503 EM 385-1-1 Sections 20-26

This is a USACE debris removal disposal after the completion a demolition project.

Debris generated by demolition or contained within the facility or found within the defined work perimeter of the facility or project must be removed from the site as waste material, to include ACM and ORM. Debris must be separated according to type of disposal that is required.
The disposal site, whether Government furnished, private, or commercial must be approved by the GDA prior to Notice to Proceed. Contractor must provide to the GDA documentation that confirms the disposal location, the type of debris, and quantities of each type.

Masonry walls, or sections of masonry, must not be permitted to fall upon the floors of the building in such masses as to exceed the safe carrying capacities of the floors.
Wall sections that are more than 6 ft (1.8 m) in height must not be permitted to stand without lateral bracing, unless such wall was designed and constructed to stand without such lateral support and is in a condition safe enough to be self-supporting. Wall sections must not be left standing without lateral bracing any longer than necessary for removal of adjacent debris interfering with demolition of the wall.

Exception: For wall sections that are designed and constructed to stand without lateral support, an exception may be allowed.

Employees must not be permitted to work on the top of a wall when weather constitutes a hazard.

Structural or load-supporting members on any floor must not be cut or removed until all stories above such a floor have been demolished and removed. This must not prohibit the cutting of floor beams for the disposal of materials or for the installation of equipment, providing the requirements of in this Section are met.
Floor openings within 10 ft (3 m) of any wall being demolished must be planked solid, except when employees are kept out of the area below.
In buildings of skeleton-steel construction, the steel framing may be left in place during the demolition of masonry. Where this is done, all steel beams, girders, and structural supports must be cleared of all loose material as the masonry demolition progresses downward.
Walls that serve as retaining walls to support earth or adjoining structures must not be demolished until such earth has been braced or adjoining structures have been underpinned. > See Section 23.B.04.
Walls must not be used to retain debris unless capable of safely supporting the imposed load.

23-4. If a wall is not properly designed and safe to stand without lateral support, when is lateral bracing required to support the wall?

When the wall is more than 4 ft (1.2 m) in height

When the wall is more than 6 ft (1.8 m) in height

When the wall is more than 8 ft (2.4 m) in height

When the wall is more than 10 ft (3.0 m) in height
