Location
Vancouver, British Columbia, Canada
Project Duration
August 2020 – April 2022
Background
The Broadway Subway Project is a key link in Metro Vancouver’s transportation system. The 5.7-kilometre line will extend the existing Millennium Line SkyTrain from VCC-Clark Station through the most congested section of the Broadway Corridor to a new terminus station at Arbutus Street. Construction began in 2020 and is anticipated to be completed in 2025.
The project includes six new stations and 700 metres of elevated track, extending from VCC-Clark Station to a tunnel portal near Great Northern Way. Five kilometres will be tunneled below the Broadway Corridor from Great Northern Way to Arbutus Street, with an underground connection to the Canada Line at Cambie Street.
The Broadway Subway will cost $2.83 billion and is being funded and delivered by the Government of B.C., with contributions from the Government of Canada and the City of Vancouver.
Services Provided
Hatfield initially supported all environmental components of the bid, led by the Broadway Subway Constructors General Partnership, a joint venture between Acciona and Ghella, two of the world’s foremost tunneling and sustainable infrastructure companies.
Hatfield was responsible for leading all environmental components associated with the bid submission, including identifying all environmental regulatory and permitting requirements in relation to projects design, developing processes and criteria to guide the development and submission of the final environmental design (as defined in the bid Project Agreement), and the creation of over 20 Construction Environmental Management Plans and Component Plans. Hatfield also attended weekly design meetings with the engineering team and reported directly to Acciona’s Director of Quality, Environment and Sustainability.
Following the award of the project to Acciona/Ghella’s joint venture, Hatfield supported the construction phase of the project with various environmental management services including construction environmental monitoring, a hydrogeological and groundwater quality conditions assessment study for various subway stations, and general environmental advisory and strategic support to overcome environmental management challenges, including the estimation of expected groundwater inflows during construction. Hatfield was also responsible for applying for permits and updating plans, as required. Hatfield’s involvement in these critical aspects of the bid and construction phases of the project contributed to the overall success and sustainability of the project.
