Autodesk Forma – Area Metrics


Area analysis is a critical aspect of architectural and construction planning, providing essential insights into space allocation, functionality, and compliance. Here’s a more detailed look at each type of area analysis:

Gross Building Area (GBA)

This encompasses the entire floor area of a building, including all enclosed spaces, measured from the exterior face of the walls. GBA is crucial for determining the overall size of the structure and is often used for zoning, tax assessment, and regulatory compliance purposes.

Area Per Department or Floor

By calculating the area for each department or floor within a building, stakeholders can understand how space is distributed and utilised throughout the structure. This analysis helps in optimising layouts, identifying areas for improvement, and ensuring that each department or floor meets its specific requirements.

Parking Bays

Determining the number and size of parking spaces required for a building or development project is essential for ensuring adequate parking capacity and compliance with local regulations. Parking bay analysis considers factors such as parking demand, vehicle sizes, and accessibility requirements.

Total Areas by Function

Calculating the total area for specific functions within a building, such as office space, residential units, or retail space, provides insights into the allocation of resources and facilitates efficient space planning. This analysis helps in balancing the needs of different functions and ensuring that each area meets its intended purpose.

Circulation Space

Measuring the area dedicated to circulation paths, including corridors, hallways, staircases, and elevators, is essential for optimising traffic flow and accessibility within a building. Circulation space analysis helps in minimising wasted space while ensuring safe and efficient movement throughout the structure.

Common Areas

Evaluating the area dedicated to shared spaces, such as lobbies, atriums, meeting rooms, and recreational areas, helps in creating welcoming environments that enhance user experience and promote interaction. Common area analysis considers factors such as usage patterns, accessibility, and aesthetic considerations.

Zoning Requirements

Ensuring compliance with local zoning regulations is crucial for obtaining permits and approvals for construction projects. Zoning requirement analysis involves calculating areas for setbacks, green spaces, buffers, and other regulatory requirements to ensure that the design aligns with municipal regulations and planning guidelines.

By conducting comprehensive area analysis, architects, designers, and project managers can make informed decisions, optimise space utilisation, and ensure that designs meet project requirements and objectives. Additionally, area analysis aids in estimating costs, determining resource allocations, and ensuring regulatory compliance throughout the design and construction process, ultimately leading to successful project outcomes.
