This meeting is a revisit of the requirements gathering exercise for the Isi Mobile garage, with the main goal of closing the budget gap between the cost determined for the initial concept for the garage (cost estimates have been provided by CPS and a second engineering firm) and the budget. It should be noted that this gap was projected to be substantial, with RSL looking for procurement cost not to exceed $750K and a strong preference for something closer to $500K expressed. The concept design that came out of the series of exercises over the past months was almost $900K over the RSL ceiling, hence more than $1.3M higher than ideal target.
15 possible options for reducing costs were discussed, with two major cost-savings options discussed at length: 1. reducing the square footage and 2. creating a series of smaller buildings to house the separate components of the garage, assuming that the individual pieces could be procured in different years to spread the cost. The main consensus was that breaking the project into smaller pieces to spread the cost was not viable. Therefore we need to redesign the concept to include just a single working bay in the garage based on the width and height of the widest and heaviest tractor, and the length of the longest tractor. This should reduce the overall size of the sled mounted garage by approximately half compared to the concept, which included space to store the 2006 Tucker and 953 loader, and also a maintenance bay for the largest piece of equipment on station.
Noted that if cost scales directly with square footage of heated space, this reduction in scope would still leave budget gap of well over $100k so other possibilities moving forward to reduce costs include having a separate generator module, removing the mezzanine, reducing the R-factor to R40 or below, and using non-metal flooring for areas outside where the vehicles would be moving.
While not discussed very much during the call, the reduced scope of the new garage concept does not include any shared space for science, especially including balloon launching. It has been recognized that Isi will probably need some kind of surface science space for summer campaign work and year-round balloon launching, but we need to find an option to support these functions during the transition to Isi from Summit (as soon as SOB is decommissioned, possibly as early as 2015.
