1. THIS STRUCTURE MAY BE USED WHEN THE DEPTH OF COVER IS NO GREATER THAN
THE DESIGN COVER OF EXISTING RCB. IF THIS DEPTH IS EXCEEDED. OR PROPOSED
MANHOLE SHAFT EXCEEDS 900 mm (36*) IN DIAMETER A DETAILED PLAN WITH
CALCULATIONS PREPARED BY A CIVIL OR STRUCTURAL ENGINEER REGISTERED IN THE
STATE OF CALIFORNIA SHOWING THE PROPOSED MANHOLE SHALL BE SUBMITTED TO
THE AGENCY FOR APPROVAL.
2. STRUCTURAL NOTES.
A DIMENSIONS FROM FACE OF CONCRETE TO REINFORCING STEEL ARE TO
CENTER OF BAR UNLESS OTHERWISE SHOWN.
B. CONCRETE DIMENSIONS SHALL BE MEASURED HORIZONTALLY OR VERTICALLY
ON THE PROFILE. AND PARALLEL TO OR AT RIGHT ANGLES (OR RADIALLY)
TO CENTER LINE OF CONDUIT ON THE PLAN EXCEPT AS OTHERWISE SHOWN.
C. ALL BAR BENOS AND HOOKS SHALL CONFORM TO THE AMERICAN CONCRETE
INSTITUTE'S -BUILDING COOE REQUIREMENTS FOR REINFORCED CONCRETE.
LATEST EDITION.
D. PLACING OF REINFORCEMENT SHALL CONFORM TO THE AMERICAN CONCRETE
INSTITUTE'S 'BUILDING CODE REOUIREMENTS FOR REINFORCED CONCRETE'.
LATEST EDITION.
E. TRANSVERSE REINFORCING STEEL SHALL TERMINATE 40 mm (I 1/2") FROM THE
CONCRETE SURFACES UNLESS OTHERWISE SHOWN.
F. NO SPLICES IN TRANSVERSE STEEL REINFORCEMENT SHALL BE PERMITTED
OTHER THAN SHOWN ON THE PROJECT DRAWINGS.
6. ALL STRUCTURAL CONCRETE SHALL BE PORTLAND CEMENT CONCRETE WITH
A 28 DAY COMPRESSIVE STRENGTH OF 28 MPo (4000 PSI).
H. ALL REINFORCING STEEL SHALL CONFORM TO ASTM A 6I5M. GRADE 300
(ASTM A 615. GRAOE 40).
3. WHERE REINFORCEMENT IS REQUIRED TO EXTEND THROUGH THE NEW JOINT
CONCRETE SHALL BE REMOVED IN THE FOLLOWING SEQUENCE.
A. A SAW CUT SHALL BE MADE 40 mm (I 1/2') DEEP AT THE REMOVAL LIMITS.
CARE SHALL SE EXERCISED IN SAWING AT THE REMOVAL LIMITS SO AS NOT
TO CUT THE REINFORCING STEEL WHICH SHALL BE RETAINED AND EXTENDED
INTO THE NEW CONSTRUCTION AS INDICATED ON THE PROJECT DRAWINGS.
B. USING HAND HELD EQUIPMENT THE CONCRETE SHALL BE CAREFULLY REMOVED
FOR THE FULL DEPTH OF THE WALL OR SLAB AND FOR A MINIMUM DISTANCE
FROM THE SAW CUT EOUAL TO THE LONGEST EXTENSION OF THE EXISTING
BARS TO BE EXTENDED INTO THE NEW CONSTRUCTION. THIS EXTENSION
SHALL BE 30 BAR DIAMETERS UNLESS OTHERWISE SHOWN.
C. EXISTING REINFORCEMENT SHALL BE CUT TO THE REQUIRED BAR EXTENSION.
D. THE REMAINING CONCRETE MAY BE REMOVED BY ANY SUITABLE METHOD
UPON APPROVAL OF THE ENGINEER. WHO SHALL BE THE SOLE JUDGE OF THE
USE OF ANY CONCRETE REMOVAL EQUIPMENT. EXPLOSIVES. WRECKING BALL
OR OTHER SIMILAR DEVICES WHICH ARE LIKELY TO DAMAGE THE CONCRETE
TO BE LEFT IN PLACE SHALL NOT BE USED.
E. INTERNAL SUPPORT OF THE EXISTING RCB SHALL BE PROVIDED DURING THE
REMOVAL AND RECONSTRUCTION OF THE TOP SLAB. A DETAILED PLAN WITH
CALCULATIONS PREPARED BY A CIVIL OR STRUCTURAL ENGINEER REGISTERED
IN THE STATE. OF CALIFORNIA SHOWING THE TEMPORARY SUPPORT SYSTEM
SHALL BE SUBMITTED AND APPROVED BY THE AGENCY PRIOR TO THE START
OF REMOVAL WORK.

