Webinar: Demystifying Temporary Working Platforms for Piling Rigs and Cranes About the Webinar The design and construction of temporary working platforms and their access tracks is required to safely operate piling rigs and cranes. However, temporary working platforms can add significant costs to construction projects and it is therefore important to optimize their design and construction methods. Specialist piling or ground improvement contractors can win or lose projects based on their working platform requirements and the associated cost, program and safety implications can vary tremendously, depending on various parameters which are briefly discussed in this webinar. The design and construction of safe and efficient temporary working platforms requires a detailed understanding of the pile construction methodology or the most critical crane lift as the plant loads applied through tracks or outriggers can vary with different activities like standing, tracking, lifting, drilling of extracting of piling augers. The assessment of such pressures is complex and typically requires experienced personnel with in-depth knowledge of the different operational modes of different piling and/ or lifting operations. Such load inputs are critical for the working platform design. However, the subsurface conditions are as important as the load inputs and they must be sufficiently understood by the temporary working platform designer in order to correctly select the geotechnical design parameters. The platform design can be carried out by following different approaches and the presentation will briefly introduce two common design methods (BRE470 and TWF2019). After the successful construction of the platform, suitable verification methods are applied to provide evidence that the platform was built to meet the required design criteria and after the successful verification a platform certificate can be issued to the piling contractor/ crane supplier to confirm safe operations under the given load/ sub-grade assumptions.

TWf webinar The City of Gold Coast required an upgrade of the existing recycled water release system at the Southport Seaway, to accommodate continuing population growth. The project solution included a pipe capable of transferring 6,300 l/s of recycled water from the mainland across the Broadwater seaway via a marine pipeline to an outfall located off South Stradbroke Island. In order to protect the waterways from environmental impacts, an alternative construction method to the original dredged pipeline plan was proposed by the builder John Holland and their specialist subcontractor Bothar Boring and Tunnelling Australia (Bothar). This alternative adopted trenchless construction using micro tunnelling (MTBM) methods. The project involved the tunnelling of two separate drives, the first being a 1385 m length of bored tunnel beneath the Broadwater Seaway between Quota Park on the mainland and South Stradbroke Island. It included the construction of two deep shafts and a 2.5 m (OD) reinforced concrete carrier pipe that was installed with pipe jacking techniques. The second drive involved a trenchless 617m crossing between Quota Park and O’Connell Park, including a section beneath Biggera Creek that was constructed using pipe jacking and micro tunnelling using a 1.940 m (OD) glass-reinforced plastic (GRP) pipe. Golder was engaged by Bothar to join the project team and provide temporary works design support, design services for the tunneling works, construction support that included site attendance across both drives. This presentation will discuss some of the challenges from the designer’s perspective. Speaker Trevor O’Shannessy, Golder, Principal Geotechnical Engineer Trevor has over 20 years of experience in civil, mining and water industries. He has extensive experience in geotechnical investigation, design and contractor supervision. He has led complex geotechnical and geophysical investigations for many tunnelling projects, including the initial Hobsons Bay Crossing Study, the Melbourne Main Sewer Replacement Project and for development of the Westgate Tunnel Concept Design.

One Za’abeel sits at the absolute centre of Dubai, in a strategic position as a gateway to the new business districts of Dubai. It is comprised of two commercial towers linked by a 226m horizontal steel structure 100m above a busy, six-lane highway. The horizontal structure, known as 'The Link' is fixed to the two towers and cantilevers 66m. The Link will house restaurants and shops and have an infinity pool on its roof. Key takeaways For complex structures construction load cases can far exceed the permanent works design capacities. The sequencing and analysis during the erection is a fundamental engineering requirement to safely build complex structures and ensure no part of the structure becomes overloaded or unstable. Movements during the construction staging need to be predicted and the building constructed with presets to achieve final as-built geometries.

