'"Tier2Tier": A collaboration interface between construction main contractors and their supply chain specialist sub-contractors

人们已经认识到，如果没有主承包商供应链的合作，BIM的好处将无法实现：二级及以上。这方面存在重大障碍，如果不克服这些障碍，2级BIM的CDE是不可能实现的。作为回应，Tier 2 Tier是一个基于SaaS的解决方案，将为Tier 2专家提供一个独立的，可控的，双向的，基于云的微型协作门户，允许从投标到最终账户的双向传输验证信息。设想的服务支持BSI B/555路线图的目标，通过促进受控输入、投标交换、合同管理、自动支付交易、变更管理和COBie数据传输，同时最大限度地减少用户费用。这个合作项目解决了项目团队达到2级BIM成熟度所需的CDE中更广泛的项目供应链参与的障碍。这将通过重新审查招标、发票、变更管理和支付等企业对企业流程，以及使用新的“大数据”和社交图方法来管理多个BIM项目来实现。

It has been recognised that the benefits of BIM will not be realised without the collaboration of the main contractor’s supply chain: Tier 2 and beyond. There are significant barriers to this and it is unlikely that the CDE for Level 2 BIM is achievable without overcoming them. In response, Tier2Tier is a SaaS-based solution that will provide the Tier 2 specialist with an independent, controlled, bi-directional, cloud-based micro collaboration portal, allowing the 2-way transfer of validated information from tender through to final account. The envisaged service supports the goals of BSI B/555 Roadmap by facilitating controlled inputs, tender exchange, contract administration, automated payment transactions, change management, and COBie data transfer; all whilst minimising user expense. This collaborative project addresses the obstacles to participation of the wider project supply chain in the CDEs required for project teams to attain Level 2 BIM Maturity. This will be achieved by the re-examination of the business-to-business processes of tendering, invoicing, change management and payment, as well as using new “Big Data” and Social-graph approaches to manage multiple BIM projects.
