	For metal end sections, care should be taken to ensure the end section has an appropriate connection type per Std. Plan 732.00 that is tight.		For metal end sections, care should be taken to ensure the end section has an appropriate connection type per Std. Plan 732.00 that is tight.

	When jointing a metal FES to thermoplastic pipe, any connection rod or strap used should be placed behind at least one full corrugation. The female bell section does not count as a corrugation. Thermoplastic pipe is flexible and failure to secure the rod or strap behind at least one full corrugation may allow the FES to come loose. Proper installation is essential to ensure that the metal ~~end section~~ stays connected to the pipe and can resist the forces placed on it by flowing water.

	The toe strip staying embedded is important to the long term performance of the ~~MES~~. The fill material used around the toe should be well graded and compacted well enough to protect the toe. If scour is observed after installation, corrective measures should be taken. The toe wall is especially important on the outlet end of safety slopes to do the extra force exerted on the bars by the flowing water.

+Proper installation is important to the long term stability of the flared end section (FES) and they should be installed and backfilled it the same manner required for the pipe. The inspector should ensure the installed FES is properly matched to the surrounding soil grading.   Grading around all FES should slope away from the side of the end section.  When the surrounding soil slopes towards the sides of the end section, it concentrates run off water along the FES which leads to erosion and future maintenance.