Demystifying Continuous Flight Auger (CFA) Piling An Engineering Education Australia Webinar Continuous flight Auger (CFA) piling was introduced in Australia in the 1970’s. The technology has been used as niche product until about 2005 and with the growth of the cities on the East Coast, CFA piling became more attractive, mainly due to high production rates compared with conventional reinforced concrete bored piles. CFA piling can be an efficient and cost-effective method for foundation piles to transfer building loads into the suitable bearing layers. The method can also be used for embedded retaining walls like secant piled walls or contiguous piled walls, providing enhanced stiffness and water proofing performance than king post or sheet piling walls. However, the installation process of CFA piles includes some risks which could cause significant performance issues with respect to the load-settlement behaviour of foundation piles, alignment and water proofing performance of retaining walls, the integrity of pile shafts and excessive ground movements in the proximity of the pile location. The latter has caused significant defects on existing structures due to uncontrolled settlements caused by insufficiently executed CFA piling operations. Hence, potential installation related impacts of CFA piling on the permanent design performance and on the behaviour of adjacent structures (e.g. buildings, services, working platforms, etc.) needs to be considered when selecting CFA piles. The webinar will introduce some of the key installation risks of CFA piling and how those risks can be assessed and mitigated. Such risk assessment and mitigation strategies depend on ground conditions, size of the selected piling equipment, adjacent buildings/ infrastructure and the overall scope of the piling works. The webinar also discusses some special requirements with respect to concrete placement, performance, technology and testing for CFA piling as a large number of defects in CFA piles are related to inadequate concrete performance. Learning outcomes Understand the benefits of CFA piling technology Understand the key risks associated with CFA piling Gain applicable strategies for the mitigation of risk when using the technology Learn some of the special requirements associated with CFA piling such as concrete placement, performance, technology and testing Is this course for you? This webinar is suitable for professionals in the building and construction industry involved in ensuring or assessing the structural integrity of new builds. Topics we'll cover Introduction of the general methodology of Continuous Flight Auger (CFA) piling and typical areas of it's application for foundation piles, retention systems and ground improvement schemes Introduction of the key advantages and major risks of CFA piling, especially in granular soil conditions below the ground water levels Discussion of some robust risk assessment and potential mitigation strategies for CFA piles during the drilling and the concrete placement process Discussion of general concrete technology and suitable testing requirements for CFA piling Facilitator Dr Martin Larisch is a Principal Geotechnical Engineer and Technical Leader for Jacobs in ANZ.

Webinar - Erection of the ANI building The main assembly building at the Australian Naval Infrastructure (ANI) is 200 metres long, 90 metres wide and 50 metres high. This presented significant challenges for the erection of the shed that are magnified by its size. Robert Bird Group (RBG) and Lend Lease (LLL) developed an erection methodology. This reduced the need to work from heights and maintained the sheds stability throughout the erection procedure. The walls were preassembled at ground level and rotated in place and then the roof was assembled at ground level and then jacked into place. Join us to learn more.

Constructability Considerations for Structures on Major Infrastructure Projects Has the gap between design engineers and construction engineers widened over the past 30 years in Australia? Design engineers work mostly in the office environment and do not get enough site-based experience to inform their design to make it constructible and practical to build. Conversely, construction engineers do not get the experience of working in a design environment and in a lot of cases, lose their design skills. Can we do better? Our two presenters are deeply experienced in the design and construction of major bridge and civil structures both in Australia and overseas. Both Tim and Colin worked on the Phu My bridge in Vietnam in the mid-2000s, a 2km long viaduct with a cable stay span measuring 380 m over the Saigon River. You will hear their perspectives and thoughts on integrating constructability into the design phase of a project and how this carries through to the end.

Geotechnical engineering; science or witchcraft? Speaker: Rahsn Witt The field of geotechnical engineering seems to be filled with people who think that by poking their finger into some soil or hitting a rock with a hammer they can magically obtain all the material properties required for design (often we do). The material properties obtained by the magic finger include unit weight, effective friction angle, effective cohesion, undrained cohesion, and elastic modulus. Even on major projects, material properties are often conjured up on the basis of typical values according to soil consistency. Why don't we do more testing? On the same projects where we magic up the properties for the soil, we test three cylinders of concrete from every truck. Testing soil is difficult and expensive, there are challenges related to field sampling, laboratory preparation and physical constraints of apparatus. In some cases, field testing is appropriate to the conditions. Field tests can be used in isolation; however, when used in conjunction with appropriate laboratory testing there is potential to save significant resources, both time and materials in geotechnical design.
