As-built survey, also known as record drawings, is a survey that documents the final construction of a building or infrastructure project.
It involves creating accurate measurements and detailed plans of the completed construction, including any modifications or changes that were made during the construction process.
The primary purpose of as-built surveys is to ensure that the completed project meets the initial design specifications and requirements. These surveys are also essential in identifying any construction errors, discrepancies, or omissions that may affect the building's safety, functionality, or aesthetic appeal.
In the construction industry, as-built surveys are commonly used for a wide range of applications, including building renovation and restoration, facility management, and compliance with local building regulations. These surveys are particularly useful in assessing the structural integrity of existing buildings, identifying areas that require repairs, and developing plans for future construction projects.
One of the significant benefits of as-built surveys is that they provide accurate and reliable data that can be used to plan future construction projects. This data can be used to identify potential issues that may arise during the construction process, which can help contractors to develop more accurate cost estimates and timelines. It can also help to avoid costly delays and unexpected expenses that may occur due to inaccurate or incomplete construction plans.
Moreover, as-built surveys can provide a comprehensive record of the building's construction process, which can be used as evidence in legal disputes or insurance claims. This documentation can also help to establish the building's historical value, which may be relevant for heritage or conservation purposes.
In terms of cost, as-built surveys in London can vary significantly depending on the size and complexity of the project. Typically, the cost of an as-built survey is calculated based on the square footage of the building and the level of detail required in the survey. For example, a simple as-built survey of a small residential property may cost around £1200, while a more complex survey of a commercial building or infrastructure project can cost several thousand pounds.
In conclusion, as-built surveys play a vital role in the construction industry by providing accurate and reliable data on the completed project's specifications and requirements. These surveys can help to identify any errors or discrepancies that may affect the building's safety, functionality, or aesthetic appeal, and they can provide valuable information for future construction projects. While the cost of an as-built survey in London may vary depending on the project's complexity, the benefits of having an accurate and comprehensive record of the building's construction process are well worth the investment.
