Authorization To Execute Amendment To Contract With Alliant Engineering, Inc., For County Road 86 Railroad Bridge Inspection, Material Testing, And Track Monitoring Services In Castle Rock Township, County Project 86-34
end
PURPOSE/ACTION REQUESTED
Authorize execution of an amendment to the contract with Alliant Engineering, Inc., for inspection, material testing, and track monitoring for the construction of the railroad bridge over County State Aid Highway (CSAH) 86.
SUMMARY
To promote a safe and efficient transportation system throughout the County, Dakota County is replacing the original timber railroad bridge over CSAH 86 as part of the roadway reconstruction project (County Project 86-34) as shown on the attached Location Map.
Alliant Engineering, Inc., has been contracted to inspect the construction and track monitoring of the railroad bridge. The railroad requires the tracks to be monitored for deflection three times a day, seven days a week, while the bridge is being constructed. The construction of the bridge has taken longer than anticipated, which increases the hours of construction inspection and the days of track monitoring.
The current contract amount is $599,910, and the bridge completion date is currently spring 2025. The inspection, material testing, and track monitoring are required until the construction is completed, and the trains are switched over to the new bridge. Track cutover is not allowed until the ground is thawed so that the track monitoring will continue. Costs are now nearing the original contract amount and will soon exceed it.
The requested $254,000 will extend the testing contract through spring, when the project is expected to be completed. The attached Revised Scope and Fee Proposal outlines the changes.
