Glasgow Prestwick Airport - Concrete Infrastructure Maintenance

CLIENT

Glasgow Prestwick Airport was purchased by the Scottish Government in November 2013 to protect jobs and safeguard a strategic infrastructure asset. The airport operates as a commercial business at an arm’s length from the Government. 

There are approximately 290 staff working across areas including business support, passenger handling, cargo, air traffic control, compliance, fire services and a number of other areas, all running of the airport with the view of returning the airport to a position of profit and long-term sustainability.

CHALLENGE

Glasgow Prestwick Airport engaged with LAML to undertake a review of their existing asphalt and concrete infrastructure including undertaking a detailed runway survey. LAML proposed a 5-year maintenance plan for the client to enable them to prolong the life expectancy of their current infrastructure without having to commit major capital expenditure at that current point in time.

• In November 2020 LAML carried out a visual inspection survey to advise the airport on pavement condition

• LAML proposed a schedule for potential maintenance works in line with budgetary constraints

• The survey established that the existing concrete pavement was in a structurally sound condition however the existing joints would require remedial work to prevent any water ingress

• Without the joint sealant being replaced water ingress would lead to eventual failure of the existing concrete bays

BENEFITS

• In January 2021 LAML undertook maintenance repairs on Taxiway Romeo

  • 9000lm of saw cutting and sealing works were carried utilising hot applied joint sealant N2

  • 335m2 of localised Maxi-Crete concrete repairs were carried out on the taxiway

  • Works took 3-4 weeks to complete with no delays or issues

  The works undertaken by LAML have extended the life of the pavement. With less unplanned reactive maintenance required there have been cost savings to the airport, increased asset availability as well as a reduced environmental impact by utilising these life-extending maintenance techniques.

  Since 2021 LAML has undertaken a variety of additional maintenance projects such as general surface maintenance and improvement works to a number of Taxiways and Stands, which have incorporated the following:

  • Maxi-Flex and Maxi-Crete repairs

  • Concrete bay replacements

  • Asphalt patching and surfacing

  • Asphalt Preservation treatment to Charlie & Foxtrot Aprons

  • Overbanding

  • Saw Cutting & Joint Sealing

  • AGL civils works
