Ensuring a rectangular structure possesses right angles at its corners is a fundamental step in construction. This process involves verifying that the building’s layout forms a true rectangle or square, depending on the design. An example would be checking that the foundation walls are precisely perpendicular before erecting the framework.
Accurate alignment is critical for structural integrity and aesthetic appeal. A properly aligned building experiences even weight distribution, minimizing stress and potential for collapse. Furthermore, precise corners facilitate the seamless installation of fixtures and finishes, enhancing the building’s overall appearance and value. Historically, various techniques were employed, from simple rope and peg methods to the use of advanced surveying equipment in modern construction.
