We specialize in providing design, engineering and drafting services to industrial, commercial, residential and retails projects, you can ensure your HVAC systems provide the right temperature and humidity control, to guarantee comfort and indoor air quality for the occupants in your building. In business settings, this brings the added benefits of increased productivity and reduced sick leave – you can improve working conditions and increase profits simultaneously. ARA engineers can ensure your system is designed and installed to run efficiently, deliver maximum occupant comfort, and maintain environmentally-friendly standards.

Our HVAC designs also guarantee building code compliance and a quick project approval, as well as energy efficiency. Most energy expenses in a building can be attributed to HVAC installations, and we make sure your electricity and gas bills are minimized without compromising performance.

Designs are reviewed, signed and sealed by a licensed professional mechanical design engineer. This is everything needed for Department of Buildings and Landlord approvals, accurate construction cost bidding, upholding quality workmanship, and a smooth construction process.

Our Services


Architecture is a powerful instrument that has been and will continue to shape the built world around us. It is the tool that has given nations the ability to showcase their strength and identity through monuments. Through architecture, architects can create artifacts that naturally impact our daily lives;


Designing any project, small or large, requires a broad range of knowledge, expertisea and attention to detail. This is a complex process that requires a comprehensive, multi-disciplinary vision of the project. This process involves a sequence of closely related stages that form the outcome of a project.


Team of qualified plumbing engineers is experienced in providing a range of plumbing engineering services for multiple types of plumbing engineering design project to match a variety of service needs based on the specific sector that you need assistance with.



Structures differ in form, proportion and function, however the core engineering elements that are consistent throughout are strength and stability. These components, together, ensure occupants’ safety in any built environment.


Delivering enough power and operating safely are basic requirements for all electrical installations. However, electrical engineers also recommend the use of energy efficiency measures. While these measures may increase the initial cost of your electrical systems,

Sprinkler/ Fire Protection

We make fire protection and life safety a focal point in all designs. When applied early in design, life saving features such as fire sprinklers, detection, fire alarms and mass notification, smoke exhaust, high expansion foam, and clean agent chemical extinguishing systems can allow for cost savings in other areas of construction.
