Recent assessments have raised significant concerns about the structural integrity of Johannesburg’s bridges. According to the Johannesburg Roads Agency (JRA), about 78% of the city’s 902 bridges are in poor or very poor condition, with 20 bridges on the brink of closure. The JRA has indicated that addressing these issues would require an estimated R16 billion to bring the bridges up to acceptable standards.
The deterioration of these structures has been attributed to factors such as ageing infrastructure, increased traffic loads, and damage from recent floods, which have led to the collapse of critical components like stormwater culverts and embankments. Budget constraints have further delayed essential repairs, exacerbating the risk of structural failures.
Fast-track, high-pressure bridge demolition projects, where timeous completion and safety performance is critical, is a specialised area of expertise for Jet Demolition. “Here the increased risk and high-pressure conditions lend themselves to our specific set of expertise,” comments Jet Demolition Contracts and Project Manager Kate Bester.
Bridge-demolition projects are typically on a turnkey, rapid-demolition basis. The company’s innovative, state-of-the-art and technically advanced methods and machinery allow it to tackle the most demanding and complex bridge demolition projects.
These range from all aspects of road safety – from temporary road closure design and implementation, to extensive communication and consultation with the general public, and liaison with all relevant authorities – to engineering suitable demolition methods, planning for unforeseen circumstances, and final road clearing.
Emergency demolition is often required where bridge stability or safety is compromised by an unforeseen event, such as traffic accidents that have impacted on a bridge structure, or vandalism causing structural stability concerns. Emergency bridge projects invariably impact on the travelling public as these are, by nature, unplanned and unforeseen.
“One of the biggest challenges on an emergency bridge project is to mobilise our plant and personnel to the works. If a bridge is suddenly compromised, all traffic in the immediate area is gridlocked, until such time that alternative routes are made available. Under these circumstances, we rely heavily on the assistance of traffic authorities to provide emergency escorts to the site, fast-tracking the establishment of plant and personnel,” explains Bester.
Jet Demolition recently successfully carried out the overnight demolition of the Rockdale Road Bridge in KwaZulu-Natal as part of a larger project to upgrade the N3 highway and the EB Cloete Interchange. The company is preparing for the next overnight project anticipated to be carried out in June.
