Installation 1. Refer to approved plans for location, extent, and construction details. If there are questions or problems with the location, extent, or method of installation, contact the engineer or responsible on-site officer for assistance. 2. Clear the location for the berm, clearing only the area that is needed to provide access for personnel and equipment. 3. Remove roots, stumps, and other debris and dispose of them properly. 4. Form the berm from the material, and to the dimension specified in the approved plans. 5. If formed from sandbags, then ensure the bags are tightly packed such that water leakage through the bags is minimised. 6. Check the alignment of the berm to ensure positive drainage in the desired direction. 7. Ensure the berm discharges to a stable outlet. 8. Ensure the berm does not discharge to an unstable fill slope. Maintenance 1. Inspect flow control berms at least weekly and after runoff-producing rainfall. 2. Inspect the berm for any slumps, wheel track damage or loss of freeboard. Make repairs as necessary. 3. Check that fill material or sediment has not partially blocked the drainage path up-slope of the embankment. Where necessary, remove any deposited material to allow free drainage. 4. Dispose of any collected sediment or fill in a manner that will not create an erosion or pollution hazard. 5. Repair any places in the berm that are weakened or in risk of failure. Removal 1. When the soil disturbance above the bank is finished and the area is stabilised, the flow control berm should be removed, unless it is to remain as a permanent drainage feature. 2. Dispose of any sediment or earth in a manner that will not create an erosion or pollution hazard. 3. Grade the area and smooth it out in preparation for stabilisation. 4. Stabilise the area by grassing or as specified in the approved plan.
