The first official results of the investigation into the case of Alba Iulia St will be made public by the middle of this week. An order to this effect was made by Mayor of Chisinau Dorin Chirtoaca, who expressed his dissatisfaction with the fact that the inquiries last for so long. Deputy mayor Nistor Grozavu says about a month is needed to complete the investigation, Info-Prim Neo reports. Nistor Grozavu said yet that the first results as regards the material used to repair the street will be announced by Thursday. There are examined samples of asphalt taken at the intersection of the streets Alba Iulia and Paris and the results are different. The deputy mayor also said there was set up a technical group consisting of experts of the City Hall and the Ministry of Transport and of representatives of the company that executed the repair works. It already analyzed the plan of action and is to question the building site chiefs and the officials who signed the documents allowing using the materials in repair works. After the investigation is finished, the company that restored Alba Iulia St could be obliged to repair it again. The first fissures appeared three months after the street was fully repaired.
