Building Information Modelling (BIM)

  • At Aquenta, we believe that Building Information Modelling (BIM) is key to unlocking value in project delivery and asset management.  We recognise that not all projects have the same objectives or
    goals and similarly not all clients have the same requirements from BIM. Client requirements may vary from financial by providing cost accuracy and efficiency, reduced construction duration by providing certainty through virtual simulations, or management of an Asset Information Model (AIM) though re-use and integration of information back into the model.

    As a leading provider of Integrated Project Services, Aquenta is well placed to leverage the experience and knowledge from our Project Management, Planning and Controls, Cost Management and Asset and Facilities Management Service Streams. The availability and collaboration of these Service Streams means that Aquenta can offer a complete and rounded BIM service.

    OUR BIM SERVICES

    BIM Implementation and Management

    • Clearly identifying and consulting with the client on their expectations of BIM and development of a strategy to deliver these requirements.
    • Establishing best practice BIM protocols and procedures at project inception to ensure a successful BIM project delivery.
    • Clearly defining and structuring what is required in terms of BIM deliverables from project team members and proposed contractors at all stages of the BIM process.
    • Providing advice on the most suitable procurement method and preparing associated documentation.

    High level advantages of BIM implementation on a project include:

    • Improved speed of delivery.
    • Reduced design and documentation errors.
    • Reduced re-work and shorter work flows to produce documentation.
    • Improved coordination of project design and project outcomes.
    • Improved collaboration between project teams.
    • Improved client and end user engagement and understanding.
    • Greater certainty with regards to time and cost of project.
    • Reduced risks through early identification and mitigation.

    Virtual Construction Simulation – 4D and 5D Simulations

    • Integration of proposed construction schedule into 3D model to produce a 4D construction simulation of the works. This provides a visual representation of the construction works, this can be displayed per level, per area or even per element.
    • Integration of construction costs into 3D model to produce a 5D model simulation. This provides a cash flow forecast based on the visual representation of the works, it also provides an expended to date total at any point in time.

    Advantages of Virtual Construction Simulations include:

    • Providing client and project team with a graphical representation of the construction process, this allows for  improved communication and understanding and allows for concise decisions to be made earlier in the design process.
    • Providing the client or end user with an improved understanding of the design intent by visualising the proposed internal layouts and internal design.
    • Challenging the proposed construction schedule by identifying errors or clashes before constructing on site, this in turn reduces risk of potential reworks and delays on site and therefore increases time certainty and performance certainty.
    • Graphically tracking progress on site and identifying specific areas where progress has been delayed from planned completion dates. This allows both Project Managers and Contractors to manage and control risks on site.

    5D Model Quantification

    • Production of estimates, Bills of Quantities or Builders Quantities by harvesting dimensions from 3D models.
    • Automated quantification which allows for review of multiple proposed designs at project inception.

    Advantages of 5D Model Quantification include:

    • Faster delivery of estimates and tender pricing schedules, the shorter duration results in an earlier start date for construction.
    • Multiple ‘optioneering’ of cost estimates provides the client and design team with the opportunity to make both budget and design decisions at project inception.
    • More accurate cost estimates and tender documentation reduces costs risks by decreasing errors due to omissions.
    • Rapid quantity trending by comparison of revised models with baseline model.
    • Non-subjective program claim assessment by progressively statusing objects in model when completed.
    • The ability to link costs back to the model to produce a 5D simulation and complete cost loaded model for facility management purposes.

    Asset Management

    • Appending information to an existing Asset Information Model (AIM).
    • Linking geometry from an AIM to an external data base.
    • Structuring link between AIM and FM package software.

    Advantages of Asset Management include:

    • Timely identification of asset items which require maintenance or replacement.
    • Identification of physical location of the particular asset items and access restrictions or requirements to carry out scheduled maintenance or replacement.
    • On site coordination between proposed new works and existing AIM, thereby reducing risk of unforseen clashes.
    • Available information to plan maintenance or replacement including maintenance/ replacement items required and previous cost to supply and install asset items.
