Instrument
HM Land Registry: 1862 Act Register, glossary, published on 7 November 2014 by HM Land Registry, defines an instrument as: ‘A formally executed written document such as a deed or a will which evidences an agreement or act.’
The term instrument might also refer to a tool used for precision work, a measuring device or other piece of equipment.
In the UK construction industry, a variety of instruments are used across different stages of construction, from site surveying and design to building and finishing. These instruments can be broadly categorised into types based on their function:
- Theodolites - used for measuring horizontal and vertical angles.
- Total stations - integrates electronic theodolites with distance measurement to map and survey a site.
- Levels (dumpy level, laser level) - used to establish or verify points in the same horizontal plane.
- Gps surveying equipment - for high -precision location and mapping using satellite signals.
- Tape measures and measuring wheels - basic tools for measuring distances on -site.
- Concrete test hammers - used to assess the strength and quality of concrete.
- Soil testing kits - includes devices like penetrometers to check soil compaction and stability.
- Moisture meters - measure the moisture content in materials like wood, concrete, and soil.
- Rebar locators - used to detect the presence of reinforcement bars within concrete.
Health and safety instruments:
- Gas detectors - detect the presence of hazardous gases on construction sites.
- Sound level meters - measure noise levels to ensure they are within safe limits.
- Dust monitors - assess air quality, particularly the concentration of particulate matter.
- Temperature and humidity meters - monitor environmental conditions on site.
Measurement and layout tools:
- Laser measuring tools - provide quick and accurate distance measurements.
- Plumb bobs - used to check the vertical alignment of structures.
- Spirit levels - ensure horizontal surfaces are level.
- Builders' squares and angle finders - measure and mark angles and ensure accurate cuts.
Testing and commissioning instruments:
- Electrical testers - used to ensure electrical installations meet regulatory standards.
- Pressure gauges - check the pressure in systems like plumbing or hvac.
- Thermal imaging cameras - identify heat loss, insulation issues, and electrical faults.
