Gilmore Place is a master-planned community that will transform Burnaby’s western gateway into an incredible urban hub for residents and visitors alike. Featuring one of Canada’s tallest residential towers, the seamlessly integrated Gilmore SkyTrain Station, world-class shopping and entertainment, convenient office space, and luxurious residential towers, Gilmore Place will redefine metropolitan living in one of Burnaby’s most up-and-coming neighborhoods, Brentwood.
Phase I and II of Gilmore Place is a mixed-use, transit-oriented development in Burnaby, BC consisting of six combined office and residential towers. This development replaced the underutilized space surrounding the existing SkyTrain Station. GIP (formerly GFL Infrastructure) was contracted by ONNI Contracting to install 1,229 secant piles and 2,689 strand anchors to support the excavation for Phase I and II of Gilmore Place.
GIP mobilized four large Bauer rotary drill rigs (two BG 39s, BG30, and BG33) for vertical drilling operations. These rigs were utilized to drill and install temporary-cased secant piles at depths up to 37m deep around the perimeter of the site as well as immediately adjacent to Gilmore SkyTrain Station and the SkyTrain Guideway Supporting Caissons. Gilmore is the deepest secant pile wall constructed in Metro Vancouver under stringent QC requirements.
GIP had mobilized two KLEMM 807-7G drill rigs to drill and install strand anchors to advance the excavation. These anchors were redesigned to take advantage of our ability to install high-capacity anchors.
GIP provided value engineering services for this project and re-designed the shoring based on proven anchor capabilities. This value engineering coupled with site-led innovation like the use of an automated grout plant resulted in significant savings in cost and schedule.
The eastern side of the site had presented the most difficulty when installing secant piles due to the interaction between drilling and a gravel layer above bedrock. To overcome these challenging drilling conditions, GIP used a range of tools and techniques such as oscillators and drilling fluids.
To meet the logistically challenging conditions of working underneath the active SkyTrain running through the site, GIP used an ultra-low headroom configuration of a BG39 drill rig.
