Construction diary

from Wikipedia, the free encyclopedia

The construction diary should serve as documentation of the development process of a building.

Legal basis

The construction management is upon agreement of the service profile according to HOAI , service phase 8 u. a. obliged to keep a construction log.

In addition, most of the executing companies keep their own construction diary for internal time documentation (or as a collection of the individual time sheet sheets).

The contents of these two documents differ in the way they are recorded.

The construction diary should daily, but out at each site visit at least and by all stakeholders ( construction manager , building owner and craftsmen ) be signed. From a legal point of view, the construction diary is evidence that stands in court .

The term construction diary is also used for personal documentation by private builders when building their own homes. This form serves as a reminder and generally has no legal meaning.

Information in the construction diary

  • date
  • Object (for example: Single-family house, Mustermann family),
  • Weather (temperature, cloud cover, precipitation),
  • State of construction,
  • Engineers present , site managers, other parties involved (client, site inspector, etc.)
  • Trades present (carpenters, bricklayers, plumbing ...) and their daily work,
  • Number of craftsmen in a company and, if applicable, the working hours or number of hours,
  • used equipment / machinery, possibly with operating times and downtime or disorders,
  • Construction materials used (e.g. concrete, paints, primers), if necessary with information on quantities and installation conditions,
  • Disruptions and deviations from the planned construction process:
    • Delays (comparison of the construction schedule with the actual level of performance (target / actual comparison)),
    • Defects and structural damage (text, photos, sketches),
    • Obstacles that could delay the planned process (e.g. obstacles in the building site)
    • Registration of concerns about the specified construction,
    • detected errors during construction ,
  • Construction work for which a site manager has to be on site (concrete work, structural work),
  • Instructions and injunctions to contractors and craftsmen,
  • agreed additional orders ( supplements ),
  • Tests carried out (e.g. fresh concrete) and measurements,
  • Route of cables / pipelines before backfilling or plastering (photos, sketches),
  • Plans that were handed over on the construction site , possibly with an index, in the case of plan changes during construction ,
  • Installation and operating instructions for built-in devices such as B. fans, doors, as attachments to the construction report
  • Acceptance of construction works and partial acceptance,
  • Special incidents (complaints from neighbors, accidents , damage to neighboring properties),
  • Photo documentation of the state of the building, the visible defects, the handicaps, possibly the building materials (quality control) and important building measures and their work processes.

practice

In daily practice, the construction diary is increasingly being kept using software on portable devices. The advantage is the access to central company lists, the administration of photos and the e-mailing of the construction diary to predefined distribution lists. In addition, texts that have been entered once are suggested using the auto-complete function when they are entered again, so that the overall amount of paperwork can be significantly reduced. Because, especially in the field of construction site documentation, there are recurring texts. In addition to photo management, good programs also allow building plans, delivery logs and correspondence to be added to the current daily construction report, so that later it is easier to understand which plan statuses were available on which day.

Smartphones and tablet computers can serve as input devices that can be used, for. In some cases, it is also possible to dictate texts, so that under the adverse conditions of the construction site it is not necessary to type on small device keyboards. Automatic insertion of meteorological weather data and assistance with defect management are also part of the functional scope of some of the mobile applications.
