Under the NHS Frameworks Scotland scheme, the firm has been earmarked as principal supply chain partner to deliver the new North Ayrshire healthcare facility in Irvine.
Design work on the scheme has just started and construction work on the project is expected to begin next year.
Dawn is part of the RD Health consortium, which includes Stirling-based Robertson Construction.
The project includes a new community hospital and a new mental health facility.
The community hospital is likely to include an outpatients'department, care of elderly people facility and a rehabilitation centre.
Discussions are also underway with client NHS Ayrshire & Arran and with North Ayrshire Council about the possibility of including a leisure centre as part of the development.

Alan Caldwell, RD Health's framework manager, said: "Partnerships developed by the NHS Framework scheme can offer key benefits when delivering capital projects.
"These benefits can include both earlier and faster delivery times, value for money and established expertise in the design, construction and maintenance of NHS developments throughout the Scottish healthcare system."
