RE.Reopen~ng~of Freeport Pkwy
Steve, due to the wet and frigid weather conditions, it will be
impossible to complete the construction of Freeport Pkwy. and reopen
it to traffic by 2/15/89 for the following reasons in accordance with
COG specifications.
1) Subbase cannot be frozen
2) Subbase mositure cannot be over 6% optimum, it is 12+
3) Subgrades will have to dry out to make final grade & compaction
4) Concrete cannot be poured when temperature is 40° and falling
5) Air temperature must be 35° and raising
6) Air surrounding concrete must retain 50° for 5 days
7) Curing time shall be a minimum of 7 days from last pour prior
to traffic being allowed on it
8) Traffic buttons and paint striping cannot be applied on until
temperature is 40° plus and dry
I am monitoring the weather and site conditions very closely. It
looks llke we will get a weather break in temperature this weekend
(10th, llth), but it is predicted to rain or snow (9th llth).
If we do indeed get the weather break, they should be able to dry,
compact, and make grade on the week of the 13th, form & pour on the
week of the 20th, cover & cure on the week of the 27th and reopen
Freeport Pkwy. sometime in the week of March 6th.
Please bear-in-mind that any r~in the occurs after the 13th affects
this schedule, two days to every one rain day and any precipitation
that freezes affects the schedule 3 days to 1, due to penetration,
of moisture as'it thaws.
I will
will also noti~ the Cable
to proceed.
