Psychological and emotional challenges

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

• Horizontally reinforced

Specific challenges The need for standardization (EC7)

Developed at national level:
Shallow foundation embedment depth
calculation methodology
Shallow foundation settlement calculation
method
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
