Specific challenges
 Psychological
and emotional challenges
Directive without possible interpretation
or alternative procedures
Open for interpretation and gives
alternatives
Ease of use even for technicians
Requirement for more qualified
personnel
10
Specific challenges

The need for expanding and adjusting the
Latvian technical terminology
Cavity wall
(no term in Latvian)
•
Unbonded tendon
Latvian translation:
Spriegojamā stiegrojuma
elementi bez saistes
• Shell bedded
wall
(no term in Latvian)

Conclusions
Latvia has no other alternative than to participate in the
Eurocode normative base of the European Economic Area
Prolongation of the coexistence period negatively
affected
the education process and construction industry
The
introduction of Eurocodes serves as an impetus for
expanding and developing the Latvian technical
terminology
There
are need for the list of technical literature
recommended by officials or EC developers
Specific challenge is to standardize design
rules in userfriendly way for common structures and must not be
blocked the progress of developing the new ones
