eMesh concrete steel mesh replacement
100% RECYCLED MACRO SYNTHETIC FIBRE CONCRETE MESH
mesh deliveries, and reduced pre-pour engineering inspection requirements for eMesh reinforced concrete (no steel mesh to inspect).
The process to have eMesh approved for use on the B2M project began in late 2019 and early 2020, where, after consultation, design checks, environmental assessment and inspection of existing SUPs at Skeleton Creek (Hobsons Bay, constructed in 2017), a decision was made by NWPA to present a proposal to Metro Trains Melbourne and the Level Crossing Removal Authority for use of eMesh. The proposal was accepted and eMesh was implemented into the project.
Throughout the approval process, which took more than 6 months, and then implementation, there were clear learnings that to introduce a product that is non-standard, the assessment process needs to be clear and concise, backed by evidence and published research. The practical implementation also requires engagement with all levels down to the subcontractor on site. Clear knowledge sharing around how to use, design with and environmentally assess the new product is a key part of success, and B2M showed us this needs to be a strong focus.
For future projects, the engagement of all parties, from concrete suppliers to contractors placing the concrete, is paramount to continued improvement and achieving quality outcomes. Lessons learned are already being implemented across many LXRP, MRPV and RPV projects and will continue to be shared to create continued improvements and quality outcomes.
