BIM-based methods for optimizing the design and maintenance of telecommunications infrastructure in data centres

In this dissertation, we presented our research about the improvement methods for design and maintenance of data centres, based on BIM concept. We highlight the main contributions of this dissertation using four theses. First, we introduced our research and the theoretical background of the Structured cabling system in the Section 1. Also novel cabinets family and cable trays design methods was introduced in Section 2.The new special purpose cabinet family enables automatic selection of required equipment and its location in the 'properties' section. This allows for unique filling of each cabinet, eliminating errors in facade diagram creation. All equipment is automatically included in the specification.In Section 3, we described the plugin enables engineers from different systems to use it simultaneously, reduces the time required to search and display collisions by a factor of ten, speeds up the process of generating reports on system intersections, and allows tracking of the history of changes to each individual collision.The aim of this section was to identify the main issues that arise when working on the intersections of engineering systems in the BIM model and developing a plugin.In Section 4, we to demonstrate the concept of a direct connection of BIM from design to operation of a data centre providing a practical example of a temperature and humidity monitoring system.Improving the design and operation stages of data centres leads to increased efficiency and significant cost savings. Crucial to operational efficiency is controlling the temperature and humidity distribution inside data centres. Therefore, finding the better parameters for the temperature and humidity sensor system, including the number and position of sensors, is essential for efficiency improvement.In this case we introduced a solution through the utilization of both CFD analysis and BIM during the design and CFD stages. The conclusions drawn support the necessity of investigating BIM and CFD in tandem.The objective of this research part was to undertake a comprehensive literature review of corridor isolation systems and analysed the use of corridor isolation and identified the optimal method.To determine the method, I carried out BIM of the server room and analysed the required elements, materials, and geometry. Also was used hydrodynamic modelling to identify the distribution of temperature flows. The CFD provides a reliable model that simulates real data centre scenarios.As a demonstration of the differences between hot- and cold-aisle insulation, was analysed the temperature in various vertical and horizontal segments of the server room hall.Finally, in Section 5 we presented possible applications of our main research results. The creation of various add-ons and plug-ins for BIM modelling of technically complex objects such as data centres is an important scientific and engineering experience on the basis of which the performance at all stages of the model's life can be significantly optimised. Also, an important feature of our research is that it was tested on real objects and in case of additional real requests from engineers, we made the necessary adjustments and additions.
