Overview
ISO 7078:2020 - Buildings and civil engineering works - Procedures for setting out, measurement and surveying - Vocabulary - is an international vocabulary standard that defines terms commonly used in setting out, measurement and surveying for construction and civil engineering. Published as the second edition in 2020, the document replaces ISO 7078:1985 and provides a harmonized language to improve communication among surveyors, engineers, contractors and other construction professionals.
Key topics
The standard organizes terminology into focused sections and provides internationally preferred terms (with country‑specific synonyms where applicable). Key technical topics include:
- General measurement concepts: measurement, measurand, measuring instrument, measurement result, measurement error, metrology.
- Setting out and surveying: setting out (laying out), coordinate systems, geodetic vs. local systems, level, height.
- Positioning and GNSS: GNSS, GPS, differential GNSS, real‑time kinematic positioning (RTK) - note: RTK is described as enabling positioning with precision better than 10 cm.
- Measuring equipment and parts: measuring tools, measuring instruments, measuring systems, ancillary and auxiliary equipment, gauges.
- Quality and calibration: measurement standard, calibration, testing of measuring instruments, measurement uncertainty (conceptual coverage).
- Scales and methods: entries on scales, reading, observation and measurement methods used in building and civil engineering surveying.
The publication contains a foreword, introduction, bibliography and index; there are no normative references. It was prepared by ISO/TC 59/SC 2 (Terminology and harmonization of languages).
Practical applications
ISO 7078:2020 is primarily a vocabulary reference to ensure consistent use of terms across international construction projects and multidisciplinary teams. Typical uses:
- Producing clear technical specifications, contracts and tender documents that involve surveying and setting out.
- Aligning terminology in quality assurance, site measurement procedures and calibration records.
- Supporting interoperability between surveying teams, equipment vendors and software by providing agreed definitions for concepts like GNSS, coordinate systems and measurement uncertainty.
- Training, education and documentation for surveyors, site engineers, architects and measuring technicians.
- Harmonizing language in cross‑border projects and international procurement.
