STANDARD TEMPORARY SHORING NOTES ON PLANS               1-20-09
(Choices are in parenthesis separated by "or" and stations are 
optional if there is only one shoring location.)

USE A 1.5:1 (H:V) SLOPE OR FLATTER IN LIEU OF TEMPORARY SHORING 
FROM STATION ____________, ________FT (m) __________, TO STATION 
____________, ________FT (m) __________ AS SHOWN ON THE PLANS.

FOR TEMPORARY SHORING, SEE TEMPORARY SHORING PROVISION.

DO NOT USE STANDARD SHORING FROM STATION ____________, ________FT 
(m) __________, TO STATION ____________, ________FT (m) __________.

DO NOT USE STANDARD TEMPORARY SHORING FROM STATION 
____________, ________FT (m) __________, TO STATION ____________, 
________FT (m) __________.

DO NOT USE A TEMPORARY MSE WALL FROM STATION ____________, 
________FT (m) __________, TO STATION ____________, ________FT (m) 
__________.

USE A TEMPORARY MSE WALL FROM STATION ____________, ________FT (m) 
__________, TO STATION ____________, ________FT (m) __________.

TEMPORARY SHORING IS REQUIRED FOR THE PIPE, DROP INLET OR 
UTILITY INSTALLATION FROM STATION ____________, ________FT (m) 
__________, TO STATION ____________, ________FT (m) __________.  SEE 
TEMPORARY SHORING PROVISION.

WHEN USING CONTRACTOR DESIGNED SHORING FROM STATION 
____________, ________FT (m) __________, TO STATION ____________, 
________FT (m) __________, DESIGN SHORING FOR THE FOLLOWING IN-SITU 
ASSUMED SOIL PARAMETERS:
        UNIT WEIGHT OF SOIL ABOVE WATER TABLE, gamma = _____ PCF (kN/m3)
        UNIT WEIGHT OF SOIL BELOW WATER TABLE, gamma = _____ PCF (kN/m3)
        FRICTION ANGLE, phi = _____ DEGREES
        COHESION, c = _____ PSF (kPa)

DRIVEN PILING FOR TEMPORARY SHORING FROM STATION ____________, 
________FT (m) __________, TO STATION ____________, ________FT (m) 
__________ (WILL or MAY) NOT PENETRATE BELOW ELEVATION ________ FT 
(m) DUE TO THE PRESENCE OF AN OBSTRUCTION, VERY DENSE OR HARD 
SOIL, WEATHERED OR HARD ROCK.

IT MAY BE PREFERRED OR NECESSARY TO ANCHOR TEMPORARY SHORING 
FROM STATION ____________, ________FT (m) __________, TO STATION 
____________, ________FT (m) __________.  THE TEMPORARY SHORING 
PROVISION DOES NOT APPLY TO ANCHORED TEMPORARY SHORING.  IF 
ANCHORED SHORING IS PROPOSED, SUBMIT WORKING DRAWINGS, DESIGN 
CALCULATIONS AND AN ANCHORED TEMPORARY SHORING PROVISION 
FOR REVIEW AND ACCEPTANCE IN ACCORDANCE WITH ARTICLE 105-2 OF 
THE STANDARD SPECIFICATIONS.
or
IT MAY BE PREFERRED OR NECESSARY TO ANCHOR TEMPORARY SHORING 
FROM STATION ____________, ________FT (m) __________, TO STATION 
____________, ________FT (m) __________.  (FOR ANCHORED TEMPORARY 
SHORING, SEE ANCHORED TEMPORARY SHORING PROVISION. and/or FOR 
TEMPORARY SOIL NAIL WALLS, SEE TEMPORARY SOIL NAIL WALLS PROVISION.)

FOR CONTRACTOR DESIGNED SHORING, SURVEY THE SHORING LOCATION 
TO DETERMINE EXISTING ELEVATIONS AND ACTUAL DESIGN HEIGHTS 
BEFORE BEGINNING DESIGN.

FOR PORTABLE CONCRETE BARRIERS ABOVE AND BEHIND TEMPORARY 
SHORING, USE AN NCDOT PORTABLE CONCRETE BARRIER (UNANCHORED 
OR ANCHORED) OR AN OREGON TALL F-SHAPE CONCRETE BARRIER IN 
ACCORDANCE WITH THE TRAFFIC CONTROL PLANS.

(NO or LIMITED) SUBSURFACE INFORMATION IS AVAILABLE IN THE VICINITY 
OF THE TEMPORARY SHORING FROM STATION ____________, ________FT (m) 
__________, TO STATION ____________, ________FT (m) __________.  THE 
INFORMATION PROVIDED FOR DESIGN WAS ASSUMED AND MAY NOT BE 
APPLICABLE TO THE ACTUAL SITE CONDITIONS ENCOUNTERED DURING 
CONSTRUCTION.

WHEN BACKFILL FOR A ____________ (RETAINING WALL or REINFORCED 
BRIDGE APPROACH FILL) OVERLAPS WITH THE REINFORCED ZONE OF A 
TEMPORARY MSE WALL, USE EITHER SHORING BACKFILL OR THE 
MATERIAL SPECIFIED FOR THE ____________ (RETAINING WALL or 
REINFORCED BRIDGE APPROACH FILL), WHICHEVER IS BETTER, IN THE 
REINFORCED ZONE.
