Over two-thirds of New York City's greenhouse gas emissions come from buildings. Failure to meet Article 320 requirements may result in costly violations. Mechanical systems are a major driver of building energy use and greenhouse gas emissions. Owners must report annual emissions, obtain RDP certification, and maintain supporting documentation. Learn more about Article 320.
PRETECT can help compile the mechanical system data and supporting documentation needed for Local Law 97 reporting. We use advanced vibration analysis and video-based technologies to evaluate and document mechanical systems condition, faults, and performance.
This standard covers performance requirements for emergency and standby power systems providing an alternate source of electrical power in buildings and facilities. Vibration analysis is recommended by many OEMs and supports NFPA 110's focus on generator reliability. PRETECT combines vibration analysis and Motion Amplification® when testing engines and generators. See our generator case study: GENERATOR TESTING
It's a non-contact and video-based Vibration Analysis and Fault Visualization service that combines high-speed cameras, patented vibration visualization technology, software processing algorithms, analysis and reporting. We process and analyze the vibration data, and videos are amplified to visually show you vibration faults.
Traditional vibration analysis using data collectors and single-point accelerometers can narrow down a fault to an area. With Motion Amplification®, we use the camera's 2.3 million virtual sensors to visually show you a fault down to a specific location, including loose anchor bolts, cracked mounting bases, misalignments, and many other fault types.

Vibration analysis (also called machine condition monitoring, machinery diagnostics, predictive maintenance testing, and rotating equipment analysis) is a predictive maintenance technique that measures machine vibration to detect developing mechanical problems before they lead to equipment failure or unscheduled downtime. By monitoring FFT spectra, waveform plots, phase data, and vibration trends over time, facility maintenance managers can schedule repairs before failures occur, improving reliability and reducing maintenance costs. Vibration analysis helps identify bearing failures, shaft misalignment, rotor imbalance, mechanical looseness, resonance, belt defects, gear wear and coupling issues.
Vibration analysis uses sensors mounted on equipment to measure vibration levels and frequencies. The data is analyzed to identify specific mechanical faults based on characteristic vibration patterns. Experienced PRETECT analysts diagnose data to determine both the severity and probable cause of machinery problems.
The frequency of vibration analysis depends on equipment criticality, operating conditions, and failure history. Critical assets may require continuous monitoring or monthly inspections, while less critical equipment may only need quarterly or semiannual testing. Facilities that trend vibration data over time can detect gradual deterioration and schedule maintenance before failures occur.
Unlike reactive maintenance, predictive maintenance focuses on monitoring equipment health rather than waiting for failures to occur. By identifying problems early, facilities can schedule repairs during planned outages rather than responding to unexpected breakdowns.
PdM Services provided by PRETECT include:
Preventive maintenance (PM) is time-based maintenance performed on a fixed schedule regardless of equipment condition, while predictive maintenance (PdM) uses data-driven technologies to determine when maintenance is actually needed. Most modern facilities in NYC combine both strategies to maximize equipment reliability.
Replacing equipment without understanding why it failed often results in repeated failures. Root cause analysis identifies the underlying mechanical, structural, or operational issues. Root cause analysis combines multiple diagnostic technologies to determine why failures occur, why shortened equipment life continues to occur, and recommend permanent corrective actions.
Increasing vibration, abnormal noise, rising temperatures, excessive movement, lubricant contamination, and declining performance are among the earliest indicators of developing machine failure and wear. Routine condition monitoring allows maintenance teams to detect these warning signs before equipment fails and causes downtime.
Most machine vibrations are caused by imbalance, misalignment, bearing defects, mechanical looseness, resonance, soft foot, belt issues, electrical problems, or improper installation. Accurately identifying the true cause often requires multiple diagnostic technologies, including vibration analysis, Motion Amplification®, and root cause analysis.
