With rapid technical advancement and need to deliver quick turnaround time of construction projects, it has become imperative for contractors, consulting firms, and Architectural Design firms etc. to shift from CAD to BIM Modeling. BIM owing to its parametric modeling properties, ability to provide building data along with 3D geometry has compelled companies to make shift from cad drafting services to virtual construction modeling technology.
How does the BIM technology work? Why has it become so necessary to shift boats? The key to shifting paradigms is the efficiency of construction process with virtual construction modeling. Advantages of shifting from CAD to BIM Modeling are many. But the most talked after and visible advantage is cost effective and time saving process implementation. Second advantage is parametric features and one stop point for all building related data. Right from basic 3d geometry to advance level details such as cost, material take off, project phasing etc. can be derived from a single BIM Model.
Architectural design technology is rapidly advancing and the firms that choose to remain with outdated software will experience a massive disadvantage. Every organization that chooses to stick to orthodox ways will chug along, drafting line by line, with latest versions of AutoCAD software or other 2D drawings which despite every “offset” command will be behind in the race. There are many modern alternatives with a better and more efficient way to prepare architectural documents. There was a time when Architects created manual design options and advent of AutoCAD was considered a major turning point. Building Information Modeling fever has gripped the construction industry. Though many players are still toying with the idea of BIM Implementation, many companies have started availing the “BIM Advantage” and have achieved excellent results in terms of cost and construction turnaround. Many firms missed the “BIM train,” as their firms matured and the systems were developed completely around AutoCAD. They were growing rapidly and switching software was not practical or financially apt. There are four major steps that will explicitly need to be employed to facilitate a swift and rapid transition from CAD to BIM Modeling
1) Educate and Engender:
Research all your choices. Read the reviews. Take innovative courses. Attend as many webinars as possible. Only then will the decision be made easily:
– Which software is best suited for the market you serve?
– Which will be the most efficient?
– Which will be the most cost-effective?
Become a connoisseur of understanding as many and the most plausible options from which you are able to choose.
2) Experience
Be very picky and narrow down the list to the three best choices for your firm and experience each of these for yourself. Most software companies offer free limited-time trials of their full software package. Download each one and spend some time experiencing the user interface. Try each one all the while testing ease, lack of complications, level of education required and the management that will be required later on.
3) Elect
It’s time to opt for the unsurpassed decision will be easy. Don’t make this an agonizing procedure. Be liberal with your decision on which package is best suited for your firm and just pick one of the most suitable options.
4) Implement
It’s now time to actually transition from CAD to BIM Modeling. This will take courage, reliability, and perseverance. There is no need to turn back. In step 3 you made a commitment. The firm will have to elect to be able to proceed and integrate BIM into the systems and workflow.
There is no need to give up on AutoCAD, however the work bifurcation should be smart enough to ensure that the critical phases of construction should be done with the help of BIM technology.
The elementary transfer has been from CAD as a drafting instrument to BIM which is more of a three-dimensional building structure geometry and documentation implement which also can be employed as a wide-ranging project database. BIM works in three dimensions, which not only helps to become aware of errors right from the first few steps but also helps in generating 2D drawings with a lot of ease. This diminishes changes which are usually completed at a much later stage. Ahead of this, it can be also be used to obtain building structure, pathway schedules, cost judgment etc. as per illustration updates.
