Millennium Partners' Winthrop Center tower is making waves, and not just for its attempt to meet some of the world’s must vigorous environmental standards.

Suffolk and subcontractor S&F Concrete Contractors installed the 20-million-lb concrete slab, also known as a transfer mat, without a hitch after intensive planning and preparation involving various subcontractors and trades.
The work took place in a limited space 350 ft in the air, and required nine levels of shoring compared to the typical five. It also had to be kept in place for 21 days.
萨福克项目主管约翰·纽霍尔（John Newhall）说：“那里的情况非常非常好。”
该垫子需要1200吨钢筋，旨在解决塔楼设计产生的问题。该结构分为两部分：812,000平方英尺的办公空间，顶部为572,000平方英尺的住宅空间，分为321个单位。
To make the offices more attractive to corporate tenants, the lower floors will have open floor plans spanning 45 ft and relatively few supporting columns and walls.
However, the residential section above, which is much more densely packed, will need support.
转移垫提供了解决方案，实际上将塔顶的住宅区的重量转移到下面办公室部分的间隔外围柱上，从那里到达地面。
纽霍尔说：“这是这座城市第一次在这里完成。”“没有那么多大建筑物，您有这样的混合分手。”
