What Is a Rod Person (Rodman) on a Survey Crew?

A rod person is the crew member who carries and holds the measuring rod at each point being surveyed.

O*NET lists Rodman among the reported job titles for surveying and mapping technicians, the occupation that covers field crew work.

BLS defines surveying and mapping technicians as workers who collect data and make maps of the Earth's surface, assisting surveyors and cartographers and photogrammetrists.

Rodman sits in that occupation's reported title list alongside Survey Technician and Field Surveyor.

The core duty is specific: positioning and holding the vertical rods or targets that instrument operators sight on to measure angles, distances and elevations.

The crew divides the work around that task — one person runs the instrument and records what it measures, and the rod person moves to the points being measured and holds the rod steady while each measurement is taken.

The title is a job, not a license class.

BLS states licensing is not required for surveying and mapping technicians, while the land surveying license is a separate, state-issued credential: BLS notes all 50 states and DC require surveyors to be licensed before providing services to the public.

Our research found no national source that defines the titles, but the sources we checked put rodman and chainman side by side.

O*NET lists Rodman among the reported job titles surveying and mapping technicians report, alongside Survey Technician, Surveying Technician and Field Surveyor.

California's surveyor apprenticeship criteria list Chainman/Rodman as one stage of their program.

Public agencies write their own titles for the work.

Washington State's Transportation Technician 1 — the trainee, beginning level of its Transportation Technician series — lists holding rods and prism poles among its survey duties, and Arkansas DOT's District Surveys Technician class covers field survey work such as staking and layout of highway construction.

On SurveyorHires, rod person, rodman, chainman and survey helper all route to the same listings, so you can search any of the titles.

Which title shows up in a posting is the employer's choice.

Our research checked public class specs rather than a sample of private postings, so we cannot say how often each title appears — read each listing for the duties, not the label.

The day is built around the instrument.

The rod person positions and holds the vertical rods or targets the operator sights on, moving point to point as the crew works down a line.

BLS's task list for the occupation includes visiting sites to record survey measurements, searching for previous survey markers or setting new ones, operating instruments such as electronic distance-measuring equipment, and entering instrument data into computers.

O*NET's top tasks add the rest of the field skill set: setting out and recovering stakes, marks and other monumentation; searching for section corners, property irons or survey points; and adjusting and operating instruments such as prisms, theodolites, EDMs and data collectors.

Back from the field, the work continues: BLS says technicians help process data, including calculating angles and elevations and using CAD software, and O*NET's 2026 task list includes using drone technology to capture aerial images or video for mapping.

The instruments vary by job, too.

BLS notes surveyors use handheld GPS units as well as robotic total stations, instruments that automate positioning of a telescope.

Per BLS, the typical entry-level education for surveying and mapping technicians is a high school diploma or equivalent, with no related work experience required and moderate-term on-the-job training.

That makes the occupation — the rod seat included — open to people starting without field experience or a degree.

BLS describes how the learning works: technicians learn on the job under lead staff, starting with simple tasks such as placing markers and entering data, and eventually help decide where and how to measure the land.

For school, BLS recommends high school math — algebra, geometry and trigonometry — plus coursework in drafting, mechanical drawing and computer science, and notes some employers prefer added education or GIS experience.

O*NET's education survey shows a mix: 33% of respondents said a high school diploma is required and 24% an associate's degree.

O*NET rates the occupation Job Zone Three — medium preparation through vocational training, related on-the-job experience or an associate's degree.

Entry education differs across the neighboring occupations: civil engineering technologists and technicians and drafters typically need an associate's degree, while surveyors and cartographers and photogrammetrists typically need a bachelor's degree.

On licensure: BLS states licensing is not required for surveying and mapping technicians, certification is optional, and employers may prefer candidates with a valid driver's license.

The land surveying license is a different, state-issued credential held by the surveyor.

The public class specs we checked follow BLS's high-school entry level.

Washington's trainee-level Transportation Technician 1 lists high school graduation or a GED as the desirable qualification, and Arkansas DOT's District Surveys Technician class requires a high school diploma equivalent and a valid driver's license.

