Temporary Drop Off Zone and Ramp Works – TDOZ Project

London Luton Airport required the design and build of an enabling works package. This included a new temporary drop off zone to replace the existing one, relocated barrier controls, demolition of an existing high level link bridge, new perimeter road and supporting ramp over bridge.

Structures included new lighting, barrier controls and CCTV networking. These were designed to make way for a new multi storey car park and to allow the existing drop off zone to be closed and the site cleared for the construction of the proposed MPT system. The works were required to be delivered in a fully operation environment - to enable the drop off, deliveries, multi storey car park and bus providers to continue working as usual.

Through detailed design and early client engagement Ryebridge put forward a value engineered design for the solution that not only provided greater efficiency in dealing with passengers but mitigated any interfaces the public, staff and operations had with regards to crossing live traffic.

The ramp over bridge structure facilitated a safe, vehicle free pedestrian route from the initial drop off to the terminal. Included within the design was a revamp of the perimeter network of roadways segregating drop off traffic, HGV’s and delivery vehicles and a dedicated roadway for access to the existing multi storey car park.

The ramp over bridge structure designed required 180No piles with 300mm thick reinforced concrete walls differing in height for a length of approximately 100m. The walls and deck to the ramp were constructed in-situ with specifically design panels through a period of approximately eight weeks working 24hrs a day with the total placement of 650m3 of concrete for the structure.

Here are a few top facts:

  • £3.2m total value, inclusive of £400k of additional works delivered within the original time frame.
  • The project started in January 2018 and we completed, on time and to budget, in June 2018.
  • 26000m2 site clearance, 31000m3 excavation and disposal
  • 16500m2 of new roads and footpaths and 1600m new drainage
  • 950m3 concrete, 2250m3 of structural fill material and 2500m of kerbs
  • 14000 man hours worked.
