The Firm

About Us

Michael Dequine and Associates, Inc. was established in 2005 through acquisition of the assets of the Spink Corporation. The Spink Corporation was a long established Professional Consulting Services firm in the Sacramento region with a history dating back to 1959. Our office is located in the South Natomas area of Sacramento with close proximity to downtown Sacramento, the Sacramento International Airport, and all major highways through the Sacramento region.

Our staff is comprised of highly skilled professionals with many years of experience in the northern and central California Region. We utilize the latest in computer technology and software to produce high quality field surveys and mapping products. Our software includes Trimble Business Center for GPS data processing as well as Carlson Survey Software with imbedded AutoCad which allow us to produce high quality drawings in .dwg format.

Our survey crews are all members of the Operating Engineers Local Union Number 3. This ensures that our staff are highly skilled and that we can expand staff as necessary to meet project needs. In addition, our field staff are equipped with the latest in GPS technology and conventional surveying equipment.

URS has contracted MDA to provide surveying and mapping services going back as far as 2006. Between then and now, they have provided accurate and timely surveys and mapping on a number of public and private sector projects in a variety of conditions and locations…. MDA is more a member of the “team” than a sub-consultant. MDA takes the time to understand what is needed, communicates throughout their time of service and provides quality surveying products every time. We have used them for a long time and will continue to do so.

Michael Dequine and Associates (MDA) has been assisting EN2 Resources, Inc. since 2010 on the Sacramento Municipal Utility District’s (SMUD) Union Valley Bike Trail Extension Project in El Dorado County... MDA finished the work without problems or delay, and to our complete satisfaction…MDA provided the same quality of service in the second phase of the Project as it did in the first. There is a considerable amount of work remaining on the Project, including surveys and mapping. We fully anticipate that we will continue to receive the same response from MDA as we have in the past.

…Michael Dequine's work has always been excellent and his attention to detail has been meticulous. He has been a true professional and a wonderful resource of historical information. He brings his knowledge, not only of surveying, but also a tremendous network of resources that can only come from his many years of working in Sacramento and for the City of Sacramento. He is solution oriented and a valuable asset to any project team.

Senior Project Manager / City of Sacramento
...In my opinion, the work performed by MD&A in each of these two efforts was thorough and well done in a timely and professional manner. The County of Plumas would not hesitate to consider the selection of Michael Dequine and Associates, Inc. for similar services in the future should the need arise.
