    Aberavon seafront is one of Wales’ longest beaches and has a contemporary promenade overlooking Swansea Bay.

    Developed in a two-stage process, Knights Brown initially completed the ECI phase before being awarded the main contract for the construction works along the 2.1 km seafront.

    This major engineering scheme comprised the following main packages:

    • 1,150m of rock armour to protect the toe of the sea wall
    • Remediation to 1,150m of reinforced concrete steps
    • Construction of a new slipway
    • Access improvements

    We laid over 30,000 tonnes of rock armour along the length of the beach, maximizing the reuse of excavated sand as backfill.

    Located at the western edge of the Bristol Channel, which has a span of 45 km, the project was subject to the second highest tidal range in the world. Careful consideration was given to working safely and maximising productivity in the inter-tidal zone.

    In support of the local economy and to reduce carbon emissions, we sourced the bulk of material from nearby quarries and deployed in-house plant and local resources.

    Work was able to continue through the pandemic. On one ‘clap for key workers’ Thursday, our team expressed their gratitude to frontline workers, writing ‘THANKS NHS’ in the sand.

    our sectors

    Knights Brown was a great client to deal with. We felt from the very outset that they worked with us rather than for us, demonstrating real collaboration in order to minimise disruption to the port. The works were also delivered through a very challenging time, with the latter stages coinciding with the COVID-19 pandemic. Their approach to this was thoroughly professional, with health and safety the primary consideration. Working practices were strictly amended and monitored, with the project completed to the satisfaction of all involved.

    This complex and challenging project was a collaborative undertaking from the outset. Combining two projects was inspirational, saving not only money but diverting 22,000m3 from landfill. Some extremely innovative tools and methods were used to demolish the pier, recover material and to achieve the lowest environmental impact on one of the most environmentally designated places in the UK.
