LSM is used mainly in the construction industry to schedule resources in repetitive activities commonly found in highway, pipeline, high-rise building and rail construction projects. These projects are called repetitive or linear projects.
A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...
In the case of roads or other linear infrastructure, a chainage (derived from Gunter's Chain - 1 chain is equal to 66 feet or 100 links) will be established, often to correspond with the centre line of the road or pipeline. During construction, structures would then be located in terms of chainage, offset and elevation.
By extension, chainage (running distance) is the distance along a curved or straight survey line from a fixed commencing point, as given by an odometer. The chain has been used since the early 17th century in England, and was brought by British settlers during the colonial period to other countries around the globe.
Linear referencing is suitable for management of data related to linear features like roads, railways, oil and gas transmission pipelines, power and data transmission lines, and rivers. It is used in engineering , construction , and utilities management.
For example, in a December analysis of Texas Department of Transportation data, NBC 5 Investigates found that Dallas had experienced 207 traffic fatalities in 2024, an increase from the 205 deaths ...
Construction management (CM) aims to control the quality of a construction project's scope, time, and cost (sometimes referred to as a project management triangle or
Refractive errors, some of the most common types of vision problems, cannot be treated with medication, for example. Instead, glasses, contact lenses, and surgery are used to correct them as ...
