asbuiltteckningar

Asbuiltteckningar, often called as-built drawings or record drawings, are the set of drawings that document the final, constructed condition of a building or infrastructure project. They show what was actually built, including any deviations from the original design, such as altered layouts, dimensions, wall placements, openings, and the exact locations of installed systems. These drawings may be produced during construction or after completion to reflect the as-built state.

The primary purpose of asbuiltteckningar is to provide a reliable reference for operation, maintenance, and future renovations. They capture changes made on site due to field conditions, redesign decisions, or change orders, and serve as a baseline for facilities management. They are typically used by building owners, operators, and maintenance teams to plan repairs, expansions, or retrofits and to ensure compliance with permits and safety requirements.

Contents commonly included are architectural, structural, electrical, mechanical, and plumbing details, with updated dimensions, room names, equipment locations, materials, and installation specifics. The drawings also contain revision histories, dates, and the names of the parties responsible for updates. Deliverables may be in both printed formats and digital formats (CAD, PDF, or BIM models), and are often part of the project handover package.

Production and standards vary by region and contract, but asbuiltteckningar are usually prepared by the contractor or design team and verified by the architect or engineer. They reflect conditions at a specific time and can become outdated if not maintained; integrating them with digital models and facility management systems is a common best practice for long-term accuracy.
