Professionals in the AEC (Architecture Engineering Construction) industry utilize Building Information Modeling, or BIM, a 3D model-based concept. Building information modeling (BIM) facilitates effective collaboration between architects, engineers, and contractors (AEC) prior to the commencement of construction. It aids in the development of multi-dimensional models that incorporate both functional and physical details. Many fields make use of this technology, including but not limited to those dealing with civil engineering, plant management, mechanical engineering, electrical engineering, plumbing systems, heating, ventilation, and air conditioning (HVAC), and structural design. In this article, we will discuss the best and most free BIM software to consider if you are an architect.
What Is BIM Software?
Building Information Modeling (BIM) software is a comprehensive tool used in the architecture, engineering, and construction industries to create and manage digital representations of physical and functional characteristics of buildings and infrastructure. Unlike traditional 2D design tools, BIM enables professionals to develop 3D models that integrate various aspects of a project, including geometry, spatial relationships, geographic information, and quantities.
Furthermore, BIM software fosters collaboration among stakeholders by providing a centralized platform for sharing and accessing project data. This collaborative approach enhances communication and coordination throughout the project lifecycle, from conceptualization and design to construction and maintenance. BIM models can store information about materials, costs, and timelines, facilitating more informed decision-making.
The software’s ability to simulate and visualize designs aids in detecting potential issues early in the planning stage, reducing errors and improving overall project efficiency. BIM has become a standard in the industry, promoting interoperability and standardization across disciplines. Its adoption has led to improved project outcomes, increased efficiency, and enhanced sustainability in the built environment.
Understanding BIM Technology
BIM modeling has been around in some form or another since the 1970s; however, its evolution has been gradual. However, it wasn’t until the global adoption of the BIM process’s standards and procedures in the 2000s that the practice took its current shape.
AEC projects are growing more complicated due to global trends, while technical developments in structural engineering are enabling industry professionals to plan, build, and operate more effectively. When it comes to the AEC construction sector and project management, BIM software has been nothing short of a game-changer.
Designers can use BIM services to create a 3D digital model of a building before it is built. In addition, the BIM information contains details about the physical and functional characteristics of the building, which contribute to more informed choices.
Collaborative architectural design utilizing open BIM allows architects, engineers, and contractors to see how their individual contributions fit into the greater whole and get more done in less time.
The information that BIM software provides can help a project’s construction phase go more smoothly and productively, and it can also help future building maintenance and operations be better understood. Preventative maintenance, asset tracking, facility management, and even future restoration can all benefit from the use of the BIM tool for owners.
How Is BIM Used During the Design and Construction Phase of a Building/Facility?
Engineers use BIM (Building Information Modeling) software, such as Autodesk Construction Cloud, BricsCAD Bim, and Autodesk Navisworks, in the design and construction of modern buildings. Here are some of the ways in which its use can improve design and construction processes and help save time, money, and lives.
Step 1: Modeling
BIM authoring tools allow architects to create accurate 3D models of buildings. Before committing their ideas to the construction process, they can test the design and discover any flaws through experimentation.
Step 2: Workflow
The clients, architects, contractors, and anybody else working on the project can all access the same central database containing all of the data and concepts developed over the project’s duration. A common type of this software is hosted in the cloud, making it available to authorized users from anywhere via an internet connection. With the help of BIM software, architects may do things like:
- Energy and light analyses
- Spatial planning
- Parametric modeling
- Material choices
- Cost estimations
- Construction time estimations
In addition, using these predictions, architects may plan the most time- and cost-effective steps of the building process.
Step 3: Construction
Contractors (with the aid of the architecture firm) create the structure in accordance with the predetermined process. They can go back to the BIM model or workflow at any moment and make changes as needed. BIM helps to ensure that all parties involved in a construction project have the same understanding of the project, regardless of whether or not the workflow is changing.
Step 4: Handover
The BIM model can be handed off to the client or the FM firm once construction is complete. Finding HVAC systems or planning future renovations is much easier with a complete design model.
