Updates

• November, 2012.
  • After 4 meetings, no consensus has been made on whether the home side stadium will be on the east or west side of the field.
  • At meeting 4, Skyline Gridiron Members propose Design-Build option stating impression that project can be designed and constructed in a 5 month time frame so that football season can continue without interruption.
  • At meeting 4, Skyline Gridiron presents a design for stadium that includes a full basement requiring an elevator which the District and school staff does not want included in the package and stated as early as the first meeting.
  • After meeting 4, District puts Bassetti on hold until more information is gathered on Design-Build option.
  • District has determined that Design Build is not the most appropriate alternative contracting method for the project. The District has submitted an application to use GC/CM to CPARB. Application presentation will be 11/29/2012.
  • Meeting scheduled 11/7 at which time Steve will present GC/CM process and timeline and will review Design-Bid-Build options for Committee consideration.
  • Starting 11/8/2012, some Design-Bid-Build options could be completed prior to the 2013 football season. The GC/CM option requires time for the GC/CM selection process. Assuming approval to use GC/CM on 11/29/12. The selection process would be completed in mid-March. Design work could restart at that time with the Hainline & Associates schedule showing substantial completion in mid-January 2013. That schedule requires a winter construction schedule that could add to construction costs.
