Detailed Narrative Description of Project:
The M3 corridor connects Chișinău, the capital of Moldova, with Giurgiulești in the very south of Moldova. The two contract sections with new and/or existing alignments, as detailed below, will be part of the M3 road;

Contract RSP/W9/02 – Construction of M3 Porumbrei – Cimișlia Road km 0+000-km 19+010 (FIDIC Conditions of Contract for Construction, MDB Harmonized edition, June 2010)

The project is represented by a new construction from km 34+357 of M3 Road to Cimișlia junction with R3 Road, located at km 19+010 north of Cimișlia. This road sector is designed as a Category Ib Road according SNiP 02/05/02-85, 4-lane road (two lanes each direction) of 19+010km in length. The road construction process is divided into phases. The first phase of the project has been considered in this tender procedure and will include the following main works: construction Monthly Progress Report for August 2020 7

of embankment on the entire width of road, drainage system, pavement with asphalt concrete surfacing for 2 lanes of the RHS, and construction to subgrade level of the LHS embankment, protection with topsoil and grassing of slopes on RHS and on the entire width of LHS, construction and rehabilitation of bridges. At km 1+100, at the junction with L 580 Mihailovca – Sagaidac – Valea Perjei Road, there is a grade separated interchange which was previously only partially built and requires rehabilitation. At km 11+548, where the road intersects the L582 GrădiÈ™te- Costangalia Road there is a grade separated interchange. At km 19+010 the road meets the R3 Cimislia – Hincesti road where there is a grade separated intersection and traffic circle. There are 5 other minor local access bridges along the alignment.

Contract RSP/W9/03 – Construction of M3 Comrat bypass km 0+000 – km 18+263 (FIDIC Conditions of Contract for Construction, MDB Harmonized edition, June 2010)

The Comrat bypass will begin at km 77+015 of M3 Road north of Comrat town and will connect at km 96+800 with the M3 road south of Comrat city. The length of bypass is 18.263 km and will consist of a 2-lane road of 3.75 m lane width and shoulders of 2.75 m width on each side. The Comrat bypass will consist of the construction or rehabilitation/reconstruction of 3 sections. The first section will begin at km 77+015 of M3 road with corresponding km 0+000 of the bypass to km 8+940 and involves new construction. At km 0+351 there is a grade separated intersection with the existing R28 road from Cimislia to Comrat. At km 1+943 there is a road over railway bridge and at km 8+490 there is a grade separated intersection where the alignment connects with the existing R23 road. The second section is overlapping with the existing R35 Basarabeasca to Comrat road from km 8+490 to km 13+586 and involves rehabilitation/reconstruction. The last section is overlapping with the existing section of M3 road and intersects with the R29 Ceadir Lunga – Comrat -Cantermir Road at km 14+715 with a grade separated intersection that involves rehabilitation/reconstruction. The road crosses the Lalpug River at km 17+569, where the exiting bridge requires rehabilitation and there is a grade separated intersection and traffic circle at km 17+958 where the alignment meets the existing M3 Road from Comrat city to Giurgiulești.
