The following specification particularly describes the invention and the manner in which it is to be performed.
FIELD OF INVENTION
[0001] The present invention generally relates to building engineering and design. More specifically, the present invention is related to a system and a method for performing building design calculations and analyses.
BACKGROUND OF THE INVENTION
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] Building engineering and design is a multifaceted discipline that involves creating structures that are safe, functional, efficient, and compliant with a wide array of regulatory standards. This process requires a detailed understanding of various domains, including architectural planning, structural integrity, Mechanical, Electrical, and Plumbing (MEP) systems, Heating, Ventilation, and Air Conditioning (HVAC) systems, and sustainable construction practices. To meet the diverse requirements of modern construction projects, engineers and designers must integrate complex systems and adhere to stringent safety and environmental standards, all while optimizing costs and resources.
[0004] The design process relies on the analysis and integration of vast amounts of data, including equipment specifications, material properties, engineering standards, historical project records, and market price trends. This data is often stored in disparate locations and presented in multiple formats, including 2D CAD drawings, 3D models, PDFs, and text files. A persistent challenge in the industry is the conversion of 2D CAD drawings into 3D Revit models, which are essential for modern Building Information Modeling (BIM) workflows. This conversion process is labour-intensive, prone to errors, and often requires significant manual intervention, resulting in inefficiencies and delays in project timelines.
[0005] Another critical building design challenge is accurate calculations and analyses across various domains. For example, MEP calculations involve determining parameters such as lighting requirements, power distribution, cable sizing, ductwork and ventilation systems, water supply, and drainage systems. These calculations ensure the systems of the building operate efficiently and meet the intended functional requirements. However, the reliance on separate tools for each type of calculation leads to fragmented workflows and increases the risk of inconsistencies. Engineers often face difficulties in integrating these calculations into a cohesive design while maintaining accuracy and efficiency.
[0006] Ensuring compliance with regional and international building standards adds another layer of complexity. Building codes and regulations vary widely depending on the project’s location and requirements. Designers must manually verify that their designs meet these standards, which is a time-consuming and error-prone process. Changes in design parameters often necessitate a re-evaluation of compliance, further complicating the workflow. This creates a need for efficient mechanisms to streamline compliance verification and ensure adherence to applicable regulations without compromising project timelines.
[0007] Cost estimation and resource optimization are also critical aspects of building design. Engineers must accurately estimate the quantities of materials and equipment required for the project while considering real-time market prices and historical data. However, the lack of integration between design processes and cost estimation tools makes it challenging to dynamically assess the financial feasibility of design decisions. Additionally, generating comprehensive outputs such as MEP reports, bills of quantities, and engineering layouts requires significant effort and often lacks real-time updates when design changes are made.
[0008] The inherent complexity of integrating diverse data sources, performing domain-specific calculations, ensuring compliance, optimizing resources, and converting 2D CAD drawings into 3D Revit models presents substantial challenges in modern building engineering and design. As projects grow in scale and complexity, overcoming these challenges is critical to improving efficiency, reducing errors, and meeting the evolving demands of the construction industry. These challenges highlight the need for an integrated, automated system to address the inefficiencies and limitations of traditional methods.
