OakPark Comparison to Turner Plan

New construction for the OakPark plan calls for six new classrooms and a large Media Center. Renovation of the existing Administrative, Gym and Support services is more economical than building a new building for these functions. There has been completed in 2007 the replacement of the Gym roof and wall for a project savings of $174,000. The Turner plan called for new construction of areas for Administration, Health Services, Art, Gym, Kitchen and Special Education, and six new classrooms. This would cost $1,807,000 more than renovating and modifying these areas

The OakPark proposal for the 1920’s building adds a new electrical service, air conditioning, windows, sprinklers and re-furbishing, while Turner would only renovate to code the whole building. This would cost $139,000 less than the OakPark plan.

Site costs are lower for OakPark mainly because there is no demolition and carting away cost. The Turner excavation cost is significantly higher for the large addition that includes removal of the 1950’s building and construction of a large new building. The Turner plan put the playground equipment on the hill in the back of the school.

The Turner proposal provided no detail for soft costs, only that they were calculated at 27%. One item is described as an additional Project Contingency @ 7.5% or $623,000. Without this item the percent would have been 19.5%. OakPark soft costs are 17.7% of a lower construction cost.

The escalation amount for Turner is 9.8% over a two year period at the higher project cost while the OakPark escalation is 8% for one year at the lower project cost and the accelerated time line for completion of the project. Since the construction bids become fixed after the first year, the Turner escalation amount is overstated by $372,000 for the second year.

This comparison is to the Turner proposal presented one week before the final report. The new Addition was then reduced to 21,000 Sq ft by removing the Media Center and putting it in the 1920’s building. The Media Center would have been the combination of the 3 classrooms on the first floor. The renovating to new of the whole building for an increased cost of $900,000 became necessary. Support service space is gone and there is no school during re-construction.
