Fred Mills, Co-Founder of The B1M, speaks on 4D BIM

Fred Mills, Co-Founder of The B1M, briefly throws light on 4D BIM and how it impacts BIM projects through this exclusive youtube BIM video.

In simple terms, BIM is defined as the method of producing information models or data sets created with graphical and non-graphical information in a shared digital space called Common Data Environment (CDE). The information is developed in richness with the advancement of project phase till the whole data set is delivered to the Client and/or end user once the project is finished.

Once an information model is formed, scheduling data can be included to various components, providing perfect programme information and facilitating successive visuals concerning progression of project. This procedure is termed as 4D BIM.

Combining cost data with the purpose of supporting cost planning and creating estimates is identified as 5D BIM (http://www.theb1m.com/video/what-is-5...), whereas the addition of information to sustain facilities management and operation is titled 6D BIM (http://www.theb1m.com/video/what-is-6...).

4D BIM consists of time-related information that can be combined to several components concerning an information model. To deal with any particular element or work area, that could comprise details on its lead-time, construction and installation period, curing and drying allowances, sequencing or its interdependencies with other areas. With this detailed data, Planners will be able to instantly produce perfect programmes for projects, on the basis of one trustworthy source of federated information. The particular activities and items inside those programmes can be transparently associated with their graphical representations.

The addition of time-related attribute data also facilitates 3D visuals of a project’s growth being developed, demonstrating how it will be built up and how both the structure and surrounding site will be visible at all stages. By acquiring visual information instantly, the project team members can efficiently prototype assets in a virtual environment initially and offer quick feedback regarding modifications of design or methodology to their colleagues.

Thus the project delivery process will be accelerated as the approach will facilitate to disavow last minute on-site design co-ordination and revise as well as reduce waste from the delivery process in due course. The cost base for project teams and overall delivery cost for clients will be minimized significantly.

4D BIM is also a robust tool for exposure the influence of built assets with local Stakeholders throughout delivery and when completed. Each one will get clear idea and realize a apparent impression concerning how the asset will become visible, instead of having to visualize that from plans or Gantt charts.

4D can be applied at any phase of a project, and it can put in a lot of value and impact at the front end while evaluating the viability of schemes. It’s also functional all through tendering while comprehending a project within short span of time or illustrate and develop confidence around your technique as part of the selection process.

Importance of 3D Constructible Models for creating & setting up MEP design

Recently several new working systems like BIM 3D modeling, 4D BIM for construction scheduling, implementation of constructible models for cost estimation, sustainably, lean construction as well as 7D BIM for facility management, have emerged out for AEC industries which boost up the digital progressions.

BIM mainly focuses on three sectors like Architectural, structural and MEP and the professionals associated with these segments can get unlimited advantages with BIM application.

As compared to architectural and structural field, MEP is considered more complicated and is vital for successful completion of any project. MEP field comprises several professionals which range from MEP consultants, fabricators, MEP installation and maintenance experts and mechanical – electrical-plumbing- fire safety - trade specific sub-contractors.

MEP design and installation experts always look for technologically developed processes to shift from decade old 2D MEP drafting & drawing to superiorly coordinated constructible models.

With constructible models for MEP, information based models can be applied in noteworthy and large scale projects over the globe to synchronize, design and set up mechanical, electrical and plumbing systems in a well organized way.

In order to successfully complete a construction project, there should not be any conflict with the MEP design delivered to MEP contractors. 3D BIM constructible models are vital here. MEP BIM can be demonstrated in the identical way it will be shown in post construction in a 3D virtual environment. With the powerful visualization capability, all types of conflicts can be detected & resolved efficiently.

The MEP designer and the contractor can mutually work together successfully to evaluate the MEP systems in better detail and make use of both designer and contractor level modifications like rerouting pipe work, resizing ducts, finalizing bolt locations, and executing design modifications for smooth fabrication and fitting efficiency in the initial design phase prior to completion of project in reality.

This MEP BIM coordination will certainly resolve all the issues and build up a well-synchronized MEP design. It will minimize the necessities for project based improvisation & reconstruction and also liabilities, as well as effectuate significant cost and time efficiency to the project.

Besides, encrypting 3D model with perfect dimensional data and for conflict resolution and mitigation, the objects are also encrypted with diversified aspects which range from energy performance data, component materials and finishes and cost information.

So, the constructible 3D models become essential in design and setting up sustainable MEP system. It also facilitates precise cost estimation that leads to minimizing the possibilities for budget failure and accomplishment of incomplete projects.

How project stakeholders can apply BIM in their work process

BIM can be applied as a work process and means of communicating with one another in the project delivery method to illustrate the end product (the model itself).

BIM generated a virtual process that covers all characteristics, disciplines, and systems of a building inside a single, virtual model facilitating all project stakeholders to work together more precisely and competently. Thus BIM creates a collaborative design process.

After the creation of the model, team members are continuously clarifying and regulating their portions in accordance with owner preferences, system's adaptability and design intention to maintain the accuracy of the model before the commencement of the actual project. If any modification is made by the project team members, it affects the entire model, creating continuous communication

After that the model itself is utilized to exchange information for design concepts to the owner. The model is also applied for estimating materials take-off for cost estimation and for conflict detection to electronically verify the proper designing of the building system. BIM can trim downs change orders by making changes electronically rather than on the job site which can get a huge saving in time and money for project schedule and budget.

Design information from all disciplines as for example from architectural designs and specifications to structural and mechanical systems information such as HVAC Ducting, piping and structural slabs, columns and shear walls are provided in the BIM database. The database includes and combines all elements of a finished building to one main database of linked project information. If any, the BIM database would mechanically rearrange all connected elements implanted in the interrelated database to communicate with any changes occurred with one element of the design.  A BIM database can surpass it’s 3D modeling capability and perform for 4-D (construction scheduling) and even 5-D (cost flow analysis). The database could significantly lessen waste in construction as well as time delays raised  by RFIs and change orders. 

BIM has also shifted time spent in various phases of design, placing more emphasis in the initial design phases and less in the construction documentation phase. Whereas with traditional CAD processes the bulk of the time was spent preparing construction documents, BIM requires more time up front, fully develop the design and model. When a BIM project goes into construction documentation, all that’s left to do is decide where to cut sections through the building and print the documents.

BIM can flawlessly gather in and incorporate the input and flow of information among design and construction professionals to make the entire process more efficient and reduce delays and cost overruns.

BIM can characterize a design as objects in the form of indistinct and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), which contains their geometry, relations and attributes. The geometry possibly will be 2D or 3D. The objects may be conceptual and are constructed detailed. A building model is described by compiling together these objects. If an object is modified or moved, BIM tool then starts to dig out diverse views from a building model for drawing production and other application. These diverse views are mechanically constant i.e. the objects are all of a constant size, location, specification. Drawing uniformity reduces many inaccuracies as each object instance is defined only once.

Modern BIM technology identifies objects parametrically. Here the objects are identified as parameters and relations to other objects, in order that if a correlated object is modified, this one will also. Parametric objects mechanically reconstruct themselves in relation to the rules implanted in them. The rules are uncomplicated, involving a window to be wholly within a wall, and moving the window to the wall, or complex defining size ranges, and detailing, such as the physical connection between a steel beam and column.
