PROJECTS

Pool Jacking and Strengthening

The Sebel Quay West Auckland, New Zealand

Situation

The client had already completed a full refurbishment of the hotel and pool area, when they realised that the props supporting the pool had failed and needed to be replaced!

Challenge

To replace the props would be a very delicate task as the pool only needed to be lifted 1-2mm. The primary objective was to elevate each side of the pool separately, allowing for the removal of the existing suspension props and to allow for the installation of the new, permanent engineered props.

Solution

The project involved the precise lifting of the pool, located within the Sebel Hotel , using a synchronised jacking system .Meccanico was responsible for the planning, execution, and coordination of the entire operation. The key objectives of the project were as follows:

1. Lift the Pool: Meccanico aimed to lift the pool by 1-2mm to facilitate the removal of existing suspension props and the subsequent installation of new permanent engineered props. This required a high level of precision and synchronisation to ensure the stability and safety of the pool structure.

2. Separate Lifting: To ensure the existing suspension props could be safely removed and replaced, Meccanico decided to lift each side of the pool separately. This approach allowed for a controlled and systematic process, minimising any potential risks or damage to the pool structure.

3. Installation of Engineered Props: Once the pool was lifted, Meccanico’s team installed new permanent engineered props to provide enhanced support and stability. These props were carefully designed and engineered to meet the specific requirements of the pool structure, ensuring long-term durability and safety.

Conclusion:

By successfully achieving the desired lift and installing new engineered props, Meccanico ensured the safety, stability, and longevity of the pool structure. Our specialised equipment enabled the project to be executed efficiently and within the designated timeframe which minimised any potential disruptions to the hotel’s operations.

This Meccanico project demonstrates how our innovative engineering solutions can be employed to overcome complex challenges in the construction industry.

TESTIMONIALS

Working with the world’s best

I have been involved with Rod and Meccanico for three large bridge lifts on two of New Zealands significant infrastructure roading projects in the last few years. I was the structures lead for the design team and was involved in the construction monitoring during the construction phase of the projects.

Jacking each bridge was a complex operation and required well controlled load and displacements in each of the jacks as we simultaneously lifted (up to 13 beams) concrete bridge beams that were rigidly connected together by a concrete deck.

Our company is also involved in the maintenance for many of New Zealand’s existing bridges and I would have no hesitation in using Meccanico when we need to jack an existing bridge to replace the existing bridge bearings in the future.

Martinus engaged Meccanico for the demolition of an existing wall inside Britomart Tunnel in Auckland CBD. Scope of works consisted of jacking to transfer load from the existing wall to a newly constructed wall, continuous monitoring of deflections, and design of all associated temporary works. Meccanico engaged Quoin to develop the temporary works design in collaboration with Martinus, Aurecon and City Rail Link Ltd. and developed the jacking methodology in accordance with the permanent works design requirements. The jacking works were completed successfully as critical path works during a rail shutdown with a very happy client as a result.

Throughout the works, it has been great to work with Meccanico as a trusted partner to deliver a robust solution, work to the program, and produce solutions where required. Impressed with the ability and flexibility of the team to get the job done. It was a pleasure to work with Rod & team!

We engaged Rod and his team to lift and an industrial warehouse roof back in March 2022 in New Lynn.

Rod visited our site and provided a safe methodology and successfully raised the full roof structure to the heights we required meeting our agreed timelines and budget.

I would have no hesitation recommending Rod and his team and will definitely chose to use them again for any future works we have.

Due to unexpected settlement, the bridge had warped and required intervention to remove the warping stresses. We engaged Meccanico for this challenging operation, which involved synchronous operation of each jack and precise control of jack loads to prevent structural damage.

Under the leadership of Rod, his team worked with efficiency and competence, demonstrating excellent collaboration skills when dealing with higher than expected loads. Throughout the project, Rod kept variations to a minimum and provided a reasonable price for his services.

Overall, we were impressed with Meccanico’s expertise and professionalism in handling this complex project, and we would not hesitate to recommend them to others in need of similar services.
