MAB

What MAB does

MAB Obras Públicas (legal entity: Matías Arrom Bibiloni S.L.) is a privately held Spanish civil-construction and public-works company founded in 1970 in the Balearic Islands and now operating nationally across seven regions (Balearics, Andalusia, Galicia, Castile and León, La Rioja, Catalonia, and Madrid). Its business spans four service lines — general construction (Construcción), infrastructure concessions, conservation and maintenance, and construction materials — delivered to public administrations (its primary segment, including national agencies such as Aena, ENAIRE, the Ministry for Ecological Transition, Dirección General de Carreteras, and various regional and municipal bodies) and to private clients. Since 2015 the company has built a specialized airport-infrastructure practice and has expanded its delivery footprint via a Madrid regional office and a Seville regional office alongside its Binissalem (Mallorca) headquarters.

The company's technical differentiation rests on vertical integration into the construction materials supply chain: it operates its own quarries, asphalt plants, concrete and cement-soil plants, a soil testing laboratory, a fleet of heavy machinery (including specialized airport equipment), and recycling/sustainability facilities for waste oils and materials. This self-supply model — supplemented by I+D+i certified R&D on new asphalt mixtures (the RULARMAB project), ISO 9001/14001/45001 certifications, and a Balearic Carbon Footprint registration — supports cost control, supply reliability, and tender prequalification across Spanish public-works procurement.

MAB generates revenue through fixed-price construction contracts awarded via public tender and direct private negotiation, supplemented by recurring streams from conservation/maintenance contracts and concession arrangements. Its go-to-market is enterprise field sales targeting government agencies at national, regional, and local levels, with project showcases and recruitment activity amplified through LinkedIn and its corporate website. No external funding, M&A activity, or institutional ownership is evidenced; the firm remains family-controlled under sole administrator Matías Arrom Bibiloni, with a workforce of over 100 employees and a disclosed track record of more than 1,000 executed projects and tens of millions of euros in project value managed.
