4.1103.4a
All worker safety specifications will be in accordance with SWS 2.0100 Worker Safety
Lead safety procedures in buildings built before 1978 will be followed, unless approved testing method proves absence of lead based paint in surfaces that will be disturbed
Ensure worker safety, especially in regard to fall protection considerations and contaminants found in demolition, such as asbestos, lead, polychlorinated biphenyls, etc.
4.1103.4b
Occupant will be notified of changes or repairs to be made
An occupant safety plan will be prepared and implemented
Ensure occupant safety
4.1103.4c
Conduct pre-inspection in accordance with SWS 2.0100.4 Worker Safety
Gaps, cracks, and holes in fire separations located within the work area will be visually identified and incorporated into air sealing work scope, including those that span two conditioned or unconditioned spaces
Where drawings are available that identify specific fire-resistance ratings (i.e., 1 hour, 2 hour), materials and methods will be employed to preserve or restore such rating
Where drawings are unavailable or do not identify specific fire-resistance ratings, the fire-resistance rating of the assembly may be inferred from the current construction (i.e., single 5/8 sheetrock, concrete masonry unit), and materials and methods employed will be consistent with restoring or preserving such inferred fire-resistance rating
Repairs necessary to stabilize work areas and protect or preserve the integrity of energy improvement will be completed before work begins
Insulation will not be installed if moisture-related issues are not resolved
Existing water control measures will be identified
Air sealing locations on the exterior walls will be identified
Air sealing will be completed before installing insulation
Identify and remediate pest, moisture, air leakage, and electrical problems before insulation installation
Ensure a durable, continuous
thermal boundary
Thermal boundary
The separation between the interior and exterior environments of a building that slows heat flow
Avoid compromising existing water control system
4.1103.4d
When feasible, insulation will be installed into cavities from the exterior side of the wall
When feasible, exterior cladding at the insulation access point will be removed before creating an access hole through the sheathing
Insulation access point will be created to minimize
air barrier
Air barrier
The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary
and drainage plane disruption
Access point will be sealed to be airtight and watertight after insulation installation before reinstalling the exterior cladding
Water management system will be repaired to function as originally intended (e.g., lapping new felt paper underneath the upper and over the lower joint of the existing felt paper)
Ensure occupant health and safety
Minimize disruption within the units
Avoid compromising existing water control system
Minimize air and moisture flow through the wall system
4.1103.4e
Sealants will be compatible with their intended surfaces and applied in accordance with manufacturer specifications
Selection will be durable, pest resistant, and have a weather-appropriate seal
Indoor sealants will be low volatile organic compound (
VOC
VOC
Volatile organic compound
) products that meet independent testing and verification protocols, such as Green Seal GS-36, "GREENGUARD Children and Schools," or comparable certifications
Fire-resistance-rated assemblies will be provided with sealants permitted by the authority having jurisdiction and adopted building code
Prevent intrusion of moisture and pests into the sealed assembly
Prevent exposing workers or occupants to excessive
VOC
VOC
Volatile organic compound
levels
Ensure sealant meets or exceeds the performance characteristics of the assembly and is compliant with local fire code requirements
4.1103.4f
dense pack
Dense pack
The process of installing loose-fill insulation to reduce air flow and perform to a stated R-value
Using fill tube, 100% of each cavity will be completely filled to a consistent density:
Cellulose insulation used in an enclosed cavity will be installed at 3.5 pounds per cubic foot or greater density Blown fiberglass, mineral fiber, rock and slag wool, or spray foam used in an enclosed cavity will be installed in accordance at or above manufacturer recommended density to limit air flow that corresponds to an air permeance value of 3.5 cubic feet per minute/square feet at 50 pascals, as measured using the following applicable methods:
