Development of cloud-based collaborative BIM modelling software

在加拿大，建筑从业者、研究人员和建筑的其他利益相关者越来越认识到需要改变家庭建筑方法。多年来，汽车行业一直享受着自动化设计和制造的好处，现在是时候推动同样的自动化向家庭建筑行业发展了，因为熟练劳动力短缺，对经济适用房的需求也很高。对现有设计和起草产品的扩展(即由应用程序编程接口实现的附加组件)的需求越来越大，以满足模块化建筑行业的特定需求，以及旨在多个项目利益攸关方(例如，消费者和建筑设计师)之间直接协作的基于云的信息共享环境。因此，这项研究的目的是开发基于云的建筑信息建模(BIM)工具，供不同技能集的用户协作编辑和共享模型，从消费者到专门小组的家居设计师、估价员和生产经理。为了实现拟议的目标，将进行三项活动：(1)将合作公司(Cadsoft Corporation)的代码库迁移到面向服务的架构；(2)实时协作模型编辑；(3)以自动化制造为中心的BIM。可以预期，通过该项目，行业合作伙伴可以通过重新定义他们当前的BIM软件而受益，建筑行业可以提高其设计和起草、决策和生产的生产力和效率。提出的研究将形成一个适合模块化/板条化建筑行业的BIM系统，优化项目的材料利用，减少施工过程中产生的碳化学排放。这些共同努力将增加住房行业的劳动力，将导致住宅建筑商更广泛地采用Cadsoft的Envisioneer软件，并将在制造住房和设计市场创造更多对熟练工作的需求。

Construction practitioners, researchers, and other stakeholders of construction in Canada are becoming increasingly cognizant of the need for a transformation in home building methods. The automotive sector has enjoyed the benefits of automated design and manufacturing for years, and now the time has come, with the skilled labour shortage and high demand for affordable housing, to propel that same automation toward the home building industry. There has been an increasing demand for extensions (i.e., add-ons enabled by Application Programming Interface) to existing design and drafting products in order to address the specific needs of the modular building industry and a cloud-based information sharing environment intended for direct collaboration among multiple project stakeholders (e.g., consumers and building designers). Therefore, the aim of this research is to develop cloud-based building information modelling (BIM) tools for collaborative editing and sharing of a model by users of widely different skill sets, from consumer to panelized home designer, estimator, and production manager. In order to achieve the proposed objective, three activities will be conducted: (1) migration of the collaborating company's (Cadsoft Corporation's) code base to a service-oriented architecture; (2) real-time collaborative model editing; and (3) automated manufacturing-centric BIM. It can be expected that through this project the industry partner can benefit by redefining their current BIM software, and the building industry can improve its productivity and efficiency of design and drafting, decision making, and production. The proposed research will form a BIM system that is suitable to the modularization/panelization construction industry, and which optimizes the material usage of projects and reduces carbon chemical emissions incurred during construction. These combined efforts will increase the workforce in the housing industry, will lead to wider adoption of Cadsoft's Envisioneer software by home builders, and will create increased demand for skilled jobs in the manufactured housing and design markets.
