The Pentre Awel project is being delivered by Carmarthenshire County Council and is the largest regeneration scheme in South West Wales.
An employment hub is being delivered by Bouygues UK and Acorn by Synergie.
It has been set up to help people find jobs in the construction industry.
The hub helps people find out about potential jobs at the site and supports them with training and skills.
Lawrence Beach, client development director for Acorn by Synergie, said: “The employment hub gives people out of work the chance to come and see what the site is like and see if there may be any opportunities that might interest them within the various trades present on site.
“Pentre Awel is a huge site and coming here gives people a real taste of what a career in construction might look like.
“It’s open to all, is very informal and relaxed and is the perfect opportunity for people who think they might enjoy working on site to come and see it for themselves.”
Geraldine Evans, 32, from Dafen, Llanelli, is working as a site labourer for Massey Cladding Solutions at Pentre Awel.
She was interested in working in construction so visited the employment hub and found it very welcoming.
She said: “I’m really enjoying the work.
“There is plenty of work to do, which I like because I like to be busy and I enjoy working for Masseys and their site team.
“There is a really good working environment and everyone treats me with respect.”
Bouygues UK is also supporting apprenticeship opportunities in partnership with Coleg Sir Gar and Cyfle Building Skills Shared Apprenticeship Scheme.
Through Cyfle, Bouygues UK and Whiteheads Building Services are supporting 10 electrical and plumbing apprenticeships.
Harrison Griffiths, a Cyfle technical apprentice who is currently on long-term placement with Bouygues UK at Pentre Awel said: “Doing an apprenticeship is an ideal way to get a start in the industry and it has been amazing working on such a prestigious scheme.
“I would encourage anyone thinking about a career in construction to consider an apprenticeship.”
