Flush mounted boreholes or installations are finished so that the instrumentation is entirely below ground; nothing is left sticking above the ground. This kind of installation is typically done in urban areas, but may be used anywhere.
Step 1 - Plan the Installation
To ensure that you have enough space to work, an underground electrical utility enclosure such as a vault or manhole system should be acquired. You need to determine the minimum capped length for the SAAF and ensure there is enough space to do cable turns and provide strain relief. Conduit should be acquired to protect the communication cable running from the installation to the instrumentation cabinet.

Step 2 - Prepare the Area for Installing the SAAF
Excavate, by hand, an area large enough to install the utility enclosure of choice. You need to ensure the excavation and utility enclosure installation is completed prior to installing the ShapeArray (SAA).
Step 3 - Use an SAA Install Kit to Finish the Installation
Please refer to the Finishing the Installation Process Using the SAA Install Kit guide.

Step 4 - Alternatively, Finish the Installation with a Custom Made Install Kit
Refer to either of the following guides:
- How to Create and Use a Custom SAA Install Kit Using Couplers and Set Screws (Figure 3.A below)
- How to Create and Use an Install Kit Using Slot Cuts and Gear Clamps (Figure 3.B below)
