NOTE:

1. The horizontal drain work consists of the installation of initial and secondary drains. The approximate locations, orientations, inclinations, and length of the 30 initial drains are shown on

Sheet C.3-4. The CO will provide the locations, orientations, inclinations, and lengths of the secondary drains after the installation of the initial drains.

2.The horizontal drain pipe pay item quantity includes initial and secondary drains.

3.Quantities shown on this sheet are the tabulation of quantities from Sheets C.3-5.

4. Estimated 145 cuyd of structure excavation to install class 5 riprap (Information Only) is not suitable for embankment construction.

5. Estimated 580 cuyd of roadway excavation (Information Only) is not suitable for embankment construction.

HORIZONTAL DRAIN QUANTITIES

1.Horizontal drain azimuth is referenced to grid north.

2.Do not disturb existing test boring instrumentation or wiring.

Verify locations before performing ground disturbing work. A steel extension pipe will need to be fitted to extend the existing steel pipe above the drill pad. Inform the CO 10 days prior to adding the extension and backfilling aroung the existing instrumentation casing near Buttress A.
