The infrastructure maintenance is a fundamental element in the management of public and private assets. Its correct execution ensures the structural safetythe life cycle optimization and the operating efficiency of the works.
From roads and bridgesto hydraulic, railway and renewable energy installationsIn order to avoid critical failures and optimize the life cycle of each infrastructure, proper maintenance is essential.
At CHM Works and Infrastructures we combine experience and technology to guarantee the integral maintenance of infrastructures. We develop preventive, predictive and corrective plans that optimize the life cycle of each asset and comply with all technical and legal requirements.
Types of Infrastructure Maintenance
Preventive Maintenance
Scheduled actions to anticipate failures and degradations. Includes periodic inspections of asphalt pavements, road signs, building envelopes, electrical installations and PCIas well as air conditioning units. The aim is to minimize the likelihood of failures by means of periodic protocols y technical verification rounds.
Corrective Infrastructure Maintenance
Includes the immediate relief after detection of damage or malfunctions. For example, the repair of cracks in pavementsthe joint sealingthe replacement of defective valves and fittings in supply networks or the renovation of obsolete electrical systems in buildings.
Technical-Legal Infrastructure Maintenance
Oriented to the adaptation of infrastructures to new technical and environmental regulations. Includes the update of energy efficiency installationsthe reinforcement of critical structures according to Eurocodeor the modernization of street lighting systems in compliance with sustainability regulations.
Benefits of Good Maintenance
- Operational SafetyReduces the risk of structural failures and accidents, guaranteeing the integrity of the infrastructures.
- Comfort and User ExperienceImprovements in the quality of service and in the conditions of use, both in roads and buildings.
- Cost OptimizationA well-designed preventive plan minimizes long-term costs and avoids more costly emergency interventions.
- SustainabilityIncreases energy efficiency, reduces resource consumption and contributes to the circular economy.
3. Maintenance in Different Types of Infrastructures
Building .
- Structural and façade overhaulControl of cracks, detachments and deformations.
- Maintenance of facilitiesVerification of electrical, HVAC, air conditioning and plumbing installations.
- Energy efficiency technologiesImplementation of IoT sensors, LED lighting and smart HVAC systems.
Civil Works and Transportation
- Structural inspection of bridges and viaducts: Use of drones and vibration sensors for the early detection of pathologies.
- Road maintenancePavement repair, drainage, horizontal and vertical signage, and slope control.
- Sustainable pavingUse of recycled asphalts and low-emission techniques.
Hydraulic Infrastructures
- Control of sewage and water supply networksRobotic inspection and sensors for leak and blockage detection.
- Revision of dams and reservoirsStructural reinforcements: Supervision of floodgates, flow control and structural reinforcements.
- Remote monitoring systemsEarly warning of loss or deterioration of materials.
Railway Infrastructure
- Maintenance of track and station infrastructuresRepair of rails, overhaul of switches, drainage systems and platforms.
- Tunnel safetyLighting, ventilation and evacuation systems.
- Predictive monitoringTrain and rail wear control by AI and sensors.
Renewable Energies
- Photovoltaic plantsInspection and cleaning of solar panels, revision of inverters and batteries.
- Wind energyWind turbine maintenance, overhaul of blades and electrical systems.
- Remote monitoring systemsReal-time control to maximize production and efficiency.
4. Integrated Asset Management
The asset management is based on the standard ISO 55000which provides a methodology to maximize the value of assets during their life cycle. At CHM we implement Asset Lifecycle Management (ALM) strategies that allow planning and prioritization of maintenance based on the cost, risk and performance analysis.
5. Advanced Technological Tools: CMMS, BIM and SCADA
- CMMS (Computer Aided Maintenance Management)Centralizes and manages work order scheduling, intervention history and document traceability.
- BIM (Building Information Modeling)We integrate BIM in the operation and maintenance phase, facilitating access to technical information and allowing simulations of future scenarios.
- SCADAControl and data acquisition systems for critical infrastructures such as hydraulic networks, electrical substations and treatment plants.
6. Risk Analysis and Contingency Planning
At CHM we develop Risk-Based Maintenance (RBM) Plansprioritizing interventions according to their criticality. This guarantees the business continuity maintenance of key infrastructures such as rail tunnels, urban supply networks o energy infrastructures.
7. Circular Economy and Sustainability in Maintenance
- Recycling of materialsUse of recycled materials in pavements and structures.
- Reuse of componentsRefurbishment of technical equipment.
- Minimization of waste and emissionsApplication of cold paving processes and sustainable rehabilitation.
8. Performance Indicators (KPIs)
CHM monitors and evaluates key indicators such as:
- Operational Availability (OA)
- Mean Time Between Failures (MTBF)
- Mean Time To Repair (MTTR)
- Cost of Maintenance per Asset (CMA)
These KPIs allow analyze the efficiency of the maintenance plan and make adjustments for its continuous optimization.
9. Applicable Technical Standards
Our maintenance procedures comply with:
- ISO 55001Asset management.
- UNE-EN 13306Maintenance terminology.
- ISO 13822Safety assessment of existing structures.
- RD 1627/1997Safety and health on construction sites.
- Structural EurocodesTechnical requirements in structural design and maintenance.
Infrastructure maintenance is not only a necessity, it is also a necessity. strategic investment that ensures the safety, efficiency and sustainability of any asset. At CHM, we integrate technology, experience and environmental commitment in our maintenance programs, guaranteeing the maximum profitability and functionality of the infrastructures throughout their useful life.
