Assessment of the Condition and Performance of Technical Systems
Technical systems form the backbone of every modern building — from heating, ventilation, and air conditioning (HVAC) to electrical installations, security, fire protection, and IT infrastructure. At First Facility, we consider the assessment of these systems’ condition and performance a key step toward efficient facility management, cost control, and extending equipment lifespan.
Our service provides property owners and facility managers with a precise overview of each system’s current state, helps identify potential weaknesses, and offers actionable insights to improve overall building performance.
What Does the Technical Systems Assessment Include?
Comprehensive Inspection of All Systems: We conduct a systematic evaluation of all technical systems in the building — electrical, HVAC, plumbing and sewage, fire protection, elevators, automation, and BMS systems. Our experts assess equipment condition, operational functionality, safety compliance, and energy efficiency.
Performance and Consumption Analysis: Beyond physical inspections, we analyze operational data such as energy use, failure frequency, emergency response, and overall reliability. Using BMS system insights and manual measurements, we develop a detailed performance profile for each subsystem.
Risk Identification and Weak Point Detection: We uncover potential risks before they become critical — such as aging equipment, poor maintenance practices, system overload, or non-compliance with regulations.
Compliance Assessment: We ensure all technical systems meet legal, technical, and safety standards. This step is especially critical in high-traffic buildings like shopping centers, office complexes, and industrial facilities.
Recommendations for Improvement: Based on our findings, we provide a detailed report with both corrective and preventive suggestions — from small repairs and operational adjustments to full overhauls and component replacement.
How We Assess System Condition and Performance
On-Site Inspections and Technical Checks: Our engineers perform thorough on-site evaluations, including checks of key system components, measurement of operational parameters, and functionality tests of safety and control mechanisms.
Use of Diagnostic Tools: We apply advanced diagnostic technology — such as thermal imaging cameras, energy analyzers, and pressure/flow meters — to detect hidden inefficiencies and issues with greater precision.
Documentation and Maintenance History Analysis: We review technical documentation, blueprints, warranty records, and service logs to build a complete understanding of each system’s background and reliability.
Reporting with Clear Recommendations: Our final report includes system condition ratings, performance analysis, identified risks, and prioritized, actionable recommendations. It gives property owners a clear decision-making framework for investments, maintenance planning, and efficiency improvements.
Strategic Benefits for Property Owners
Cost Reduction through Preventive Measures: Timely assessments reduce the likelihood of costly breakdowns, emergency repairs, and downtime — cutting long-term maintenance costs.
Enhanced Energy Efficiency: We pinpoint systems with high energy usage and provide targeted recommendations that lower utility expenses and support sustainability goals.
Improved Comfort and Safety for Occupants: Efficient, well-maintained systems ensure stable operations and safer environments, increasing tenant satisfaction and user comfort.
Capital Investment Planning: With our detailed reporting, property owners can plan technical upgrades, replacements, and overhauls more accurately, aligning investments with actual system priorities and available budgets.
