Sunderland Strategic Transport Corridor (Phase 3)

Northumbrian Water is planning to carry out water and waste-water diversions and modifications of our network in advance of the Sunderland Strategic Transport Corridor Phase 3. The new dual carriageway which is planned to start in the Summer of 2019, will link the new south side road infrastructure of the Northern Spire bridge to A183 St Mary's Boulevard - A1231 St Michael's Way roundabout. Our supply partners, Esh-MWH will be undertaking this works on our behalf.

Update by Mark Robinson

Morning Everyone,

Another busy few weeks here at SSTC, working along both Deptford Terrace and Farringdon Row. Since my last post, we have moved into the next sections of road and progressing with the pipe installation. Farringdon has had a few issues to say the least, encountering a large volume of buried electric cables up to three meters deep! This has resulted in significant loss of production but we are working hard to overcome the issues and catch up.

Deptford Terrace - Now working from the bus depot entrance down to Liebherr, the team has excavated a trench down the bank and the pipe has been installed as far as the former Alex Smiles yard. Great progress made since closing this section of road and we are hopeful it will continue. We have carried out a few investigative trial holes just outside Liebherr to determine the best connection locations to maintain water supply. We are waiting on key components being delivered today which will be welded onto the pipe above ground before being installed. In the next couple of days, we'll be speaking with all concerned to progress the road closure, capturing the Eastern Bus Depot entrance as well as Liebherr, before we plan the excavation further along Deptford Terrace. This may well be 'out of hours' so I'll ensure another post goes out before works commence should this be the case to give you all additional information.

Farringdon Row - A lot of hard work has gone into this next section since moving up the road on Monday 11th March. Unfortunately, no pipe installed. This is due to the large volume of cables we have encountered which I refered to above. The cables range anywhere between 0.9 - 3m deep and many clash with our pipe. Therefore, extensive hand excavation has been required to depth, before installing temporary works to protect the excavation and more importantly, personnel working inside it. We are working closely with Northern Power Grid to indentiy the cables and have them removed. We're conitnuiing with the excavation this week, hopefully lifting up to a shallower depth before moving onto pipework next week.

Plenty photos from the period to show how we've progressed. 

More from me soon,
