Qatar RAIL Ventilation

MRT

Metro and Rail Ventilation


Underground transport and rail systems become more and more frequent as they allow rapid transit times while transporting a large number of users. The network of high speed trains and also standard rails are more and more transferred to underground tunnels in order to mitigate the environmental impact.
Both applications need ventilation rates. In Metros the influx of a large number of people and the presence of moving trains generate a reduction of oxygen and an increase in heat and pollutant. Mechanical ventilation is then required to achieve the necessary air exchange and grant users of the underground train systems comfortable conditions.
Ventilation systems have a second and even more important purpose. That is to guarantee safety in case of fire emergency. In order to create a safe and clean environment for escaping mechanical ventilation both in tunnels and in the stations is activated. In rails the ventilation of tunnels is mainly dedicated to fire emergencies where it is vital to keep under control the smoke propagation and create safe areas and clear environment for the users.

 

Drilling

Tunnel Drilling Ventilation


Ventilation during tunnel construction is needed so to provide the external air required to dilute the pollutants produced by the machines used during the different stages of the manufacturing. The working squads a safe environment.
Our wide product range ensures you the most suitable solution for ventilation in the construction phase of the tunnel. We can size the systems in accordance with the enforced laws. The product range consists of axial fans single or multi staging to achieve the required system pressure for any tunnel length. High-tensile ventilation ducts, efficient inverters and reliable dedusters complement our system.

 

Road Tunnel

Road Tunnel Ventilation


In road tunnels ventilation rates are needed to dilute the pollutant emissions from vehicles - like Carbon Monoxide (CO), Nitrogen Oxides (NOx) and soot (particles matter) - in order to keep acceptable air quality for the users.
Just as important is controlling the effects of a fire in tunnels. The ventilation system needs to be designed and sized to provide sufficient velocity and direction for controlling the spread of smoke and heat in the event of fire.
The ventilation systems can be configured depending on different key elements such as: length, traffic direction, gradient, flow rates, fire size and scenario etc.
Systemair provides technical expertise for the design of the ventilation systems, supplies state of the art products and gives support for the installation, commissioning and operation of the delivered systems.

Who we are

Quantum Engineering is a trading and contracting company which focuses on finding engineering solutions, environmental and electromechanical, for Qatari industrial-based industries and constructions. It was established in 2013 by His Excellency Sheikh Mohamed Bin Hamad Bin Abdulla Al-Thani together with Mubarak Al Hajri and Naser Elhafy.

Originally it was responsible for the majority of trading activities within the Group including its manufacturing of GI ducts, trading of HVAC equipment and Engineering Divisions. Due to the extraordinary growth experienced by the Group in all its activities, the need for a major restructuring became apparent. New companies were formed in order for them to fully focus on their own individual areas of the market. Today, Quantum Engineering is a Trading and Contracting Company that is also primarily engaged in innovative and sustainable solutions for environment and electromechanical needs of industries and constructions, is still at the heart of Qatar's industrial growth. Its operations although overlapping those of other Group members are normally conducted on a more corporate level working as an intermediary between the Qatar government and its agencies and international companies who wish to have a presence in Qatar.


The streamlined company now consists of four independent divisions, namely:
1.) Recycling Services Division 
2.) Trading Division 
3.) Engineering Division

Key clients include:
• Qatar Rail
• Qatar Foundation
• Qatar Petroleum
• Hamad International Airport

The design and implementation of the Quantum Engineering quality management system has been influenced by Sheikh Mohamed Bin Hamad Bin Abdulla Al Thani in particular business environment and business analysis. In addition, the system has been structured to support the varying needs of the business, its particular objectives, the services it provides, the processes it employs and its size and organizational structure. 
The implementation of the requirements of the ISO 9001:2008 international standard has been used to meet customer and statutory and regulatory requirements applicable to products and services. The implementation and interaction of the system processes are managed to produce the desired process outcome. 
In relation to the International Standard and Quantum Engineering implementation of ISO 9001:2008 the term "product" applies to the product intended for, or required by, a customer or the product realization processes. This applies to any intended output resulting from a product realization processes, including purchasing. 
Where appropriate, statutory and regulatory requirements are also expressed as legal requirements.

Quantum Engineering has established a QMS in order to ensure that the company:


➢ Meets or exceed the requirements and expectations of its customers.
➢ Continuously monitors, measures and improves customer satisfaction.
➢ Continuously monitors, measures and improves its own performance.

Through meeting these objectives, Quantum Engineering seeks to manage the effective implementation of their Waste Recycling and vending services.


The QMS is designed to assist with the identification, interaction, control, monitoring, analysis and improvement of all key business processes. These key processes are managed to ensure:


• Conforming services are delivered.
• Control methodologies are in place and effective.
• Adequate resources are available (including competent personnel).
• Non-conformities are prevented.
• Measurable quality objectives are satisfied.

The effectiveness of the QMS is regularly audited, reviewed and improved in accordance with ISO 9001:2008 and the needs of the business.
