EXHIBIT 2 – QUESTIONS & ANSWERS
1. Is there a 5% Colorado in-state preference for this project?
No, there is not an in-state preference.
2. Will there be an asphalt price adjustment for this project?
After carefully consideration, the City has decided not to have the asphalt price
adjustment provision for this project. This change is reflected in the attached
Revised Bid Schedule (Exhibit 1). Please use Exhibit 1 or the attached Excel file
“8165 Add 1 Bid Schedule” in lieu of the previous version.
3. Can the waterline be joint restrained only through the lowering and not require the concrete
thrust blocks?
The waterline plan states that all joints shall be restrained for the entire length
(Sta. 10+00 to 11+15.50). Concrete thrust blocks are not required in the lowering
since all joints will be restrained. All fittings and restraints shall be epoxy coated
with stainless steel bolts.
4. Are bell restraints required on the pipe inside of the steel casing?
Yes, the pipe needs to be restrained inside of the steel casing.
5. Is any cathodic protection required on the waterline pipe?
No, the waterline pipe will not require cathodic protection. However, the Steel
casing will need to be protected per our standards and specifications with anode
bags.
6. Will any customers be affected with a shutdown for the tie-in?
There are no customer services between the two points of connection. During a
shutdown to properly cut and plug, block and/or restrain at the tie-in points there
is a possibility of affecting 18 customer services. An 8 hour shutdown is allowed
for these customers twice during the duration of the project with 48 hours notice.
7. The notes require tracer wire and a locator station, where will the locator station be located?
There is existing tracer wire in the 8” Gate valve on the east side of the ditch. This
needs to be spliced and laid with the proposed pipe to the 8”x4” tie-in on the west
side of the ditch. The tracer wire should be terminated with a locate station
behind the sidewalk at this location.
8. Is there required lengths the existing pipe needs to be restrained back from the proposed
tie-in points on the existing 4” main and existing 8” gate valve?
The restrainment tie back length for the 8” and 4” existing waterlines is 60’ and 30’
respectively. For the purpose of the bid it should be assumed that the 4”
waterline can be cut, plugged and blocked and the 8” waterline can have 60’ of
pipe laid west of it and backfilled during an 8 hour shutdown. A second shutdown
will be required to tie the mains in after it has been tested, chlorinated and blown
off.
