Thornton Tomasetti used SAP computer models to perform an analysis for the $23 million rehabilitation and equipment upgrade of the Roosevelt Island Tramway, for which we were the original engineer. We worked within a tight design and construction schedule to accommodate heavier loads created by new tramway cables, cars and machinery, designing tower and station reinforcements as well as completely new steel head frames for each of the three towers. Our work also took into consideration new wind, earthquake, ice and snow codes that affect the highly active tramway, whose two cabin cars make more than 115 trips per day.
