Planum

What Planum does

Planum is a Serbian for-profit, publicly listed construction company (Belgrade Stock Exchange ticker PLNM) headquartered in Novi Beograd. According to its firmographic description, the company is engaged in civil engineering construction and hydraulic engineering projects, operating as a general contractor for infrastructure works.

Founded in 1948, Planum has a 75+ year operating history and currently employs between 501 and 1,000 people, placing it in the mid-cap range among Serbian construction firms. Its operational base is Serbia, signalled by the .rs corporate domain and Belgrade listing, though no exported geographic footprint is documented in the available data. The company operates in a sector — large-scale civil and hydraulic engineering — where revenue is typically project-based, contracts are long-duration, and the client base is structurally concentrated among public-sector infrastructure procurers.

The input data does not disclose products, pricing, customers, management, or financial figures: the company's website is blocked by a verification/loading page, and the supplied firmographic, technology, and corporate-structure records are empty. Consequently, business model specifics (tender mix, contract types, project backlog, revenue per employee) cannot be substantiated from the available evidence; the description above is limited to what is directly supported by the input.
