供应商必须提供设计,并完成管道（材料由ZPSS公司提供）与所有大楼内外由其设计的设备之间的互相连接.
分析句子结构:
句子主语:SUPPLIER(供应商)
谓语:will provide (提供),以及 complete(完成)
宾语:design(设计),for interconnection(互相连接)
although the piping materials are supplied by ZPSS是状语(让步状语),表示连接的管道虽然不是supplier(主语)提供,而是由ZPSS提供的
(interconnection) with related to all SUPPLEER designed equipments (whether they are located inside or outside of the building)
介宾结构作interconnection的定语,什么的相互连接,与equipments(设备),什么设备,有两个定语-1.all SUPPLEER designed,所有供应商设计的,2.whether they are located inside or outside of the building,不管是大楼内部还是外部的
