Upgrading of Existing Infrastructure. Under Agreement No. 59-020, roads were paved in the first communities seven years ago. Since, adjustments have been made in some villages to correct specific problems but, generally speaking, road components (paving and drainage) are working properly. The only major problem encountered involves the drainage system in the lower sector of Salluit. Constructed in 2003, the system was based on a traditional design with ditches and culverts. The sector is however relatively flat which meant that, to create a standard ditch gradient and install culverts at a standard depth (carrying capacity), some ditches were dug to a depth of more than 1.5 m. This situation has made it difficult for drinking water delivery and wastewater collection trucks to access certain dwellings, and increased maintenance work that the municipality is not able to fully manage. (Sand and debris accumulate much more easily in deep ditches and more culverts are needed to give access to residences.) The only other village with a traditionally designed system (2002) is Ivujivik. However, given that the road network in this community is small (2.7 km) and that the topography is steep, the system works well. In 2004, following the road paving project in Salluit, the KRG revised its drainage-system design, opting to make more extensive use of gutters. Gutters have made it possible to significantly limit the number of ditches and replace them with shallow trenches. Trenches are easier to maintain and, without culverts, access to dwellings is improved. Gutters moreover thaw more quickly in spring, unlike culverts. The KRG therefore proposes in this document that the drainage system in the lower sector of Salluit be completely redone. The work would involve replacing several culverts with gutters and require the resurfacing of a number of the roads paved in 2003 in this sector. The problems described regarding the current drainage system have moreover resulted in overflowing and the erosion of certain sections of road (shoulders and pavement edges). Corrective work is therefore necessary to fix these problems too. Overall, it is estimated that 3.1 km of roads (50% of the sector) need to be repaved. It should also be noted that this work does not include paving of the airport access road: it is estimated that 2.5 km of the access road need to be repaved to correct the damage caused by structural deterioration. Once the necessary equipment is in the community, it would certainly prove cost-effective t...
