HEATHROW CAR PARK GETS DECKED OUT

Multi-storey car park (MSCP) 1A/1B at Heathrow Airport, UK was built in the mid-1960s. Water and chloride ingress from road de-icing salts led to extensive spalling and delamination of the concrete decks, soffits, beams and columns of the car park. Taylor Woodrow Construction was appointed to implement a repair and refurbishment programme to extend the design life of the car park by 20 years. All previous repairs and contamination had to be removed back to 'good parent concrete', including below the existing top layer of reinforcement steel. Significant back propping was required. Details are given of the removal of defective concrete and existing patches by hydrodemolition, the disposal of wastewater, and the mechanical removal of defective concrete. A table is given summarising the main operations.
