City Engineer Gus Psihoyos is recommending acceptance of the construction contract
for the Locust Street Asphalt Resurfacing Project (9 Street to 17 Street), as
completed by Tschiggfrie Excavating Co., in the final contract amount of $643,936.18,
which is a 19.2% increase from the original contract amount of $540,420.12. There was
an increase in the contract value because of unforeseen items encountered during
construction which are briefly summarized as follows:
• Three existing brick sanitary manholes were reconstructed due to their
deteriorated condition which required additional excavation because of the extra
depth of the structures. This additional work was at a cost of $7,500.
• An additional three storm sewer intake structures were reconstructed due to their
deteriorated condition. This additional work was at a cost of $7,000.
• The quantity of sidewalk along Locust was increased due to the installation of
access curb ramps and the additional sidewalk work required to comply with
current ADA standards. This additional work was at a cost of $14,400.
• Based on the observed condition of the existing asphalt pavement after the
milling operation, it was determined that additional surface patch work would be
required at the deteriorated transverse joints. Before the transverse joints could
be patched the contractor was required to clean and prep the joints before
paving. This additional work was at a cost of $21,900.
• During the project the contractor encountered a sink hole at the intersection of
11 & Locust that was caused by an existing old limestone arch storm sewer
structure that had failed. The contractor needed to make extensive repairs to the
old limestone arch storm sewer structure. This additional work was at a cost of
$37,950.
I concur with the recommendation and respectfully request Mayor and City Council
approval.
