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.
Storm Culvert work began with the demolition of an existing concrete headwall and box culvert. The inlet structure was replaced by a fibreglass headwall and 1350mm concrete pipe connected to a 3,050mm x 3,050mm box manhole 6m deep. The 1350mm pipe was then extended 100m from the manhole and tied into an existing CMP. Installation of the box manhole proved very difficult due to the extreme wet weather, the underlying wet and soft clay supporting the box manhole and the proximity to the guideway. The Roadwork portion included grading, paving, concrete curb and gutter and street lighting on Aberdeen Avenue. Work on Barnet Highway involved realignment of traffic island to effect the change in traffic pattern entering Aberdeen Avenue.
Haul & dispose off site 25,000m3 of bulk & detailed excavation, backfill behind external perimeter walls and installation of 1,800 lm of IBO anchors and 1,000 m2 of shotcrete shoring.
Offsite work includes installation of storm, sanitary, water, hydro/tel and gas mains on busy West Mall and Agronomy Road around the new Vantage College facilities. Trench excavation up to six meters deep, conflict avoidance with existing utilities, and traffic management present constant challenges for the crew. Onsite work includes installation of storm, sanitary mains as well a 175m3 sistern system consists of 2.4m x 2.4m segments of precast box culvert 5m deep, all done in extremely confined space.
The contract for this project involved utility relocation, as well as excavation and shoring for Phase 2 of Wall Financial's Central Park project. First, Hall Constructors relocated 110 meters of 1350 diameter storm pipe and 110 meters of 750 diameter sanitary pipe which are both owned by Metro Vancouver. Once those utilities were moved off of the property, Hall completed the 43,000 m3 excavation by using a combination of secant piles and conventional shotcrete to shore the dig. This project also included installation of BC Hydro, Telus and storm/sanitary services for both phases of the development.
Scope of the project was to place two individual classes of aggregate to a total depth of 2.17 meters for the total length of the 2000 lm of bored tunnel.
Project consisted of select demolition of BC Place, Jet Grout Piles, Driven Pile Piles, Bulk / Detailed / Mechanical Excavation complete with Shotcrete and Anchor Shoring system. Total volume of material removed was 160,000 m3 of which approximately 45,000 m3 was contaminated. Schedule was a major factor on this project and Hall Constructors was able to deliver the excavation 2 months ahead of schedule.
-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
Project consisted of site preparation works to allow for the installation of 354 - 1 metre diameter Secant Piles to an average depth of 17 metres below existing grade.
This 15,000 m3 excavation and shoring project was completed for Marcon Construction in 2015. Though the site proved difficult, Hall was able to work with the Owner to deliver the excavation on time. Extra measures were taken to ensure that the neighboring creek was protected and that silt from the excavation was diverted away from the waterway. Hall also used it's ocean dumping facility to provide the most economic soil disposal option on this project.
