Most people have a general understanding of the architectural lifecycle, but what exactly does the full lifecycle of BIM technology entail? The editor believes the complete BIM lifecycle includes the following stages:
1. Decision-Making Stage: At this initial phase, it’s essential to evaluate the project’s feasibility and assess the accuracy of estimated engineering costs to make informed decisions. Having access to BIM archive information from similar buildings provides valuable references, enabling more scientific and confident decision-making.
2. Design Phase: The architectural BIM model is seamlessly transferred to the structural engineering team. After analyzing building stresses and completing the structural design, the structural model is integrated. Next, the combined BIM model—including architectural and structural data—is passed to the equipment installation team for designing systems such as plumbing, HVAC, and electrical. At this point, the BIM model contains comprehensive digital information covering the building, structure, and installations.
3. Bidding Stage: BIM models allow for direct calculation of building quantities. By applying pricing rules, these quantities form the basis of the bidding documents, enabling quick and accurate cost control. Contractors can quote independently based on the detailed bidding requirements, making the bidding process faster and more transparent.
4. Construction Phase: By integrating time schedule data with the BIM model, 4D construction simulations become possible, while 5D simulations enable stage-by-stage cost analysis. Additional nD simulations can also be conducted as needed. Both client and contractor can base construction progress payments on the same accurate 5D BIM model, ensuring clear, timely payments without over- or underpayment issues.
5. Operation Phase: BIM models support digital management throughout building operation. They assist in optimally placing surveillance cameras and implementing security measures, as well as maintaining building facilities. In emergencies such as fires, BIM models provide scientific guidance for quick evacuation and rescue efforts.
6. Demolition Phase: BIM technology helps analyze and optimize demolition plans, including evaluating the reasonableness of explosive placement in blasting operations. Simulations of blast reactions predict the impact on the building and surrounding structures. BIM also facilitates calculating the residual value of demolition materials, turning waste into resources. Overall, digital BIM models contribute to creating a digital city infrastructure that can evolve into a smart city.
We hope this overview helps establish a clear understanding of the full lifecycle of BIM technology and proves useful to everyone.
