| Daily operations | For various types of work on a construction site, it is necessary to track the operational volumes of execution. This is complicated by the fact that automatic progress measurements are very often too expensive or impossible, so a live "survey" of the performers is the only possible option. Examples of types of work (depending on the object being built) for which construction logs can be kept:

| Subcontractor control | Subcontractors play an important role on a construction site and can often be a problem in the implementation of a project. In addition to daily operations control, the following can be kept:

Real-life cases where poor log-keeping led to disasters
Collapse of the Hard Rock Hotel in New Orleans (2019)
On October 12, 2019, the under-construction 18-storey Hard Rock Hotel on Canal Street partially collapsed. Three workers were killed and more than ten were injured.
The cause was officially established — the inspectors performed their job negligently and did not visit the site. Although the workers on site saw the defects and even filmed them on video. However, the absence of a system for capturing and escalating information "bottom-up" led to this tragedy
Manhattan crane collapse (2008), Crane boom hook drop (California, FACE Report 96CA003)
A very common situation — problems with cranes. For example, in California — two days before the incident, the slings attached to the load broke, as a result of which the boom recoiled and swayed back and forth. After this, a thorough inspection of the cables was not performed. The fact that the slings were damaged in the incident — no one documented it, no one scheduled an inspection. The result — a person died.
