PROJECT DESCRIPTION

ANCHOR is an integrated platform capable of holistically assessing the risk and safety and security levels of Genoa Maritime Station’s cruise terminal, which has more than one million passengers/year and thousands of daily transits. The project consortium consists of STAM (lead partner), DGS and La SIA. These players have pooled their know-how to create an integrated solution from three different technology components that today are treated and applied separately and in different contexts. ANCHOR, in fact, boasts the integration of the following three main components:

  • BIM (Building Information Modelling) model, from LA SIA, will be used to create a digital twin functional to the project goals. BIM is generally used for engineering design. In ANCHOR it will be the main visualization component of the platform.
  • Crowd agent model (crowd model), by STAM, simulates the movement, behavior and actions of people taking into account various activities, interactions and external stimuli. Through this model, it will be possible to create scenarios characterized by physical threats (such as attacks) aimed at causing harm to people.
  • RIS (Risk Integrated Service), DGS's Risk Assessment tool, is the calculation engine for assessing the risk of the processes and assets present, providing indications regarding the degree of vulnerability and possible countermeasures to be taken to mitigate the risk.

CONTEXT, STRUCTURE AND OPERATIONAL DETAILS OF THE PROJECT

The ANCHOR platform incorporates the three components introduced in the previous chapters so as to provide the user with a single-entry-point where all information related to the study area can be viewed. The ANCHOR Homepage shows an initial overview of the BIM models on the platform thanks to a special map that indicates the presence of these objects based on their geographical location (latitude and longitude).

From here, the user can access the crowd model and simulate custom scenarios or scenarios generated stochastically by the model.

For viewing BIM and risk analysis data, the user will return to the map on the Homepage and by clicking on the “pins” placed at the location of the site of interest will be able to see the relevant information. These pins will be colored according to the overall risk level calculated by RiS on the site. Clicking on one of the pins will open a menu where summary site information will be previewed including: the associated BIM model, the overall risk level of the site, generic site data. From this menu then the user can access the site details by clicking on the appropriate button.

Site details show different windows and information. The first one that greets the user is about the generic BIM model data, where you can see the site name, location information, data on stakeholders, etc. Another window is dedicated to viewing and navigating the site’s BIM model with which you can interact using tools provided by Autodesk. The results of the risk analysis are shown in the “Risk Analysis” section with information on the highest risk assets, the most applied controls, and all assets present. These can be further explored by clicking on the appropriate “Show More” button through which a window will open showing the controls applied, processes in which the asset is involved, vulnerabilities and potential threats that may affect that asset.

The ANCHOR platform for which represents an innovative application through which the user will have both the ability to manage their assets, visualizing their three-dimensional environment thanks to BIM as well as general information, and consult the vulnerability levels of their sites thanks to the risk analysis that reports useful information on what could be particularly critical solutions that would need security intervention. Overall, the building has an irregular “H”-shaped plan and a footprint of about 33500 square meters, with practicable flat roofs.

LA SIA'S ROLE IN ANCHOR DESIGN: BIM MODELING

BIM modeling of buildings and infrastructure is critical in the design and management activities of buildings and the context they represent. BIM makes it possible to integrate within a single digital model not only the geometric features but also all the intrinsic information of the elements, their georeferencing.

The digital representation for the ANCHOR project started with laser imaging detection and ranging (LiDAR) of the entire Genoa port area to first create a point cloud of the project area. For further detailed modeling of the two crossings of interest, Santa Limbania and Ponte dei Mille, a tripod-mounted laser scanner performed a 360-degree scan.

The survey, which also included the Maritime Station, covered the exterior areas of the building, starting from the west at the height of the pier immediately inside the fenced area and continuing with scans to the opposite side to the east, surveying the terraces, roof, facade, and tunnel. A total of 147 fixed stations were used to perform this mobile mapping system (MMS) contouring.

The result of this survey is a dense cloud representation of colored and georeferenced points that were later used as a reliable basis for BIM. The single BIM model covers an area of about 100,000 m³, which was then divided into four independent macroareas:

The Maritime Station building

The Bridge of the Thousand gap

The passage of St. Limbania

The surrounding port environment
