BIM Software for Construction Email - john.adams@viewpoint.com Twitter - @Johnad25 Web & www.4projects.com www.viewpoint.com When choosing BIM Software….. The BIM dimensions 7D Lifecycle management 8D BIM saves kittens from trees 9D BIM for world peace… What are BIM uses? “a method of applying Building Information Modeling during a facility’s lifecycle to achieve one or more specific objectives.” PENN State University BIM Execution Planning Guide What are BIM uses? Plain Language Questions? A set of plain language questions that a client intend to answer at each stage of a construction project. Key decisions such as whether to proceed to the next work stage or not will be made based upon the answers to these questions Once you have your uses and your questions … Capture them in an EIR The Employer’s Information Requirements (EIR) form part of the appointment and tender documents on a BIM Project. The EIR define which models need to be produced at each project stage – together with the required level of detail and definition. These models can be key deliverables in the ‘Information Exchanges’ – contributing to effective decision making at key stages of the project. So your tender has an EIR based on your BIM uses… The Main Contractors will respond with a BIM Execution Plan There are Pre-Contract and Post-Contract versions of the BIM Execution Plan. Where possible a standard template should be used to simplify tender scrutiny. The CPIx have excellent templates for this reason You’ve asked for your Information… Your chosen contractor has a plan to deliver it… So how are you going to use it? Says What are Open BIM Standards? = Common Data Common Data Environments Open BIM is a universal approach to the collaborative design, realization and operation of buildings based on open standards and workflows. 16 Regional Chapters Including…. IFD - International Framework for Dictionaries IDM - Information Delivery Manual MVD - Model View Definitions bSDD - BuildingSMART Data Dictionary BCF – BIM Collaboration Format (Candidate) IFC Industry Foundation Classes What is IFC? IFC definition…. a common data schema that makes it possible to hold and exchange data between different proprietary software applications. The data schema comprises information covering the many disciplines that contribute to a building throughout its lifecycle: from conception, through design, construction and operation to refurbishment or demolition IFC misconceptions…. “IFC loses important data…” “It’s Impossible to get a good IFC out of some BIM authoring software…” “I exported and re-imported an IFC and there were missing elements…” IFC reality…. IFC doesn’t yet replace your native design files… But it enables you effectively to share your designs. Image by buildingSMART Canada So client on you projects are ready to accept IFC models right? …Thought not, very few people are …Luckily there’s COBie! What is COBie? COBie… … is a Model View Definition (MVD) as defined by buildingSMART … is a subset of IFC with some additional data … simplifies the work required to capture and record project handover data. … captures data as it is created during design, construction, and commissioning … does not require endless spreadsheet editing … is a UK Government requirement by 1st 2016 Why COBie? Once a validated COBie dataset has been delivered to the building operator matching the built asset; all operations and maintenance data can be interrogated from a single place. Meaning this type of information about built assets… …Instead of this B 555 roadmap - The Mandate taking shape The BS/PAS 1192 series of standards are the most important releases to date. PAS 1192:2 Concerns the Level 2 Delivery of projects. PAS1192:2 What’s it all about? characters What is BIM Data? Documentation Information for use in the briefing, design, construction, operation, maintenance or decommissioning of a construction project, including but not limited to correspondence, drawings, schedules, specifications, calculations, spreadsheets NOTE Documents must either be immutable or incorporate a means of controlling changes. What is BIM Data? Non-graphical data data conveyed using alphanumeric characters What is BIM Data? Graphical Model data conveyed using shape and arrangement in space … ALL of this data is to be delivered to and shared through a Common Data Environment approach. It is a ‘Fundamental Principle for Level 2 information modelling’ = Common Data Environment Common Data Environment (CDE) – PAS1192:2 ‘Single source of information for any given project, used to collect, manage and disseminate all relevant approved project documents for multi-disciplinary teams in a managed process.’ ‘NOTE, A CDE may use a project server, an extranet, a file-based retrieval system or other suitable toolset’ What are the issues? Documents and drawing are easy to share – 4Projects have been facilitating effect collaboration around these for years But getting the most out of sharing Building Information Models presents a new challenge….. How does everybody see the model and it’s data? Ownership the federated information? Can unfinished worked be shared to assist the design process? How is the Information exchange data compiled and validated? PAS 1192:2 and 4Projects Workflows are here to help So that’s the theory…. What about the practice? Single Design Models SDMs Master Design Model MDMs But doesn’t this only apply to buildings? The VSU model encompasses the entire project and incorporates 18 discrete design disciplines, showing how the entire project fits together. [The] Federated project supply chain [produced] a co-ordinated information model To maximise interoperability between disciplines, LU’s preferred collaboration software, [ ]was used wherever practicable. When this was not possible, the transition of electronic information between the different platforms being used was assisted by tailoring software configurations and using ‘platform agnostic’ models. Translating the B555 Roadmap into the CDE. EIR WIP • Employers Information Requirements • BIM Execution Plan • Single Design Models • Master Design Models BEP Shared Plan of Works Stage 1-6 Published Archived Plan of Works Stage 7-n How does this fit with contracts, appointments, briefs etc… Confirmation from the major contract providers has been received that on minor clause amendments are required to incorporate BIM Protocol to sit above the contract. The clause changes must be cascaded throughout the project appointment for successful collaboration. The PAS1192:2 Level 2 Fundamentals include the provision Employers Information Requirements, from Client to Supplier and a BIM Execution plan in return from Supplier to Client.
