Field-cut vertical and horizontal steel to maintain a clearance of at least 2 in [50 mm] vertically and horizontally around the pipe.
617.5MEASUREMENT and PAYMENT
1 The engineer will measure Cut-Off Wall (Conc) and Head Wall (Conc) by the cubic yard
[cubic meter], using the neat lines specified for the computed volume of concrete. Volumes occupied by reinforcing steel and anchor bolts will not be deducted from the concrete volume. The volume occupied by the pipe’s outside diameter will be deducted. 2 When a head wall consists of a cut-off wall portion and slope paving, the entire installation
will be measured as a Head Wall (Conc). 3 The department will pay as follows: 4 Grade fill slopes to match head wall, cut-off wall, or both.
