Efficiency evaluation of 4D CAD model
Santrauka
4D CAD model topic is poorly analyzed in Lithuanian construction's sector and 4D CAD in practice is hardly used. Number of projects designed by using the 4D CAD model in Lithuania is minimal, only applied to complex multi-story buildings. Efficiency evaluation of 4D CAD model is practically unstudied in Lithuanian construction industry. Purpose of this article – to assess the efficiency of 4D CAD model. For the evaluation of efficiency there was made experiment simulating the construction process. The experiment showed that the use of 4D CAD model, with limited time resources, provide to access almost twice bigger efficiency. 4D information model consists of assumptions speed up to construction process. Also 4D CAD model averagely twice reduces the likelihood of mistakes and helps to detect and remove them quickly.
