Total Station Survey (TSS) and Global Navigation Satellite System (GNSS) and are two traditional surveying methods that are used to determine precise positions on the Earth’s surface. Both methods have their own advantages and disadvantages, and they are often used in conjunction with one another to achieve the most accurate results. GNSS (per its name) […]
Using drones (including Unmanned Aerial Vehicles, Underwater Vehicles and Land Based Vehicles) and laser scanners to capture data and reduce life cycle costs is an innovative approach that is becoming increasingly popular in a variety of industries, including construction, engineering, and asset management. JJ Ryan Consulting (JJR) own, operate and maintain high-tech equipment such as […]
Granular pavement design is a crucial aspect of road construction, particularly in western Queensland where the harsh climatic conditions coupled with “black soils” can take a toll on the road surface (resulting in undulations and/or structural pavement failure). What are black soils? Soft, deep, fertile black and brown soils make up a large part of […]
What is protected airspace? It is important to consider prescribed airspace constraints when undertaking any works within the vicinity of an aerodrome (e.g. up to approx. 15 km). Crane operations in the vicinity of an airport have the potential to create air safety hazards and to seriously limit an airport’s operations. The most basic surface […]
While autonomous sea vehicles might not receive the same glamourous news coverage as road or aviation autonomous vehicles, preparing our infrastructure for maritime vessel automation will have a much more significant impact on global trade, and therefore national and global economies. In 2019, shipping accounted for 80% of global trade, with the total world shipping […]
As the power of computers and artificial intelligence (AI). continues to develop at a break-neck pace, many companies, governments and individuals are harnessing this power to make the world safer, more productive and far more efficient. As a poster-child for technological development, autonomous drone technology will be increasingly adopted in the industrial sector, playing a […]
Thanks to ground-breaking companies such as Tesla, Google and Waymo edging closer to fully autonomous, self-driving cars every day, the eventual adoption of driverless technology is now broadly accepted as inevitable. The benefits of this technology are numerous, including allowing people residing in remote areas easier access to essential services such as medical treatment and […]
Did you know that awnings are part of the buildings to which they are attached? This makes them the responsibility of the owner of the building, even when an awning is located over a public footpath. An example awning structure is shown in Figure 1 for reference. Figure 1 – Typical awnings structure example Awnings […]
Road corridors in urban areas are increasingly constrained. Tidal flow systems (or ‘reversible’ lanes) are a form of lane management systems that allows traffic to travel in alternate directions within a lane (depending on the time of day or traffic conditions). Essentially, traffic flow during peak periods is improved by making an extra lane available […]
Bridges and other structures are key asset elements in the transport network. In Australia, around 800 organisations are responsible for more than 50,000 public road bridges. State Road Authorities (SRA’s) who are responsible for the high-capacity arterial roads manage more than 20,000 bridges, with local councils typically managing the remaining local roads with approximately 30,000 […]
