Following a directive from the Department for Transport (DfT), segregation and security between departing and arriving passengers needed to be improved and in many airports this has meant that complete new corridors along existing piers to aircraft stands would be needed.
The modules must adhere to BAA’s Design Standards. We had to conform to guidelines with regards to aesthetics and adopting commonality across projects. Performance criteria were set with regards to acoustics, fire rating, U-values, thermal performance and deflection. We were expected to adopt Manufacturing and Glazing tolerances in lieu of normal construction tolerances. The modules had to be of a size that could be transported on the back of a lorry and lifted into place with the minimum of effort.
BAA demanded a Target cost of £16,500 per linear metre for the corridor modules when Traditional methods of construction were costing £25,000 per linear metre. They wanted 85% manufactured off-site with only 15% construction airside. The supporting structures also varied from flat to sloping, with a maximum 4 degrees pitch.
