effect, identifying items and timing.
1.02 DEMOLITION BY THE CONTRACTOR
Conduct demolition and disposal operations to prevent injury to passersby and the Owner's and adjacent buildings and other facilities. Promptly repair damages caused to adjacent facilities by demolition operations at no cost to the Owner.
Maintain existing utilities in service and protect against damage during demolition operations.
Do not obstruct streets, walks or other occupied or used facilities without permission from authorities having jurisdiction.
1.03 SALVAGE, REUSE & RECYCLING
Reuse and relocate items as shown on the Drawings.
Perform the work of this section in a manner that maximizes salvage and recycling of materials, including the dismantling and removal of the materials listed below. All materials dismantled and removed are to be separated, set aside, and prepared for reuse, as specified, and stored or delivered to collection point for reuse, remanufacture, or recycling, as specified and to the maximum extent economically feasible. Protect and secure all stored materials.
Edit to suit the project contract
All removed materials and equipment not reused and not turned over to the Owner will become the Contractor's property to salvage.
Edit to suit project and location. See the demolition materials checklist for use during plan review or during a walk-through of the structure to be demolished in order to prepare a comprehensive list of materials for insertion in this Section.
See Construction Materials: Management and Markets for a directory of Wisconsin C&D material recyclers.
Concrete (can be crushed and graded for use as riprap, aggregate, sub-base material, or fill).
Brick (can be reused if whole; crushed for use as landscape cover, sub-base material, or fill).
Concrete block (can be reused if whole, crushed for use as sub-base material or fill).
Land clearing wood (can be chipped or shredded for use as ground cover, mulch, compost, pulp, or process fuel).
Whole buildings (can be sold or donated and either moved or dismantled).
Asphalt paving material (can be sorted by type for milling and recycling).
Wood (can be sorted by type and size for reuse or remanufacturing).
Precast concrete panels (can be used for erosion control or landscape features).
Windows and doors (can be salvaged).
Metal (can be separated for recycling).
Hardware (can be salvaged for reuse).
Electrical and plumbing fixtures and fittings (can be salvaged).
Use the following ¶ only if there is a reporting requirement
Maintain an inventory of all removed materials and submit tracking forms for all removed materials indicating type, quantities, condition, destination, and end use.
1.05 DISPOSAL
Remove from the site promptly all debris, rubbish and other materials resulting from demolition operations. Dispose of items which have regulated disposal requirements and are to be removed and disposed of in the manner required by law, including, but not necessarily limited to:
Edit to suit project and location.
Appliances
Fluorescent light ballasts manufactured prior to 1978. (PCB).
Fluorescent lamps. (Mercury).
Glass
Refrigeration, air-conditioning, and other equipment containing refrigerants (CFC recovery).
Batteries. (Lead, acid, mercury).
Newspapers
Plastic containers
Polystyrene
Paints, solvents, and other hazardous fluids.
Corrugated cardboard.
Asbestos based materials.
Materials with lead based finishes.
1.05 CLEANING
If deemed necessary by the governing authorities or the Architect, clean adjacent structures and other improvements of dust, dirt and debris caused by the demolition operations. Return adjacent areas to the condition existing prior to the start of work.
