The contract for the Forrestfield–Airport Link, which consists of 8 kilometres (5 mi) of twin bored tunnels and three new stations, was awarded to Salini Impregilo and NRW Pty Ltd in April 2016.
Construction began in November 2016, with works initially focussing on building the tunnel dive structure.
[3] The entrance is east of the platforms and located on a raised ground level which is held back by a 300-metre (980 ft) long retaining wall.
[4] The station's roof was designed to be easily visible from the surrounding precinct and lead passengers to the entrance.
[6] On the station's front façade and the retaining wall viewable from the platform are two artworks by Adam Cruickshank, Pavel Perina, and George Domahidy, titled Scarp.
On the front façade is a white 3D Jesmonite panel consisting of smaller tessellating triangles which also represent the Darling Scarp.
This consists of three laser-etched steel images accompanied by signs telling local Noongar stories.
It was built by the Public Transport Authority (PTA) as part of the Forrestfield–Airport Link project, which involved the construction of 8 kilometres (5 mi) of twin bored tunnels between High Wycombe and Bayswater and two other stations: Airport Central and Redcliffe stations.
[11] Forward works such as vegetation clearing and service relocations began in November 2015 and continued into 2016.
[12][13] The main contract, worth A$1.176 billion, was awarded to a joint venture of Salini Impregilo and NRW Pty Ltd (SI/NRW) in April 2016.
[20] By the end of 2016, construction had started on the diaphragm walls of the dive structure, and the development application for the actual station was submitted.
[33][34][35] The second TBM, named Sandy, was lifted into the dive structure in September 2017[36] and began tunnelling in October 2017.
[39][40] The retaining wall, which involved backfilling to raise the ground level by up to 5 metres (16 ft),[41] was complete by May 2018.
[42] As the site was divided in two by Dundas Road, with the station and dive structure on the west side and the TBM support infrastructure on the east side,[43] 1 kilometre (0.62 mi) of Dundas Road had to be realigned to pass west of the station.
[51] By February 2020, the sheeting for the roof was being installed and construction on the traction power supply substation had begun.
[54] Works on the forecourt, including the bus interchange, were underway by August 2020,[55] and by September 2020, the lifts from the platform to the concourse were installed.
The change reduced the area dedicated to parking by 8 hectares (20 acres) and was made to allow for transit-oriented development at the station.
[62] Construction on the car park began in June 2020,[5][63] and by March 2021, the structure was complete, with fit-out works following that.
[67] In May 2020, the state government launched a survey for residents and business operators of the City of Kalamunda to have their say on the station's name.
[70][71] On 18 December 2018, state Transport Minister Rita Saffioti announced that the opening date of the project had been delayed from 2020 to 2021.
[82] High Wycombe station was designed to allow for a future extension of the railway south.
The catchment area includes High Wycombe, Forrestfield, Maida Vale, Gooseberry Hill, and Kalamunda.
