问答题 案例分析题

某机电工程施工单位承包了一项设备总装配厂房钢结构安装工程。合同约定,钢结构主体材料H型钢由建设单位供货。根据住建部关于《危险性较大的分部分项工程安全管理办法》的规定,本钢结构工程为危险性较大的分部分项工程。施工单位按照该规定的要求,对钢结构安装工程编制了专项方案,并按规定程序进行了审批。 钢结构屋架为桁架,跨度30m,上弦为弧线形,下弦为水平线,下弦安装标高为21m。 单片桁架吊装重量为28t,采用地面组焊后整体吊装。施工单位项目部采用2台起重机抬吊的方法,选用60t汽车式起重机和50t汽车式起重机各一台。根据现场的作业条件,60t起重机最大吊装能力为15.7t,50t起重机最大吊装能力为14.8t。项目部认为起重机的总吊装能力大于桁架总重量,满足要求,并为之编写了吊装技术方案。 施工过程中发生如下事件。

事件1:监理工程师审查钢结构屋架吊装方案时,认为若不计索吊具重量,吊装方案亦不可行。

事件2:监理工程师在工程前期质量检查中,发现钢结构用H型钢没有出厂合格证和材质证明,也无其他检查检验记录。建设单位现场负责人表示,材料质量由建设单位负责,并要求尽快进行施工,施工单位认为H型钢是建设单位供料,又有其对质量的承诺,因此仅进行数量清点和外观质量检查后就用于施工。

事件3:监理工程师在施工过程中发现项目部在材料管理上有失控现象,钢结构安装作业队存在材料错用的情况。追查原因是作业队领料时,钢结构工程的部分材料被承担外围工程的作业队领走,所需材料存在较大缺口。为赶工程进度,领用了项目部材料库无标识的材料,经检查,项目部无材料需用计划。为此监理工程师要求整改。

事件2中,施工单位对建设单位供应的H型钢放宽验收要求的做法是否正确?说明理由。施工单位对这批H型钢还应做出哪些检验工作?
