The work necessary for the completion of this contract consisted of removing existing concrete
streets, sidewalks, curb and gutter, curb access ramps, alley approaches and driveways;
constructing street pavement, sidewalks, curb and gutter, curb access ramps, alley
approaches and driveways; adjusting utilities to grade; removing and installing new trees;
reconstructing catch basins; and incidental items of work as required by the contract.
As part of the award, a $112,000.00 contingency allowance was established to address
unknown cost and possibly take advantage of the low contract unit bid price to address
additional concrete repairs and or street rehabilitation in other parts of the City that were not
originally believed to be afforded. Under this contract, contingency funds were used to
rehabilitate Hardin Street and the southern portion of Cypress Street, construct an eastbound
left turn lane at 15t Street, and an alley approach on Newport Island.
