Heating, ventilation, and air conditioning (HVAC)[1] is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

Fire hydrant installation consists of a system of pipe work connected directly to the water supply main to provide water to every hydrant outlet and is intended to provide water for the firemen to fight a fire. The water is discharged into the fire engine form which it is then pumped and sprayed over fire.

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid.

Five-hundred kilovolt (500 kV) Three-phase electric power Transmission Lines at Grand Coulee Dam. Four circuits are shown. Two additional circuits are obscured by trees on the far right. The entire 8089 MW nameplate generation capacity of the dam is accommodated by these six circuits.

Lt- low tension line can be considered as the line that has an operating voltage till 1000 volt which is 1Kv. This is the 230V and 440V in our household so it is the local distribution line. Through the low tension or low voltage line we are receiving power to our home. Low tension lines are more susceptible to faults because it is connected Industrial power and control work- in this system we provide all electrical work like that cable laying to IOs cheking

We are dedicated to providing comprehensive piping fabrication and installation services across various industries. Our expertise spans a wide range of piping systems, including oil piping fabrication, Utility piping, gas piping, steam and boiler piping. We excel in the fabrication and installation of PPR (Polypropylene Piping) and PPH (Polypropylene Homopolymer Piping) pipes, known for their exceptional chemical resistance and durability. We ensure each project is executed with precision, adhering to the highest standards of safety and quality, to deliver reliable and efficient piping solutions tailored to your specific needs.

In structural engineering, a pre-engineered building (PEB) is designed by a PEB supplier or PEB manufacturer with a single design to be fabricated using various materials and methods to satisfy a wide range of structural and aesthetic design requirements. This is contrasted with a building built to a design that was created specifically for that building.
