Latvian construction sector quality index and measurement methodology development and survey instrument (questionnaire) development and testing Methodology and index results
Project goals Establish a sustainable quality monitoring system for construction sector services in Latvia, Benefits: Objective data about service quality, Index which can be used by all sector stakeholders, An established methodology and survey, which can be used for periodic research.

Conclusions and recommendations Data gathering through BIS (Construction information system); Various survey completion methods, longer field work period; Organisations to be interviewed at least 300; Sector NGO s encouraged to analyze data independantly. How to spur sector organisation activity in the survey in 2019?
