Building and construction surveying or structure surveying (otherwise referred to as "staking", "stake-out", "lay-out", "setting-out" or "BS") is to stake out referral points and markers that will direct the building of brand-new structures such as roads or structures. These markers are typically staked out according to a suitable coordinate system chosen for the task.

(c. 2500 BC) recommends that the monolith was set out by prehistoric surveyors using peg and rope geometry. Modern innovation advanced surveying's precision and effectiveness.

This innovation could only account for distance and not elevation. Present innovation utilizes the International Positioning System (GPS) that can determine the range from point A to point B as well as distinctions in elevation.

During building surveying, the surveyor will typically have to convert from geodesic coordinates to the coordinate system used for that job. - 1 chain is equal to 66 feet or 100 links) will be developed, frequently to correspond with the centre line of the road or pipeline.

Offset is said to be "left" or "right" relative to someone standing on the chainage line who is looking in the direction of increasing chainage. Plans would typically reveal strategy views (viewed from above), profile views (a "transparent" area view collapsing all section views of the roadway parallel to the chainage) or cross-section views (a "real" section view perpendicular to the chainage).

Profiles are shown with the chainage increasing from left to right, and cross-sections are shown as if the audience is searching in the direction of increasing chainage (so that the "left" offset is to the left and the "right" offset is to the right). "Chainage" may likewise be referred to as "Station".

The grids may be recognized alphabetically in one direction, and numerically in the other instructions (as in a plan). The grids are usually however not always perpendicular, and are frequently however not always evenly spaced. Floorings and basement levels are likewise numbered. Structures, equipment or architectural information may be found in referral to the flooring and the nearest intersection of the approximate axes.

The method is called localized grid. This approach utilizes the strategy structure grids as their own ordinates. A point of beginning is developed at the southwest cross grid. IE [N1000. 000, E3000. 000] The grids are combined heading north and east to make each line its own ordinate. Equipment and strategies utilized in construction surveying [edit] Surveying equipment, such as levels and theodolites, are utilized for accurate measurement of angular discrepancy, horizontal, vertical and slope distances.
