90 degree Tunnel / Shaft lining elbow formwork

Special Formwork fully enjoyed the challenges this project brought from high uplift forces, to lifting an asymmetrical shape manufactured from man manageable formwork panels wrapped in 20 tonnes of reinforcement.

From all parties the project required collaboration and synchronized thinking both from the planning and design stages and onsite construction phase.

Overall shows how teamwork can conquer some awesome construction challenges
