THIESS BUILDINGPRESENTATION TO AMCA BIM-MEPAUSFORUM 27JULY 2011
Thiess overview • Founded in Queensland in 1934 • Australia’s largest construction, mining and services company • Turnover $6.8B • Work in hand: $22.2B • More than 17,500 employees and subcontractors across more than 200 projects • Operations in Australia, NZ, Indonesia, India and UAE • Owned by Leighton Holdings Ltd Playing a unique role in Australia’s construction history
capabilities We maintain a strong portfolio with significant diversity across the construction, mining and services sectors. Our experience covers: • Civil • Mining • Services • Industrial Projects • Tunnelling • Rail • Building • Facilities Management
Thiess building • A professional Design Management & Construction Management team • We don’t design - we manage design with/on behalf of our clients

BIM FOR ALL NEW PROJECTS • Most importantly, through the experience on the ARK, Thiess were convinced BIM is the future. • All parties involved in this exercise walked away with better understanding of the potential of BIM, but also of the process and skills required to effectively use it. • Since the completion of the ARK, Thiess Building has committed to a strategy that all future building projects will be delivered through a BIM process. • BIM capability is increasingly becoming an important criterion when we select consultants and D&C subcontractors.

BIM IS A PROCESS BIM is a PROCESS, combined and integrated with supporting TECHNOLOGIES. A correctly assembled BIM is a reliable, digital, three dimensional, “virtual” representation of the project, for use by the client, contractor and project team in: • brief validation, • design decision-making, • cost estimates, • construction document production, • construction scheduling and planning, • performance predictions, • building commissioning, • building management and maintenance. A single “BIM” system will not currently support all of the above, and likely will not for some time.
BIM challenge A REAL issue is that many stakeholders are gaining no benefit from BIM due to the lack of understanding of “basic” BIM PROCESSES. BIM starts with, and its success relies upon, implementing; • strategy and process, • standardised terms/definitions/information, • and a technology backbone to enable • cost effective implementation, scalability, • information reuse, and • ongoing decision support.
Bim execution plans What we need and what we get is too often dependant on the background of who authors it. So we can end up with: • Architect/Principal Consultant as BIM Manager • Head Contractor as BIM Manager • Independent Consultant BIM Manager What we need is: • BIM Execution Plans which spell out Who,What, Why, When, How. • Especially explain who will use the data at the various project stages and therefore how it needs to be formatted. • Deliverables and responsibilities clearly defined. • Plan the BIM process to support decision making milestones. The AIA Building Information Protocol is not a BIM Plan.
DATA USERS ARE often forgotten The key users of the BIM data need to be involved in the scoping of the BIM process: • The Head Contractor • The Cost Planner • The Client/Owner?????? • Biggest potential of BIM for Head Contractors is day to day use on site. • Site staff aren’t generally computer comfortable. • Solutions must be quick to access and quick to understand. • Systems and processes implemented at design commencement determine success of model use on site. Remember the Contractor is typically a data user not a data creator.
Naming conventions Establish consistent naming conventions across project teams. • In many cases project teams start their modeling work in isolation. • First Federated Model is not created until all team members are well entrenched in their practices. • The “entrenchment” oftentimes is not so much a technical issue but an issue of habits that the individual team members have developed. • Creating consistent naming conventions for model elements, sub-elements and attributes can easily be done at the beginning of a project and will create efficiencies every time models are federated, jointly reviewed or leveraged for downstream processes (e.g. quantity take off, scheduling). We find it the single most important convention for usability of the models
Level parameters Every component of a building is built on a particular level • Often due to model file size and programme, design reviews, clash detection, quantity extraction will be done per level. • We also use the model and parts of the model to produce Work Method Statements and Workpacks. • Allocate a level parameter to every model element. • In some software such as Revit MEP it can be difficult to allocate a level parameter to some system families but can usually be fixed with a shared level parameter. • Supply search sets for your systems with your models.
One model Export/publish each element just once at each issue • This is not about a single integrated model vs a federated model. • It’s about the data users, i.e. the Contractor, the QS, the Client receiving one copy of each model element at each issue when it matters. • Monitor and manage your own models to eliminate duplications of elements. • Manage your federated models to eliminate duplications of elements between disciplines.
Asset data Populate your source models, not the Federated Models. • The model review tools (tools for creating Federated Models such as Autodesk Navisworks, Solibri, Bentley Navigator or Tekla Project Manager) that are available today offer many ways of entering data and information into models. • The unintended consequence of the practice of entering information into model review tools is that project team may end up with conflicting or missing data. • Of course there are many situations where it is impractical or impossible to know and populate all the information that may be needed in the source models.
DELIVERABLES BIM is not just about the modelling software and families development. It’s a data rich computer model that needs to be transmitted between and edited on several other programmes. We often need; • Revit .rvt files for record, for some subcontractors, for as-builts, • Navisworks .nwc files for collaboration, co-ordination and timelining, • Autocad 3D .dwg files for some subcontractors • .ifc files for some subcontractors and sometimes for other consultants • Autocad 2D .dwg files for use with CostX and some subcontractors, for as-builts • Autocad .dwf(x) model files for use with CostX • .pdf files - vectored & layered if for CostXor rastered if only for record This requires adherence to well structured export protocols
Bim enabled ipd BIM is an integrated project delivery process. • It is only truly successful with collaboration between all stakeholders. • A true IPD process includes sharing risk and reward? • Understanding and contributing to a collaborative process is all important. • As BIM develops we will team with those with experience. • With IPD we will team with those we trust. If you have well developed, documented, industry aligned and collaborative BIM processes then perhaps trust is more likely.
BIM-MEPAUS Advancement of BIM Collaboration requires the protocols and processes to be anticipated at the commencement of design. To achieve this we need: • Industry standards for BIM that can be simply and quickly referenced, adapted and implemented by the Client, the Principal Consultant or the Head Contractor. • Together with workflows that enable outcomes to be delivered efficiently and repetitively in the marketplace. • All formalised in BIM Execution Plans with an industry supported format. Thiess believe, industry initiatives such as BIM-MEPAUStogether with the Natspec National BIM Guide project will provide the basic templates to: • align understanding, • remove confusion, • maximise effort, • promote trust and • deliver BIM enabled Integrated Project Delivery.
