5D (Cost):

Drawing on the components of the information model being able to extract accurate cost information is what's at the heart of 5D BIM.

Considerations might include capital costs (the costs of purchasing and installing a component), its associated running costs and the cost of renewal/replacement down the line. These calculations can be made on the basis of the data and associated information linked to particular components within the graphical model. This information allows cost managers to easily extrapolate the quantities of a given component on a project, applying rates to those quantities, thereby reaching an overall cost for the development.

The benefits of a costing approach linked to a model include the ability to easily see costs in 3D form, get notifications when changes are made, and the automatic counting of components/systems attached to a project. However, it's not just cost managers who stand to benefit from considering cost as part of your BIM process. Assuming the presence of 4D programme data and a clear understanding of the value of a contract, you can easily track predicted and actual spend over the course of a project. This allows for regular cost reporting and budgeting to ensure efficiencies are realised and the project itself stays within budget tolerances.

The accuracy of any cost calculations is, of course, reliant on the data produced by multiple teams and shared within the Common Data Environment. If that information is inaccurate, so too will be any calculations that rely upon it. In this respect using BIM to consider cost is no different to more traditional ways of working. It is for this reason that quantity surveyors and estimators still have an important role to play, not only in checking the accuracy of information but also in helping to interpret and fill information 'gaps'. Many elements of a project will still be modelled in 2D or not at all. There's also likely to be differences between models in how things are classified and the cost manager will need to clarify and understand the commonality between what at first feel like disparate things.

An information model is likely to contain three types of quantity. Quantities based on actual model components (with visible details) which you can explore through the model are the most obvious. Quantities may also be derived from model components (such as mouldings around windows) that aren't always visible. The third kind of quantity is non-modelled quantities (these include temporary works, construction joints etc.). Unless the construction phase is modelled then the design model will show, graphically, design quantities but not the construction quantities. A cost manager is likely to be skilled in picking up the quantities that aren't solely based on model components.

One of the advantages of extrapolating cost from the information model is the fact that the data can be queried at any time during a project and the information that feeds cost reports is regularly updated. This 'living' cost plan helps teams design to budget and because cost managers are engaged from the start of a project this allows for faster, more accurate reporting of costs at the early stages of a project. Compare this to a traditional approach where a cost manager's report may be updated a few times during the early stages of a project with completed designs only fully costed at the end of the project team's design process.

The cost manager may have to get used to working earlier and more iteratively than in a traditional process but has just as important a role to play in overall project delivery.

At "Bana Yar Mehraz Iranian" , we assist engineers and contractors to integrate cost estimates with BIM along with time and schedule data in IFC (open standard) format to be used in any BIM visualizing or authoring system (Revit, Navisworks, BDS, Archicad, Tekla etc).
Our BIM 5D solutions help you keep track of the cost incurred at every stage of construction and deliver substantial benefits in terms of cost estimation to several large scale construction projects.

Why ?

Predicting the most realistic figure at different - or any given stage in a project is an important aspect, as it helps evaluate the design and construction process based on budgeting constraints.
Conventional estimating techniques that rely on two-dimensional drawing measurements have substantial potential for ambiguity, inefficiency, and error. A three-dimensional project model removes the ambiguity and potential inconsistencies in project quantity estimations.
The fifth dimension (5D) is cost, which is brought into the virtual building life cycle.

We are proud of the service that we provide for our customers

Our BIM experts assist quantity surveyors, contractors and planning engineers for cost estimation with 5D BIM services.

When building construction projects see rising complexity, controlling expenditure and material waste is critical for construction companies. Estimating overall project costs and eliminating substantial ambiguity is the way for efficient construction works.

We deliver accurate cost estimation along with quantity takeoffs using virtual as-built intelligent 3D models for building construction projects having multiple complexities. We partner with large construction companies, architects, engineers and contractors to help them evaluate near accurate costs for bidding, winning tender approvals, order quantity for prefabrication and construction billing solutions through VDC solutions.

Our in-house teams of civil engineers along with teams experienced in BIM Consulting and implementation aids cost estimation through software tool help contractors predict the material requirements planning, and evaluate costs of entire project including labor costs. We develop highly interactive and virtually intelligent BIM models for execution of construction project plans, assembly and installation of components.

We enable our clients practice lean construction that incurs minimum waste and least possible costs. Our 5D BIM modeling offerings focus on calculating costs through as built BIM models in Revit and excel sheets for quantity calculations. We focus on implementing costs models by eliminating design and workflow clashes to ensure that there are minimum costs correction once the tenders are laid.
