Server room designs

Server room and data center projects are among the tasks in which our company specializes. Therefore, we encourage you to read the most important information. This will not only allow you to understand, but also implement a project tailored to your needs.

As with any other construction, the construction of a server room is subject to appropriate legislative and regulatory acts. Each project should be properly prepared and implemented, both from the legal and technological perspective. Investments requiring a building permit require the preparation of a construction design in which the investor specifies the intentions and plans. Everything must comply with both construction law and local regulations, including the local development plan. The construction of a server room or data center is also subject to appropriate regulations. Safety and job security – our employees also provide assistance at this stage of implementation.

Data center projects involve several stages. Due to the significant scope of work and the number of technological solutions used that are required to build a server room, the construction design specifies only the essential elements of the solutions. A detailed scope of work, planning of the installation with an appropriate description, technological requirements, materials used and devices used – these are the tasks of our company, which will present a detailed executive design. In each case, the project will always be developed in accordance with the actual situation and the client’s assumptions.

Before starting the preparation stage of the construction project or the necessary modernizations that are necessary to build a server room for a database center, an analysis of the future user’s needs should be carried out. This will allow you to prepare an appropriate concept that will turn into a detailed design.

The first stage will be to conduct an inventory of current resources and the condition of infrastructure (this applies especially to modernization). This will allow you to determine what elements will be used in a future project. They will be part of the future server room. Inventorying existing IT infrastructure also helps reduce costs.

Data center designs are also closely related to user needs. Therefore, the so-called needs audit. This allows you to create an optimal working environment based on existing solutions and available infrastructure. During a needs audit, our employees analyze not only short-term needs, but also take into account long-term development.

Server room designs must also be based on the technical capabilities of the building and available infrastructure. Much also depends on the resources and type of financing. In a situation where the investment is made from public funds, a concept must be prepared that will be consistent with the announced public tender.

Server room designs end with the preparation of investor cost estimates and the scope of work performed. Detailed description of each stage allows the investor to deepen or acquire knowledge. Thanks to this, the design and previous concept will be even better suited to your needs.

To sum up. The process of preparing for the construction of a server room or data center can be divided into several stages. Inventory of existing IT infrastructure, needs audit, concept development, construction design, executive design and preparation of investor cost estimates.
