Work involves the installation of a layered cap onto a prepared, filled landfill or landfill area. The layers which make up the layered cap consist respectively of gravel, sand, geomembrane, geotextile and topsoil, with vegetation planted in the topsoil layer. In addition, gas works, including vertical extraction wells, piping/connections and appurtenances integrated with the layered closure system, are also installed.
The construction/installation of gas works within the Phase 3 SE and Phase 3NE areas are included in the Work. The City’s Consultant has prepared the Specifications and Drawings for the Work which includes, but is not limited to, the following work outlined further within Schedule 2 – Specifications and Drawings:
The Ewen Avenue reconstruction project contains a large scope of work ranging from utility installation to road construction and landscaping. Some the tasks include the following:
- Greater Vancouver 600 mm water main installation
- City of New Westminster 250 mm water main installation
- City of New Westminster storm installation
- City of New Westminster sanitary force main installation
- Shaw and City of New Westminster electrical installation (sub-contracted out)
- Road re-construction
- Road widening
- Multi path installation
This project poses many challenges which include some of the following:
- Coordinating with New Westminster residents
- Maintaining traffic along Ewen Ave. while maintaining production
- Managing water levels in the utility trenches as it is below sea level in some cases
- Excavating and installing utilities near existing utilities under ground
Widening existing 2-lane arterial connector to Hwy 1 to four lanes. Clearing, excavation, replacement of storm, sanitary & water services to existing homes, 1500m2 retaining wall, new catchbasins, granular base & subbase, new curbs & sidewalks, asphalt paving, decorative handrail, relocation of BC Hydro & Telus infrastructure, upgrading signalizing three intersections, streetlighting & property restoration. Main challenge is to maintain continuous two-lane traffic on paved surface and continuous access to private properties whilst building the new roadway and utilities.
-Leachate Pump Station upgrades including application of poly-urea coating in leachate tanks, several road crossings, HDPE air, leachate and gas pipe-lines, supply & installation of gas well de-watering system
Installation of a 1200 mm dia Concrete Storm Sewer, road widening from two lanes to four, addition of a multi-use bike path, traffic signalization and street-lighting.
This project consisted of the supply and installation of a geo-membrane closure system (5.5 Ha area), gas extraction well drilling, excavation, grading, construction of a leachate and gas collection system, gas system upgrades, a 4 Ha double-lined surface water detention pond and erosion and sediment control measure. All work was substantially complete within a short time of 3.5 months.
The 96th Avenue project involves ultimate Arterial Road widening including storm sewers, water mains, curb & gutter, paving, sidewalks, street lighting, traffic signals, retaining walls, preloading and bridge construction in the City of Surrey along 96th Avenue between 160th Street and 168th Street. One of Surrey’s major federal stimulation funded projects, a major portion of the project was completed in March, 2011. A second phase of the bridge crossing Serpentine River was completed in the summer of 2011. The major challenge of the project is the road construction between 160th to 164th. Construction in the area involves excavation and road construction work on existing properties on both sides of the Arterial. Major property restoration and reconfiguration to the properties in the area are part of the work in this challenging project.
The project consisted of widening Nordel Way to implement left-turn lanes at Brooke Road and Shepherd Way intersections along with the installation of drainage improvements and a centre median along Nordel Way. To accomplish this work a retaining wall was required in an area that was considered to be environmentally sensitive as well as all new street lights and intersection signals were installed. At the completion a sound barrier wall was constructed on both side of Nordel Way.
