Western Asphalt Products was a concept in 2011 with the goal of building two emulsified asphalt terminals in western Canada within a two-year timeframe. Each project had over a mile of pipe, new office construction, various acids, emulsifiers, solvents and asphalt cement ranging in temperature up to 400°F. The attention to detail on this project was astonishing as all the piping had to be within millimetres for off site pre-fabrication. Northstar Engineering was selected as the Engineering firm of choice for their advanced 3-D modeling capabilities. The precision technology eliminated costly overruns during construction.

As the owner of the projects I have worked extensively with David and Northstar Engineering over the past two years. David has guided our team through two provincial boiler safety associations, health and safety codes, electrical codes and requirements for importing foreign specialized equipment. The amount of time and labour required to engineer the project was incredible. David and staff frequently went above and beyond making himself available on evenings and weekends to answer questions and complete the projection schedule.

Overall, I have thoroughly enjoyed working with David and Northstar Engineering staff. I felt I had superior support throughout the project. Northstar Engineering consistently added value to procurement suggesting new methods of manufacturing as well as common sense approaches working in the best interest of the client.

I wanted to take this opportunity to thank-you for another successful project completion. Renovations can be challenging and you were able to meet the needs of the project nicely. When challenges arose you and your team were able to respond quickly and with expertise. It was a pleasure working with you and your team again and look forward to the next project.
— Jeremy Sguigna, Lic Tech OAA, Architectural Design Group Inc.
From the start, we have found David to be skilled and honest in his approach to business as well as engineering challenges. He has been consistently accessible and willing to extend extra effort to explain design decisions, assist contractors and provide advice. At critical times during the project, his assistance was invaluable in finding the most suitable solution to the issue at hand. It is a distinct pleasure to recommend Northstar as consultants for mechanical, electrical and plumbing services and I would not hesitate to retain their services again in the future.
— Karen Snyder, Managing Director (Co-Owner), LiquidGym Inc., Ontario, Canada
The work in both projects comprised of demolition, design and reconstruction of the space as per our customer’s needs. The designs, mechanical know how and the timely delivery of the mechanical designs surpassed our expectations and David and his staff were professional in all aspects.

David impressed us with his knowledge of the building code, his attention to detail, progress reporting and inspections and his ability to effectively communicate any changes required to our staff plus to our customers as required.

It is without hesitation that we recommend Northstar Engineering and David Long and his staff.
— George Martellacci, President, Martella Consulting Inc.
As we reflect on 30 years in business, we can honestly say that we have not had the pleasure of working with another mechanical / electrical engineering firm that works as collaboratively on the team to achieve the best design quality. We have always believed “quality” at initial design saves the project time and cost!

Your entire team pays attention to the myriad of small details that make a project successful by actively reviewing all of the design features in advance, allowing us to build it right the first time. You understand that by actively listening to the requirements of the client and building with the strength of all of the team members, we can deliver success with unrivaled professionalism on our projects. We wish you well, and we look forward to many more successful projects in the years to come.

His time spent here was nothing short of excellent and I would highly recommend him for any job. It was a pleasure to work with such a professional company and employees. Any future work I may be doing on my Midland Inn and Suites I would definitely keep Northstar Engineering & Technologies Ltd and David Long in mind.

I have had the pleasure of working closely with David Long, P.Eng., of Northstar Engineering & Technologies Ltd. recently for a high profile Pre-Start Health and Safety review to satisfy Ontario Regulation 851 for Industrial Establishments.

The interaction with David on a personal level, which includes client response, professionalism, and his ability to consider many facets of the project has been excellent and very refreshing. The report provided by Northstar was detailed, logical, and relevant and served our needs as well as our client’s needs. Their dedication to engineering excellence was clearly evident.

I would not hesitate to recommend Northstar Engineering & Technologies Ltd. for engineering services.
— Bart Pasowski, P.Eng., M&E Project Manager, AECON Buildings
I am writing today in support of David Long and the work he and his company have completed for me over the last several years. Since 2007, Northstar has taken on design projects ranging from Kitchen cabinet door pant lines to Aggregate mixing stations. They excel in providing conceptual design, detailed drawings for fabrication, site review, pre-start safety review, final reviews and various other project management functions. These projects have been completed in the $500K CAD range (including capital), and have touched on all aspects of mechanical, structural and electrical design.

David has helped to provide turnkey solutions to problems my organizations have faced. As many organizations no longer have internal engineering support; he has become a key resource for us, one that I also rely on to provide actual help in developing ideas to solve those very problems. He is familiar with relevant technologies, has access to all required engineering disciplines, and is resourceful. Individually, David is passionate about engineering and how he can push his organization further in the pursuit of best practices and new technologies. But most importantly, David is trustworthy, capable and a good communicator.

We have found them knowledgeable and professional with an openness to tailor a solution to our company needs. I would not hesitate to use them in the future and recommend there services to others.
— Francis Peeters, Manufacturing Engineer, Theta TTS, Ontario, Canada
David has very strong professional ethics as shown when dealing with issues arising with customers, suppliers and management.
— R. Marshall, P.Eng., Professional Electrical Engineer, Ontario, Canada
I appreciate the very thorough job you have done, and your patience in reconciling the collection of personalities you have encountered on this job.
