Separately, the second contract allows CNA Group to continue operating and maintaining the airport's integrated building management system from Jan 1 this year till the end of 2017.

These projects, and other recent contracts, would increase the company's order book from $87.5 million as of Sept 30 last year, to about $102.3 million.

CNA Group shares closed flat at 13.8 cents.
