Project Overview
Initially, the Developer (Wanda) had no requirement for BIM or intention to develop any BIM processes or workflows. Therefore, the project was originally tendered to Multiplex (our Client) using traditional 2D pdf plans and elevations level of information. The contract requirements also placed a novation of the original design team but unfortunately some organisations not being able to demonstrate suitable Multiplex’s supply chain capability requirements nor did they include a BIM protocol. However, with extensive levels of BIM experience, ONE was able to simply demonstrate our capabilities covering all disciplines required by the Client via their online SCCS tool.
Multiplex appointed their own in-house Information Manager to the scheme, who developed an initial Information Management Manual similar to a Pre-Contract BIM Execution Plan, which was used by ONE in the early stages of the project.
As the project commenced the modelling stage, a formal project BIM Execution Plan was developed and was the document used to manage the projects’ BIM requirements and used for all of ONE’s information models.
The modelling and BIM tools used for the project were Revit 2016 and Navisworks Manage 2016 in accordance with the BEP native file formats requested. The native file formats required for the issue of each model was NWD 2016 (Navisworks) and IFC (IFC 2X3 Co-ordination View 2.0).
The Level of Detail was specified as LOD300 for intended replacement by each suppliers more advanced level of detail objects and assemblies to populate the Project Information Model later in the project. The client also had a specific requirement for proposals to provide clarity on the co-ordination between the design disciplines and ensure the spatial zoning and clash avoidance was satisfied. During the development process, ONE identified an extensive number of clashes which were listed for design team resolution. ONE also offered some general solution recommendations although resolution/Interface Management was the responsibility of the Design Team.
Multiplex used the data rich models for a variety of different purposes including 4D construction planning and virtual modelling, 5D cost analysis and subcontractor tendering purposes.
The projects selected CDE was Aconex Limited extranet product, provided and managed by Multiplex.
Uniclass 2015 is used for the classification system for the project where it is proposed to utilise the “SS-Systems” code table, using “Group” “Sub-Group” and “Section” elements for intended 5D cost programming and supplier interaction and appointments. In addition, the RICS NRM codes are also required as a dataset information input.
At present, the requirements for Asset Tagging is still in development following recommendations made by ONE concerning dataset information requirements. Therefore, the current strategy is for asset information to be provided by others (supplier subcontractors) within an excel spreadsheet to allow ONE to populate the appropriate information within a shared parameter. Full COBie levels of information are deemed excessive by the Client and unnecessary for their purposes and so has not been incorporated into this project.

One Nine Elms is an excellent project to be involved with and really demonstrates the benefits of BIM that we can offer to our clients.
