Geodesic design and the use of concrete effected notable savings in the construction of Seattle's new $1,768,083 Mountlake Terrance Senior High School. The architect credits an estimated $40,000 savings in over-all costs to the unusual circular shape and to the choice of concrete as the building material. He explains that a circular design gives the smallest number of lineal feet of wall to enclose a given space. The $13.85 spent per square foot is well below the Washington state matching limit of $13.96 a square foot. The school, with 128,922 square feet of usable space, was built at a per pupil cost of $1,786.08, also below state limits. Total cost included a 6 percent architect's fee, a 4 percent state sales tax and all additional items such as landscaping. Construction involved the application of exterior walls consisting of 6 inch thick tilt-up panels of concrete faced with crushed white marble to provide an attractive, damage proof, no maintenance exterior. The panels were cast at the site in wooden forms on pretreated floor slabs. Steel reinforcement was added, the white crushed marble applied, and the panels were then raised into place by huge cranes.
