Building Information Modeling is a process of developing detailed 3D Model loaded with graphical, design representations and data rich models which can be used for varied purposes during construction and before construction. Facility management is one of the many areas where BIM can be utilized efficiently. Ever since BIM has come into existence it is on a roll. Building information Modeling has come a long way since its modest beginning and has made project planning, Phasing and design validation with a better approach. 

Let us talk about how BIM is overall beneficial in facility management. BIM Modeling Services overall is a process which talks about design, development, collaboration, validation and construction all through a single 3D Model. This 3D model acts as a base for all the pre-construction and post construction processes. Facility Management is one of the areas which can benefit in a very great manner. Every user can perceive BIM in a way that is beneficial to them. BIM for an Architect is a way to present the design graphically, BIM for an Engineer is all about calculation and compliance, BIM for a facility manager is optimum utilization of space, maintenance of accurate building data, managing an infrastructure with relevant asset tagging etc. is extremely important.

Advantage of BIM cannot be broadly gauged or defined, it has to be considered based on the end user and the purpose of BIM. Before talking about how BIM is beneficial in facility management, we shall briefly talk about how others benefit from BIM 

BIM for Architects:  Building Information Modeling is used by Architects for designing and design validation. Architects can understand and present their Architectural design in the most splendid manner than it can ever be. By using BIM Modeling, Architects can model Facades, complex roofs, site, interior flooring, curtain walls, ceilings, walls, furniture etc. These presentations can then be reviewed and modified according to requirements of the builders or end client for that matter. Developing a conceptual Revit Model, rendering these models with all possible entities can give a very clear idea of how the building will look like post construction. Design alternatives can be developed using Revit Design Option feature in the software. Initial conceptual Models created by Architects can assist Engineers, Structural Designers etc. in interpreting and conducting further studies or research on how their designs need to be contemplated.  Architects can work on many techniques of modeling such as 3D Presentation Models, LOD 300 to 500 models etc. providing several details in a single format. The same model further can be utilized by Facility managers with complete information that can help managing the overall building efficiently in terms of quantity of assets that needs to be manufactured, stock and quantity maintenance, planning space based on how the building will sustain post complete occupancy, parking’s etc. 

BIM for Facility Managers: Building Information Modeling for facility managers is a lot more complicated than the BIM Models developed by Architects. For developing a BIM Model that can be used for facility management, there are many details that needs to be considered. These large chunks of information include the following

– Asset Tagging: It is very important to tag the overall components, furniture, MEP equipment or any other part within the model with Serial number, Manufacturing code, material specification, number of assets of similar kind etc. imbibed in the families or components itself. There is a need to put in large volume and very specific information in the model. 

– Space planning: Space planning is one major features of the BIM model for facility management. Architects and Engineers need to develop the model keeping in mind that the space planning within a building is optimum and is being utilized to the fullest without being cringy. There needs to be enough doorway, ventilation, proper lighting, fire exits etc. such allowances should be given in the buildings. The model should not be loaded with unwanted elements or unnecessary data that cause a “Model Bloat” .The model that suffers from this phenomenon will be very heavy and will have unwarranted data that can actually deteriorate the BIM model potential. There can be severe issues with the speed of execution, analysis and the results many be inaccurate. Since this is a digital era, designing and constructability review requires excellent high end computer resources. Proper maintenance of data and model components is the key to successful utilization of BIM Modeling for Facility management. 

Effective facility management – An overview

Accurate data and efficient design presentation is the key to effective facility management. Facility Managers rely a lot on the completed AS BUILT model developed by the BIM Engineers and Architects to work on the management of a building infrastructure. It is important to know the material requirements, quantities and the assets in terms of material and components (ArchitecturalStructural and MEP), space planning. Spread out of the furniture and other components in a particular area provides a deep insight on how the building maintenance can be planned. The amount of energy that is emitted from a building, sunlight absorption, energy expenditure of building etc. needs to be monitored and calculated by Facility Managers. 

A complete and detailed BIM Model with As-built data will assist the Facility Manager in proper maintenance and replacement of overall Assets and building in long run. Digital conversion of Survey drawings or Scans into AS BUILT Models plays an important role in having wholesome data for Facility Management. 

Architects, Engineers, Product Designer and Manufacturers are developing BIM Families that can be used for further modeling purposes or manufacturing purposes. These data offer complete information of the components, equipment’s, furniture etc. You can actually get specific data input for a specific area from the Architects or the Manufacturer. Example: The BIM Model will consist the brand of plumbing fixtures that have been used, brand of electrical equipment’s or the HVAC ducts, pipes etc. used in the building during construction. 

You could have asset tagging done that can directly take you to the manufacturers website and help you get the same brand of commodity for your building if the older one is worn out.  

BIM Model for Facility management is much beyond only data. Developing a sustainable BIM Model for estimating Energy consumption and preservation is also another interesting part of Virtual construction Modeling. Added cost of building envelop or any other design change post construction can be added in the costing and budgeting “5D” data within the models. Time line scheduling of the phase wise building construction can be determined and presented using “4D” and design can be validated by using “3D BIM Model”. 

Conclusion: 

BIM Model for facility management needs to be a complete model with accurate data across all construction phases such Design present ability, constructability and BIM compliant, Data rich and sustainable. Such BIM Models are extremely useful for the Facility Manager and shall provide great assistance through overall building maintenance and renovation of building when needed. All these features are making BIM Modeling a very interesting process for Facility Management Companies globally. There is an anticipation of around 20% to 30% growth of BIM Modeling utilization in this field by the end of 2019.
