Special Inspections: Consistency in Design

在大多数商业和多租户住房项目的施工过程中，建筑规范要求进行特殊检查和测试（SI&T）。专项检查多对基础、钢材、砌体、混凝土等结构构件进行；如果不进行这些检查，可能会导致危及生命的问题。特别检查的目的是使业主、设计师和建筑官员有信心知道正在建造的与最初设计的一致。

One of the requirements of special inspections is that the firm is retained and paid for by the owner or design team. The contractor should not retain the SI&T, primarily to avoid a potential conflict of interest. When selecting a firm, the two questions owners frequently ask are: How much will it cost, and who should I hire?

要多少钱？

The American Council of Engineering Companies provided guidance on these fees. For typical structures on a site with good soil conditions, budgeting 1/4 to 1/3 a percent of construction costs is a good place to start. For sites with poor soils that require deep foundations, large soil corrections or large multi-level reinforced concrete structures, 1/2 to 2/3 of a percent of the budget should be set aside for SI&T.

Who should I hire?

When selecting a firm, you should consider the continuity of geotechnical responsibility for the individual performing the SI&T. Given the risks of soil-related cost overruns during construction, involving the same geotechnical engineer during construction can provide valuable consulting when unanticipated conditions occur. They can also assist the construction team in evaluating if what is being built is consistent with the original geotechnical design. Another important factor in selecting a firm is confirming that the individual performing the SI&T is qualified. The Building Code requires that this be demonstrated through training and experience in successfully performing SI&T on similar projects.

特别检查员具有重要的作用，应该是施工团队的一个组成部分，因为他们必须与建筑官员、结构工程师、建筑师、承包商和业主进行沟通。虽然我们有幸在明尼苏达州有许多优秀的承包商，特别督察提供宝贵的帮助，以帮助捕捉错误时可能发生的结构。有关更多信息，请致电952.995.2386与克里斯托弗·凯尔联系。
