To facilitate the project management and
implementation, Liantang/Heung Yuen Wai Boundary Control Point and Associated Works of the
Project is divided to six CEDD
contracts including Contract 2 (CV/2012/08), Contract 3 (CV/2012/09), Contract 4 (NE/2014/02), Contract 5 (CV/2013/03), Contract
6 (CV/2013/08) and Contract 7 (NE/2014/03) and an ArshSD

completion for the Works for Contract 2, 3, 4, 6, 7 and SS C505 has been
achieved in 2019. Proposal for
partial termination of the construction phase EM&A programme
for Contracts 2, 4, 7 and SS C505 was approved by EPD on 9 July 2020 (EPD’s
ref.: ( ) in Ax (3) to EP 2/N7/A/52 Pt.17). Moreover, termination proposal for
Contract 3 was approved by EPD on 4 May 2021 (EPD’s ref.: () in Ax (3) to EP
2/N7/A52 Pt.18). Therefore, air quality monitoring stations AM1c, AM8 &
AM9b, noise monitoring stations NM1, NM7, NM8, NM9 & NM10 and water quality
monitoring stations WM4, WM4-CA & WM4-CB and ET’s site inspection and audit
