Conceptual Pricing

The costs for the various PDP Options indicated below are intended to be an analysis of the relative costs between options and NOT a prediction of the actual final cost of any individual option. Major variables such as geotechnical, site grading, wetland determination, structural system and final MEP systems have yet to be designed and costs will vary significantly from the benchmark cost estimating included as part of this PDP cost analysis. The costs outlined in this report should not be represented as the FINAL construction budget and have a +/- 10% degree of accuracy.

PDP estimates utilize SF data from all recent high schools

Swimming Pools – MSBA will only allow if separate project, separate funding, and ballot vote
Skating Rinks
Field Houses (Field houses have a track vs Gymnasium) MSBA will only allow if separate project, separate funding, and ballot vote

MSBA Policies

The Following Spaces are subject to size limits

Auditorium shall be no more than 13,300 nsf (based upon upper limit of 1,000 seats)
Gymnasiums – The district may choose to build a gymnasium and associated spaces, but in no event shall the gymnasium exceed 18,000 nsf. The MSBA will participate in a gymnasium of up to 12,000 nsf unless adjusted by the MSBA to increase teaching stations for enrollment and/or the educational plan.
Areas in excess of the MSBA guidelines will be at the sole expense of the district;
Community support must be demonstrated prior to MSBA approval of a district’s proposed project scope and budget
The MSBA will exclude from its grant the cost of the total gross square foot (“gsf”) above guidelines for these areas. Total NSF over MSBA limits x 1.5* grossing factor. This amount will not change over the term of the grant even if the bids come in at a lower amount.

* Grossing factor to be determined at end of schematic design
