A brand new 4 direction interchange was constructed on HWY 99 at 16th Avenue. The project required the relocation of Ferguson and Carlson Creeks. Two pre-cast panel walls were required for north and southbound off ramps, the later requiring a curved wall. Property acquisitions were untimely so a temporary stream channel had to be constructed to bypass an entire portion of the project site for several months. The project was completed 2 months ahead of schedule.
A new offramp was constructed to provide direct access to the Boundary Bay Airport via HWY 99 Southbound. The Ladner Trunk Interchange also required some interim upgrading to facilitate an acceleration lane for HWY 99 Northbound. This required shoring of the north abutment fill slope and preloading of all new construction with about 35,000m3 of preload. This project was completed on schedule.
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.
This excavation and shoring project had the unique challenge of being located next to a BC Hydro substation, which resulted in a extensive network of underground high voltage conduits. Hall Constructions worked closely with Axiom Builders and the geotechnical engineer to locate all underground utilities and come up with a shoring design that allowed the excavation to proceed without damaging any conduits.
Scope includes removal of existing pumps and electrical works, installation of temporary lighting and ventilation system and filling this 800m long tunnel with cellular concrete.
Hall Constructors completed this excavation and shoring project for Metro-Can Construction in 2014. The final 4 storey building was a significant upgrade to the community, adding commercial shops to the main floor, with residential units above. Hall was able to excavate through the bedrock at the bottom of the excavation and used ocean disposal for the clean soil to maintain the project schedule.
Hall Constructor completed this small excavation and shoring project for Cressey Developments. The major challenges on this site were working on a small building footprint with limited access and sloped surroundings. Hall also worked closely with the geotechnical Engineer to ensure that underpinning of the neighboring building and Granville St Bridge footings was done safely and correctly.
Project consisted of the Bulk/Detailed Excavation of approximately 17,000 m3 for the East and West Head House structures. The excavation was supported by a shoring design consisting of pipe piles, fiberglass anchors, IBO Anchors and Secant Piles. Once these excavations were completed, we completed a 8,000 m3 excavation in 48 hours to facilitate the pushing of the Box Tunnel followed by the rebuilding of the roadway in 24 hours.
This project consisted of a roadworks upgrade including utilities and streetlights.
Hall Constructors completed the excavation and shoring for this 118 unit condominium project, which was managed by Marcon Construction. Included in the 17,000 m3 excavation was the safe remediation of contaminated soils which were discovered during the work. As the project is located across the street from City Hall in New Westminster, much care and attention went into implementing safety measures to protect the pedestrians, vehicles and workers in this high traffic area. Hall Constructors returned to complete the road works and street lighting after the building construction was in the finishing stages.
