The Embassy Gardens contract is Astec’s latest success in the area with a team currently working on St James’ nearby Riverlight development.
Astec Pre-Contract Director Colin Black said: “This order represents a record achievement for the company.
“The success of this bid is an absolute testament to the collaborative approach we adopted, resulting in a bid that not only reflected our competitiveness but allowed us to demonstrate fully our technical appreciation of the project.”
