A单位承建一项污水泵站工程，主体结构采用沉井，埋深l5m。场地地层主要为粉砂土，地下水埋深为4m，采用不排水下沉。泵站的水泵、起重机等设备安装项目分包给B公司。在施工过程中，随着沉井入土深度增加，井壁侧面阻力不断增加，沉井难以下沉。项目部采用降低沉井内水位减小浮力的方法，使沉井下沉，监理单位发现后予以制止。A单位将沉井井壁接高2m增加自重，强度与原沉井混凝土相同，沉井下沉到位后拆除了接高部分。 B单位进场施工后，由于没有安全员，A单位要求B单位安排专人进行安全管理，但B单位一直未予安排，在吊装水泵时发生安全事故，造成一人重伤。工程结算时，A单位变更了清单中沉井混凝土工程量，增加了接高部分混凝土的数量，未获批准。指出A单位变更沉井混凝土工程量未获批准的原因。
