PQE's Safety Policies :-

  1. Safety & Quality is our first priority.
  2. All Project Staff must Maintain a High Standard of Safety at all times. All matters pertaining to safety must be dealt with promptly. Project Manager to liaise directly with contractor regarding any on-site safety issues and would be directly responsible for the implementation of all safety measures.
  3. To Eliminate Possible Risks during Planning Stage. The objective of early planning is to reduce the risk factors before the project starts. During planning stage, all danger zones must be identified and precautions taken in advance.
  4. To Achieve Consistency in Safety Standards. All project staff, especially the Project Manager must be consistent in maintaining the standard of safety. He must maintain a high standard of safety for all his projects regardless of project nature and duration.

The company's safety record

Why is cleanroom necessary?

In the technological industries such as electrinics, optical and biological industries, the newly developed commodities are manufactured with precise fabrication as a basic process. Both production yield and product quality are, therefore, affected by invisible airborne particles or dust. For example in manufacturing of semiconductors, the design rule of ULSI is now minimized to the line width of submicron. In this case, the size of particle to be eliminated in the cleanroom is smaller than 0.05 µ m, namely, 1/5 ~ 1/10 of the design rule, which means that only a super clean environment can be accepted for its production process.

Also, in food processing, medical or pharmaceuticals, how to control the micro-organism is a key point to maintain the quality, which can be performed by cleanroom.

Cleanroom is defined as "a specially constructed room in which the air supply, air distribution, dust and airborne particle, room pressure, temperature and humidity are environmentally regulated to meet appropriate cleanliness level".

Particle referred here means a particle as small as 1/1000 of human hair in diameter, which is equivalent to 1/100 of the smallest visible limit. These small particles affect production yield and product quality to a great extent. 

Air filters being used in common HVAC system can never collect these particles. Also many factors other than air supply are to be carefully managed to make clean environment condition. Cleanroom is what solves these subjects.

Cleanroom is divided into two kinds by application; one is Industrial Cleanroom and the other Biological Cleanroom. The latter, togetter with cleanroom function, controls contamination density of micro-organism and plays an important role in clinical research and examination, development of medicines, research and improvement of cultivation cycle and plant breeding, etc.

Generally, a high efficient filter is used, and its development has now advanced from 0.3 µ m HEPA Filter (High Efficiency Particulate Air Filter) to ULPA Filter (Ultra Low Penetration Air Filter) which can eliminate 0.1 - 0.2 µ m particles in diameter at an efficiency of 99.999%.


Civil Engineering

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. Civil engineering is the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. 

It is traditionally broken into several sub-disciplines including architectural engineering, environmental engineering, geotechnical engineering, control engineering, structural engineering, earthquake engineering, transportation engineering, forensic engineering,municipal or urban engineering, water resources engineering, materials engineering, wastewater engineering, offshore engineering, facade engineering, quantity surveying, coastal engineering, construction surveying, and construction engineering. 

Civil engineering takes place in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies.


Mechanical Engineering

Mechanical Engineering 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.

The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science,structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided design, andproduct lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others.



Air showers are specialized antechambers which personnel need to pass through before entering cleanrooms in order to decontaminate. This is done so by clearing off dust and dirt particles from bodies of cleanroom personnel to minimize contamination of equipment or products. HEPA filters are generally used in air shower units to filter out particles greater than 0.3 micrometers in size.

There are various possible designs to an air shower unit, for example, single-side shower, double-side shower, three-side shower as well as top shower. Spraying wind speed is around 25 m/s or above through stainless steel nozzles.

As a percentage of the total cost of the modern cleanroom, the cost of an air shower installation is considered minor. In various fields where sterile conditions are critical- for example, life science and biomedical research, pharmaceutical, parenteral drug, microelectronics, aerospace and precision manufacturing—air showers are considered essential equipment.


Due to the requirement of near sterile conditions in cleanrooms, air showers are used to decontaminate by blasting dirt and dust particles off personnel entering the place. The pollutants carried by personnel can affect special equipment. Their use can potentially eliminate contamination and in turn prevent loss of important manufacturing, such as expensive batches of pharmaceutical chemicals and semiconductor wafers. Thus, air showers are common in many factories where sterile conditions are needed.

The “Green Building” is an interdisciplinary theme, where the green building concept includes a multitude of elements, components and procedures which diverge to several subtopics that intertwined to form the green building concept. Generally, the green building is considered to be an environmental component, as the green building materials are manufactured from local eco-sources, i.e. environmentally friendly materials, which are then used to make an eco-construction subject to an eco-design that provides a healthy habitat built on the cultural and architectural heritage in construction while ensuring conservation of natural resources.

This ensures disassembling the building components and materials, after a determined building lifetime, to environmentally friendly materials that can be either re-used or recycled. During their lifecycle, the green buildings minimize the use of resources (energy and water); reduce the harmful impact on the ecology, and provide better indoor environment. Green buildings afford a high level of environmental, economic, and engineering performance. These include energy efficiency and conservation, improved indoor air quality, resource and material efficiency, and occupant's health and productivity.

This study focuses on defining green buildings and elaborating their interaction with the environment, energy, and indoor air quality and ventilation. Furthermore, the present study investigates the green building materials (e.g. biocement, eco-cement and green concrete), green designs, green roofs, and green technologies. Additionally, the present study highlights the green buildings rating systems, the economics of green buildings, and the challenges that face the implementation. Eventually, the interdependency between the green buildings and agriculture has been discussed.
