Agenda Item:
Report on project and motion approving Change Orders for All Seasons Arena.
Recommendation/Action(s):
Motion approving change orders.
Summary:
The All Seasons Arena project continues to progress; however, several issues have been discovered over the course of the summer. Unfortunately, this has pushed our scheduled completion for Phase 1 back roughly 7 weeks. Some of the large and impactful issues have included elevated water levels under the south rink floor, insufficient concrete edge around the south rink perimeter, and no topping layer on the precast concrete planks that make up the second floor. Staff, along with the design team and contractors, have developed solutions to each of the identified issues and work is continuing to move forward towards a new completion goal for Thanksgiving.
Expansion
The expansion for the ice plant room is progressing and received its rubber roof in early September. The underground work in the room is complete, and the concrete floor was poured in mid-September. The room is now weather tight with the equipment pads poured, and the epoxy flooring scheduled for the week of October 14. Equipment will begin being delivered the following week.
South Rink Reconstruction
The rink contractor has completed the concrete perimeter, allowing for the proper thickened edge as well as the drain tile under the rink to ensure a dry subgrade to build the new rink floor. The rink floor is anticipated to be poured in late October and requires a 28-day cure time. Staff have worked out a plan with the testing firm and the contractor to cast several extra concrete cylinders which will be tested starting at 21 days. If the concrete reaches its required strength ahead of the 28 days, then the rink will be turned over to staff to start the ice building process.
We are also identifying options for hiring a contractor to bring in specialized equipment to assist in the ice building process to allow for near continuous operation and remove that burden from the operations staff.
South Rink Remodel
The general contractor is progressing with the remodel. A resolution has been designed for the lack of topping on the second floor precast concrete floors that includes a thin application of a cement product that was limited to less than 1 ½” due to weight concerns. The original plans from the manufacturer in Savage were procured in order to calculate the rating of the existing panels. With that finalized, work is advancing quickly with nearly all the mechanical and plumbing rough-ins completed. Drywall has been installed and painting is currently underway. Staff is coordinating the licensing and inspection process for the concession stand to coincide with the completion of construction.
Staff is recommending approval of the following change orders.
