The majority of Bellemare’s customers are general contractors involved in hydroelectric projects. Bellemare enjoys a strong reputation for its competence and efficiency in high-voltage powerline work – from excavating for pylon footings through raising the wires. For example, the company installed 300 pylons to connect the hydroelectric complex for La Romaine. It built all of the pylons (as a sub-contractor) for the electrical transmission line between Bromontto Granby, including the access road. Currently, for Thirau Ltd., the Bellemare team is installing 56 pylons to connect a private wind farm to the municipality of Pointe-à-la-Croix in the Gaspéregion. This project is expected to be completed in October 2016.
Bellemare is also known for the quality of its work restoring stone embankments. One of its notable contracts was completed on the nearly 50-year-old Laviolette Bridge across the St. Lawrence River. Bellemare repaired the bridge pillars that were damaged by erosion. The company also brought in 4,000 tonnes of material of various grades carried on a barge equipped with a PC360LC-10 excavator to do the work. Two other Komatsu PC200LC-8 excavators were on the shore filling barge containers while divers inspected the stone setting.
Another noteworthy project involved the installation of lampposts on Highways 40and 55 in July 2015. The company used a Komatsu HB215LC-1 hybrid excavator for the foundations, slopes, and work-site access roads as well as to install the lampposts.
Excavation Bellemare is an all-inclusive contractor on houses that contain pyrrhotite, a major issue in the Mauricie region since the beginning of the last decade. The problem originated with the use of inappropriate concrete aggregates, which caused foundations on thousands of residences and public buildings to deteriorate. In such cases, the work involves lifting up the house, demolishing existing foundation walls and then casing and concreting new walls, plates and slab.
Bellemare also specializes in demolition and recently took down an overpass on Highway 40in Berthierville. For this job, the company used its Komatsu HB215LC-1 hybrid excavator to load 3,500 tonnes of up to eight-inch-thick concrete in eight hours. This job also used 14, four-axle trucks. The advantages of using the hybrid excavator included an additional 60 hp compared to the standard model; increased rotating speed; and a 20-percent savings in fuel compared to the PC210. The HB215LC-1 handled similar volumes as a 36-tonne excavator in this application.
In addition to civil engineering work, Bellemare teams are involved in municipal roadwork for the provincial Department of Transportation. For instance, in Montreal and Lacolle, Bellemare replaced the piping system bordering the road and culverts. The company’s Komatsu PC138 excavator offers the perfect size and specs for this type of work. Bellemare also performs renovation, landscaping and drainage of the Hydro-Quebec distribution center as well as some commercial snow removal.
