What Does a Geotechnical Engineer do?
Will there be basements, multiple stories, grade changes, or special features on your proposed building project? One thing you may not be aware of is the tremendous value geotechnical engineers can bring to a project by selecting optimum foundations and site preparation techniques. They collect soil samples at critical depths for laboratory testing and explore various locations on the site to identify the greatest efficiency and can also provide guidance and recommendations to confirm a building or structure is compatible with the underlying soil. Earth is not a very sympathetic negotiator, so it is prudent to select a site improvement or foundation method that will be reliable at the lowest practical cost.
实现成本节约
有一种艺术来支持普遍的宽容,潜在的节省可以很高。通过正确的方法,岩土工业顾问可以证明轴承压力是3倍,比雷竞技的电竞比分网保守报告中推荐的典型值高三到四倍。具有讽刺意味的是,取样的成本或in-situ testingrequired to justify higher bearing pressures is probably less than one deep foundation element.
该网站可以通过脂肪粘土来下降吗?楼层平板或基础将经验的潜在升降与若干因素有关,包括目前的土壤水分含量,土壤可塑性和特定类型的粘土土壤。目前,许多顾问会自动建议校正5英尺以下楼层和基础。可以基于一些可以向报告添加几百美元的简单测试来评估适当的过度过度的过度扫描。但在整个建筑物上通过一两英尺减少过度扩张和更换体积,同时将基础留在原生土地上的基础中可能意味着在甚至是一座小型建筑物中的成本节省成本。
创造清晰度,减少混乱
项目团队通常由建筑师领导,该建筑师为结构,民用,机械和电气系统选择受信任的设计师。考虑在项目的开头和整个设计和建设中,认为包括岩土工程师包括岩土工程师,这是一个很好的想雷竞技的电竞比分网法。在设计进度期间,岩土工程顾问可以指导其他设计师,因为项目雷竞技的电竞比分网的细节最终确定。通常,设计师努力实现由于多种原因提供的建议。也许原始报告是为先前的建筑配置编写的,更改使这些建议不再适当。另一个例子是,所有者通常指示设计者选择在施工期间将确认的低轴承压力,并前述岩土性评估。雷竞技的电竞比分网由于该项目的设计和实际构建,因此遇到的任何问题都会花费额外并导致延迟。岩土内报告的成本与在设计阶段进行雷竞技的电竞比分网工作大致相同。
通过岩土,民用,结构和机械工程师准备了明确和协调的规范,创造了清晰度并减少了混乱。雷竞技的电竞比分网混乱影响项目时间表,承包商将保守地投标,如果他们不确定该怎么办。岩土工程雷竞技的电竞比分网师经常不会参与编写规范和规划票据,但可以快速证实它们符合项目的岩土建议。一致的术语,定义和方向是关键。
质量是适应性和效率的关键
目前的趋势是根据提供的范围征询岩土专业顾问的三个出价,并根据最低价格选择顾问。雷竞技的电竞比分网仅基于最低价格选择岩土专业顾问的趋势导致轴承压力保雷竞技的电竞比分网持非常保守,需要大规模的过度扫描和置于潜在麻烦的迹象。仅对价格竞争,博格,实验室检测和工程努力的数量被危险地减少赢得项目。基于这些保守建议的额外意外的建筑成本和进度延误通常超过项目开始时进行了周到的地下勘探和工程评估的成本。
Hiring the geotechnical engineer with the design team to review the final building layout may result in changes that will improve constructability and efficiency. Value engineering ideas are often realized when a geotechnical consultant is engaged throughout the design and bid process. When selecting a member of the project team, include the geotechnical engineer and strive for quality with the understanding that their expertise can add value to your final project.
