5D BIM is an evolving segment in the construction industry, comprehending the customary three-dimensions of a BIM with schedule as the fourth dimension and cost estimates as the fifth dimension. This 5D BIM sketchup helps contractors to envision the cost of the entire project, the time-line for the project, when these expenses are projected to be incurred and much more. All this happens while bearing in mind the quantities of materials resulting from the model and the productivity rate of construction staffs.
5D-BIM approach offers an exceptional opening to unite practices in design, cost and construction approaches. On the other hand it should be noted that 5D BIM approaches call for a significant change in the way construction companies work. It will be impractical to promise, a large construction company with wide spread resources, repositioning of their basic practices will be economical and lucrative.
One of the leading and a huge construction company in USA, more than 300 construction professionals working for them with a yearly construction production of $740 million, embraced 5D-BIM methodology, the trials they faced while executing the project and the teachings learned during the procedure might give us an insight about the entire transition. It may also prove to be a catalyst to comprehend the paradigm shift within the company in espousing 5D-BIM.
BIM Acceptance & 5D-BIM Consideration
The construction company has had a long affiliation with BIM models. It first estimated 5D model for a Disney project in the year 2008, however 5D models did not instantaneously include other ongoing projects within the company. It was established that the company spent approximately $0.5 million on software & hardware related to BIM.
The company is utilizing 5D-BIM on more projects and there is a universal reception amongst professionals in the company to utilize 5D-BIM on increased number of projects.
5D-BIM was predominantly accepted as a method by the senior management of the company. Vice-presidents in the company were hearing about this new concept and were eager to explore it within the company. The management was also keen to take real steps in successful implementation of BIM 5D model design in their company.
They were particularly enthusiastic about the reaction of real-time cost data comprising of design procedures, real-time quantities as design changes and real-time updates to project budgets.
In order to integrate cost estimating procedures in 5D-BIM workflow, estimators were also hired for the project. The company head-started with some pilot projects; where cost estimation was done utilizing both 5D-BIM tools and conservative tools.
These pilot projects paved a path for the company about the procedures that needed to be changed within the company for successful execution of 5D-BIM. But finally it was decided to take one step at a time to ensure that all the incremental changes were taken into consideration before occurrence of any unanticipated circumstances.
An assessment of procedure was conducted so that 5D-BIM could be executed and procedures restructured to better fit the new workflow. The team who worked on this BIM 5D project was of the opinion that the company started earning the benefits of executing 5D-BIM as they never before along with so much of data about their own internal procedures.
One of the team members quoted “it is likely to educate an old dog some new tricks” and our estimators now have a higher outlook to the whole 5D-BIM concept. They also said that the software would become simpler to use in the time to come. It was also observed that 5D-BIM alike other software tools need to be web-enabled to get the maximum advantage for on-field personnel.
Market Acceptance and Replication Probabilities
Executing 5D-BIM in large construction companies has several challenges including technological barriers that need to be overcome for seamless execution of 5D-BIM. These projects require professionals who are expert in relevant fields and have exposure to this evolving technology. There are considerable costs associated with the execution of 5D-BIM procedures encompassing hardware, software and training.
Hesitation to change is one of the biggest factors which make the task more intricate. Another is the “human aspect” that goes against this evolution as learning – unlearning and then again learning becomes a very monotonous and difficult task for professionals who know their business, making the entire adoption very difficult.
However; 5D-BIM is a new wave giving that ray of hope to entire construction industry while offering transformative experience to the construction companies.
