Cadmap Limited survey using fully connected control for the highest accuracy when surveying properties, we often laser scan buildings but also still use Total stations and traverse from outside to inside and into each room to laser the structure of the building. This data then gets exported and processed and drawn in AutoCAD.

All surveys carried out by Cadmap are to RICS Specifications.

The RICS (Royal Institution of Chartered Surveyors) measured building specification refers to the guidelines and standards used to measure and describe buildings in terms of floor areas, dimensions, and other key physical characteristics. Below are the key points typically included in the RICS Measured Building Specification:

1. Measurement Standards

  • RICS specifies measurement standards for building areas, which include Gross Internal Area (GIA), Net Internal Area (NIA), and other specific floor area definitions.
  • These standards are used to ensure consistency in measurements across the industry.

2. Gross Internal Area (GIA)

  • Defined as the total floor area within the external walls of a building, including all areas occupied by partitions, columns, staircases, and internal walls.
  • Excludes external elements like balconies, and external staircases.

3. Net Internal Area (NIA)

  • Refers to the usable floor area of a building, excluding areas like internal walls, common areas, staircases, and shafts.
  • Often used for the leasing or sale of properties to measure the usable space available to tenants.

4. External Areas

  • The RICS specification may include guidelines for measuring external areas like courtyards, yards, or surrounding land, which are often needed for certain property valuations.

5. Ceiling Height

  • Standard measurement practices for ceiling heights, which can impact the overall valuation or classification of a building space.

6. Walls, Columns, and Partitions

  • Specifications for how to measure walls, columns, and partitions, and whether or not to include them in area calculations. Generally, the thickness of external walls may be included in GIA but not in NIA.

7. Building Components

  • Specific definitions of different building components such as internal and external doors, windows, corridors, service areas, and lift shafts.

8. Architectural Elements

  • Detailed instructions on how to measure architectural elements such as balconies, terraces, canopies, and mezzanines.

9. Sub-floor and Ceiling Void

  • Space below floor level (for ducts, cables, and services) and above ceiling level (for the mechanical systems) should be measured in certain cases depending on the project specifications.

10. Building Classifications

  • Buildings may be classified by their use (office, retail, residential, industrial, etc.), and RICS specifies how to classify buildings and their spaces for accurate measurements.

11. Measurement Tolerances

  • Guidelines for acceptable tolerances in measurements, accounting for factors such as settling or material shrinkage over time.

These are general guidelines and can vary depending on the specific context (e.g., new construction vs. existing buildings). It's essential to consult the full RICS Measured Building Specification document for detailed and specific measurement criteria.
