Notes:
1) 1-S manholes are NOT prebenched.
2) Non standard hole sizes and angle entry holes
available.
3) Lifting clutches available.
4) Standard depth of cover is 5 m. 10% extra
for deeper cover.
5) Use intermediate sections between top and
bottom sections of 1-S manhole to meet drop manhole
invert requirements.
6) Where design invert to rim is less than the
minimum shown, the City of Calgary requires a
complete top and bottom 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 Contractor obtaining project
engineer's approval.
7) 1-S skimming manholes available in all sizes
at same price.
