Technologies for situated learning, intergrated design and collaboration

许多报告和研究承认，建筑业在按时和按预算交付高质量产品方面表现不佳。一些人将这个问题与建筑的规划、设计和交付方式联系在一起。建筑商没有参与设计过程，专业之间的设计工作支离破碎，导致缺乏迭代，缺乏对后续阶段的限制考虑，缺乏领导力和问责制。这导致解决方案次优，可施工性和可操作性差，设计和施工中返工，缺乏创新。这些问题在可持续建筑中更为关键，因为在可持续建筑中，需要更多的专业知识才能以具有竞争力的价格实现预期的性能。

Numerous reports and studies recognize the construction industry poor performance in delivering a quality product on time and on budget. Some associate this problem with the way building are planned, designed and delivered. The non-involvement of builders in the design process and the fragmentation of the design work between specialties engender a lack of iterations, a lack of consideration of constraints within subsequent phases and a lack of leadership and accountability. This leads to suboptimal solutions, poor constructability and operability, rework in design and construction and lack of innovation. These problems are more critical in sustainable construction, in which a larger variety of expertise is required to achieve the expected performance at a competitive price.
