Total stations are the primary survey instrument used in mining surveying. To become a surveyor requires extensive training and EDM Group employs a Professional survey team with considerable experience in areas such as title definition & establishment, feature & level survey and distance measurements for a wide range of projects. Survey existing conditions of the future work site, including topography, existing buildings and infrastructure, and underground infrastructure whenever possible (for example, measuring invert elevations and diameters of sewers at manholes), Stake out lot corners, stake limit of work and stake location of construction trailer (clear of all excavation and construction), Stake out reference points and markers that will guide the construction of new structures, Verify the location of structures during construction, Provide horizontal control on multiple floors, Conduct an As-Built survey: a survey conducted at the end of the construction project to verify that the work authorized was completed to the specifications set on plans, CDM Co-ordinator under the Construction (Design & Management) Regulations 2015, Insurance assessment and claims assistance, Defect investigation and maintenance adviser, Building Inspection to ensure compliance with building regulations, creating new boundaries sanctioned by landowners by way of subdivision plans or plats, and for.

Chapter 4: Theodolite Contents 5.1 Introduction 5.2 Classification 5.3 Components of a Theodolite 5.4 Reading the Circles 5.5 Setting Up a Theodolite. Their types and uses are discussed in this article. The relative positions are also determining by measuring the vertical & horizontal distances and angles accurately by using various Surveying Instruments. EDM stands for Electronic Distance Measurement. Electronic distance measurement (EDM) is a method of determining the length between two points, using phase changes, that occur as electromagnetic energy waves travels from one end of the line to the other end. The Electronic Distance Meter uses electromagnetic waves to measure the distance. For back stations, two plugs are installed in the back, forming a line parallel to the drift. In a plan view, chainage generally increases from left to right, or from the bottom to the top of the plan. An alternative method to transfer elevation is to use water in a transparent hose as the level of the water in the hose at opposite ends will be at the same elevation. With the enlargement of the European community, the profession of the Chartered Building Surveyor is becoming more widely known in other European states, particularly France. Surveying is the phenomenon, which deals with determining the relative positions of various points on or below the earth surfaces. For wall stations, two plugs are installed in opposite walls, forming a line perpendicular to the drift. Most total stations use purpose-built glass prism (surveying) reflectors for the EDM signal. Some models include internal electronic data storage to record distance, horizontal angle, and vertical angle measured, while other models are equipped to write these measurements to an external data collector, such as a hand-held computer.
