Written by GovTribe AI · Apr 3, 2024

This document contains Oregon Standard Drawings for a state and local contract opportunity related to the US20 MP 2.9 Rock Fall Barrier (Newport) Project in Marion County and the City of Salem, Oregon.

The drawings provide detailed specifications and requirements for the installation of precast concrete barriers, including median barriers, shoulder barriers, and methods for securing the barriers to the roadway. The drawings cover reinforcement, dimensions, connections, and other technical details. The contract opportunity is for the construction of this rock fall barrier project, which appears to have an effective date of June 1, 2022 to November 30, 2022. No specific bid due date or award information is provided in the document.

METHODS OF SECURING CONCRETE BARRIER TO ROADWAY

GENERAL NOTES FOR ALL DETAILS ON THIS SHEET:

1. This standard drawing is intended to show acceptable methods of securing concrete barrier to roadway.

2. Secure concrete barrier to roadway when any of the following conditions exist:

a) Barrier deflection requirements per Std. Dwg. RD500 cannot be obtained, or

b) When required by plans, or

c) As directed by the Engineer.

3. Select one of the securing methods shown.

For details not shown, see the standard drawing(s) referenced for the selected method.

4. Securing concrete barrier to roadway is in addition to connections between adjacent concrete barrier sections, bridge rails, retaining walls, and similar existing or constructed objects.

5. Temporary concrete barrier to be precast concrete median barrier with pin and loop assembly.

6. Precast concrete barrier used in medians less than 8' in width (as measured between nearest fog lines) shall be secured to roadway to resist impacts from both sides.

7. Anchor rods are standard barrier pins, modified for shoulder installation, as shown.

8. Normal permanent installation of concrete barrier is on top of finish grade, to provide 3" vertical reveal. Modify placement when required by plans, or as directed.

9. All pins, bolts, dowels, loop bars, and connectors shall be hot-dip galvanized after fabrication.

GENERAL NOTES FOR ALL DETAILS ON THIS SHEET:

1. Normal use assumes an existing established slope. This detail is not intended for construction of new slope steeper than a slope of 1V:2H.

2. If the slope is flatter than 1V:1H ensure that there is a clear recovery area behind the barrier, with no funneling effect to the back of the obstruction.

3. Provide drainage as required.

4. See Std. Dwgs. RD500, RD510 and RD516 for details not shown.

5. Surfacing details same as adjacent shldr.

6. Barrier sections, connections and appurtenances that retain backslope require stability design calculations stamped by an engineer.
