STATION MODERNISATION
On the water’s edge
Matthew Murr, senior project manager at Carillion for the Leeds Station Southern Entrance (LSSE), updates RTM on the works so far in 2014 and what’s next for the project.
C
onstruction is now underway to create the new ‘eye-catching’ Leeds Station
Southern Entrance (LSSE), which comprises a concourse deck over the River Aire and an enclosed building.
The £17.4m project, jointly promoted by Metro and Network Rail, secured £12.4m from the DfT as well as funding from West Yorkshire’s Local Transport Plan, Network Rail and Leeds City Council.
Once complete, approximately 20% of passengers travelling into Leeds from across West Yorkshire and beyond will use the new southern entrance, relieving pressure on the existing entrance and cutting journey times to the south of the city centre.
Carillion won the contract to design and construct LSSE, which will also include open link span bridges to provide direct stepped access from the concourse to the east and west banks of the river. Carillion has worked with Mott MacDonald to develop the detailed design following Aecom’s preparation of the Form A.
Lifts, escalators and stairs will take passengers arriving at the new entrance from areas south of the city such as Holbeck Urban Village to a widened footbridge, which will have customer information screens, ticket machines, CCTV, and cycle storage facilities, leading to a new ticket gateline above platforms 16 and 17.
Construction With a completion date of May 2015, the

construction team has a lot of work to do in a short space of time. But Matthew Murr, senior project manager at Carillion, is very confident this is achievable.
So far the construction company has got its pontoons in the water and a jack-up barge in place for the piling activity; a tower crane has also been erected; and as RTM goes to press piling work has just commenced.
Murr told RTM: “The piling work will take about six or seven weeks to complete. And, so far, it has gone well. We’ve had a lot of negotiations with the Environment Agency and the Canal & River Trust – working with them to make sure they are happy with our methodology before we started to get all the approvals.
“Given the time and effort that both Carillion and Network Rail, along with Mott MacDonald and Aedas, have put into the design thus far, once we are out of the water then things should continue to run smoothly.
“We’ve had plenty of time to establish the limits of the tower crane. We’ve designed the components such that they’re within the working capacity of the tower crane and we’ve also incorporated a lot of the design into the permanent work to assist in the temporary state. So, the working platform which we’ll get on top of the pile caps is designed to accommodate scaffolding – both for the temporary works and for future maintenance.”
During the preliminary development for the LSSE scheme, consideration was given to flood
risk, and appropriate flood risk management measures were discussed with the Environment Agency. A revised flood risk assessment for the project, published in 2012 and updated last year in the light of minor design amendments, said the flood risk is “within acceptable limits”.
As well as starting the early construction work, Carillion is nearing the end of the LSSE design process as it is working up the final details now and has commenced work with its supply chain. For example, the shell and outline connection designs are now finished, and Carillion is appointing contractors to complete the cladding and framework.
“They will come up with some of the intricacies of the connections and we are working with them to do that. So design will run for the next few months, just to finalise those last bits and pieces,” said Murr.
