The modern era of IT has turned to ubiquitous access to all organizations and users. The vision is to provide one “universal access,” i.e. access to all IT services, regardless of geographical location. This is one of the most important aspects of modern IT, and it is turning to the cloud to provide ubiquitous access to users of various organisations including Architecture Engineering and Construction (AEC). 
In BIM ubiquitous access represents the ability for a various cloud services to be widely accessible, for example API connected to Common Data Environment CDE for application of cloud computing technology to BIM Visualization and Manipulation and using cloud services such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform and other cloud providers.
Establishing ubiquitous access for a cloud service, can require support for a range of devices, transport protocols, interfaces, and security technologies. It is much more complex than just using internet as means of communication.
In computing it is referred as a system that is supposed to be available everywhere and at all times, and accessible with any device, in any place and in any format.
There are two variants of ubiquitous access thin – and – thick client – network programs hosted by a provider through an interface, (for example smartphones, tablets, laptops, personal computers and so on)
