Top 10 Errors & its solutions in Revit
Errors & its solutions in Revit
Imagine the site team telling you that while installing equipment on a project they found a major issue with the drawing in which a pipe and a beam are occupying the same space. To resolve this issue you rework the design, by which the project schedule is impacted and the construction is halted until the issue is fixed. But the impact on the project cost and schedule is irreversible.
Using traditional tools and techniques it becomes difficult for the project team to identify conflicts like these before the construction begins since a construction project involves multiple disciplines and the amount of information the project members must account for is substantial and vulnerable to human error. The emergence of the Building Information Modelling(BIM) process, has transformed how construction projects used to be done, the constructability issues can be identified in the pre-design stages to avoid errors in the design and one such BIM technique is the Clash Detection.
To understand what is Clash Detection first one needs to understand, what is a clash? A clash occurs when two elements in the design occupy the same space, for example, a pipe passing through a duct.
These clashes can be both intradisciplinary or interdisciplinary meaning the MEP elements may clash with other MEP elements or Structural elements. Navisworks is a powerful tool used to generate a detailed clash report with individual images showing the clashes between the elements in the model.
The clashes can be classified as Hard, Soft, and Workflow clashes. The clashes where two elements in the design are interfering or colliding with each other are Hard Clashes, whereas if the design demands certain geometric tolerance between the elements and the design lacks that space it is a Soft clash, for example, an HVAC system requires space to allow for maintenance workers to operate into service the system, a Workflow clash occurs when there is a scheduling issue between work crews and equipment fabrication, delivery and installation in the project timeline.
Clash detection, therefore, is the technique of identifying if, and where, or how, two parts of the building are interfering with one another. Hence, Clash detection is a powerful BIM technique for identifying the conflicts within the virtual design.
Constructability is a project management tool to analyze construction processes from start to finish during the pre-construction stage to avoid any obstacles in the actual construction stage. Clash detection is a vital part of the constructability analysis to review and solve the issues arising with the building elements interfering with each other in conflict with the design demands. BIM Coordination Process includes Clash Detection reports, constructability reviews, and virtual or personal coordinated meetings with concerned stakeholders.
Due to the growing adoption of building information modeling in the construction projects, it has allowed for easier sharing of information between all project stakeholders using Integrated Project Delivery(IPD), where the project consultants, contractors, architects/designers, and the client has access to every development in the project. This collaboration has empowered architects, structural engineers, and MEP engineers to review the clashes and resolve them in the live model, avoiding the traditional RFI’s(Request For Information) and change orders.
Clash detection is the essential part of the design process in the BIM workflow and can bring benefits to every stakeholder in the Construction project by :
Clash detection benefits through advanced and robust technology are driving project owners, contractors, architects, engineers, and stakeholders in the construction industry to embrace BIM to maximize productivity. Clash detection helps in real-time review and resolution of clashes, saving on rework and material costs, and keeps projects within the budgets and schedule.
BIM-LCA is an optimal process towards achieving sustainable development, environmental protection, and ameliorating the decision-making process in the construction sector by combining rich data about building materials through LCA databases and easy information management with the BIM processes and tools.
66% of construction companies say digital transformation is a key priority for much-needed changes to processes, business models, and ecosystems. Digital transformation to address the top industry challenge of completing projects on time and within budget.
