    Darren Fagg, Rail Project Manager, Walkers Construction

    Project Brief

    As part of construction works at Waterloo Station, platforms were realigned to cater for longer trains. Toppesfield provided Walkers Construction with resurfacing services.

    Toppesfield resolved logistical difficulties caused by no direct-level access to the site. All materials were wheelbarrowed from delivery points on the street up via lift shafts to the platforms.

    A weight restriction on the platforms limited the size of machinery that Toppesfield could use. This was no issue, the company was able to choose one of its own smaller rollers from its large fleet of plant.

    Delivery
    • One week: nine shifts, thirteen operatives per shift
    • Included 24 hour working windows
    • 180t AC 6 Dense Surface Course
    • All operatives already Personal Track Safety trained
    Achievements
    • Toppesfield accommodated the client’s request to work 24 hours in order to complete the works quicker than intended.
    • Finished on time within the allocated programme duration of the August Blockade
    • Zero accidents
    • Defect free
    Job Title Edinburgh Airport stand development
    Main Client Edinburgh Airport
    Our Client VolkerFitzpatrick
    Completion August 2017
    Contract Type NEC 3 Option B
    Project Brief

    Edinburgh Airport was undergoing expansion plans to create more aircraft hardstanding areas and upgrade the existing taxiways to accommodate evolving aviation technology which meant an ever-increasing number of larger aircraft.
    We provided main contractor VolkerFitzpatrick with surfacing to facilitate the project.

    Delivery
    • The original surface course material specified by the client could not be manufactured with locally-sourced aggregates. Using our expertise and experience of airports, we resolved this, suggesting an AC10 BBA surface course product that we had used at Gatwick airport. The same delivery team from the successful project was also put to work to ensure the same results at Edinburgh.
    • There could be no disruption to the active airport – work took place during night shifts; possession working between 23:30 and 05:30 by ten to twelve operatives per shift.
    • We put our operatives through specific training to gain a permanent security clearance and airside driver training, which meant they did not require escorting on site, improving efficiency.
    • Typical tonnage per shift: 120t Binder course, 100t Surface course
    • Off-site batching plant
    Achievements
    • No disruption
    • All of Toppesfield’s own plant and equipment
    • Accident-free
    • Four week mobilisation period
