The east Hull plant, part of a site that will eventually employ more than 1,000 people, is being built by national company VolkerFitzpatrick. It has asked Composite Panel Services to install about 86,100sq ft of wall and ceiling panels in the facility.
Managing director Andy Miller said: "We are delighted to have secured this contract in what is always a very competitive market. Alongside the work we are already scheduled to undertake, 2016 promises to be an extremely busy and exciting time for our business and will undoubtedly lead to a growth in our workforce both onsite and within our administrative departments.
"This is great news for the local economy as well as our own employees."
The project will see up to 20 staff members working at the site.
All of the employees live in East Yorkshire.
Mr Miller's firm is based in Clay Street, east Hull, and was launched in 1997.
Ian Simmons, senior project manager at VolkerFitzpatrick, said: "Alongside the work we have placed with other local firms, we feel we are demonstrating our commitment to the people and city of Hull.
"We have been most impressed with all aspects of the Composite Panel Services business during the tender process and we look forward to working with and alongside them during the course of the project delivery."
About 200 construction jobs are being created as the 431,000sq ft blade factory goes up.
And VolkerFitzpatrick, which is headquartered in Hertfordshire, has committed to providing a quarter of on-site labour from within a 25-mile radius of the project.
It has already awarded a £12m subcontract to Hull company Neville Tucker Heating.
The Sutton Fields firm will carry out electrical and mechanical building services at the site.
When that deal was announced in August, Neville Tucker managing director Mark Snape said: "It's great news for our local employment teams – it's exciting to have a good project local to home.
"It's good we've been recognised as being able to work on this and at the end of the day Hull has got more talent than people give it credit for.
"To be on the ground floor of something like this is fantastic and this project could lead onto bigger and better things for the whole city."
On completion in September, the factory will be used to manufacture essential turbine blades and components for offshore wind farms.
Humber firm Clugston Construction has also won a separate contract with Siemens, to construct a 132,000sq ft service and logistics centre in Alexandra Dock. It is said to be worth about £11m.
Managing director Steve Radcliffe welcomed the deal when it was announced in September.
He said: "We are excited to be playing a part in building this facility that will play such an important role in the growth of the offshore wind industry and establishing the region as the centre of renewable energy in the UK.
"In delivering this scheme we will draw upon our local construction skills and supply chain which will create further economic benefits for the region."
