Standard depth of cover is 5 meters (10 meter design available upon request). Use intermediate sections between top and bottom sections of 1-S manhole to meet drop manhole invert requirements. Where rim/grade elevation to invert is less than the minimum shown, the City of Calgary requires a complete top and bottom to be used, in which case it must be lowered and field benched to invert. Elsewhere, a top half 1-S plus a base slab may be used, subject to approval by the project engineer. Top and bottom half walls taper from the thickest point at the top/base to the center (dimension ‘E’). This may affect mounting of equipment, gates, etc. manhole and catch basin material LAFARGE PIPE eMANUAL PAGE 27