Elevator hoist vibration can result in poor ride quality, passenger complaints, premature wear, and increased maintenance costs. Common causes include worn bearings, motor problems, sheave defects, rail alignment issues, or structural resonance. PRETECT uses vibration analysis and Motion Amplification® to identify the root cause of elevator vibration so repairs can be targeted accurately, reducing unplanned shutdowns and improving passenger comfort and system reliability. See our elevator hoist case study: ELEVATOR HOIST
Commercial HVAC systems contain multiple rotating components that must remain properly balanced and aligned. Identifying the true cause requires more than simply measuring vibration levels. PRETECT often combines advanced vibration analysis, Motion Amplification®, laser alignment, and root cause analysis to develop effective long-term solutions. Common causes include fan imbalance, motor misalignment, loose mounting hardware, worn bearings, belt problems, structural resonance, improper VFD programming, damaged fan blades, weak structural supports and pipe strain. See our air handling unit case study: AIR HANDLING UNIT
Generators play a critical role in maintaining power during outages, making reliability essential. Excessive vibration may indicate imbalance, misalignment, loose components, bearing wear, or foundation problems that can lead to unexpected failures. PRETECT performs vibration testing and Motion Amplification® to detect developing issues early, helping facility managers improve reliability, extend equipment life, reduce emergency repairs, and ensure generators are ready when they're needed most. See our generator case study: GENERATOR TESTING
Motor vibration is typically caused by imbalance, shaft misalignment, bearing defects, electrical issues, soft foot, resonance, or installation problems. Routine vibration analysis and Motion Amplification® can identify these issues before they result in costly failures.
Pump vibration is commonly caused by cavitation, imbalance, misalignment, bearing wear, hydraulic instability, pipe strain, or improper installation. Accurate diagnosis often requires combining vibration analysis with hydraulic assessment, Motion Amplification®, and precision alignment to identify the true source of the problem. See our pump case study: PUMP
Excessive vibration in industrial fans and blowers is commonly caused by rotor imbalance, misalignment, worn bearings, damaged fan blades, belt issues, structural resonance, or improper installation. If left uncorrected, excessive vibration can lead to premature equipment failure, increased energy consumption, and unplanned downtime. Fan vibration should never be ignored. Routine vibration analysis, Motion Amplification®, and precision laser alignment can identify developing issues before they result in catastrophic failure.
Premature bearing failures are usually symptoms of another underlying problem rather than defects in the bearings themselves. Simply replacing repeated bearing failures without correcting the root cause often results in repeated failures. Root cause analysis helps identify why bearings continue to fail and how to prevent future problems. See our bearing case study: BONE DRY BEARINGS
Electric motors typically fail because of excessive overheating caused by overload, poor ventilation, electrical imbalance, excessive vibration, misalignment, or bearing failures. Condition monitoring allows many motor problems to be detected months before complete failure.
Mechanical seals typically fail because of shaft misalignment, excessive vibration, cavitation, pipe strain, improper installation, or operating conditions outside the pump's design limits. Rather than simply replacing seals, organizations should identify the underlying mechanical issue causing repeated failures. Combining vibration analysis, laser alignment, Motion Amplification®, and hydraulic evaluation often reveals the true root cause and significantly extends seal life.
AI and data centers depend on reliable cooling systems and backup power. Vibration analysis and Motion Amplification® identify developing mechanical problems before they affect mission-critical equipment. Routine testing improves reliability while reducing emergency maintenance. For more information, download Comprehensive Preventive Maintenance Services for Data Centers.
HVAC vibration in New York City high-rise buildings is often caused by structural flexibility, rooftop wind loading, aging equipment, improper isolation, pipe strain, resonance, and deferred maintenance. Motion Amplification® is especially valuable because engineers can visually observe building movement while equipment operates.
Tenant vibration complaints often result from HVAC equipment, excessive noise complaints, structural resonance, piping movement, or rooftop mechanical systems. Proper diagnostic testing identifies the source before unnecessary repairs are made.

Vibration isolators are designed to prevent vibration from HVAC equipment, pumps, cooling towers, and generators from being transmitted into a building. Over time, isolators can sag, deteriorate, become overloaded, or be installed incorrectly. Failed isolators can lead to excessive vibration, noise complaints, equipment stress, and even structural damage. PRETECT evaluates isolation systems, identifies failed or improperly adjusted isolators, and makes recommendations to restore proper equipment support and vibration control. See case study: ISOLATORS
