WorleyParsons has signed a five-year agreement for unlimited access to Intergraph's engineering and geospatial software.
The Australian-headquartered firm is best known as an engineering, procurement and construction management (EPCM) provider for large resources and industrial projects.
It is a "longtime worldwide user" of Intergraph software, but chose to sign a global alliance agreement to expand the relationship between the companies.
"WorleyParsons will make Intergraph solutions available globally and use them as part of our reference standard for global project execution," director of engineering systems, Jim Purvis, said in a statement.
It is the second expanded software agreement WorleyParsons has signed in this space of a month.
The company expanded its use of Aveva information management software under a deal signed last month.
