for delivery是什么意思

问题描述

By packaging large pieces of the high-speed rail line together, for delivery by a single contractor, the project’s cost and constructiontimeline would be greatly reduced, the team proposed.

疑问 for delivery 在这句中什么意思？由于传给一个承包商？

老师答疑

刘老师：

你的理解正确。通过将大量的高速铁路线打包，交付一家承包商承建，该项目的成本和施工时间将大大降低，该团队建议说。

z老师：

同意“英语问答”老师的看法；我想补充的是：该句能理解成 The team proposed (that) the project's cost and construction time line would be greatly reduced by packaging large pieces of the high-speed rail line together,and for delivery by a single contractor. 其中by doing---用作方式状语；for ----用作原因状语。
