What is Surveying?

surveying-equipment-hire

Survey equipment refers to a variety of tools used to conduct surveying, which is the mapping and measurement of a certain environment (often a construction site) using specialised technology, equipment and mathematics.

These tools include surveying instrument tripods, surveyors safety vests, planimeters, surveying bipods, levels, land surveying markers, marking machines, GPS equipment, surveying prisms, survey drones, land surveying rods, transits, stakes, grade rods and much more. Surveying contractors work out in the field, using technology like GPS, taking photos and making computations. They then use sophisticated software to process survey data and draft up maps, plans and survey reports.

Our directory offers a variety of qualified survey equipment suppliers throughout major cities like Brisbane, Sydney, Melbourne, Adelaide, Perth, Canberra, Hobart, and Darwin, along with hundreds of regional centres across Australia.

How does surveying equipment work?

Surveying was originally developed to help people determine the shape and size of pieces of land through the use of mathematical measurements. These days, construction surveys are performed before any large-scale construction takes place. Most modern surveying equipment use a combination of optics, allowing for dual selectable lasers, huge amounts of memory for recording (including tens of thousands of measurements), lightning fast response times for calculations, and pinpoint accuracy.

What is a surveyor?

In order to use survey equipment you will need to be a qualified land surveyor or construction surveyor. Land surveyors use their skills to mark out land by using recorded documents like deeds, historical evidence and current surveying standards and practices. These surveys are often used for mortgages, condominiums and titles. Construction surveyors are as experienced as land surveyors, only they specialise in the construction industry. This type of surveying is used to establish where man-made objects like pipes, buildings, bridges and highways should be located, and these surveyors also help ensure that projects like roads have been finished in terms of dimensional measurements like length. 

One of the main tasks of construction surveyors is ensuring that a building or other project will be placed on solid, stable ground. Surveyors are also used in the mining industry, and are involved in the construction and development of mines around the country.

How to survey with GPS?

Global Positioning System (GPS) technology has been incorporated in the surveying profession to accurately land mark and survey areas. Due to GPS technology and its ability to give positions of latitude, longitude and height accurately without traditional methods of measuring angles and distances between points, it has become a great tool in making surveying accurate and easy. This equipment can be used almost anywhere with data broadcasts coming directly from satellites. Types of GPS systems used in surveying can include GPS Baseline, Kinematic GPS and Continuously Operating Reference Stations. 

Operations of the GPS can vary however generally GPS surveying equipment works by placing the GPS unit in a static location, clear of obstruction in order to accurately get the correct coordinates. Then by positioning the tripod or antenna receiver the area can be calibrated. Siting the instruments ensures that location from the receiver to the control GPS unit are calculated allowing the surveyor to plot and measure the surveying area and mark points on the survey map. The receiver is then moved to the next plot point. Depending on the number of plot points needed in the survey and the requirements of the project can alter the amount of times the receiver needs to be moved. The survey is then completed when all points have been established and calculated through the GPS locations. If you are in need to GPS surveying equipment or a qualified surveyor iSeekplant has a range of businesses that can assist you in Brisbane, Perth, Sydney, Darwin and Australia-wide. 

What are the different types of surveying equipment?

Base stations are tripod-looking devices with built in GPS capabilities that are used to transmit and receive positioning data to and from other devices and machines on site. They are a hub of sorts for GPS accuracy control on site. Their core purpose is to keep the GPS machine control systems across the site (which are mounted to various machines) in check, ensuring location data remains accurate. Depending on the size and visibility of the project site, you may only need to use a single base station. This device is important as it helps to ensure accuracy on site.

GPS machine controlled systems, like the Topcon 3D-MC² and the Topcon Millimetre GPS+, are devices mounted on machinery which communicate and transmit location data. They provide high-accuracy position control for machines across work sites, where these devices typically deliver continuous high accuracy elevation information to improve positioning. These devices communicate with a base station for quality control purposes, whereby the base station applies accuracy corrections to the GPS machine control system.

Laser levels, like the aLine AL-HVR and Topcon RL-H4C, are control tools that utilise a laser beam projector, typically mounted onto a tripod. In layman terms, a laser level is a device that assists in accurate leveling on sites. For example, it assists in tasks like levelling sand fill in trenches. 

Pipe lasers, like the Topcon TP-L5 Series and Topcon RL-200, are designed for use within pipes. While these devices vary slightly depending on the make and model, they typically offer a reliable and repeatable grade measurement, wide grade range, with quality slope range and operating times of over 90 hours.

A total station, sometimes known as a total station theodolite, is an electronic/optical survey instrument used for measuring distances and angles on site. A total station, a transit theodolite, features EDM integration allowing operators to easily measure angles, slope distance, collect and process data through the use of an on-board central processing unit, and perform triangulation calculations. 

UAV and drones are innovative machines commonly used for mapping, surveying and aerial inspections. In the construction world, you’ll typically find them being used to survey large parcels of land or sites that may be difficult to survey by other means. Survey drones are typically equipped with a range of radar and data processing technologies, like LiDAR sensor sets (like inertial measurement units/IMU, scanners and GNSS/Nav), allowing them to scan, record and relay high quality survey data wirelessly, and sometimes faster than alternative means, depending on the project. 

What are the hire rates for survey equipment?

For a pipe laser or laser level hire rates can vary between $70/day to $320 weekly. For GPS equipment hire rates increase significantly with rates ranging from $330-500/day and up and over $1000 for weekly rental. For total stations rental can be $110/day and increase to $440 for weekly rental. These prices can vary depending on the business and the type of equipment specifications needed.

As rates vary considerably depending on supplier location, equipment type and size, be sure to get a few rates through iSeekplant to ensure you get the best rate for your project whether it is in Brisbane, Sydney, Melbourne, Adelaide, Perth, or Australia-wide
