In order to develop the technical characteristics of a project, it is necessary for engineers of different disciplines designing while using different software to solve, illustrate the results and draw up plans. Despite the digitization of the design records, the large number of the designs in a project (topographical, architectural, static, electromechanical, etc.), and the changes normally required both during their preparation and during construction, either because of a change in the data from actual measurements or for reasons of coordination and construction, create errors, delays, but also a great deal of confusion in the execution of the projects. In order to improve the quality and cost of projects, it is vital to intervene in the way that digital data from designs are used. There is an immediate need for bidirectional connection and real-time communication to alleviate problems from overlaps or delays in the integration of changes with the aim of speeding up construction, reducing additional costs due to incompatibility of implementation studies and more rapid investigation of changes occurring during construction.
Over the past decade, BIM (Building Information Modeling) which provides a comprehensive digital representation of the physical and functional characteristics of a structure by extracting, updating and modifying information to support and reflect the roles of the project participants, has developed rapidly. Its use extends to all lifecycle phases of the project by supporting services such as cost management, project management, constructability, and operations management.
At this point, it is worth noting that in the United Kingdom, which is considered a pioneer in this field, BIM systems are used for all public projects from 2016. In Greece, it is also expected to be introduced into public projects in the coming years. This sets the need for integrated management, as proposed by this project, all the more urgent.
However, the practice applied to date, combined with the inability of interaction between individual digital design files (from different software companies) and BIM, significantly restricts its use, as for any change relating to individual studies (static, mechanical, energy, etc.) each computer model should be modified and resolved in its own working environment. Only limited software companies have integrated files from different designs (but from the same software) into a common BIM environment that can interact digitally. For this reason, it is evident that creating a dynamic shared communication platform for files exported from different software is essentially the only solution for the real-time integrated management of construction projects, offering a complete package for coordinated and optimal construction.
