I am a civil engineer and do architectural/civil/structural drafting on the side. I believe that my background in engineering and construction management combined with fifteen years of work experience have provided me the required skills to be an effective freelancer for your project. I am also an accomplished and responsible CAD Draftsman with a stellar record of client satisfaction. Vast and deep knowledge of CAD and Revit drafting software and techniques.

I am a civil engineer experienced in land development. I own a small engineering firm based out of Minnesota. Whether your project is small or large, I can help you get it across the finish line. I have full access to civil engineering and hydrologic analysis software. I can create site plans, grading/erosion control plans, utility plans, SWPPP's, signed construction documents (if it is in MN, ND, or WI), perform earthwork analysis, create reports, code review, feasibility studies, photometric plans, and many other documents relating to land development.

Licensed Civil Engineer (PE), CAD Technician Civil Engineering is my main service. This includes civil site design and planning (subdivisions, residential, commercial sites, municipal, developments). I also perform a variety of services with storm water management erosion control plans, stormwater management plans, storm water modeling, flood analysis, and watershed determination. I also can assist with CAD drafting projects, HydroCAD modeling, and building permits. I have worked on more than 100+ projects throughout the United States in my career. Most of these projects being located in MN, SD, TX, CA, FL, NY, and GA. I am currently working as a Licensed Civil Engineer on residential, commercial, and industrial sites with 8 years of experience. I am mostly familiar with AutoCAD Civil 3D, ArcGIS, HydroCAD, and Trimble Business Center software. As far as my work in Civil 3D goes. I am very familiar with the standard tools and features in C3D (Topo Points, Surfaces, Feature Lines, Alignments, Corridors and Profiles, Pipe Neworks). A typical project workflow for me involves: meeting with the client and discussing the project. Starting with a simple site plan to get an idea of what we are looking at, and from there using existing conditions/surveys to complete the design (site, grading, drainage, utility, and storm water management plans). I generally like to meet with clients on a weekly or as needed basis to coordinate changes and answer questions. MY Services : -Subdivision Design & Layout -Residential site plan and layout -Plan set creation (Site, Grading, Utility, Drainage, Plan and Profile, SWPPP, etc) -Project Take-Off & Quantity Estimation -CAD Drafting -2D Floor Plan (Building Permits) -Storm water management (SWPPPs, SWEC Plans, Storm water modeling reports, flood analysis) -GIS-Remote Sensing, Google Earth I have included several examples of my work on my profile, but if you are looking for a specific type of project or want things to look different please reach out to discuss and I can provide more examples if needed. Thanks for your time.
