The National Scientific Technical Union in Bulgaria (NTSSB) is the oldest creative-professional organization which brings together civil engineers, engaged in secondary and higher education, public administration, construction and design organizations, as well as in training and supervision of MS and PhD students.
The Union performs various public activities in favour of its members, supporting their professional development and creative progress. NTSSB organizes courses, seminars, national and international scientific and scientific-practical conferences. This action is carried out in close cooperation with a number of public bodies - higher and secondary schools, chambers of constructors, investment design engineers and architects, relevant commissions at Bulgarian ministries and at the Bulgarian Parliament.
Scientific Conference on „Civil Engineering Design and Construction“ is held every two years, it began in 2000 as a national Conference of the Union of Bulgarian Construction Engineers and the Bulgarian Scientific and Technical Union of Civil Engineering. Currently, this is already the tenth Conference and for the seventh time with international participations.
