5. Elevation View Speaking Points
The elevation view is a representation of what you would see if you looked horizontally at the face of a wall from a point perpendicular to the wall. The point of view is normally perpendicular to the face thus if the wall bends or curves, the point of view changes so as to always be looking perpendicular to the wall alignment.
It is sometimes called the profile view.

11. Details – Phased Construction
Phased Construction – when the construction space is constrained. It involves building part of a project to a temporary stopping point in a first phase (stage), typically to facilitate maintenance of traffic. The stopping point may be a temporary wall or steep slope constructed with wire mesh facing or a simple geotextile wrap or it may be made from facing panels that get buried during the second phase. Traffic is then relocated onto the newly-built portion and the rest of the MSE wall is constructed. This is becoming more common as more work is performed in urban areas.
This is a Power point slide to identify the stage construction.

13. Details - Two-Stage MSE Wall
A two stage wall is a special case of phased construction. It involves construction of a temporary wall with a very flexible facing to accommodate large anticipated settlements. After the settlement is complete, the finished facing is installed in front of the temporary face. The finished facing may be cast in place as shown in this photo or may consist of precast panels, tilt up panels, modular blocks, and other facings. Details will include the method of attaching the finished facing to the temporary structure.
This is a typical MSE wall constructed in two stages.

For Modular block walls, reliance is placed on field cutting and fitting the individual blocks to fit the general layout shown.

Assembly details for Modular block.
Modular blocks are usually assembled with the assistance of connectors, pins, or special recesses in the blocks that help maintain the alignment of each row of blocks. Though these connectors also secure the reinforcing, the friction between the blocks and the reinforcing helps to develop the connection strength.

This detail for a catch basin behind a modular block wall has four important elements.
Primary reinforcing is terminated at the back of the catch basin.
Secondary reinforcing is placed in a wrapped face configuration to form a self supporting wall behind the catch basin.
Styrofoam is placed to reduce earth pressure on the catch basin by allowing the wrapped face wall to deform slightly.
The facing blocks are grouted together with steel reinforcing pins to make it a solid unit. Note it supports no soil loads in the area in front of the catch basin.
This is typical catch basins within different types of MSE wall

93. Cutting of Reinforcement
The partial cutting of geogrid type reinforcements or welded steel grids will reduce the reinforcement strength. However, this may be allowed by the design document. Inspectors should check with the approved shop drawings and design documents (including project special provisions) to see if cutting is allowed. In some cases there may be limitations on cutting.
This picture shows examples of cut reinforcement that severely compromises the strength of the reinforcement.
In the top picture the reinforcement is laid out at an elevation well below the connection point to the wall. If additional fill is to be placed beneath it the transverse bar in front of the pile may limit the ability to remove all the slack from the reinforcement prior to back fill.
In the lower picture, all of the longitudinal bars have been cut due to the orientation of the two piles leaving no longitudinal bars to transmit the reinforcement load. This is a case where the inspector should contact the designer to clarify just how much of the reinforcement can be cut in a specific location.
This is a Power point slide indicating the cutting of reinforcements
Speaking Points
Geogrid reinforcement may be cut to go around deep foundations.
Cutting the reinforcement reduces the strength of the reinforcement and should only be done if specifically permitted on the drawings
These are BAD examples of cut reinforcement.
Note that the bottom picture has no remaining continuous longitudinal strands so the entire width of reinforcement is compromised.
In the top picture the transverse bar in front of the pile will likely limit the ability to remove any slack from the reinforcement when it is placed at the proper elevation
