HS2’s first giant tunnelling machine broke through this week at the end of her 10-mile (16km) journey under the Chilterns, excavating the longest tunnel on the HS2.

Two new sinkholes have opened up in a field above the route of the HS2 Chiltern Tunnel in Buckinghamshire.

HS2 has paused works at Colne Valley Viaduct to allow for “urgent remedial works” to be carried out inside the viaduct.

HS2 has completed works on the first enormous V-shaped piers that will carry the Colne Valley Viaduct over a series of lakes just outside London.

A joint venture between Sir Robert McAlpine and subsidaries of Bouygues and VolkerWessels is using an Amazon Locker-inspired delivery system at its HS2 site in Hertforshire.

HS2 has launched a giant, 700t bridge-building machine to help construct the high-speed line’s first and longest viaduct.

Two 2,000t tunnelling machines digging the HS2 tunnel under the Chilterns have completed the first stage of works.

BIM is now the norm for those working in major architectural practices, five years after its mandate, according to the latest Digital Construction Report from NBS.

Align JV, the team made up on Bouygues, Sir Robert McAlpine and VolkerFitzpatrick, has cast the first of 56 concrete piers supporting the Colne Valley Viaduct, set to become the UK’s longest railway bridge, for HS2.

A partnership of the Alan Turing Institute and Accenture is seeking bids from digital twin projects for research funding.
