FAQ

  • What are roof deflections? Are they dangerous?

    Deflections are deformations. Any optimally designed structure naturally bends under load. The safe range of deflections is strictly defined in the construction design. When using the roof, it is forbidden to exceed the so-called Limit States. Deflections below the specified range are not dangerous - the structure has the right to bend and move.

  • What buildings can the Sense S-One structural monitoring system be used in?

    The Sense S-One system is applicable in every building with a flat roof: warehouses, production halls, stores, shopping malls, sports facilities or entertainment halls.

  • How are the sensors installed?

    Every alarm system reduces the effects of danger: for example a fire alarm system. Similarly, in the case of using a structural monitoring system, the effects of atmospheric phenomena or aging of the structure are limited. Reducing the risk for the insurer results in the reduction of insurance rates.

  • What is needed to run the Sense S-One system?

    All you need is a power supply from a typical 230V socket and a 2G GSM connection.

  • How often are measurements taken?

    The Sense S-One system has been developed to provide the maximum amount of information about the roof structure, even during sudden phenomena, such as storms. This is why the measurement is carried out automatically every 3 minutes. For specific needs, the measurement can also be performed every few seconds.

  • How will I know that my roof is bending excessively?

    Before the roof bends excessively, the system will send SMS and email notifications about subsequent security levels being exceeded - 50%, 70% and 100%. The email contains a message about the current roof deflection and a link to confirm that the message has been read.

  • Who determines the location of measuring points?

    The number and arrangement of measuring points is extremely important for the monitoring system to provide relevant information. Sense Monitoring has its own know-how in the field of roof structure operation - our experts analyse the project documentation and select the optimal number of sensors in the most reliable places for a given roof. For existing buildings, we also interview the user to learn more about the building's usage history. Sometimes the location of the measuring points is determined by the structural designer.

  • Who is responsible for correctly setting the notification levels?

    The maximum deflection of the roof structure is most often specified in the construction design. During the parameterisation of the system, we always consult the designer - the author of the design of a given building - to confirm the correct values of permissible deflections. If the building has no documentation, we commission a structural survey.

  • What is structural monitoring and why is it needed?

    Structural health monitoring simply means checking specific parameters in a systematic way. This way you can learn how the structure works under the influence of loads, time, atmospheric changes. Observation results provide knowledge about the safe use of the building, necessary services, and preventing the effects of overloads.

  • What notifications are sent by the Sense S-One system?

    The Sense S-One system sends notifications only if the set alarm levels are exceeded. These are short SMS messages and emails with information about the current state of a given sensor.

  • What should I do when I receive a message about the last level being exceeded?

    The manner of responding to notifications about the structure's operation is determined in the internal regulations of each building user. If the permissible roof deflection is exceeded by 80%, it is recommended to clear the snow from the building. Each decision must be additionally supported by knowledge about the mobilisation time of the snow removal team and weather forecasts.

  • How fast can I install the system in my building?

    Installation takes from several hours to several days depending on the size of the building and the complexity of the assembly. For example, for a 10,000 sq.m. building, the installation of 10 sensors will take 2-3 days.

  • Is it justified to install a structural health monitoring system in new buildings?

    New structures are designed optimally due to steel consumption. Therefore, their safe maintenance requires a high technical culture. The Sense S-One system provides information on the operation of the structure from the beginning of the building's lifespan. This allows you to learn how the structure works and react appropriately before critical situations occur. Every alarm system reduces the effects of danger: for example a fire alarm system. Similarly, in the case of a structural monitoring system, the effects of atmospheric phenomena or aging of the structure are limited. Reducing the risk for the insurer results in the reduction of insurance rates.

  • How quickly are system failures removed and how is it done?

    The Sense S-One system has a 99.99% level of availability. Most failures are removed remotely and do not require the user to report them. If a need arises to arrive at the property, the response time is 7 days.

  • What is the lifespan of the laser sensors and the whole system?

    The lifespan of the laser sensors is at least 10 years. The system is additionally covered by a 24-month manufacturer's warranty.

  • Does Sense update the software as new technologies emerge and develop?

    We are the producer of the whole system and we are constantly improving it. Updates take place remotely and free of charge, during the service contract period.
