by Kimberly Smith on May 05, 2012 09:27:34 AM Since few years Building Information Modeling BIM is playing a vital role in construction industries. Building Information Modeling has a bigger influence in improving the production in construction sector. Thus BIM nowadays can be called as smarter way towards efficient construction progress. BIM is most recent invention and contribution of IT sector towards construction sector. It is also considered as an innovative gift by IT development sector to improve and develop construction sector to cope up the modernized facilities and luxuries over the globe. BIM helps to improve the construction drawings, thus resulting into error free drawings.
BIM is a single platform in which different views like sectional, plan; side views etc. are coordinated together. After the coordination a single detailed 3D model is created using various software’s. This model can be called as smart BIM model and is used at the construction sites for further construction activities. By working with BIM we can even plan steps of progression along with time frames as well as cost estimations. This time frames and costs estimations are specialized features provided by BIM and are called as 4D and 5D respectively. BIM also provides the BOQ’s i.e. Bill of Quantities or BOM’s i.e. Bill of Materials as well as time based data schedules. These BOQ’s are implemented at construction site when actual work is initiated.
Construction of complex infrastructures is impossible without applying design concept in BIM. So the structural engineers by applying their design concepts create 3D BIM models. Thus after creating models these are delivered to clients for further process of construction and work can be easily initiated at sites with the help of 3D BIM smart data rich models.
Journey from BIM to Construction / Integration stages between BIM and construction:
The journey from BIM to construction consists of following integrated stages:
1.Basic Conceptual Designing:
In this stage structural engineer, an architect develops their ideas and concepts fulfilling the clients requirement. Coordination, collection of ideas, selection of most feasible way to proceed, technical resources availability are the major steps included in under this phase.
2.Final designing and 3D modeling:
Implementation of above ideas and concepts contributes towards final designing and final construction drawings are created using design concepts. Using this drawing 3D BIM models are created by experienced modelers.
3.Tendering Stage:
The process of handling over all the BIM documentation as well as BIM model to contractor can be called as Tendering stage. Overall cost estimation and pricing is done in this stage.
4.Construction Stage:
The contractor’s estimations and documentations help to initiate or start up with actual construction at site.
Thus, there are four above described integration stages between BIM and Construction process.

by Kimberly Smith on May 04, 2012 12:14:42 PM • BIM transition in medium size firms:
For medium size firms BIM acts as an exciting new methodology for structural and architectural building designs. Before implementation of BIM for medium size firms many questions and issues will arise about the technical knowledge of members of the firm, delay in projects due to introduction of newer technology and about increasing costs due to delay and other factors. Such question and issues about BIM introduction can be easily solved by conducting basic training as well as effective planning of implementation of BIM. Thus through proper planning and small preparation, BIM can be swiftly and easily introduced into medium size firms without much interference and disturbance.
• Getting Started with BIM:
Implementation of BIM in medium size firm can be called as Process change or Culture change phenomenon. The members of firm should be equally involved in the decision making of transition to BIM and should prepare themselves for changes in technology. In larger firms, the method of transition of BIM is done one by one people to people and work outs smoothly without much interference created. But in medium and small size firms entire teams are equal contributors in decision making and the activities during BIM transition.
Best option to start with BIM services is to outsource the BIM training for internal staff members. For getting started with BIM one of major aspect of concern is installation of new software and also server needs to be improved. For example high configuration PC’s are to be required for high quality of 3D rendering and animation for BIM.
• Getting Familiar with BIM environment:
Moving the whole team to newer technology sounds little bit risky. Thus the team members of medium sized firms have to go through struggling period during BIM transition. Getting familiar with newer BIM environment becomes very difficult for medium sized firms due to shorter deadlines. It becomes very important to consider the training period of BIM as an investment and everybody should equally involve in activities so that productivity may not get affected.
The best idea of BIM implementation is to provide training on actual current working projects. This results into two sided benefits of better training activities without affecting productivity by keeping project completion time constant.
• Planning after BIM Implementation and Training:
After completion of well planned training session on pilot projects, it’s time for evaluation or assessment. For assessment of trainings members need to start up with any dummy project if time persists or else with next upcoming project. It becomes easy for team members to get acquainted with BIM due to planned training session on current projects. Along with starting new project a detailed time evaluation should be done to calculate advantages and effectiveness of BIM implementation.
In this way smooth BIM transition takes place in Medium sized firms with well planned trainings as well as mutual coordination and support of team members of the firm.

by Kimberly Smith on May 02, 2012 09:24:15 AM Revit means revise it or revise instantly. Revit is the only platform for the architects to share their different architectural design concepts as well as interior designing concepts finally to create a new innovative design using the concept of smart and intellectual modeling. The architects utilizing the concept of Building Information Modeling in Revit Architecture which results into high quality and accuracy of architectural designs.
Earlier architects made use of pen, paper to show their architectural concepts which was too tedious activity and utilizes a massive time for designing. After pen, paper design activities, architects used concept of Computer Aided Design making use of softwares like autocad. Architectural designs brought a change innovation of Computer Aided Design concept. Then came the concept of CAD based designs with 3D parametric feature. It means the elements and designs earlier drafted in 2D using autocad were converted into 3D objects after further invention of autodesk Revit software. Revit software brought a new idea of Building Information Modeling which helped architects for exploring their innovations in design concepts thus is called as smart modeling.
Apart from smart modeling revit also provides high quality of design and construction documentations. Thus working in revit architecture not only provides smart modeling but also the high quality of documentations essential for construction. Two more features are added to architectural models working with revit architecture that are 4D and 5D. 4D actually relates to time frame added to 3D models which gives actual time required for creation of complete 3D model during whole project cycle. 5D means addition of costing feature 4D based architectural models which gives overall cost analysis for a particular ongoing project. Thus revit architecture provides the initial smart modeling, timeframes or time of completion of project, cost analysis or costing of project as well as high quality of documentation required for construction.
Revit Architecture – Special Features:
1. High Quality Rendering and Visualization
Revit architecture provides you with various visuality functions which enhances the advanced photorealistic views as well as real time rendering. One can visualize actual view of building prior to construction which is one of the most impressive features provided by revit architecture.
2. Individual Architectural Families
In revit architecture one can create architectural families by its own innovative ideas and concepts like architectural railings, doors, windows, stairs etc. using fewer commands and tools.
3. Revit Project Work Sharing
This feature of work sharing enables us to divide the whole project work depending upon ones potentialities and capabilities among the team members which further helps in completing project faster.
4. Clash Check or Interference Check
Clash check helps to identify and thus solve the clashes between the elements in 3D architectural models.
