3. Locate top of bank and the edge of water at the control elevation and plot location on a
drawing at the same scale as the construction drawings.
D. Roadways (N/A)
1. Cross-section elevations at the profile grade line (centerline or edge of median) and at the
edge of pavement at the following frequencies:
a. Major Roads (collector or higher): At high and low points of the profile grade and at
even 100 foot stations in-between.
b. Local Roads: At high and low points of the profile grade.
2. Location of utilities and miscellaneous structures encountered which are different from or not
shown on the Drawings.
3. Spot elevations in parking lots and access roads.
E. Wastewater (N/A)
1. Invert elevations in manholes and at end of stubouts.
2. Distance between manholes.
3. Top of manhole elevations.
4. Location of manholes, based on stationing system on Drawings.
5. Calculate slope of gravity mains.
6. Locate end of stubouts and services by stationing and offsetting from the gravity main and
downstream manholes.
7. Length of stubouts.
8. Elevations of the top slab, wet well invert, influent pipe inverts, and driveway for lift stations.

shown on the Drawings.
11. Top of force main elevations and finished grade at 100 foot intervals and at high and low
points.
12. Locate force main fittings, valves, air release structures, etc. by stationing and offsetting from
gravity wastewater manholes. If manholes are not located nearby, use reference points shown
on the Drawings.
