财产重建可能是一项棘手的业务。对于具有工业用途历史的地点尤其如此，这些网站受到不受控制的填充，建筑材料，废弃的结构和公用事业和工业废物的影响。将这些材料放在地下水表面附近或下方，你有一个啤酒。处理此类影响并不便宜，但许多项目产生了不必要的成本，因为它们并未与共同的环境和岩土技术的角度协调。manbet万博app超额成本来自两个来源：
- Basic site investigation rework
- Failure to leverage both environmental and geotechnical expertise when evaluating site redevelopment alternatives
Rework is generally the product of poor logistics or inexperience and can be mitigated through better planning. Leveraging environmental and geotechnical expertise requires more experience, a solid understanding of regulations governing design and construction, and industry savvy.
Collaboration During Site Investigation
Environmental professionals characterize environmental site contamination as well as develop and perform remediation plans—it’s what they were trained to do. But many environmental site investigations come up short on difficult sites. Site contamination is often characterized with little or no thought regarding how the contaminated material(s) can be avoided, relocated, repurposed, etc., to support redevelopment. As a result, geotechnical consultants often redrill at additional cost to obtain geotechnical information that should have been gathered during the environmental investigation.
同样，虽然岩土工程师们了解所需的所manbet万博app需的地质地质条件，以支持建筑物和人行道的建造，但他们经常无法识别与在表面特征（废弃燃料泵），钻孔样品中可能明显的环境问题有关的项目的潜在影响（有气味或变色的土壤）或测试坑（夹带拆除碎片）。无论是环境还是岩土工程，这种遗漏都可以毁了一个项目manbet万博app。
Intertwined Design
Once a site has been characterized, it is critical to understand all environmental and geotechnical constraints, how they affect each other, and how they affect the project’s bottom line cost and the risk of future structural problems. Unfortunately, the traditional environmental investigation and remediation process doesn’t do this well on its own, nor does conventional geotechnical engineering.
For example, environmental consultants can rigorously delineate limits and estimate the volume of uncontrolled fill impacted with chemicals at concentrations above applicable regulatory standards, but what are the disposal options once it’s excavated? Are there options for on-site relocation of the fill that won’t limit redevelopment options or prevent redevelopment from occurring at all? And what about sites with uncontrolled fill impacted by contaminated groundwater? Is there a ground improvement or building support alternative available to reduce or eliminate groundwater management costs associated with dewatering?
These questions can pose complex challenges. This is where experience and industry savvy come into play. For instance, it may be possible to place fill containing construction debris outside foundation oversize planes and/or at depth below pavements to reduce potential impacts to building or pavement performance. Many times, additional excavation work can be performed to accommodate placement of contaminated soils at depth below buildings or pavements to prevent off-site disposal of contaminated soils.
将建筑障碍与经验丰富的员工一起移动
No matter how well a site is characterized, unforeseen conditions are possible, even typical. Most building contractors are not trained to think about environmental issues, but are focused on the myriad of details related to construction of the new structure and associated infrastructure. That is why it is critical to have experienced field staff present during construction who understand both the environmental regulatory framework and the plans for building construction. The presence of experienced field staff facilitates prompt resolution of minor issues and proper assessment and communication of larger issues. They are the first line of defense when these issues arise in the field.
It is critical to bring environmental and geotechnical professionals together early in the planning process for redevelopment sites. Working together, these professionals can design field investigations that capture as much environmental and geotechnical information as possible.
