WebWhere the topping thickness is detailed to be 40mm at the supports, at mid-span the topping thickness will be only be 15mm, if there is a 25mm camber on the planks. Thus to achieve a minimum topping thickness of 40mm at mid-span the topping thickness at the supports needs to be the minimum thickness plus the maximum camber, e.g. 65mm. long term residential care for schizophrenia
