Subject:
Authorize the Director of Development Services to execute Contract Change Order Number one
with Nikola Construction Corporation for Sewer improvements in Industrial Parkway,
Tippecanoe Avenue, and "I" Street and Pavement Rehabilitation on Sterling Avenue (SW05-05,
SW05-06, SW04-36, & SS06-56), per Project Plan No. 11923A.
Background:
On August 18, 2008, the Mayor and Common Council approved a Resolution to award a contract
to Nikola Corporation for Sewer and Pavement Rehabilitation (SW05-05, SW05-06, SW04-36,
& SS06-56), per Project Plan No. 11923A.
Change Order:
During construction of the sewer and pavement improvements the contractor encountered several
unforeseen conditions and unknown utilities as follows:
I. On "I" Street, the contractor encountered an unmarked abandoned 12" water main that was in
conflict with the proposed sewer. This water main was not identified on the plans and was
located when the trench was excavated. It was necessary to cut and cap the water mainline
without damaging the existing sewer mainline, The removal of the concrete encasement and.
to cut and plug the water main resulted in a cost of$II,640.83.
2. On "I" Street initial boring indicated that the existing asphalt was 6" thick, but there were
locations where asphalt was 10" thick. The contractor was directed to remove and dispose of
the additional 4" of asphalt at a cost of $2,586.84.
3. During construction on Tippecanoe Avenue it was determined that the proposed sewer
mainline would need to be lowered an additional 4.5 feet due to a discrepancy in the design
survey. In order to lower the sewer mainline the contractor was required to dig a deeper
trench, add additional shoring, purchase larger manholes and slurry existing utilities for
protection. The additional construction cost was based on time and materials resulting in an
additional $62,761.08.
4. During pavement rehabilitation on Sterling Avenue it was determined that an additional
1.824 square feet needed to be paved in order to create a smooth transition from the new
asphalt to the existing asphalt. This was done at a cost of $21 ,888.00.
,-,,--
5. The existing crosswalk at Sterling Avenue and Highland Avenue needed to be replaced in
order to meet current ADA standards. The contractor was directed to replace the crosswalk at
a cost of $1 ,897.50.
