What is Construction Maintenance Engineers Job Description ?

Job Description

Most large office buildings, malls, warehouses, and other commercial facilities have extensive heating, ventilation, and air-conditioning systems that keep them comfortable all year long. Industrial plants often have additional facilities to provide electrical power, steam, or other services. Stationary engineers and boiler operators control and maintain these systems, which include boilers, air-conditioning and refrigeration equipment, diesel engines, turbines, generators, pumps, condensers, and compressors. The equipment that stationary engineers and boiler operators control is similar to equipment operated by locomotive or marine engineers, except that it is used to generate heat or electricity, rather than to move a train or ship.

Stationary engineers and boiler operators start up, regulate, repair, and shut down equipment. They ensure that the equipment operates safely, economically, and within established limits by monitoring meters, gauges, and computerized controls. Stationary engineers and boiler operators control equipment manually in many older buildings and, if necessary, make adjustments. They watch and listen to machinery and routinely check safety devices, identifying and correcting any trouble that develops.

In newer buildings, stationary engineers typically use computers to operate the mechanical, electrical, and fire safety systems. They monitor, adjust, and diagnose these systems from a central location, using a computer linked into the buildings communications network.

Routine maintenance is a regular part of the work of stationary engineers and boiler operators. Engineers use hand and power tools to perform maintenance and repairs ranging from a complete overhaul to replacing defective valves, gaskets, or bearings. They lubricate moving parts, replace filters, and remove soot and corrosion that can reduce the boilers operating efficiency. They also test the water in the boiler and add chemicals to prevent corrosion and harmful deposits. In most facilities, stationary engineers are responsible for the maintenance and balancing of air systems, as well as hydronic systems that heat or cool buildings by circulating fluid (such as water or water vapor) in a closed system of pipes. They may check the air quality of the ventilation system and make adjustments to keep the operation of the boiler within mandated guidelines. Servicing, troubleshooting, repairing, and monitoring modern systems all require the use of sophisticated electrical and electronic test equipment. Additionally, many stationary engineers perform other maintenance duties, such as carpentry, plumbing, locksmithing, and electrical repairs.
Stationary engineers and boiler operators keep a record of relevant events and facts concerning the operation and maintenance of the equipment. When working with steam boilers, for example, stationary engineers and boiler operators observe, control, and record steam pressure, temperature, water level, chemistry, power output, fuel consumption, and emissions from the boiler. They also note the date and nature of all maintenance and repairs.

In a large building or industrial plant, a senior stationary engineer may be in charge of all mechanical systems in the building and may supervise a team of assistant stationary engineers, turbine operators, boiler tenders, and air-conditioning and refrigeration operators and mechanics. In a small building or industrial plant, there may be only one stationary engineer.
