Quantity surveying is a branch of civil engineering which deals in the construction industry to offer knowledge on the costs required for construction as well as contracts. Those who work in this field of line are referred to as quantity surveyors. Their primary task is to manage all the costs which relate to construction as well as civil engineering projects. This includes all the necessary calculations; from the initial calculations made before the project is started to the very final figures. Quantity surveyors look to reduce the costs of construction while at the same time enhance the value of the money used with a strict focus on quality and standards. The surveyors have to use certain tools which will ensure that their work is perfect and accurate. These tools include Surveying Magnetic Locators, Electronic Levels as well Abney levels.
1. Surveying Magnetic Locators – The magnetic locators are tools used by the quantity surveyors to locate land survey markers, survey monuments as well as ductile iron water lines. They are also referred to as locating wands and have very high standards when it comes to both reliability and dependability. The magnetic locators used by the surveyors do locate metals which have ferrous in their composition. Such metals include rebar, iron and steel. The level for location is mostly determined by the mass of the object being located. Bigger objects are easier to locate as the magnetised field put out is incredibly vast.
2. Electronic Levels – Electronic levels are used by surveyors to provide accurate shooting grades as well as established elevations. They work through reading a bar code which has been specially made for the graduated grade rod as well as the electronic level, therefore, keeping up with the elevations. The bar code does all the sighting and math required by a quantity surveyor thus providing very accurate results. The electronic levels encompass a great range of construction applications due to their automatic determination of delta height. Once the surveyor feeds in their benchmark, the tool can measure both your back and front sights displaying the results instantly. Such a tool takes away the instances of misreading as well as human errors when reading the rod measurements.
3. Abney Levels – Quantity surveyors also do require good topographic Abney levels to complete their tasks successfully. The tool is used in land surveying and contains a movable bubble level which is connected to a pointing arm, a protractor scale as well as a fixed sighting tube. When the topographic Abney level is used correctly, it offers accurate results which can lead to better interpretation by the quantity surveyors. They are used to provide degree measurements, topographic elevation, percent of grade as well as the chain correction.
