What is Level?
Level is a unit or datum point of measurement or reference, indicating if a surface or object is true to horizontal, vertical, or height.
Definition
Purpose
Leveling is the process of transferring precise elevations of points so that items can be placed on site at the proper heights and building elements are in the correct position to achieve their intended function. Building at proper levels of building components ensures the integrity of the structure and the quality of the build, and prevents performance or safety problems caused by items placed incorrectly.
Measurement of levels is used by construction personnel in almost all project tasks, from pouring foundations to applying finishing materials. Proper levels being implemented will mean walls are plumb and straight, floors are level, and the structure will allow proper drainage. Measuring levels helps different trades work in coordination to achieve a single elevation on the project.
Examples of Use
- A contractor will lay out the level reference point for the floor pour using a laser level to create a flat, smooth slab.
- A carpenter will verify walls are plumb by sighting with a spirit level.
- Grading around the building is performed to establish desired levels and slopes.

Notes
- The word "level" can be used to describe both the reference point and the instrument.
- Spirit, laser, water, and digital levels are common.
- Poor leveling results in building deficiencies, performance problems, finishing flaws, and improper installations.
- Correct leveling is imperative for accurate, safe construction and good building performance.
