Seattle Public Schools

Seattle, WA

The Adams Elementary School Modernization made valuable upgrades to this complex existing 1970 building and its 1988 addition, extending its useful life for many years for the community it serves. Modeling and life cycle cost analysis confirmed that a geothermal system with 80 wells, efficient heat pump HVAC units, and new code compliant R-38 roof insulation would offer the biggest energy savings per budget dollar spent, while seismic analysis and review of complex roof transitions led to the right details for zero impact to the building interior and respectful, minimal modification of its exterior appearance.

In order to leave open the possibility of additional beneficial scope, DOWA-IBI worked with the district to develop a number of alternates with a priority system for selection. With positive bid results, this enabled Seattle Public Schools to select a more robust roofing system, expand replacement to the entire roof system and fully upgrade all roof seismic diaphragms, add valuable roof access ladders and fall protection for maintenance staff, and replace aging penthouse stucco finishes with metal panel for greater longevity. All of these improvements were achieved at a cost 8.37% below the original project budget, a spectacular result for the school, district, and larger community.
