What is a chainman?

Chainmen, also known as chainpersons or survey assistants, are professionals who support land surveyors in the field. Their primary role is to assist with measuring distances and angles, marking survey points, and carrying equipment. Chainmen play a crucial part in ensuring that survey data is collected accurately and efficiently. They typically work outdoors and may use tools such as measuring tapes (chains), stakes, and GPS devices. The position often serves as an entry point into the surveying or construction industry.
