However, forming the tower's core after the steel frame had been erected created further logistical challenges — with the core's formwork needing to be small enough to navigate through the steel structure to the core's location.

然而，在钢框架搭建完后，形塔楼的部分带来了进一步的后勤挑战——模需要足够小，才能穿过钢结构到达部分的位置。

3D printers can construct buildings without formwork (the concrete molds that cement is typically poured into), which can significantly reduce overall use of the material.

3D打印机可以在没有模（通常用于灌注水泥的混凝土模具）的情况下建造建筑物，这可以显著减少材料的总使用量。

After careful planning, and with approvals in place from city authorities, formwork systems manufacturer PERI delivered One Vanderbilt's core forming system under the cover of darkness to avoid disruption.

经过精规划，并获得市政当局的批准，模制造商 PERI 在连下交付了 One Vanderbilt 的型，以避免项目中断。

As each storey of the core is completed, PERI's innovative climbing sequence transfers the load of the formwork system from the upper working brackets, shown here in red, to the lower climbing brackets, shown in yellow.

随着层的每一层的完，PERI 创新的攀爬顺序将模的负载从上面的工作支架（这里显示为红色）转移到下面的攀爬支架（这里显示为黄色）。

With the initial core walls poured, PERI's ACS Core 400 formwork system was maneuverered through One Vanderbilt's steel frame and installed.

在开始浇筑墙时，PERI 的 ACS Core 400 模通过 One Vanderbilt 的钢框架进行操作和安装。

First, we 3D printed the formwork for the exterior concrete shell, as well as a mold for the inside, so we could easily lay out the dowels in place.

首先， 我们用3D打印技术制作了外部混凝土壳的模，以及内部的模具， 这样我们就能方便地将木钉准确放置到位。

It requires 7 inches to vibrate it properly, and a plastic formwork is needed to make the concrete smooth.

它需要7英寸来使其正常振动，而且需要塑料模来使混凝土表面光滑。

Perry was used here, which is considered the best formwork.

这里使用了佩里模，这被认为是最佳的模。

It looks like it could be rammed Earth, which is a pretty ancient construction technique, very popular in drier and hotter parts of the world where you grab damp soil made from aggregates, sand, silt, clay and gravel into a formwork.

看起来像是夯土结构，这是一种相当古老的建筑技术，在世界上较为干燥炎热的地区非常流行。在这些地方，人们会将由骨料、沙子、粉砂、黏土和砾石组的湿润土壤填入模中进行夯筑。

For example, I once redesigned a contractor's formwork system with a supplier, cutting material costs by 8%.

例如，我曾经与一家供应商合作重新设计了承包商的模，从而降低了8%的材料本。

That is, they are currently laying out reinforcement mesh and have set up the formwork.

也就是说，他们目前正在铺设钢筋网，并设置了模。

I think the concrete must have been formed using fabric as a formwork, and it conducted heat from the sunlight.

我认为这混凝土必定是用织物作为模浇筑而，并且它还能传导阳光的热量。

In a monolithic house, you can always see traces from the formwork fastenings, like these holes, which are usually filled in later, but some of these holes were intentionally left open.

在整体混凝土房屋中， 你可以总是看到模固定痕迹，比如这些孔洞， 这些孔洞通常会在后期被填满，但有些孔洞是故意留下的。

The formwork between them was only recently removed.

他们之间的模最近才被拆除。
