Inspections. Inspections by the municipality will, at a minimum,
be made of the subgrade, formwork, supports, and reinforcement prior
to placement of the concrete, and of the concrete prior to backfilling.
Support pipes, valves and fittings at the required elevation with
brick or concrete block. Do not use earth, rock, wood, or organic
materials as supports.
Place concrete utilizing all possible care to prevent displacement
of pipes or fittings. Return displaced pipes or fittings to line and
grade immediately.
