The biggest deal is part of The Works regeneration scheme to transform the former Corus steelworks site in Ebbw Vale where the contractor has been in talks since last September.
Willmott Dixon has now been confirmed winner of the £27m contract to build Ebbw Fawr 11- 16 Learning Community School which is due for completion in Autumn 2013.
The firm has also been appointed by Cardiff County Council to construct the new St Teilo’s Church in Wales High School in a £20m deal. The 1,440-pupil high school will also complete in Autumn 2013.
And under the SEWSCAP (South East Wales Schools Capital Working Group) framework, Willmott Dixon has won a contract to build a new primary school for Rhondda Cynon Taf Council.
SEWSCAP is a partnership between 10 local authorities to create a framework of preferred contractors to efficiently procure education projects over four years.
The contract for the new 420-pupil Abercynon Primary School in the Cynon Valley is worth £7.1m.
Neal Stephens, managing director of Willmott Dixon in Wales, said: “These three contract wins are a significant success for our Welsh business.
“We are in a great position for the next year as we look to further grow the business; combining our unique combination of expertise, local knowledge and commitment to quality you expect from a company that’s been around for 160 years.
“Our business is enhanced by a community focus we implement as standard on every project. This includes a pledge to employ locally and use local suppliers and local subcontractors; ensuring that we are recycling the local pound to boost the regional economy.
“We also commit to offering apprenticeships to provide an opportunity for young people to learn new skills as well as our sustainable commitments which include an ambitious aim to send zero waste to landfill and reduce the environmental impact of a project as much as possible through a dedicated 10-Point Sustainability Action Plan.”
