The success and growth of Ferris and Flinn, LLC can be attributed to local ownership by hard working professionals that focus on performance and client satisfaction.  Our philosophy is that growth and income are dependent upon quality service and professionalism rather than marketing.

An important aspect of keeping pace with the new and ever evolving technology in engineering and surveying is periodically updating our software.  At Ferris &  Flinn, LLC, we are committed to being innovative  and maintaining our competitiveness in the field of Civil Engineering.   In doing so, we are able to provide the best and most efficient service to our clients.   As a result,  Ferris &  Flinn, LLC has recently migrated from Eagle Point software to Civil 3D software.  Civil 3D software provides an efficient work flow process for our consulting firm.  Ferris & Flinn, LLC pays the maintenance fees to Autodesk to ensure the latest version of the software is deployed.   The use of better engineering and surveying tools and the great integration of a multitude of functionalities reduces the time it takes to do everyday tasks.  Civil 3D software improves the efficacy and accuracy of our work due to its ability to perform countless calculations in a single action.   The implementation of this software creates a positive impact on our productivity, workflow, time schedule and most importantly, reduces cost for our clients.   We look forward to helping all our clients with each and every engineering and surveying need through the use of the best, most effective and most efficient software available.
