A Griffith University engineering student is working with GHD to investigate the use of drones and laser scanning technology to monitor the integrity of bridges in South East Queensland.
Monique Quirk (pictured above) is studying a Bachelor of Civil Engineering at Griffith University, while completing an industry placement with GHD.
She is in her fourth year of study, and undertaking work placement as part of Griffith's School of Engineering's Industry Affiliates Program. This program allows students to undertake work experience either internally with academic staff or externally with industry professionals.
Quirk has a keen interest in tunnelling and geotechnical engineering as well as construction, and is using the degree to build skills in order to compliment her degree.
"My project with the company is to look into alternative technologies to inspect and model the current condition of bridges and piers around Brisbane, whilst identifying cracks or defects which may affect the integrity of the structure," she explained.
GHD undertakes a variety of services for existing bridges, utilising both visual inspections and desktop-based modelling in order to assess the current conditions of structures and establish an overall condition rating, as well as maintenance recommendations.
Its studies help authorities determine the capacity of the structures under current and future rail traffic. Based on the results of these studies, governments may impose speed restrictions or weight limitations for travel on structures that do not achieve current traffic loads or future proposed loading requirements.
As technology evolves, so too is GHD exploring new ways to inspect and assess structures.
"We use drones and laser technology to scan the structure and then input it into modelling-based programs for assessment," Quirk said.
With the use of 3D modelling programs and technology becoming an industry standard in engineering, Quirk's internship will allow her to gain some skills and insights into that area.
