建筑工程质量保证和质量控制(QA/QC)中，房屋检验起着至关重要的作用。在实践中，鼓励团队共同审查竣工信息并协调搜索差异的情况下进行协作检查。在这一过程中，沟通被认为是不可或缺的。然而，现有的方法没有明确定义在各种建筑物检查情况下，什么级别的通信是足够的，而不是多余的。过多的交流可能会导致信息过载和群体两极分化。信息过载是指感知到的输入信息超过了人类的认知能力，影响了决策质量；群体极化是指一群人聚集到一个占主导地位的团队成员持有的中心观点的趋势。本研究验证了一种假设，即协同建筑检测中的过度沟通会影响建筑检测的绩效。作者进行了一项人体实验(n=71)，以比较允许通过口头交流交流信息的小组与独立进行审查和检查的小组的建筑检查表现。一个多用户虚拟现实(VR)模型使用德克萨斯农工大学校园内的一栋真实建筑作为试验床，以方便复习环节。作者记录了确定的差异数量作为绩效指标，包括建筑、结构和MEP差异。研究结果显示，实行独立审查和检查的小组表现优于允许进行口头交流的小组。虽然其他因素(例如，测试对象在建筑物检验方面的经验水平)受到控制，但观察到的明显表现表明，沟通可能在一定程度上影响建筑物检验质量，或者团队中的某些“统治者”往往会误导讨论。另一个原因可能与被检查的建成资产的复杂性有关。为了进一步了解这种团队检查业绩的恶化，有必要进行进一步的调查。
Building inspection plays a critical role in the quality assurance and quality control (QA/QC) of building construction projects. In practice, collaborative inspection is encouraged where a team co-review the as-built information and coordinate searches for discrepancies. Communication is considered as indispensable in this process. However, no existing methods clearly define what level of communication is sufficient but not redundant in various building inspection scenarios. Too much communication may lead to information overload and group polarization. Information overload refers to cases where perceived input information exceeds human cognitive capacity that affects decision quality; group polarization refers to the tendency for a group of people to converge into a central opinion held by a dominant team member. This study tested a hypothesis that excessive communication in collaborative building inspection compromises the performance of building inspection. The authors conducted a human-subject experiment (n = 71) to compare the building inspection performances of groups that were allowed to exchange information via verbal communications against those of groups conducting review and inspection independently. A multi-user virtual reality (VR) model uses a real building on Texas A&M University campus as the testbed to facilitate the review session. The authors documented the number of identified discrepancies as the performance indicator, including architectural, structural, and MEP discrepancies. The research results showed that groups practicing independent reviews and inspections outperformed groups allowed to have verbal communications. While other factors (e.g., the experience level of test subjects in building inspection) were controlled, the observed distinct performance suggests that communication may compromise building inspection quality to some extent or certain “dominants” in teams tend to mislead the discussion. Another reason might be relevant with the complexity of inspected built assets. Future investigations are necessary to comprehend such team inspection performance deterioration further.
