Ua hoʻokuʻu wale ʻo Construction Industry Research and Information Association (CIRIA) a me International Association of Dredging Companies (IADC) i ka makahiki indexation update (2023) no A alakaʻi i nā kumu kūʻai no nā mea hana dredging 2009.
ʻO ka paʻi ʻana He alakaʻi i nā kumukūʻai kumukūʻai no nā mea hana dredging 2009 hāʻawi i kahi ala maʻamau e hoʻokumu ai i ke kapikala a me nā kumukūʻai pili o nā ʻano mea kanu dredging a me nā mea hana maʻamau i hoʻohana ʻia i loko o ka ʻoihana.
