Body
Issue/Request:
An Ordinance approving Change Order #2 to the contract with Vance Brothers, Inc. for the Surface Seal 19/20 project, for an increase of $10,208.00 for a revised contract price of $1,107,780.35 and an increase of 10 calendar days to reach substantial and final completion.
Key Issues:
• Microad is a new variation of micro surface designed of heavily-traveled roads
• The new Microad System uses a different aggregate (granite) and polymer/emulsion, than traditional micro surface.
• The Microad System should produce in a longer-lasting surface seal that will stay darker longer
Proposed City Council Motion:
FIRST MOTION: I move for a second reading of an Ordinance approving Change Order #2 to the contract with Vance Brothers, Inc. for the Surface Seal 19/20 project, for an increase of $10,208.00 for a revised contract price of $1,107,780.35 and an increase of 10 calendar days to reach substantial and final completion.
SECOND MOTION: I move adoption of an Ordinance approving Change Order #2 to the contract with Vance Brothers, Inc. for the Surface Seal 19/20 project, for an increase of $10,208.00 for a revised contract price of $1,107,780.35 and an increase of 10 calendar days to reach substantial and final completion.
Background:
The scope of this project included the application of 426,056 square yards of surface seal (micro surface) in 25 areas throughout the City. The Microad System will be utilized on Todd George Parkway between McKee Lane and Tudor Road, which is 5% of project total project. Microad system is an enhanced micro surface process that uses a granite aggregate and modified polymer/emulsion mixture. The combination of aggregate and chemicals is designed to produce a longer lasting seal coat that should reduce the long-term maintenance cost. The granite will be black granite so the seal coat will stay darker longer. The dark aggregate reduces glare and speeds up snow melt.
Additional time is needed to facilitate equipment mobilization and importing aggregate from Farmington, MO. An additional ten (10) days will be added to the contract to account for this additional work.
