REF: Median paving, Freeport Parkway
Bid ltem I-2 of our Freeport Parkway Reconstruct Project sets up 250 SY of median
paving ~$42.00/SY for a total of $10,500.00. The scheduled repairs are shown at four
locations (M-1 through M-4) and indicate replacement of 4' thick concrete that is
severely damaged at those four locations. The actual field measurement of the damaged
median totals 157 SY for a cost of $6,594.00. Please note that the repair M-4 has been
eliminated since a left turn lane is being built at this location at the expense of the Koll
Center Project now under construction. However, I have added a location at the Gateway
crossover that is also in serious need of replacement.
Median Pavine damaeed areas:
M-1 59 SY ;, 0
M-2 53 SY ~,D
M-3 15 SY a 2.
Gateway 30 SY
157 SY
Because of the inevitability of future damage due to the heavy truck ~xaffic at the
intersections and crossovers, I recommend the installation of a monolithic median nose at
the M-3 instead of the median pavement as scheduled. This will be easier on the tragic
and stru~urally more maintainable since the median area would be poured monolithic

with the curb and the concrete thickness would graduate fi.om 11" to 14" thick instead or'
the 4" cap. The recommended procedure 'to install the mono median nose is as follows:
1. Sawcut and remove existing curb and gutter and median paving.
2, Excavate 6" below subgrade and install 6" of C.T.B. or lime stabilization.
3. Pour reinforced concrete median noso to replace $' pavement and 6" curb.
The tbllowing prices are submitted lbr your considerat/on as a unit price to repa/r and
remove each median nose:
A. lull-width median nose (~-/-14') $2,200.00
B. Turn lane median nose (+/-4') 900.00
A detail of the mm lane median nose as approved for the Koll Center Project is attached.
The full-width nose would be along the same design only wider. Median nose work
would have to be done after all north and southbound lane repairs have been completed
and open to traffic. Local barricading would be required to move traffic toward the
outside lanes since portions of both inside lanes would be removed,
In addition to the replacement at the M-3 location, I recommend that the crossovers at
Gateway and Fritz as well as the turn lane at Ah'line be considered for replacement at th/s
time.
