PART 3 EXECUTION
3.1PREPARATION
A.General
1.Perform all work within the limits of the Department right of way
unless written agreements are in place with adjacent property owners.
2.Complete backfill and embankment placement over the pipe before
concrete lining.
3.Provide the necessary controls to prevent pollutants from
being transported downstream.
4.Verify host pipe internal diameter and length before ordering
concrete.
B.Host Pipe Cleaning
1.Remove material to include sediment, rocks, and miscellaneous
debris in order that an inspection and concrete lining can be properly performed.

2.Use a cleaning method and tools that will not cause damage to the
pipe or surrounding roadway features.
a.Notify the Engineer when cleaning could result in damage.
b.Do not cause erosion of surrounding areas from cleaning
operations.
c.Minimize sediment from being transported downstream.
3.Collect and properly dispose of all material removed.
C.Host Pipe Inspection:
1.Perform a visual inspection
2.Inspect the condition of the host pipe and the suitability of the
concrete lined invert installation. Document and notify the Engineer of the following:
a.Collapsed or impassable sections of the pipe
b.Horizontal and vertical alignment deviations
c.Structural concerns
d.Loss of material surrounding the pipe exterior
e.Infiltration of water
f.Repairs required to perform the installation
3.2PLACEMENT
A.Shape and support the welded wire reinforcement to provide 1 inch
clearance from the crest of the metal corrugations.
B.Place concrete at least 4 inches above the crest of the corrugations and to
a width one third of the circumference of a round pipe or the maximum span of an arch pipe.
1.Control the thickness of the concrete by installing non-corrosive
pins, nails, or other gauging devices into the crest of the corrugations, perpendicular to the surface.
C.Finish the concrete to a floated surface finish according to Section 03310.
D.Cure concrete according to Section 03390.
1.Provide a minimum of 48 hours before allowing water to flow
through the pipe after applying the curing compound.
E.Provide adequate control of water in the host pipe when necessary.
1.Repair damage caused as a result of flow control or lack thereof
