Mechanical works

Mechanical works are a large system which include Plumbing and Sanitary - P&S, Water and Waste Water Treament,  Hot water - Steam boiler. An another part of Machanical system compose Fire Fighting system, Refueling system, LPG system and Compressed Air.

Any building service using machines. They include plumbing, elevators, escalators, and heating and air-conditioning systems. The introduction of mechanization in buildings in the early 20th century brought about major adjustments; the new equipment demanded floor space, and the design team began to include electrical and HVAC (heating, ventilating, and air-conditioning) engineers. Heating and cooling changed dramatically. Modern buildings, with their large heat gains, turned central heating into little more than a supplement. Heat removal is a much more serious burden, especially in warm weather. The roofs of high-rises are occupied by cooling towers and mechanical penthouses; entire floors are often dedicated to the containment of blowers, compressors, water chillers, boilers, pumps, and generators.


All kinds of piping ( Steel concrete, fiberglass, PVC etc…) works for: 

  • Water distribution and waste water diposal.
  • Installation of Pumps
  • Installation Surge Vessel and Surge Tank
  • Installation of SVP Compressor Unit
  • Frabrication and Installation of Pipes
  • Installation of Wall Ducts of Drain Stations
  • Installation of Butterly Valves, Platform and Ladder of the Vessel.

Water distribution systems consist of an interconnected series of components. They include:

  • Pipes
  • Storage facilities
  • Components that convey drinking water

Water distribution systems meet fire protection needs for:

  • Cities
  • Homes
  • Schools
  • Hospitals
  • Businesses
  • Industries
  • Other facilities

Public water systems depend on distribution systems to provide an uninterrupted supply of pressurized safe drinking water to all consumers. Distribution system mains carry water from either:

  • The treatment plant to the consumer; or
  • The source to the consumer when treatment is absent.

Distribution systems span almost one million miles in the United States. They represent the vast majority of physical infrastructure for water supplies. Distribution system wear and tear can pose intermittent or persistent health risks.


New pipes are added to distribution systems as development occurs. The additions result in a wide variation in:

  • Pipe sizes
  • Materials
  • Methods of construction
  • Age within individual distribution systems and across the nation

As these systems age, deterioration can occur due to corrosion, materials erosion, and external pressures. Deteriorating water distribution systems can lead to:

  • Breaches in pipes and storage facilities
  • Intrusion due to water pressure fluctuation
  • Main breaks

Wastewater treatment is a process used to convert wastewater - which is water no longer needed or suitable for its most recent use - into an effluent that can be either returned to the water cycle with minimal environmental issues or reused. The latter is called water reclamation and implies avoidance of disposal by use of treated wastewater effluent for various purposes. Treatment means removing impurities from water being treated; and some methods of treatment are applicable to both water and wastewate

     The treatment of wastewater belongs to the overarching field of Public Works

- Environmental, with the management of human waste, solid waste, sewage treatment, stormwater (drainage) management, and water treatment. By-products from wastewater treatment plants, such as screenings, grit and sewage sludge may also be treated in a wastewater treatment plant. If the wastewater is predominantly from municipal sources (households and small industries) it is called sewage and its treatment is called sewage treatment.

1. Overall :

Fire Suppression systems are governed by the codes under the NFPA. Fire Suppression Systems are commonly used on heavy power equipment. Suppression systems use a combination of dry chemicals and/or wet agents to suppress equipment fires. Suppression systems have become a necessity to several industries as they help control damage and loss to equipment. Common means of detection are through heat sensors, wiring, or manual detection (depending on system selection).

There are many kinds of Fire protection. We specialize on some domains: 

Active fire protection

  • Fire Sprinkler
  • Fire alarm
  • Fire alarm system
  • Fire alarm control panel
  • Fire detection
  • Manual call point
  • False alarm
  • Sprinkler Systems
  • Smoke Alarm

2. Classifying fires

Fire protection is appropriate for any given situation, it is important to assess the types of fire hazard that may be faced.Some jurisdictions operate systems of classifying fires using code letters. Whilst these may agree on some classifications: 

  • Fires that involve flammable solids such as wood, cloth, rubber, paper, and some types of plastics.
  • Fires that involve flammable liquids or liquefiable solids such as petrol/gasoline, oil, paint, some waxes & plastics, but not cooking fats or oils
  • Fires that involve flammable gases, such as natural gas, hydrogen, propane, butane
  • Fires that involve combustible metals, such as sodium, magnesium, and potassium
  • Fires that involve any of the materials found in Class A and B fires, but with the introduction of an electrical appliances, wiring, or other electrically energized objects in the vicinity of the fire, with a resultant electrical shock risk if a conductive agent is used to control the fire.
  • Fires involving cooking fats and oils. The high temperature of the oils when on fire far exceeds that of other flammable liquids making normal extinguishing agents ineffective.

3. Fire sprinkler system:

A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price. Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings completely protected by fire sprinkler systems, over 96% of fires were controlled by fire sprinklers alone.

4. FM200 system: Many fire suppression systems can cause major damage to – and even destroy – the very things they are supposed to protect. You're looking to avoid damage – not cause it. You're looking to reduce downtime – not lengthen it. You want a fire suppression system that deploys quickly and cleanly and won't leave behind oily residue, particulate, or water. FM-200™ fire suppressant stops fires fast. When you consider the potentially devastating environmental effects of an uncontrolled fire, it's easy to see that an FM-200™ system is an important part of an environmentally responsible fire suppression solution.
