1. POLE AND PEDESTAL MUST BE DESIGNED TD MEET THE REQUIREMENTS OUTLINED IN THE "STANDARD SPECIFICATIONS FDR STRUCTURAL

SUPPORTS FDR HIGHWAY SIGNS LUMINAIRES AND TRAFFIC SIGNALS", PUBLISHED BY M SHTD, FDR A WIND VELOCITY OF 100 MPH.

THE CONTRACTOR SHALL SUBMIT TWO SETS OF WORKING DRAWINGS, SIGNED AND SEALED BY A PROFESSIONAL ENGINEER REGISTERED

IN THE STATE OF COLORADO, IN ACCORDANCE WITH SECTION 105.02 OF THE ST AND ARD SPECIFICATIONS FDR ROAD AND BRIDGE CONSTRUCTION.

DESIGN DATA

THE DESIGNS HEREIN ASSUME THAT FLASHING BEACONS ARE INSTALLED WITHIN

THE ROADWAY PRISM WITH THE FOLLOWING SOIL PARAMETERS:

SOIL DENSITY v = 110 LB./CU.FT.

SOIL COHESION = 750 LB./SQ.FT. FDR MEDIUM STIFF COHESIVE SOIL

SOIL 0 ANGLE = 30 DEG. FDR MEDIUM DENSE CDHESIDNLESS SOIL

SF= 3.0 FDR FLEXURAL RESISTANCE

CONT ACT THE ENGINEER IF THE FLASHING BEACON WILL NOT BE INSTALLED WITHIN

THE ROADWAY PRISM DR IF ANY OF THE FOLLOWING SOIL CONDITIONS ARE ENCOUNTERED DURING DRILLING:

/0 THE SOIL HAS A HIGH ORGANIC CONTENT OR CONSISTS OF

SATURATED SILT AND CLAY.

B) THE SITE WON'T SUPPORT THE WEIGHT OF THE DRILLING RIG.

C) THE FOUNDATION SOILS ARE NOT HDMDGENDUS.

D) FIRM BEDROCK IS ENCOUNTERED.

E) A HIGH GROUNDWATER TABLE IS ENCOUNTERED.

F) LARGE BOULDERS ARE ENCOUNTERED.

FOOTING DESIGN IS BASED ON 100 MPH WIND LOAD ON A 48 IN. X 48 IN. DIAMOND SIGN PANEL MOUNTED 9 FT.ABOVE THE GROUND, WITH A 24 IN. X 24 IN. RECTANGULAR PLAQUE UNDERNEATH AND A FLASHING BEACON 12 IN. ABOVE. IF A SIGN CONFIGURATION IS PROPOSED THAT EXCEEDS

THESE DIMENSIONS, THE FOOTING DESIGN MUST BE ENGINEERED AND SIGNED AND SEALED BY
