Ensuring Business Continues to Flow

By | News | No Comments

Located between Brisbane and Ipswich, Goodman Commercial Property Group’s Redbank Motorway Estate is an industrial development experiencing significant growth due to the region’s connectivity and the need for fast and efficient logistics, transport and warehousing solutions for major brands.

Boasting tenents such as Australia Post, TNT, DB Schenker, Zenexus, Northline and Tyres4U, it is vital that such a site remains operational 24 hours a day, 365 days a year. Working with APNL Project Managers, the team at Madsen Giersing has been responsible for the detailed design and certification of the site’s stormwater drop shafts and stormwater headwall outlets.

CEO Lasse Madsen gave an overview of the project, “As anyone who has spent any time in South East Queensland will tell you that ‘when it rains, it really rains.’ For industrial sites, significant rain events can pose major challenges. By their nature, they contain large buildings, significant concrete footprints and multiple access roads. Therefore we are faced with a dual challenge during a rain event; a large volume of surface runoff and a pressing need to ensure access at all times. In SEQ, where flash flooding is a common occurrence, the solution is to ensure stormwater is managed effectively, channelling it away from the surface and moving it to the river and creek networks.”

“Our solution for this project was to design a system of drop shafts and outlets that can take the water from the site and efficiently and effectively move it to the Brisbane River. Designed to withstand significant flows, our solution means that even in the worst storm event or prolonged period of rain, the tenants who rely on Redbank Motorway Estate should not be inconvenienced,” said Lasse.

Workbox Design Improves Project Constructability

A key aspect of every project we undertake is ensuring that what we design can be constructed efficiently and safely; in other words, ensuring the constructability of the project by identifying and overcoming any potential obstacles that prevent the solution from being completed.

On a recent project in Western Australia, Madsen Giersing was engaged by Maritime Constructions to support the refurbishment of piled navigation aids for the Dampier Navigational Aids Upgrade project for Rio Tinto. As with many offshore projects, it was essential to provide a solution that would allow team members to access free-standing piles, work above the open water safely and as freely as possible. Our team created a bespoke workbox that allowed them to do just that. The design of the workbox has been approved and formally registered by the Department of Mines, Industry Regulation and Safety (DMIRS), as required by Western Australia’s OHS&W Regulations.  Madsen Giersing worked with the client and DMIRS to ensure this bespoke workbox met the local regulations and was fit for the purpose required by Maritime Constructions.

The workbox is able to be lifted in position against a free-standing pile. A clamp is then installed around the pile to support the weight of the workbox, personnel and their equipment and materials. When positioned, the slings are removed, and the personal have safe access to the pile to work as required.

Lasse Madsen outlined the thinking behind the solution, “For this project, we needed to construct a solution that achieved multiple outcomes. Firstly we had to create a reusable solution that could be implemented on any of the project’s piles. It also had to be safe and provide a suitable working environment allowing work crews to complete their tasks efficiently and easily. Although a simple concept, it was not without its own peculiar challenges.  The workbox solution aided the constructability of the project considerably and provided a cost-effective outcome as it can be reused during this phase of works and on any future remediation or maintenance that may be required.”

Wharf Upgrade Increases Facility’s Lifespan

For almost 23 years, Madsen Giersing has been working in partnership with Curtain Bros on their Motukea Project in Papua New Guinea.

In our latest update, we are delighted to share the works undertaken to upgrade Berth 4 to improve the wharf’s performance and increase its lifespan.

CEO Lasse Madsen outlined the works “This project is a great example of how engineering can help increase the lifespan of a facility, remediate a structure and ensure operational efficiency and performance going forward.”

“Our team were tasked with rejuvenating the structure and did this through the use of pre-cast concrete sandwich panels, which we incorporated into the existing wall. This approach provided a simple, cost-effective solution that was installed quickly, ensuring Berth 4 could return to operation as soon as practical,” said Lasse.
