3. Business Activities

Civil Infrastructure
Aviation Infrastructure
When creating civil infrastructure facilities with a high
concentration of people, special attention is given to
the structural safety.
The
reliability
of
aviation
infrastructure
is
fundamentally determined by the quality of the
technical solutions adopted.
Marine Port Infrastructure
Water Supply and Management
Seaports are the foundation for the development of
the country’s logistics infrastructure.
Utilities are focused on achieving a high level of
automation to increase productivity and ensure
higher quality of treatment.
Oil and Gas Sector
High-Rise and Iconic Buildings
The foundation of safety in the sector is formed
by emergency protection and automation
systems.
Ambitious, technically complex facilities require a
non-standard approach to the development of
technical solutions.
Energy Industry
The sector faces the need to address tasks
related to optimizing the cost of electricity
generation, transmission, and distribution.

Design and Implementation of
Interactive Monitoring Systems
Over 20 years of experience in interactive monitoring for solving the most complex tasks, primarily in
geotechnical applications characterized by incomplete initial soil data. The refined methodology is
applied to the development of monitoring systems for engineering structures of unique buildings and
facilities.
Lakhta Center
Gazprom Arena
The fundamental principle of the
monitoring system is that all
monitoring parameters are
correlated with an interactive
computational model. The model is
an integral part of the monitoring
system and can be adjusted as data
on the facility is accumulated.

Fusion of Monitoring Data and
Computational Analysis
Comparing analytical predictions with measured data
enables the reduction of construction-related risks.
Key Features of a Reliable Monitoring System
• • The system must respond to hazardous processes and
phenomena occurring in structures and their foundations.
• The system must adequately assess the level of danger
based on sensor readings.
• An “alarm” signal must be triggered in a timely manner
when dangerous trends arise, providing sufficient time
for the necessary response.
• The monitoring system must include a decision-making
subsystem, i.e., it must lead to specific actions or
consequences.

Decision-Making Algorithms
Acceptable Condition
Acceptable Condition
A ‘Yellow’ signal from any
sensor group indicates a
deviation from the forecast.
A ‘red’ signal in any
monitoring subsystem
indicates a critical, nonacceptable state.
1. Critical Condition Alert
Notification of the personnel or
organizations responsible for
the structural condition.
3. Temporary suspension
of operation
2. Emergency Structural
Condition Diagnostics
Analysis of structural
performance based on
inverse analysis using the
building’s computational
model.
1.Refinement of the forecast and
recalculation of predicted values.
3. Load reduction,
operational limitations, and
structural reinforcement.
2.Refinement of parameter
variation limits.

System Condition Monitoring
The red threshold is defined by the standards. However,
monitoring with only two states and no intermediate state is
meaningless.

Out-of-Tolerance Values
Monitored Parameter

parameters from the calculated forecast.

Alarm Values
Predicted Value
• It is unacceptable to define structural condition criteria
solely based on the limit state requirements established
by standards.
• To ensure the operability of the monitoring system, the
concept of a ‘predicted parameter value’ must be
introduced.
• A significant deviation from the predicted parameter
value should be considered an alarm signal.
• The computational model must reflect the most probable
state of the structure being analyzed. Design
assumptions that include additional safety margins will
prevent meaningful comparison between calculated
results and actual measurements.
