Here are some projects that demonstrate our ability to manage complex mandates requiring great expertise in engineering as well as environmental and technical knowledge.
1.Excavation work and the installation of a drain for secondary route of the Sainte-Béatrix Municipality
Following the study of a pavement rehabilitation work conducted by our company, we were mandated to monitor (control/quality) the project according to the technical specifications issued during our submission. The ditch was excavated over a 400 m distance at an average depth of 2.15 m (7') to then install a perforated drain (SOFLO MAXR 320 with filter) of 450 mm (18'') diameter in a filter bed of 750 mm x 750 mm, consisting of 50-100 mm (2-4'') crushed stone. Two sections of the road structure were excavated to 1.05 m (42'') or 1.35 m (54''), depending on the section, over a width of 9 m and a total length of 250 m to rebuild the sub-foundation (900 mm or 1200 mm MG-112) and the foundation of the road (150 mm MG-20). Since the excavation depth was decreased, a geogrid ( RX2000 V type UV) and a geotextile (UV Routex type V) were also installed. The contract ended with the supervision of the spraying and paving of other sections.
2. Decontamination of a residential property after an oil spill (heating oil)
Plasterboard walls and the concrete slab were demolished and removed. The upper floor was temporarily supported during the decontamination work.
Contaminated soil was excavated, loaded into sealed containers and transported to an approved treatment site. Contaminated groundwater was pumped and treated on site by an oil separator which allowed to meet the standards of discharges to storm sewers. Contaminated air in the basement was filtered and discharged from the residence. The upper floor was sealed with polyethylene sheeting and ventilated during the works.
3. Decontamination of an industrial property contaminated with xylene
“Our client, operating in real estate, acquired a contaminated industrial property. In order for the bank to accept the funding, we were contracted to conduct the assessment and decontamination.” After the analysis, the results showed that a portion of the land was contaminated with xylene down to groundwater level, or to a depth of 4 m over an area of about 1200 m2. The soil was placed in piles and treated by ventilation. Groundwater was pumped several times and disposed of in an approved treatment center.
4. Camp of Father Lindsay
Musical Camp Father Lindsay offered a contract to RX Sol & associés inc. (RX Sol) to prepare plans and quotes for the upgrading of waste water treatment on the site for twelve buildings. By the same token, RX Sol & associés inc. has also been mandated to present on its behalf an application to the Ministère du Développement Durable, de l’Environnement, de la Lutte contre les Changements Climatiques (MDDELCC) for said work.
To do this, the office had to inspect the sewage treatment system in place, point out improper installations, make a report of characterization phase I and phase II, do preparatory studies for the design as needed, conduct terrain analysis and soil testings, perform the topographic survey, computer assisted drawing, manage service offer calls following tenders and work supervision.
The system required was a pit in each building (already in place), a fat based trap, a pre-filtration system and an advanced secondary treatment system like a 36m3 Ecobox followed by a 360m2 polishing field under low pressure (three sections of 14.3 m by 8.4 m).
5. Decontamination of an industrial property after a fire
Following a fire incident, a paint manufacturer hired us for cleaning and decontamination of the site. The building was razed, all finished and unfinished products had burnt and were intermixed. We proceeded by sorting different wastes and loaded them in sealed containers for disposal at sites approved by
the MDDELCC. Subsequently, a restoration plan was prepared.
Our close collaboration with the representatives of MDDELCC has substantially reduced the cost of works.
6. Lowering of the water table
Following the construction of a residence near a wetland... We had to design a larger drainage than a french drain to help lower the water table around the
residence, while maintaining the existing wetland on the neighboring property. We offered a viable and economical solution under the circumstances and we made sure that the works were done according to the rulebook and the laws and regulations in force in the province of Quebec, with the authorization of the Ministère du Développement Durable, de l’Environnement, de la Lutte contre les Changements Climatiques (MDDELCC).
