First and foremost, you need to be certain that the pad is level, as installing your manhole on uneven ground can lead to big problems in the future. Also, you need to make sure the pad is large enough that it can accommodate the manhole, primary flow management device and any connectors. After the forming the pad, pour in the concrete and make sure that it is smooth and level.
