Land Surveying

Since the inception of the firm, TWM has provided professional land surveying and support services for the planning, design and construction of engineering and architectural projects. Land surveying has been evolving as quickly as any other industry. As technology has jumped forward every few years, the equipment and instrumentation used by surveyors has jumped forward as well. Early surveyors were responsible for creating, establishing, and recreating boundary lines for everything from a tract of land as tiny as a parcel in a small town, to larger counties, states, and even entire countries. Regardless of whether new or old technology is being used, professional land surveyors differentiate themselves from other related professions by being expert measurers. At TWM we are constantly updating the technology and equipment we use so we can effectively speed up the process and take the precision of this craft to ever increasing levels.

Our expertise includes innumerable boundary, ALTA, right-of-way, topographic, construction and engineering surveys.  While TWM has used conventional methods, today the firm relies on state-of-the-art equipment, including robotic total stations and GPS technology, to provide fast, accurate data.

We also offer 3D laser scanning services – allowing us to collect millions of points in a short amount of time.  The resulting output is a detailed 3D model of the survey area that can be exported to traditional CAD software for analysis and rendering – further proof of our commitment to the latest technology.

Our field surveying is supported by TWM’s technical staff, using high-end computer work stations running AutoCAD Land Desktop, AutoCAD Civil 3D and MicroStation / Geopak to process, calculate and prepare boundary and topographic survey plats and descriptions, or to establish the basis for a design project.

TWM has the in-house resources to provide multiple, fully-equipped survey crews matched to the project’s needs.  Our focus is always on being responsive to those needs and the client’s schedule with exceptional service at a fair price.
