Value management reviews and analysis are also carried out at various stages of the design process to ensure that all facets of the services systems meet or surpass industry benchmarks established for the project in terms of:
- Acquisition costs
- Operating costs
- Maintenance costs
- Appropriate use of current technology with emphasis on future technology integration
- Sustainability goals
- Impact on existing systems and infrastructure
& Quality Assurance
We are committed to providing the best quality engineering and consulting services. To ensure that we meet the highest of standards, our quality systems have been externally audited for compliance with ISO 9001:2015 quality management system requirements.
We have no issues with the level of documentation and services offered by MDA and would have no hesitation in reusing MDA on the next project.
Services and specifications I found to be very high standard. Your service fees were higher than most others we obtained – in some cases on par with others, however your reputation preceded and was the reason for your selection. The quality of work was then in fitting with the fees I believe.
Very satisfied with the services provided, timeframe in which completed, and high standard of documentation. Staff were courteous and responsive to our needs. We would be pleased to use MDA services again.
