Due to unforeseen subbase conditions, the quantities within the original scope of work have increased for this project. Estimations conducted by visual surface inspection were unable to determine the extent of damage to several areas. A change order increase of $231,345.47 is necessary to complete the remainder of this project, which now includes two (2) additional unexpected full-depth total street overhauls, before weather delays completion until spring.  

As part of the pavement maintenance program, the 2021 Full and Partial Depth Asphalt Patching project originally consisted of 3,914 square yards of full depth pavement repair and 17,515 square yards of partial depth pavement repair.  Staff evaluated all city streets with a pavement condition index below 30.  These targeted repairs to the existing pavement are addressing necessary structural restoration for isolated areas, leaving the remaining structurally sound pavement intact.

During the final construction phase of this project, several areas were revealed to have significant subsurface damage caused by nearby water sources and two of these streets now require a full-depth overhaul. A visual inspection alone is unable to determine this kind of damage.

Superior Bowen was awarded the initial bid for this project as lowest bidder for $664,330.00. They have completed various asphalt projects successfully and timely for the City in the past.

The fiscal impact to the City is $231,345.47. Funding for the 2021 Full Depth and Partial Depth Asphalt Patching project is included as part of the 2020 Pavement Management Construction program in the 2021 adopted budget, page number 90, account number 7011 5406.
