History and why we are called "bi"

In 1950 Dr. Friedrich Roß founded the Norddeutschen Wirtschaftsverlag ("publishing company of Northern Germany"). He was the first to publish "bauwirtschaftliche informationen", a professional journal focused on information concerning the building industry. It was printed on yellow paper. Customers soon called this journal simply "the bi".  "bi" finally became the name of this fast expanding company and today stands for "business intelligence" or simply "better informed".

When the first "b.i. Magazin" was published as a monthly journal in the Eighties, this yellow paper became a trademark and the abbreviation "b.i." – including dots – the company’s logo. The yellow bi-Logo as we recognize it today was established in the Nineties. With the spreading of internet commerce, the "Norddeutsche Wirtschaftsverlag" was renamed "bi medien" in 2004.

bi-tendering services – leading role in public procurement

For over sixty years the bi-tendering services function
as a competent and innovative partner for the entire
procurement business. Since 1950 construction work-,
services- and supply-processes have been published
via different bi medien journals.

The daily journal bi-Ausschreibungsblatt specializes
in public procurement – with sufficient reliability and
claim to completeness. As far back as 1996 bi-tendering
services had already established the internet as a
medium for public procurement information. With the
bi-online database
, bi-medien established the world

on a daily basis.

bi-tendering services provide public procurement information according to VOB, VOL and VOF standards as well as planned private/commercial construction projects.

As pioneers for eTendering, the bi-tendering services got involved at the very beginning. Today we publish and monitor contract opportunities from more than 22,000 (twenty-two-thousand) awarding authorities in Germany. The proven competence and the long established trust in the bi-eTendering System ensures to all participants have strong confidence in the tendering process.

Efficiency, effectiveness, transparency and accountability – bi-eTendering serve the objective of the tendering process.
