问题:

1,施工单位自行覆盖,浇筑混凝土是否合理?请说明理由。

2,施工单位拒绝是否合理?请说明理由。

3,本案,若对该主梁进行钻孔重新检查,由此增加的费用,延误的工期谁承担?

答:1,施工单位自行覆盖合理

因为根据规定,监理单位未在约定的时间内对隐蔽工程进行检查和验收又没有提出延期要求,视为隐蔽工程检查合格,施工单位可自行隐蔽覆盖并作相应记录,监理单位应予以签收。

2,施工单位的拒绝不合理。

因为根据规定,隐蔽工程隐蔽后,监理单位对隐蔽部位质量有怀疑,有权要求施工单位钻孔探测或剥开重新检查,施工单位应遵照执行,并在检查后重新覆盖恢复原状。

3,①重新检查合格的,由此增加的费用,工期由建设单位承担,并支付承包人合理利润。

②重新检查不合格的,由此增加的费用,工期由施工单位承担。

因工期十分紧迫,主体结构施工至15层时,施工单位项目负责人在质监交底上提出分阶段进行主体验收,以便装饰装修工程提前施工,遭受质监人员的拒绝。

XXThe person in charge of the construction unit will organize the relevant personnel of the supervision unit, the project leader of the construction unit and the project technical person in charge to carry out the main experience and find that there are left wall bolt holes left on the shear wall.

At the main project acceptance meeting hosted by the project unit project leader, the chief management engineer raised the problems found during the acceptance process and proposed rectification opinions.

Question: It is reasonable for the quality supervision personnel to refuse to carry out the main experience in stages, explain the reasons; point out the inadequacies in the main experience, and give the correct approach.

A: (1) Reasonable.

Because according to the regulations, if it is necessary to carry out the acceptance of the main project in stages, the project leader of the construction unit shall submit a written application to the quality supervision personnel at the quality supervision and delivery, and the quality supervision personnel shall agree.

(2) Something is wrong:

1 Only the construction unit, supervision unit and construction unit participate in the acceptance of the main project is not appropriate.

The correct approach is that the design unit should also participate in the main experience.

2 The construction unit only accepts the acceptance of the main project by the person in charge of the project and the person in charge of the project.

The correct way is that the person in charge of the technical and quality department of the construction unit should also participate in the acceptance of the main project.

3 There are left holes in the wall on the shear wall.

The correct way is that before the acceptance of the main project, the construction holes on the wall shall be inlaid and compacted according to the regulations, and the concealed project acceptance records shall be made.

4 The main project acceptance meeting hosted by the person in charge of the construction unit project is not appropriate.

The correct approach is to accept the acceptance meeting of the main project by the team leader, that is, the chief engineer or the project leader of the construction unit.

xx因混凝土结构存在裂缝等严重缺陷,验收组要求相关单位处理,施工单位提出技术处理方案后经过监理单位和建设单位认可后进行处理。因勘察单位没有参加验收,当地的质监站对此提出异议

问题:指出上述不妥之处,并给出正确做法;主体工程验收时实体检验项目还有哪些

答:(1)不妥之处有:

①施工单位自行实施混凝土现浇结构的实体检验不妥。

正确做法为:结构实体检验应由监理单位组织施工单位实施,并见证实施过程

②施工单位对混凝土强度进行检测不妥。

正确做法为,除结构位置与尺寸偏差(该项目可由施工单位检验)外,其他项目应由具有相应资质的检测机构完成。

③用标准条件养护试件对混凝土强度进行检测不妥。

正确做法为,结构实体混凝土强度检验宜采用同条件养护试件方法;当未取得同条件养护试件强度可采用回弹 - 取芯法进行检验

④施工单位对混凝土结构存在裂缝等严重缺陷的技术处理方案后经过监理单位和建设单位认可

后进行处理不妥。

正确做法为,该技术处理方案还应经过设计单位认可。

⑤质监站对勘察单位没有参加验收提出异议不妥。

正确做法为:主体结构的验收勘察单位可不参加

(2)钢筋保护层厚度,结构位置与尺寸偏差,合同约定的项目。
