Lack of funds has been cited as the reason for the two-year stalling of the multimillion-euro Estonian National Museum project in Tartu.
The project is still awaiting €32m ($44m) in funding from the European Commission, which is expected to make its decision by the end of the month.
The European Commission's JASPERS project assistance committee also noted that €100,000 ($138,410) may be to low to regulate flow of surface water to deal with residual pollution on the new museum site.
The committee asked the museum if it would provide €32m ($44m) toward construction, and the museum body is expected is make its decision by 15 October.
A trio of foreign architects, which won the public competition in 2007, designed the museum that features an elongated concrete edifice inspired by the former Soviet military base at the site.
The Estonian National Museum was formerly housed at the same site in Raadi, in a Baroque palace that was destroyed in 1944, according to ERR News.
