The firm has been awarded a four-year contract to carry out the work at the Ravenscraig development site in north Lanarkshire.
The site will eventually house more than 10,000 people, as well as the BRE Innovation Park, and is the first new town to be created in Scotland in 50 years.
The first phase of work at the former steelworks site has already been carried out. It included preparation for around 800 homes.
Land Engineering (Scotland) is expected to start on site in August and will carry out landscape maintenance for four years.
The Capella Consultancy is project managing the scheme and commercial director Tony Greig told HW it was a "substantial job".
"There is a certain level of natural landscaping that exists around the site that is being kept as green belt land and areas for public outdoor use so there is maintenance for that," he explained. "There has also been planting carried out as part of phase one that has to be maintained."
The second phase of the project involves creating the town centre at the site.
