4.3 买方应尽可能合理安排建筑与土木工程的施工进度以确保设备的安装及时准确。但是，在整体结构上钻孔，临时切口等导致中断而产生的成本，以及工程建设竣工开张的延期产生的额外费用都应由土建承包商负责。
4.4 在买方的监督下由供应商提供全部必需的工作，监督和服务并进行润滑和冲洗。所有的设备安装和设备润滑的工作需按照买方的要求由承包商执行，直至设备经买方验收成功。
4.5 设备的供应包括泵、管路、软管，阀等任何所需测试的全部设备。电器连接、水供应，进行测试及水处理应属于买方的责任范围。
4.6 所有设备的钢结构支架的安装，除说明书中标明不作提供，或者没有必要进行安装，承包商必须按照我方提出的要求进行施工。
4.7 必要时应进行锚栓或嵌入钢材的安装，承包商在水泥地基中的预铸造锚栓除外。
4.8 用所需销与轴键固定设备的相关说明。
4.9 全部基板薄垫片的安装以及必要的机械包装。承包商负责适当的设置，测量及布线和灌浆工作并在其指示下更换。
4.10 在槽底切割临时开口。即：以灌浆为目的，并在灌浆结束后关闭开口。
4.11 工程范围内全部所需涂装工作的运用。
5. 材料与工艺
5.1 排线与标线测量
5.1.1 所有设备必须根据安装工程实践和制造方的说明进行安装。
5.1.2 用光学/激光方法检验布线和测量。必要时将按照买方的判断或传统程序来执行以确保安装的顺利执行。
5.1.3 设备的定位公差应符合制造商建议并通过买方的批准。电动发动机和基板之间的薄片要谨防腐蚀，并注意安装多个发动机时所需的间隔公差。
5.1.4 所有的齿轮减速器，基部安装的联轴器及其他大于4千瓦的驱动器都必须在最终布线后用暗销安全固定。
