Text of Legislative File CM -2020-033
This Supplemental Agreement is for professional consulting services related to construction
material testing for the Red Bud Right Tum Lane project. The professional services were to
include nuclear density testing, soil sampling and testing, and concrete and asphalt testing. This
Supplemental Agreement is to provide an additional $1,762.15 for a grand total of $9,031.80.
During the early phases of construction, our (CORR) team concluded that it was in the city's
best interest to provide a full asphalt overlay of Red Bud Ln from 79 to Mickey Mantle
PI/Pioneer Crossing Dr to provide pavement preservation in extending the life of the existing
structure. This addition, along with the existing right turn lane expansions, moved us to require a
supplemental agreement for material testing. Although we were able to save a in testing other
materials, testing increased for the asphalt hot mix in order to incorporate the shift in volume of
material we were then going to use. Those additional tests resulted in the difference of
$1,762.15 necessary for the new total.
Cost: $1,762.15
