Specific challenges

Directive without possible interpretation or alternative procedures

Ease of use even for technicians

Open for interpretation and gives alternatives

Requirement for more qualified personnel

Specific challenges The need for expanding and adjusting the

Latvian technical terminology

Simplified design method for piles

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 user- friendly way for common structures and must not be blocked the progress of developing the new ones
