Simple chain surveys have a lot of potential for errors, which may be due to different chain positions. Failure to pull the chain connection properly results in inaccurate data. In addition, chain surveying can lead to errors in chain reading. Construction delays are one of the biggest issues facing the construction industry and affecting delivery in terms of time, budget and the required quality. After a brief review of the basic definitions on tensors, the Heigenvalue problem and the Zeigenvalue problem for tensors are studied separately. The measurement of this linear horizontal distance between two points on the earth surface is known as linear measurement. These are those which remain after mistakes and systematic errors have been eliminated and are caused by the combination of errors beyond the ability of the observer to control.
