Change Order No. 2 on the Ohio Street Pavement Improvements, Project No. 99-1189.
BACKGROUND
The City Commission approved a contract with Shears Construction, L.P. on August 23, 1999 for
asphalt pavement improvements on two miles of Ohio Street from Belmont Boulevard on the south
to Greeley Avenue on the north. The project involves 1 ½ inches of asphalt milling and overlay with
extensive crack sealing throughout the project. The intersection of Ohio and Crawford was excluded
from the project at that time to allow additional time for evaluation of that intersection. The project
is approximately seventy five percent complete and considerably ahead of schedule at this time.
On May 10, 1999, the City Commission authorized an engineering contract with Bucher, Willis &
Ratliff Corporation to analyze pavement repair options and traffic system improvements at the
intersection of Ohio Street and Crawford Street. Regarding the pavement repair options, BWR
considered short-term issues such as capital costs, traffic disruption, access to adjacent properties
and others. They also took into account long-term issues including life expectancy of the pavement,
maintenance costs and future rehabilitation. The pavement options considered were full-depth
concrete, full depth asphalt, asphalt overlay and ultra-thin whitetopping. "Ultra-thin whitetopping"
is a process in which 3-inch concrete pavement is placed over the existing asphalt pavement in a very
short period of time. The final recommendation from BWR is to proceed with an asphalt
overlay of the intersection as the most cost-effective and practical method at this time. This
is certainly not a condemnation of ultra-thin whitetopping. That process will be tried in Salina,
however this intersection was not the appropriate candidate at this time.
Regarding traffic system improvements at the intersection, a thorough analysis was also conducted
by BWR and city staff. The congestion and accident experience at this intersection continues to
increase as a function of additional growth in traffic on these two major street corridors. The
intersection of these two four-lane arterial streets handle in excess of 41,000 entering vehicles daily.
The heavy traffic volumes during the evening commuter peak hour(4:30-5:30 p.m.) currently operate
at a level of service "F" on a letter grade scale of A through F. BWR indicates that the construction
of double left turn lanes on all legs of the intersection would improve the level of service to "D",
however additional lanes are beyond the scope of the current project. An alternative is to eliminate
part of the raised curb for the current left turn lane, replacing it with a painted median. That will
provide additional room for left-turning vehicles which reduces congestion in the through lanes.

asphalt milling and overlay of the intersection o£ Ohio and Crawford as well as the partial removal
of the raised median. The City Street Division will assist in the removal of the median. If approved,
the asphalt overlay process at the intersection will begin immediately following completion of the
remainder of improvements on Ohio Street, presumably in early to mid November, 1999. The
project will be completed in less than ten days. The intersection will remain open to traffic
throughout the project.
The 1999 budget allocates $1.3 million in gas tax funds for the street repair program. The original
contract amount of $442,995.40 for this project was paid from that account. Change Order No. 1
on the project, approved by the City Commission on October 18, 1999, increased the contract by
$39,300 for additional pavement crack sealing. This Change Order No. 2, if approved, will increase
the contract by $85,697.60 or 17.8 percent to a total of $567,993.00.
ACTION
It is recommended that the City Commission approve Change Order No. 2 on the Ohio Street
Pavement Improvements, Project No. 99-1189, in the amount of $85,697.60.
