Kier has been brought in early to manage the detailed and technical design of the new Faculty of Architecture, Computing and Engineering as well as a new library building.
The firm will begin construction in autumn under a £26m contract due to complete in time for the start of the academic year in 2018.
Jason Taylor, Kier Construction operations director for South Wales said the waterfront development should also see the creation of 25 local jobs and 250 apprenticeships.
As principal contractor on the project, Kier will be responsible for setting up a collaborative working approach with all other contractors, including Stride Treglown which will continue to be involved in the design process.
As a result, Kier will be based in SA1 for the duration of the build.
The move comes after the training body said “many find the organisation too slow and difficult to deal with.”
The latest changes follow a restructuring of middle management last year which saw 26 out of 188 roles cut.
CITB chiefs said the next stage is designed “to reach many more employers through online services, improved phone support, and face to face services via a refocused CITB Advisor role.”
The new Advisor role will create a “one-stop shop” for business information and advice on training.
CITB said: “This will help companies get the right skills for their businesses, based on local knowledge, and save time by carrying out simple processes – like applying for CITB grants – online or by phone.”
The changes impact 112 existing roles and propose a reduction of 46 roles – with 66 new roles proposed.
Consultation on the changes is currently being carried out.
Steve Radley, Director of Policy at CITB, said: “Too often, our engagement with employers has focused on navigating CITB’s processes rather than looking at what they need.
“This new CITB Advisor role, complemented by online chat, extended phone hours and simpler online processes, mean we will be able to support many more employers with advice and funding.
“These reforms are designed to give the industry maximum return on Levy investment, and a much better service from CITB.
“Employers will start to see the difference in 2016 and our aim is to have many more construction firms not only engage with us, but get the funding and support they need.”
The move comes as the CITB faces a fight for its future as the Government plans to shake-up training for large employers across all industries