Private postings were not sampled in our research, so read each listing for its own requirements.

One more structured route exists: O*NET lists four DOL-approved Registered Apprenticeship titles tied to the occupation — Chief of Party, Geodetic Computator, Photogrammetric Technician and Surveyor Assistant Instrument.

It is physically real work.

BLS says fieldwork can involve standing for long periods, walking over harsh terrain and climbing hills with heavy equipment packs, outdoors in all types of weather, and that technicians may travel long distances or temporarily relocate near a survey site.

In O*NET's work-context survey, 44% of surveying and mapping technicians said they work outdoors exposed to all weather every day, 92% said being exact or accurate is extremely important, and 52% reported a typical work week of more than 40 hours.

BLS lists physical stamina among the qualities it calls important for the occupation, alongside communication, decision-making, detail orientation and problem-solving.

BLS also says most surveying and mapping technicians work full time, and some work more than 40 hours per week.

The state DOT class specs put numbers on it.

Arkansas DOT's District Surveys Technician class requires the ability to lift up to 50 pounds, to stand and operate survey equipment for at least two hours without a break, and to traverse rugged terrain.

That class also travels frequently within the district and works in all types of weather and conditions such as noise, dust and fumes.

It is one state DOT example — private employers set their own expectations.

Our research found no BLS wage for rod persons specifically.

The occupation data that covers field crew work is surveying and mapping technicians, SOC 17-3031 — Rodman is one reported title inside it.

In May 2025, that occupation earned a national median of $26.08 an hour, or $54,240 a year, and a mean of $27.89 an hour, or $58,000 a year (BLS OEWS, all industries).

The middle half earned between $45,430 and $66,700 a year.

Read those figures as occupation-wide, not as a rod person starting wage: they cover everyone BLS counts in the occupation — field technicians and mapping technicians alike — at every experience level.

Where a new rod person lands in that spread is set by the employer, the state and the kind of work, and travel assignments, per diem and weather policies vary by employer.

There is no verified national answer to how long each step takes.

Our research found no typical time-in-role before promotion, and the pace is set by the employer and by how quickly you pick up the next skill.

What the sources do describe is the direction of travel.

BLS describes technicians learning on the job under lead staff, starting with simple tasks such as placing markers and entering data, and eventually helping decide where and how to measure the land.

The occupation itself spans the ladder: O*NET's task list includes supervising or coordinating workers engaged in surveying and compiling the information needed to stake construction projects from engineering plans — party-chief-type duties in the same occupation code.

On a crew, the other field seats have names too.

O*NET's task list includes adjusting and operating surveying instruments such as prisms, theodolites, EDMs and data collectors, the core of the instrument operator's seat.

The party chief is the supervising seat — O*NET's task list includes supervising or coordinating workers engaged in surveying, a party-chief-type duty.

Neither seat is a license: the state-issued credential is the surveyor's, and BLS notes all 50 states and DC require surveyors to be licensed before providing services to the public.

The longer run is licensure.

BLS says survey technicians with many years of experience and formal training may be able to become licensed surveyors, with specific requirements varying by state, and that some surveyors begin as surveying technicians and become licensed after many years of experience under a licensed surveyor.

Mapping technicians with more education or experience may advance to cartography or photogrammetry jobs instead.

For structure while you climb, O*NET lists four DOL-approved Registered Apprenticeship titles tied to the occupation, Chief of Party among them.

BLS's industry breakdown shows where the occupation works.

In 2025, 60% of surveying and mapping technician jobs were in architectural, engineering and related services, 11% in local government, 9% in other support services, 4% in utilities and 1% were self-employed.

Local-government technicians may work for highway or planning departments, and many others work for firms providing engineering, surveying and mapping services on contract.

BLS Employment Projections count about 58,800 jobs for the occupation in 2025, self-employed workers included.

From 2025 to 2035, BLS projects 6% growth — faster than the 3% average for all occupations — to 62,200 jobs, with about 6,900 openings a year on average, mostly from the need to replace workers who change occupations or retire.

BLS also notes that although drones and other advances make some survey work more efficient, technicians will still be needed to review and interpret the output of those technologies.
