Title
Consider a resolution authorizing the Mayor to execute Quantity Adjustment/Change Order No. 5 with Chasco Constructors for the Kenney Fort Boulevard (Arterial A) Project.
Body
The original contract for construction services was approved by the City Council on June 23, 2011 for the amount of $17,095,753.80 to extend Kenney Fort Boulevard from Joe DiMaggio south to Forest Creek Boulevard.
Quantity Adjustment No. 1 added John Harris and Susan Hickox as additional insured and reinforced concrete pipe was replaced with 36" corrugated concrete pipe for culvert the crossing at the request of Union Pacific Railroad at the cost of $10,519.
Quantity Adjustment No. 2 was for quantity adjustments in railroad related work and field related quantity changes at a cost of $34,007.70.
Quantity Adjustment No. 3 was for expected, but unknown railroad costs and street light installation expenses at a cost of $540,949.30. Fourteen days were added to the construction contract. The total cost of the construction contract would be $17,681,229.80.
Change Order No. 4 /Quantity Adjustment was for revisions to the storm sewer system 1A and revisions to the intersection layout at Forest Creek Blvd. It also added joint restraints for the 16-inch waterline bore and the addition of a 24-inch steel casing for a total cost of $114,669.55.
Once the project was substantially complete and open to traffic, the City Manager asked about the lack of planned landscaping to portions of the median. Weeds had grown up rapidly due to seasonal rain, and were an eyesore on a brand new, expensive arterial road. He asked the department to look into optional treatments to the median that would be cost effective and not create new, additional, ongoing maintenance. Change order #5, addresses this issue as well as some final adjustments to the project that were exposed during the development of the punch list items.
The total cost of Change Order No. 5 is $ 77,305.00 with the addition of 28 calendar days to the contract to complete the required work. This change order adds the decomposed granite to the roadway medians, flumes at the MSE walls, and rock filter dams at the outfall channel, revised traffic signalization at Forest Creek Intersection, holding of a utility pole while trenching and the deduct of pavement marking revisions. The total contract price after revisions is $ 17,873,204.35.
Cost: $77,305.00
