For specific retaining wall types, include the following additional information on the layout and in the plan set.

Spread Footing Walls.

For spread footing walls, include the following additional information:

Panel design designation (for example, LC-10-32) for each panel corresponding to the appropriate cast-in-place spread footing wall standard sheet. The designation includes a reference to the controlling standard drawing, design height, and panel width information.
Location of expansion and construction joints (Assuming 32-ft. panels, every third joint is typically designated as an expansion joint.)
Set bottom of wall (top of footing) horizontal and stepped to meet minimum embedment criteria. (Distance from one step to the next is typically greater than 6 in. Provide bottom of wall elevations for all panels.)
Appropriate standard sheets pertaining to cast-in-place spread footing walls

Designate all information necessary for the contractor to construct the wall on retaining wall layouts for spread footing walls. This type of wall does not have a proprietary vendor to provide shop drawings, so the plan set must be complete with details.

Mechanically Stabilized Earth (MSE) Walls.

For MSE walls, include the following additional information:

Bottom of wall shown following the proposed finished grade offset at the minimum embedment depth specified
The most recent
Mechanically Stabilized Earth Panel Type Systems
list (include it in the general notes of the plan set.) Appropriate standard sheets pertaining to MSE walls

Concrete Block Walls.

For concrete block walls, include the following additional information:

Bottom of wall shown following the proposed finished grade offset at the minimum embedment depth specified
The most recent
Concrete Block Retaining Wall Systems
list (include it in the general notes of the plan set.) Appropriate standard sheets pertaining to concrete block walls

Tied-Back Walls.

For tied-back walls, include the following additional information:

Panel and closure-pour width dimensions
Bottom of wall shown with a level footing elevation, also referred to as having steps. (Distance from one step to the next is typically greater than 6 in.)

Designate all information necessary for the contractor to construct the wall on retaining wall layouts for tied-back walls. This type of wall does not have a proprietary vendor; however, shop drawings are required to fully detail the panel schedule to be used on the project and information regarding proposed anchor length.

Soil/Rock Nailed Walls.

For soil or rock nailed walls, include the following additional information:

Location of expansion and construction joints spaced at intervals not to exceed 90 ft.
Set bottom of wall horizontal and stepped to meet minimum embedment criteria. (Distance from one step to the next is typically greater than 6 in. Provide bottom of wall elevations for all panels.)
Estimated quantity for “Soil/Rock Nail Anchors”
Typical section showing existing or proposed foundations or other obstructions that may interfere with wall construction
Test nail lengths, loads, and bar grade and size

Designate all information necessary for the contractor to construct the wall on retaining wall layouts for nailed walls. This type of wall does not have a proprietary vendor to provide shop drawings, so the plan set must be complete with details.

Drilled Shaft Walls.

For drilled shaft walls, include the following additional information:

Set bottom of wall horizontal and stepped to meet minimum embedment criteria
Panel width dimensions
Bottom of wall shown with a level footing elevation, also referred to as having steps. (Distance from one step to the next is typically greater than 6 in. Provide bottom of wall elevations for all panels.)
Estimated quantity for “Drilled Shaft” used on wall (This quantity is broken into specified shaft diameters.)

Designate all information necessary for the contractor to construct the wall on retaining wall layouts for drilled shaft walls. This type of wall does not have a proprietary vendor to provide shop drawings, so the plan set must be complete with details.

Temporary MSE Walls.

For temporary MSE walls, include the following additional information:

Bottom of wall shown following the proposed finished grade offset at the minimum embedment depth specified
Appropriate standard sheets pertaining to temporary MSE walls
