What are the limitations of BIM in construction?

BIM models are useful in the service of program clash detection. They are utilized by the design team to coordinate major elements in such a way as to minimize subsequent redesign. However, levels of quality can vary widely depending on how much coordination has been done in the programming phase. Too often engineers drawings are not well coordinated in programming, and the expectation is that trades will rectify remaining conflicts. Yet many trades don't have BIM models, or use drafting platforms that are don't integrate with a given BIM platform. Not every trade can afford a BIM program and operator. At the end of the day, it is field sketchers and draftsmen who must address final measurements in the field, with or without BIM.

There are a number of shortcomings with BIM: firstly, specialty trades can't afford the technology and operators, and cannot generate BIM models for their work. Thus, several drafting programs co-exist - not always harmoniously - on a given project. Secondly, designers tend to become over-reliant on BIM to coordinate their various programs - many of which are incomplete until shop drawings and field dimensioning is complete. This over-reliance means they do less coordination than they used to - which means that specialty trades much pick up the slack for designers errors an omissions.

There are multiple hardware issues also which can lead to high cost in the project. Like software purchase, renew and higher graphics etc.

Superar as limitações do BIM na construção civil requer abordagens estratégicas. Investir em treinamento abrangente, promover a integração eficaz entre softwares, cultivar uma cultura de colaboração entre todas as partes interessadas e realizar revisões constantes das práticas são medidas essenciais. Além disso, a pesquisa contínua e o desenvolvimento de atualizações do software BIM são cruciais para lidar com desafios em evolução. Ao adotar essas estratégias, a indústria pode maximizar o potencial do BIM, impulsionando eficiência e inovação.

Complete buy and consensus in at all levels of the organization and all collaborators is key. The most intimidating aspect of BIM adoption is the sudden, drastic, and disruptive paradigm shift in terms of tools, technology, thought processes, and workflows. The greatest enemy of effective BIM adoption and implementation is the thought “This is how we’ve always done things and this is how we’ll continue to do things “.

Building Information Modeling (BIM) in construction faces challenges, including high initial costs, a learning curve for project teams, interoperability issues between different software platforms, and the dependence on accurate input data. The lack of universal standards, limited adoption in small projects, legal and contractual uncertainties, resource-intensive requirements, security concerns, and resistance to change are additional limitations. Despite these challenges, ongoing advancements aim to address issues and enhance BIM's effectiveness in improving project collaboration, efficiency, and decision-making processes.

• Potential data interoperability issues • Initial implementation costs • Learning curve for teams • Standardizing data formats across BIM tools • Misleading when material approval is delayed • Misleading if one of subcontractors works in traditional methods. • BIM doesn't replace the need for effective communication among stakeholders • Human judgement remains crucial in decision-making • Ongoing advancements in BIM aim to address these limitations over time

Las claves para un trabajo eficiente en BIM sería: - Elegir un software BIM adecuado - Utilizar una buena plantilla BIM - Trabajar con un CDE - Mantener un equipo formado y actualizado Por último añadiría: Analizar los errores y éxitos del proyecto para modificar el BEP en el siguiente.

BIM in the construction phase is a support ally in the measurement of work progress and estimation, therefore it does not directly influence the construction process, so it seems to me that the limitations would be human or planning in the sense of defining correctly the BIM uses that can be taken advantage of in that phase, sometimes this use does not occur due to incomplete or null planning from the BEP or not having a BIM vision that is planned from the beginning with a view to building
