Job Description

Contributing to the strategy and implementation of Building Information Modelling (BIM) in support of Nuclear and Non-Nuclear Safety related facilities for the Major Infrastructure Projects programme.

Providing BIM support within the core engineering team.  Providing support and leadership to projects and ensuring consistency in the way MIP and the wider DRDL delivers BIM.  The Principal BIM & Digital Engineer is accountable to the BIM & Digital Engineer Lead.  The Principal BIM & Digital Engineer is a deputy role and will support the BIM lead.

Rôle and Responsibilities

  • Ensuring the Business Unit BIM Standards are applied to the Project, and following the Delivery Team BIM Execution Plan (BEP). Leading and driving BIM on the project.
  • Providing Building Information Modelling (BIM) authoring support to the project, using the appropriate technology as prescribes in the Delivery Team BEP. Model authoring – ability to author BIM models to support BIM maturity and supporting activities within design packages as defined in the project Responsibility Matrix.
  • Supporting the Information Exchanges within the CDE solution, and managing the folder structure and repositories for project data.
  • Producing high quality – families, objects that are parametric based and suitable for the native authoring platforms. Supporting model and content management activities to support digital re-use objectives. Contributing and ensuring model content is appropriately developed and supporting the configuration management principals.
  • Owning and developing the project delivery team BEP.
  • Driving and ensuring the BIM Production Methods and Procedures (PMP) workflows are appropriate to the project.
  • Ensuring that model ‘level of information need’ is aligned with the project responsibility matrix and is appropriate to the project stage. Developing the Responsibility Matrix for the project.
  • Ensuring the project team meets the BIM level 2 standards as outline in BS1192:4 Collaborative production of information Part 4: Fulfilling employer’s information exchange requirements using COBie – Code of practice.                                                                                                           
  • Use the COBie Toolkit for delivering COBie data rich models and; Use the Uniclass Classification Tool for Uniclass Classifications.
  • Understanding on NBS – and applying specification codes to the drawing output sheets, and model parameters/attributes.
  • Ensuring COBie outputs are aligned with the COBie demand matrix and AIR.
  • Work with the Digital Library coordinator to ensure modelling objects reside in the project, but also within the wider MIP Digital Library. Ensuring appropriate governance and checking of library content.
  • Using the H&S beacons in BIM and ensuring, these are used, referenced and exported as necessary. This would be aligned with the H&S section contained within the project BEP. Ensuring SHEF and Risk Register are aligned with model content. Supporting H&S output data from models and actively supporting migration of risk in conjunction with the wider design and construction team.
  • Producing high quality BIM models and associated output drawings applicable to the works package. Technical aspects of outputs will be supported and under the direction of the project design engineers and design managers were appropriate.
  • Following the CDE process and use of the WIP, SHARED and PUBLISHED states of the CDE solution.
  • Owning model coordination of the design solution and ensuring clash issues are resolved in a timely manner and working with the wider design teams.
  • Reporting on any model issues that may have an impact of design maturity, model build or design coordination and interfacing matters.
  • Working with the wider design team and BIM team to ensure BIM delivery is successful as is the project.
  • Defining the Volume strategy for the project and ensuring Building Information Models are developed in line with the project volume strategy. Ensuring that models have clear boundaries of ownership and ensuring model content is not duplicated across multiple models.
  • Supporting and preparing for 4D and 5D aspects on the projects, this would relate to preparation of models for 4D purposes, and the issue and working with the project control teams for 5D purposes and the export of BIM models for the estimating community.
  • Validating models using the model validation checklist and checking tools, to ensure models are appropriately built, categorised and fit for use.
  • Validating models – for completeness, in both; graphical and non-graphical data. Ensuring model are fit for purpose to migrate into a 6D Hand-Over and integrating into the Asset Information Model. Carrying out advance model checking using tools such as Solibri.
  • Reporting to the BIM leadership on implementation and health status of BIM delivery. Supporting training and upskilling of the wider team in support of BIM delivery.
  • Provide 4D capability by federating 4D Models with models delivered into the shared area of the CDE solution. Working with the project programmer’s and identifying key activity and linking model content with schedules.
  • Supporting and updating the BIM documentation for the project and contributing to the master matrix and Business Unit BIM standards as directed by the BIM leadership.
