CRADLES TYPE 1A AND 2A AND ENCASEMENT TYPE 1A SHALL BE 660-B-4000. USE IS LIMITED TO BEDDING CONCRETE
OVER WHICH BACKFILL WILL BE PLACED NOT LESS THAN 40 HOURS AFTER PLACEMENT. FOR BACKFILL AFTER 24 HOURS,
ADD A NON-CHLORIDE ACCELERATING ADMIXTURE APPROVED BY THE ENGINEER AT DOSEAGES AS REQUIRED BY THE
MANUFACTURER OF THE ADMIXTURE. FOR BACKFILL AFTER 16 HOURS AND REMOVAL OF SHEETING AFTER 18 HOURS,
USE 660-C-4000 WITH A NON-CHLORIDE ACCELERATING ADMIXTURE APPROVED BY THE ENGINEER AT DOSAGES AS
REQUIRED BY THE MANUFACTURER OF THE ADMIXTURE.
2. THE CONCRETE FOR CRADLES TYPE 1 AND 2 AND ENCASEMENT TYPE 1 SHALL NOT BE POURED AGAINST TRENCH
SHEETING, FORMS, OR ON LOOSE MATERIAL IN THE TRENCH BOTTOM, BUT SHALL BE POURED AGAINST AND ON THE
UNDISTURBED TRENCH WALLS AND BOTTOM.
3. THE CONCRETE FOR CRADLES TYPE 1A AND 2A AND ENCASEMENT TYPE 1A MAY BE POURED AGAINST TRENCH SHEETING,
FORMS, OR AGAINST THE TRENCH WALLS, BUT SHALL NOT BE POURED ON LOOSE MATERIAL IN THE TRENCH BOTTOM.
4. UNLESS OTHERWISE PROVIDED IN THE SPECIFICATIONS OR AUTHORIZED BY THE ENGINEER, WHEN THE MAXIMUM
ALLOWABLE TRENCH WIDTH HAS BEEN EXCEEDED.
THE PIPE SHALL BE CRADLED WITH TYPE 1 OR TYPE 2 IF THE
TRENCH IS IN UNDISTURBED SOIL OR TYPE 1A OR TYPE 2A IF THE TRENCH IS IN UNSTABLE SOIL. IF THE TRENCH
WIDTH IS LESS THAN ONE AND ONE HALF TIMES THE MAXIMUM ALLOWED BY THE SPECIFICATIONS WITHOUT SPECIAL
BEDDING, OR IF THE COVER ON THE PIPE IS LESS THAN TEN FEET. CRADLE TYPE 1 OR 1A SHALL BE USED. IF THE
TRENCH WIDTH IS MORE THAN ONE AND ONE HALF TIMES THE MAXIMUM ALLOWED BY THE SPECIFICATIONS WITHOUT
SPECIAL BEDDING AND THE COVER IS TEN FEET OR MORE, CRADLE TYPE 2 OR 2A SHALL BE USED.
5. UNLESS OTHERWISE AUTHORIZED BY THE ENGINEER, ALL CRADLES AND ENCASEMENTS SHALL BE PLACED SUCH THAT

PRIOR TO THE REMOVAL OF THE FRAME OF ANY MANHOLE, THE CHANNEL OF THE MANHOLE SHALL
BE COMPLETELY COVERED WITH PLANKING OR OTHER SUITABLE MATERIAL SO AS TO PREVENT DEBRIS
FROM ENTERING THE CHANNEL. AFTER THE MANHOLE RECONSTRUCTION HAS BEEN COMPLETED ALL
DEBRIS SHALL BE REMOVED FROM WITHIN THE MANHOLE AND THE COVER OVER THE CHANNEL SHALL
BE REMOVED.
2.
WHEN THE MANHOLE IS TO BE RECONSTRUCTED TO A STRAIGHT SIDED MANHOLE, THE BRICK WORK
SHALL BE REMOVED TO THE HIGHEST POINT OF THE VERTICAL WALL. THE SLOPE OF THE CORBELED
SIDE SHALL NOT EXCEED 2 INCHES IN 5 INCHES. THE MANHOLE STEPS SHALL BE PLACED ON THE
VERTICAL SIDE. SEE CASE III.
3.
WHEN THE MANHOLE IS TO BE RAISED AN AMOUNT SUCH THAT DIMENSION "A" (CASE II) IS LESS THAN
4’, THE BRICKWORK SHALL BE REMOVED TO A POINT WHERE THE INSIDE DIAMETER IS A MINIMUM OF
30 INCHES. THE MANHOLE WALL SHALL THEN BE CONSTRUCTED VERTICALLY TO A POINT 15 INCHES
BELOW THE TOP OF THE MANHOLE. SEE CASE II.
4.
WHERE THE MANHOLE IS TO BE RAISED SUCH THAT DIMENSION "A" (CASE II) WOULD EXCEED 4’, THE
BRICKWORK SHALL BE REMOVED TO THE HIGHEST POINT OF THE VERTICAL WALL AND THE MANHOLE
RECONSTRUCTED PER S-a-201 OR S-a-204.
5.
WHEN THE DEPTH OF THE MANHOLE TO BE LOWERED IS SUCH THAT THE MAXIMUM ALLOWABLE
SLOPES FOR THE BRICKWORK SHOWN FOR CASE I WOULD BE EXCEEDED. THE MANHOLE SHALL BE
RECONSTRUCTED AS
6.
A TYPE "C" MANHOLE PER S-a-203.
MANHOLE STEPS, PER S-a-209, SHALL BE PLACED UNIFORMLY SO AS NOT TO BE MORE THAN 16 INCHES
APART WITH THE TOP STEP BEING 16 INCHES BELOW THE MANHOLE FRAME.
