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
