Report on project and motion approving change orders for All Seasons Arena.

Motion approving change orders.

Staff is recommending approval of the following change orders. The All Seasons Arena Board approved this at their March 21^st meeting.
 
Met-Con, Trade Package 1A
Change Order #11, $13,756.13
CO #11 includes the following:

• Additional steel framing and support wall under the existing mezzanine in the North Rink.
• Replacement door hardware for the North Rink Zamboni room door; existing hardware is not able to be reused.

 
Rink Tec, Trade Package 13A
Change Order #6, $10,500.00
CO #6 includes the following:

• The original schedule anticipated the existing dehumidification unit to be shut down for a period of less than 5 days. With the additional work required for the new wall and mezzanine, a change in sequencing is required, which will result in a longer period of inoperability. With the variability of temperatures during spring, staff recommends a temporary unit be brought in for the duration of the shut-down to maintain ice quality. This will cover a one-month rental of a temporary unit.

Malterer Mechanical, Trade Package 23B
Change Order #7, $2,255.00
CO #7 includes the following:

• The new west entrance vestibule was originally designed without supplemental heat due to the proximity of the existing vestibule heater and the supplemental heat generated from the ice plant. After several cold days this year, it was determined that additional heat would be needed to ensure the space functions effectively over its life expectancy.

 
Laketown Electric, Trade Package 26A
Change Order #7, $4,863.57
CO #7 includes the following:

• Wiring of the new cabinet unit heater in the west entrance vestibule
• Electrical connection for the temporary dehumidification unit

 
The above change orders total an increase of $31,374.70. If approved, the contingency will be decreased to $236,132.42.
 
Staff recommends a motion approving the change orders.