GENERAL NOTES:
Designotion: Standord single or multiple box culverts are ahown on
plans as span times height with maximum cover over
roof thus! 8'x 5'RCB with 10'or
DBL 10'X 5'RCB with 20', followed by
alternatives.
Alternatives!
Single cellt Invert will be sloped unless "trapezoidal
invert", "flat Invert" or "V Invert" Is included in
designation.
Multiple cell! Invert will be vee unless "flat Invert"
specified. Ends of culvert will b« rounded untess
"square ends" ore designoted. Parapets will be as
shown unless designated In plons. Such designations may be different for Inlet and outlet ends. Quantities!
Quantities are for the sloped or vee invert and
do not include "d" bors, nor splices in longitudinal
bars, nor temperature reinforcement for exposed
roof, nor concrete or reinforcement for parapets,
cutoff walls or paving notches.
Reinforcement plocement: Main reinforcement is to be placed transverse or, for curved culverts, radial. When radial, reinforcing spacing of the "a", f" and "g" bars Is measured along the centeriine. Stagger splices not shown. Hooi^s may be rotated or tilted, os necessary, for clearance.
Special reinforcement coverage: Box standard plans are not to be used for culverts in 0 corrosive environment or where there is a severe abrasive flow condition or In freeze-thaw locations.
Special design: Required for culverts with conditions, loads, design bearing pressures or sizes greater than those given on this plan or Standard Plans D80 & 081. Also required for multiple cell culverts with unequol spans. For culverts with railroad loading, see the current AREA design specification.
3 or more eel Is:
For culverts with more than two cells, use dimensions
and reinforcement for the standard "double box
culvert" and adjust quantities accordingly.

GENERAL NOTES
QUANTITIES; Quontltles ore for the sloped invert slob and do
not include splices in the longitudinal bars, nor temperature
reinforcement for exposed top culvert, nor concrete or
reinforcement for porapets or cutoff wolls
SPECIAL COVERAGE: Box standard plans ore not to be used for
culverts in a corrosive environment or where there is a severe
abrasive flow condition
DESIGNATION: Show on plans as span x height-strength
classification x length, thus 1.22m x 1.22m-A x 18.3m (4 x
4-A x 60'), followed hiy alternatives.
ALTERNATIVES: Invert will be sloped unless "Tropezoidal Invert",
"Flat Invert" or "V Invert" is included in designation. Ends of
culvert will be rounded unless "Square Ends" ore designated.
Parapets will be as shown unless " ft. parapet" is
designated in plans. Such designations may be different for
inlet and outlet ends.
REINF. PLACEMENT: Main Reinforcement is positioned transverse
or, for curved culverts, radial when rodiol, reinforcing spacing
is measured along C
CONSTRUCTION NOTES
CONCRETE: Bottom slab & wolls shall be class 332 kg/M^
-B-22Mpa (560-B-3250). Top slab shall be class 332 kg/M^
-C-22Mpa (560-C-3250),
EXPANSION JOINTS: Bottom Slob-No expansion joints shall be
ploced.
Top Slob and Wolls-When cover is less than span length, place
13mm (l/2") expansion joint filler at 15.2m (50')± centers
outside the paved roadway lanes and place bridge detoil 3-2

DESIGN NOTES
SPECIFICATIONS
DESIGN: AASHO, dated 1973, with revisions as supplemented by
Stote of Coiifornio Bridge Planning and Oesign Monual.
Sections designed for culvert in a trench on hard foundotion, or
culvert untrenched on yielding foundation, for culverts on piles or
rock foundotlons, special design will be required.
LOADING
LIVE LOAD: For legol highway loads, use HS20-44 or Alternative
with 30% impoct for all cover depths, no impact on invert.
COVER LESS THAN 610mm (2') - Wheel load distribution on the
top slob is E=0.175S+3.2' longitudinally and concentroted along
the span. Wheel load distribution on the invert slab is 2.29m
(7.5')longitudlnally and uniformly over the breath of the culvert.
COVER 610mm (2') OR MORE - Wheel loads distributed uniformly
over a square, the sides of which ore 1.75 times the depth of
cover, but not less longitudlnolly than E on the top slab, or 2.29m
(7,5') on the invert slob when such oreos from several wheel
concentrations overlap, the total load shall be considered as
uniformly distributed over the oreo defined by the outside limits of
the individual areas, but the overall longitudinal dimension shall not
exceed the total length of the supporting slob. Neglect live load,
on single spans when cover is more than 2.44m (8') and exceeds
span, and on multiple spans when cover exceeds distance between
exterior walls.
DEAD LOAD: Earth load of 120 pcf and on equivolent fluid pressure
of 36 pcf, reduced to 84 pcf and 25 pcf respectively for clear
spans of 20' or less.
UNIT STRESSES: Fs = 138Mpa (20,000 psi), N = 10
Fc = 8.27Mpa (1,200 psl)
Reinforcement embedment is 38mm (1-1/2) dia. cleor, min
25.4mm (l") ond in 6.35mm (l/4") increments, except as noted.

"Strength Classification, symbolized by the letters "A", "B", "C" etc.,
ot the top of the data table is merely a convenient designation for
0 particular structuroi section for a culvert of any given opening it
is dictated by the cover or depth of fill over the the top slob.
