We strongly believe that the key to our company’s success lies in listening to our customers, understanding their needs and providing the most efficient and cost effective solutions.

We provide savings by design by employing Integrated Design process and Workshops.

Today, the Architecture, Engineering and Construction (AEC) industries are moving towards sustainability and Life Cycle Cost (LCC) considerations. We at JACE are committed to promoting sustainable and environmentally conscious designs by incorporating LEED (Leadership in Energy and Environmental Design) green building concepts into all of our projects, respective of a LEED Certification requisition by owners.

We are dedicated to incorporating and utilizing the latest advancements in our field. With members of our team having several years of experience with Building Information Modeling (BIM), we are proficient with the tools and techniques required to complete projects using BIM.


Manufacturing dealings, distributing quality.

Our success as a Mechanical, Electrical, and Plumbing Engineers and consultants depends on our client’s – Architect and Building owners success. It is, therefore, our objective to develop lasting cordial relationships by being their “partner in Success”. We do this by meeting or exceeding their expectations, while maintaining a motivated workforce.


Create. Augment, and sustain.

Improve indoor environment to reduce operating cost of the building and increase workers health, productivity and disposition by improving indoor air quality, lighting and efficient plumbing.


Only our greatest will do.

As building design professionals, we feel that we can never put enough effort, attention, and dedication to getting it done right. We commit ourselves to quality engineering before profit, using best available technologies. Using proven methods and processes (best practices) and employing skilled, competent and motivated workforce and to be honest, just and fair.


High performance, high superiority.

Our senior management employs a hands-on approach to all projects and is committed to providing exemplary service, early in the design phase we take lead in understanding the client’s needs and establish the scope. A dedicated project manager assumes responsibility of progress in the design and achieving project landmark deadlines. Each discipline (Electrical and Mechanical) has a nominated Responsible (Lead) Engineer who is responsible for not only the design and CADD aspect but is also responsible to get the design peer reviewed before issuing for tender.

Our designers realize the need and importance of continuous on-going coordination between disciplines and Architect during design, and that it is paramount in minimizing costly change orders during construction. We produce coordinated, measured and value engineered designs and tender documents.
