Explaining Pre-Construction Survey & 4D Survey
Our team has decades of experience when it comes to delivering accurate pre-construction surveys
If proper existing documentation of neighboring buildings is not done before the start of a construction project, it could lead to insurance claims and litigation.
Using the latest in 3D laser scanning technology, Existing Conditions can document the conditions of neighbors at a specific time before construction starts. This will allow you to have a document that you can rely on to show if any damage has taken place.
Some consider this to be a 4D survey – the fourth dimension being time. This is because the reality capture data is tied to that specific moment in time when the surveying occurred. For sites where the passage of time may play a critical factor, having that level of certainty is valuable.
