“Ingenieria Dennis” presented us with an innovative and steadfast solution in response to the 2010 Earthquake that struck Mexicali, BC. We needed a company that had great knowledge and experience in planning, designing, supervising, implementing and executing the hydraulic workforce necessary to re-establish the services in the agriculturally affected areas in the city.


Ingenieria Dennis, as the lead company in the project, was a company that upheld and completed all deadlines in a timely and professional manner. Moreover, they always exceeded expectations and went above and beyond in every project that I have had the opportunity to work alongside them with.

We are grateful for their personal attention and exemplary abilities to meet deadlines. Their experience, attention detail and specialization in their industry makes them a leader in all areas."
