Calibre is engaged in providing engineering services across the full asset life cycle for mining and resources infrastructure projects.
Its acquisition is expected to boost WSP’s capacity to provide services that will facilitate the energy transition and the decarbonisation of the mining industry.
The Company employs 800 people and has offices across Perth, Sydney, Melbourne and Brisbane.
Along with mine rehabilitation and mine closure, the deal is anticipated to offer WSP prospects in the field of water management.
It is also expected to expand WSP’s presence in the Pilbara region and Western Australia.
The combined entity will have more than 6,000 people across Australia, including over 1,000 resource industry experts.
WSP president and CEO Alexandre L’Heureux said: “This transaction will further position WSP to play a leading role in assisting with the green transition of the mining industry in Australia and globally.
“Our combined business will further increase our technical capabilities and provide opportunities to serve as the partner of choice for mining companies with strong ESG commitments.”
Calibre executive general manager Adrian Chapman said: “Joining WSP will create a leading and highly technically capable firm, adding value to major projects beyond mine sites, and enabling us to bring WSP’s key ESG services to a wider client base.”
The acquisition is subject to customary closing conditions and is anticipated to close in the second quarter of 2023.
