Technologies for situated learning, intergrated design and collaboration

许多报告和研究都认识到，建筑业在按时按预算交付优质产品方面表现不佳。一些人将这个问题与建筑物的规划、设计和交付方式联系起来。建筑商不参与设计过程，设计工作在不同专业之间分散，导致缺乏迭代，缺乏对后续阶段限制因素的考虑，缺乏领导力和问责制。这导致了次优的解决方案、较差的可施工性和可操作性、设计和施工中的返工以及缺乏创新。这些问题在可持续建筑中更为关键，因为在可持续建筑中，需要更多种类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.
