CIVIL WORKS Civil Engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings.

PLUMBING WORKS is any system that conveys fluids for a wide range of applications. Heating and cooling, waste removal, and potable water delivery are among the most common uses for plumbing; however, plumbing is not limited to these applications. Plumbing utilizes pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.

MECHANICAL WORKS is the discipline that applies the principles of engineering, physics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery. It is one of the oldest and broadest of the engineering disciplines.

ELECTRICAL WORKS is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the later half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor, and later the integrated circuit, brought down the cost of electronics to the point they can be used in almost any household object.

AIR-CONDITIONING (often referred to as AC, A.C., or A/C) is the process of removing heat from a confined space, thus cooling the air, and removing humidity. Air conditioning can be used in both domestic and commercial environments. This process is used to achieve a more comfortable interior environment, typically for humans or animals; however, air conditioning is also used to cool/dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and even to display and store artwork.

FIRE PROTECTION is the study and practice of mitigating the unwanted effects of potentially destructive fires. It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. In structures, be they land-based, offshore or even ships, the owners and operators are responsible to maintain their facilities in accordance with a design-basis that is rooted in laws, including the local building code and fire code, which are enforced by the Authority Having Jurisdiction.

HYDRANT SYSTEM is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection.

MEDICAL GAS PIPELINE systems in hospitals, and most other healthcare facilities, are essential for supplying piped oxygen, nitrous oxide, nitrogen/surgical air, carbon dioxide, oxygen/nitrous oxide 50/50, medical vacuum, anaesthetic gas scavenge/waste anesthetic gas disposal and medical air to various parts of the facility. Source equipment systems are monitored by central/source alarm systems, at the point of supply with multiplexed repeater alarms throughout the facility and for monitoring high and low gas pressure in particular areas such as general ward, operating theatres, ICU/ITU/CCU/NICU, recovery, major treatment rooms, etc. Equipment is connected to the medical gas supply system via station outlets. For emergency gas control area zone service valves are installed in order to prevent contaminated gas going to patient or to stop gas flowing to an area in the event of fire. Valves are positioned at the entrance to all departments and can be accessed via emergency pull out windows.

CONTRACTOR / SUPPLIER managing of outsourced work performed for an individual company. Contractor management implements a system that manages contractors' health and safety information, insurance information, training programs and specific documents that pertain to the contractor and the owner client.
