Jointly organised by the CV, GE and LT Divisions, the captioned seminar with topic “High Speed Two (HS2) railway: the project and its ground investigation” was held on 25 March 2015 at the HKIE Headquarters. We were honoured to have invited Ir Jonathan Gammon, Technical Director, Tunnelling and Earth Engineering and Science of CH2M Hill and Head of Ground Investigations of HS2 Ltd, who has more than 40 years of international civil engineering experience, to deliver the seminar.
HS2 is a passenger high speed railway system linking the cities of London, Birmingham, Leeds and Manchester.
Phase 1 of the HS2 line runs between London and Birmingham, covering a distance of approximately 230 km and has a design speed of 360 km per hour. The construction along HS2 Phase 1 line is anticipated to start in 2017 and will be completed by 2025, while the first train will run between London and Birmingham in 2026. Onwards from Birmingham, Phase 2 of the HS2 will be divided into two lines, one to Manchester and another to Leeds.
After describing the key features of Phase 1 of the HS2 project, Ir Gammon focused on the ground investigation (GI) work, which will be the largest GI ever undertaken in the UK, including more than 10,000 items of fieldwork. The duration of the GI framework contracts is a minimum of four years which have been awarded to a total of nine contractors. Ir Gammon also explained the contractual arrangements between HS2 and its suppliers, and the challenges faced by his team to deliver such an extensive programme of works within a short timeframe. He concluded the presentation with a video for the HS2 suppliers emphasising the importance of health and safety.
Ir Gammon also highlighted the range of major infrastructure project opportunities in the UK. This informative seminar was well-attended by the members, and many
of them even stood for 1.5 hours at the back of the room!
