Value of Contract
£680k
Role Undertaken by Palmers
Provide Scaffolding to allow the provision of additional shops and restaurants on a newly formed Mezzanine floor (level 30) Scaffold Dimensions 18m long 13m wide 17.5m high
Palmers also supplied scaffolding for the M&E fit out in plantroom
Critical Success Factors
Through early engagement Palmers developed solutions with Balfour Beatty and GAL to enable access for decking the floor. Once the steels were bolted up and in situ, a laydown scaffold was erected to the underside of steels to enable the decking of floor to be complete
All the works carried out in the live IDL terminal was on a nighttime basis so to minimise any disruption to the retail shops operations, passengers and other airport workers.
Innovation
The access structure incorporated lifting solutions work which is something Palmers regularly supply as 9m long steel beams were lifted using 3 trolley electric winches landed on scaffold and then trolleyed into the IDL
Inside the IDL support 2 rows of support scaffolds were built and steel spine beams sat on these towers so that beams could span across IDL 27m from the old-world duty free to Joe Malone’s.
Relevant Experience to Gatwick
The contract was carried out within an airside environment at Gatwick and with all works being conducted at night under a strict permit system, on a live airport with tight security restrictions.Before each shift the Night time Activity Briefing (NAB’s) was critical for the works to be carried out as most works were at height but still requiring parts of the terminal IDL to be keep open for 3rd party ’s access such as retail access to shops to restock, passengers flow and other airport workers.
Process
Scaffold Requests – weekly planning meetings which was attended by the project management team
Daily / Nightly Activity briefings before all activities commence
Any changes required to scope were addressed with an EWN which were issued by either party
Before each shift the Nighttime activity briefing (NAB’s) was critical for the works to be carried out as most works were at height but still requiring parts of the terminal IDL to be keep open
