EXHIBIT 1 – QUESTIONS & ANSWERS
1. You have 3/8” Chips listed but the spec is Grading 67 Stone which would be called 3/4 ” not
3/8”. Shall I bid the spec?
CDOT #67 was incorrectly specified for the 3/8" chips. Contractor shall provide a
bid for well-graded 3/8" aggregate "pea-gravel" or "Squeegee Sand" for pipe
bedding. Contractor shall provide aggregate gradation of percentage passing
designated sieves with their bid.
2. On the 1” Washed Rock you have a CDOT #5 Granular bedding listed as the spec. I cannot
find anything in the CDOT spec that is called #5 granular bedding. We call ours 1” Pipe
Bedding. It also makes the gradation for No. 57 Stone and Class A Filter. (CDOT Section
703 Page 688 and 694 of the Green Book).
The 1" washed rock was incorrectly specified as CDOT #5 Granular Bedding.
Contractor shall provide a bid for uniformly graded and washed material
conforming to CDOT #57 granular bedding.
1-1/2" (37.5 MM) - 100% passing
1" (25 mm) - 95 - 100% passing
1/2" (12.5 mm) - 25 - 60% passing
#4 (4.75 mm) - 0 -10% passing
#8 (2.36 mm) 0 - 5% passing
If contractor cannot meet this specification then an approved equal may be
accepted and the contractor will need to provide aggregate gradation of
percentage passing designated sieves and nominal size designation that best
meets this specification.
