1. Question: Where are the seeding specifications? I don’t see them.

Contractor (SEP 2006).” The requirement is 50%.
3. Question: I am a precaster here in Grand Jct. checking to see if the culverts to be replaced will be reinforced concrete pipe and if the proposed 10’ x 10’ Box culvert can be precast?

Plan M601‐1

4. According to final geotechnical investigation repot for Rio Blanco County Road 5&3 intersection.
Page 7 states: “Bedrock cut slopes would likely require heavier equipment, rock splitting and/or blasting. On‐site soils and bedrock could be used in site grading fills. We (Yeh & Associates) recommend the materials be processed to a maximum particle size of 6 inches and less.”
It has been Precision Excavating Inc.’s experience from prior County Road 5 projects that whether ripping or blasting, sizes will average 3’ or more. Are you going to stay with 6” specification or allow a rock fill specification that will greatly reduce cost to project. Additionally will you add items for blasting and rock processing with quantities, to give every contractor an even playing field for bidding and ease of payment for work completed?
a. Blasting and rock processing are subsidiary to embankment construction Items 20420‐ 0000. See Subsection 204.17 of the SCRs.
Subsection 204.10 of the FP‐03 does allow for rock embankment and 204.11 of the FP‐ 03 indicates the process for determining the gradation of a rock embankment and the compaction requirements.
5. Embankment – complete in place has the quantity for reshaping the irrigation ditches also. We feel this should come out and be a separate quantity, as the material may need to be imported to meet the 10 PI?
a. Sheet 18 of the Plans indicates the total amount of material required to meet the PI requirements. The cost of import is subsidiary to the embankment pay item.
6. If site does not generate enough topsoil to cover the 52,864 s.y. should there be an import item quantity to bid?
a. Topsoil quantities are accounted for on sheet 102 of the plans. Remove and conserve the top 4” of material. Place back on finished slopes and condition the soil per section 624 of the SCRs.
7. Work sheet shows 10% shrink and import of approx. 5,000 c.y. What if job actually fluffs due to rock. Should you have a quantity for haul off of excess?
a. A pay item will not be added at this time.
