Question
Answer
Item 619.1 — Maintenance of Traffic — As this is an arterial contract |
assume we will have to create the MOT plans as we did last year. Is
there any kind of timeline for the approval process? For example is
there a minimum amount of time they need to be in before the street
can be worked on and is there a max allowable time for the contractor
to receive an approval from the city’s traffic engineer?
Traffic Control Plans as outlined in Supplementary Conditions Section
15 Traffic Control Plan shall be submitted with the Contractor's
proposal to close a road in accordance with General Conditions
Section 17.07 a minimum of five days prior to the proposed partial or
full closure. This will allow time for review of the submittal. However,
a timeline cannot be committed to in advance for approval because
approval is dependent on the completeness and appropriateness of
the submitted information.
Item 618.7 — Flaggers — It was mentioned in the pre-bid that there is
the possibility that some of the streets slated for days may move to
nights based on traffic counts and discussions further down the
road. Will the contractor be compensated under the flagger item for
any additional night streets beyond the 3 anticipated? Would there be
any opportunity for a change order on the other items in the contract
if they were to be performed at night?
If additional streets not outlined in the Supplement Conditions Section
9 Work Hours need to be move to nights, a change order for the shift
differential of flagging personal will be executed. All other items
completed at night will be at no additional cost to the Owner.
Item 618.6 — Uniformed Police — There was an issue with getting police
to service these arterial streets last year. Is the city going to try to
help secure police for this contract? If not is the plan to just use
additional flaggers where details cannot be filled?
The City cannot facilitate that Uniformed Officers show up/fill a
requested detail. The contractor shall submit a contingency in the TCP
for the use of additional flagging personal if the use of Uniformed
Officers cannot be secured.
General note on 0.5% TRB — The plants would need to run at the 0.5
TRB for the whole day when used. The HMA would incur additional
costs due to this.
Comment noted.
3 Week requirement for open streets — would be possible to treat the
milling/paving separate from the sidewalks/curbing/ADA requirements
as far as the allowable ‘open’ streets?
The time requirements are to ensure a contractor is continually
working on open streets and the disruption to the public is minimized
as much as possible. All sidewalk/ramp work on available streets
needs to be completed by the end of the 3rd week in July. It is
acceptable to commence work on sidewalk ramps in advance of
milling/reclamation.
Item 608.24/608.36 — Concrete Sidewalks — Will the city be requiring
fibers in the concrete for the sidewalk items? The spec references
NHDOT spec which does not require them.
Synthetic fiber reinforcement will be required in item 608.24 4"
Concrete Sidewalk. Synthetic fiber reinforcement shall be microfibers
at a dosage rate of 1.5 lbs. per cubic yard of concrete. Synthetic fiber
reinforcement will be acceptable, but not required, in Item 608.36 6"
Reinforced Concrete Sidewalk where wire mesh reinforcement is to be
included.
