As a means of extending the company's portfolio of capabilities without diluting core business management resources, Blackwell has focused strategically on the establishment by acquisition of, or investment in, a number of subsidiary and joint venture companies.

Each company provides specialist expertise and operational capabilities to the core business divisions but also operates independently as a specialist contractor to the industry.
