At Dartford Station, provision of a new landmark structure required robust stakeholder and project strategies. These were meticulously co-ordinated to keep passengers flowing during all operational phases, and to cope with the additional passenger demand during the 2012 Olympic Games.
Keeping Passengers Flowing Throughout
The project at Dartford Station was the largest scheme to be completed under Network Rails National Station Improvement Programme. In addition to the new station building, the extensive scope of works included temporary ticket facilities, refurbishment and upgrading of existing footbridge and platform structures, rewiring, relighting and landscaping.
Through understanding our customers needs, we developed a design which increased the useable floor space and produced efficient entrance layouts to improve revenue through additional parking spaces. Our solution provided a temporary ticket office to allow the station’s passengers to be re-routed away from the existing structures, facilitating an efficient demolition process. In addition, an innovative design was developed for the platform canopy foundations contributing further to minimizing customer disruption, cost and programme savings of the Osborne solution.
Works to the temporary ticket office and platform access were accelerated to prevent disruption to the additional passengers experienced through the station during the Olympic period. John Gillespie, Duty Station Manager, thanked the team, especially mentioning the contribution of our Site Manager:
“Without Duncan’s involvement, the move would have not gone ahead. He was instrumental in ensuring everything was ready on time and solving any last minute problems without hesitation. Nothing seemed too much trouble for him.“
With only six months available for design, prefabrication and advance site works, the replacement of seven rail and platform bridges in a 99 hour blockade saw a fully-integrated team of experts working together from the outset develop a fine-tuned solution and project strategy, where everything had to be right first time.
Collaborative Planning ensures Possession Success
The fast-track project consisted of the re-construction of bridges carrying the four tracks and four platforms of Hackney Downs Station over Marcon Place. Leading the design team, we ensured we captured the requirements of all stakeholders, fully integrating our key suppliers including the bridge fabricator, track works, demolition, transportation, cranage, and scaffolding teams in the design development and intricate minute-by-minute logistical programming of the possession. The timescales did not allow for a trial erection and state of the art modelling engineers were employed to create a 3D model of every new component, ensuring any clashes or buildability issues were resolved in advance of the possession. Nick Elliot, Regional Director of Network Rails South East Infrastructure projects was delighted with the performance of the team and stated:
“This job was a complex and difficult challenge to complete in a 99 hour possession. Despite early problems which led to delays to the original plan, it was encouraging to see the way in which Osborne and Network Rail worked together to re-plan the works, agreed additional time to enable the works to be delivered in full, and then opened to the morning traffic with minimal operational disruption. This level of collaboration is a great model for future success.”
Remarkable Teamwork Re-opens Network Ahead of Schedule
Through a seamless integration between designers, suppliers and our customer, working 24 hours a day, the embankment was reconstructed in only 6 weeks to get passengers safely on the move.
An 80 metre long, 15 metre high section of the railway embankment at Botley in Hampshire failed causing the railway track to sink by up to 2 metres. The emergency works included removal of the track and cables, excavation and removal of the failed embankment, installation of 1100 sheet piles and reconstructing the embankment with over 50,000 tonnes of new material. Just to reach the site required sensitive management of stakeholders to allow 2km of access road to be built through farm land to cater for more than 1000 lorry movements. Rail Minister Stephen Hammond visited the team on site to see the scale of the damage.
Commercial director for the South West Trains-Network Rail Alliance, Sam McCarthy, said:
“This is a huge project and we were pleased to be able to provide the Transport Minister with an opportunity to see first-hand some of the extensive work being completed by our engineering teams. We are very proud of the work being done by our teams to restore this vital link for passengers.”
M&E and building services
At London Bridge Station, Osborne recognised the criticality of the programme deadlines to Network Rail. By gathering the best organisations in a committed collaboration, an innovative commercial arrangement was proposed with the risks aligned to meet key milestones. This resulted in the whole project team being locked into the same project drivers.
Integrated Knowledgeable Team Key to Hitting Critical Milestones
Before Network Rail could embark on the main London Bridge Station Programme, the team had to deliver mission critical enabling works, that only when completed would free up the worksites to release the station build. The enabling works were highly complex with numerous critically interrelated milestones; necessitating the relocation of station control teams, train operating staff and train crews, creation of new ticket offices, retail and enhanced passenger facilities.
Due to the location of the project at one of the busiest railway stations in the UK, we recognised that a partnership with Mace would bring numerous benefits from their asset knowledge and local stakeholder relationships from their ongoing construction of the Shard of Glass. T. Clarke joined our integrated team to provide the M&E expertise required for the extensive services diversions and migrations and together we developed the Project Strategy to ensure a seamless transition from construction to user operational phases. High praise was received from our customer after completing major possession works to demolish existing accommodation blocks:
“Please pass on my thanks to all concerned, including your subcontractors, for a first class professional piece of work over the weekend. This has set a high benchmark for all future works.” Andy Gent, Network Rail
