Operation & Maintenance


For more than a decade, PBi has provided operation and maintenance services, logistics, engineering and construction and other technical services to the U.S. & AFG governments as well as to the private sector.
PBi’s design and construction experience on the completed projects enable us to offer inclusive operations and maintenance management and services. As most of the O&M works are required for the constructed facilities designed and constructed by a construction firm; that is why, PBi as a construction company can undertake the O&M jobs more efficiently rather than a non-construction firm. This fact has been proven after successful completion of many O&M projects by PBi, some of these projects have been designed and constructed by PBi, and the end users preferred to handover the O&M works of the facilities to the design build contractor.
We deliver operations and maintenance services to the private sector in power generation and distribution, bulk fuel storage, water and wastewater utilities, Road and bridges, highways and other areas where O&M services are required.
On all the projects, we observe the cost-effectiveness to operate and upgrade the facilities to reduce overall life-cycle maintenance costs.
We have specialized experience in operation and maintenance of medium and large facilities including ANA and ANP bases.
Heavy vehicle maintenance and fueling services for the USACE Prime Contractors and the Afghan Government also lays within our scope of services.
Our specialized expertise in O&M is outlined as below:

  • Roads & Highways Maintenance and rehabilitation.
  • Training and O&M manual development for constructed facilities.
  • Campus operations and utilities support services.
  • Building and facilities maintenance and renovations.
  • O&M for electrical utilities and power generation and distribution.
  • Fuel facilities operations and services.
  • Fuel facilities and systems maintenance and repair.
  • Water and wastewater plant operations and maintenance.


PBi believes that facilities operations and maintenance include a broad range of services, competencies, processes, and tools required to ensure the built facility would perform the functions for which it was designed and constructed. PBi’s Operations and maintenance services typically include the day-to-day activities necessary for the building/built structure, its systems and equipment, and occupants/users to perform their intended functions.
Our operations and maintenance approach is combined into the standard term O&M because a facility cannot operate quite efficiently without being maintained; therefore the two are discussed as one.
PBi’s scope of O&M includes the activities, processes, and workflows required to keep the whole built environment as contained in the projects Real Property Inventory of the facilities and their supporting infrastructure, including utility systems, parking lots, roads, drainage structures, Power Generation and Distribution, Waste Water Facilities, Telecommunication and other grounds in a condition to be used to meet their intended function during their life cycle.
These activities based on our O&M policy ,include both planned preventive and predictive maintenance and corrective (repair) maintenance.
Based on our knowledge and understanding , Preventive Maintenance (PM) consists of a series of time-based maintenance requirements that provide a basis for planning, scheduling, and executing scheduled maintenance. Planned Maintenance includes adjusting, lubricating, cleaning, and replacing components. Time intensive Planned Maintenance, such as bearing/seal replacement, would typically be scheduled for regular shutdown periods, Predictive Maintenance attempts to detect the onset of a degradation mechanism with the goal of correcting the degradation before a significant deterioration in the component or equipment occurs.
Our Corrective maintenance strategy asks for a repair necessary to return the equipment to proper functioning condition or service and may be either planned or unplanned.
In all cases, PBi’s O&M strategy requires a knowledgeable, skilled, and well-trained management and technical staff and a well-planned maintenance program. The goals of a comprehensive maintenance program include the following:

Reduce capital repairs
Reduce unscheduled shutdowns and repairs
Extend equipment life, thereby extending facility life.
Realize life-cycle cost savings, and
Provide safe, functional systems and facilities that meet the design intent.
