The vital importance of 3D BIM model-based design evaluations for construction project success
Construction business is a type of hazardous and uncertain business which requires greater capital and it also implies that a failure can lead to massive money risk. Several buildings and structures can be found in past that collapsed due to poor design reviews and planning. Post disaster examination uncovers potential safety issues in poorly constructed structures. There’s a message in every structural disaster that any size of construction projects without legitimate planning, audit, examination and coordination, puts itself at equivalent hazard.
Mark-ups and mock-ups
Handwritten mark-ups on hard copies of drawings is nearly to be history soon. 2D shop drawings audit is being the business standard and so to get the engineering design details, complete detailed model for mock ups are usually build allowing all parties the chance to provide intensive feedback to improve building construction both functionally and aesthetically.
Along with making full model mock-up, 2D design review strategy is usually simple and budget is set to low. 2D shop drawings can be hard to picture and requires extensive experience in reading 2D drawings. Few issues may be overlooked by engineers that may cause more serious issues later. Procedure for solving these issues is to resubmit for audit which is usually postponed because of sometimes data is not clear or RFIs are included.
3D BIM Model based design reviews
Model based building engineering reviews can overcome the weakness of 2D shop drawings reviews by overlaying 3D BIM models in plan and review process. 3D BIM models gives the advantage of coordinating design options in respect to construct-ability and pre-fabrication whereas 2D drawing review process was lacking in these areas.
3D BIM models considers the extensive and exact plan reviews, with several object properties thereby decreasing the cost of auditing and submission time. Feasible plan choices and design options can be effortlessly displayed and can be updated continuously during design reviews depending upon end client’s feedback. 2D design reviews takes longer time which can be settled within 50% of time using 3D BIM model based reviews.
Design review stages
When transitioning to 3D BIM model reviews from project stage to stage without effective planning or collaboration from parties involved, it results in tedious and labor intensive tasks for repetitive modelling and redesigning. Parties are rarely included during developing the 3D BIM models and are not made aware of estimations of models and gravity of information. Therefore, majority of 3D BIM models are submitted without determining that how they are going to be used.
3D BIM models can be used for scaling up the details as the project progresses. Progressive complex choices can be made easily. Initially the 3D BIM models are basic which can be used for picturing the 3D BIM aspect to identify clashes and permit parties to occupy the space.
In design development, various design alternatives can be iterated progressively to mimic the engineers and designers inputs. This procedure of producing alternatives is shrewd, knowledgeable and helps in taking good judgement.
At the stage of executing Construction Drawing Services, collaborative efforts required are more to reflect the planners / engineers / general contractors / sub-contractors / consultants inputs. While leading the audit process using 3D BIM models, the designer can easily comprehend with the space and can modify the structural aspects immediately depending upon limitations. The 3D BIM model will be upgraded to LOD 400 standard which allows contractual workers and sub-contractors to utilize it for fabrication purposes. In this manner, we can upgrade the 3D BIM models in an organized way reducing the quantity of changes and choices that are required at field.
In operations stage, facility managers are provided with chance to change models created in prior stages to suit facility management. 3D BIM model based design reviews is now being adopted rapidly right from the initial project inception stage and the feedback circle is being reapplied considering inputs from every party involved including conceivable channels particularly the facility managers and owners. This workflow concepts the Integrated Project Delivery or IPD approach.
Conclusion
Improved speed and accuracy of 3D BIM model based design reviews significantly reduces the burden during engineer’s drawing approval and shop drawing audit stage making it simpler to spot errors and steer design and construction to be error free. The point where an engineer dismisses the submission by commenting “reconsider and resubmit”, the 3D BIM model based building review enables simple and speedy change. Sub-contractors gets advantage in picturing the errors and helps in mitigating risks and incorporating mentioned changes. In some cases, construct-ability issues requires end client to differentiate how a finished building will be utilized to designers and architects.
Reducing the hazard to the construction business is the advantage offered by advanced digital technology. Businesses are being progressively virtual and out buildings being complicated, we must discover usage of design tools to accommodate plans expectations.
It will not be feasible to drive complex building systems in 2D drawings that allows errors to be missed out. 3D BIM model based reviews encourages to attain error free design and construction in a more cost effective way allowing all parties involved to connect with designs and construction through an agreeable medium.
Combining MEP BIM Services with Architectural, Civil and Structural disciplines in 3D BIM model based reviews helps in making room for design changes and resolving costly clashes.
