Australian industrial conglomerate WestStar has three arms: concrete fabricator Precast Australia, construction contractor Simpec and property developer Distinct Developments.
In the 2019 financial year WestStar was awarded contracts valued at A$50 million.
The A$5 million in extensions includes original awards with Simpec's existing clients in the structural, mechanical and piping and electrical and instrumentation fields.
Simpec managing director Mark Dimasi said having delivered a strong pipeline of contract awards over the past year, Simpec continued to consolidate its position and build its credentials on major projects.
Dimasi said Simpec continued to tender for work.
