Heathrow Terminal 2B

The Story

The scaffolding and access challenges have been wide ranging, including safe access provision, loading gantries, protection to new plant and site personnel, mobile gantries, heavy duty support for plant and machinery, weather encapsulation, temporary roofs and vehicle access. All this is in addition to the usual edge protection, marketing banners, signboards and walkways that are common place for a site of this size and importance.  48.3 Scaffold Design are very proud to have been the sole providers of all scaffold design for the last 16 months.

Ian McFarlane, Director for Business & Project Development at XERVON Palmers said: “We are delighted to have been involved with the works at Heathrow’s T2B, which is a superb, top level de-construction and building project. Airport works of this scale always require expertise and knowledge when it comes to providing access solutions”.

The access has been provided using a mix of traditional tube and fitting and modern Cuplok and Layher system scaffolding including the creation of large birdcage scaffolds in the T2B’s atriums and escalator constructions.

Over the months 48.3 have experienced some real challenges. A recent design that really stands out was the heavy-duty vehicle and plant access ramp in the basement of the terminal.

Andrew Kitley, 48.3 Design Engineer who has been heavily involved with the whole project explains, “The problem on site surrounded the slab levels in the North and South basements. Due to the significant difference in level there was no vehicle access route between the two areas. This was causing a huge logistical problem, as cranes were required to move equipment from one side to another.

We designed a ramp and track-way that would support a 12,000kg (12t) forklift truck plus provide access for a pedestrian walkway. The ramp was designed from traditional tube and fitting with 450 aluminium beams, double ledgers and close transom centres. Triple boards were used for load distribution with non-slip ply overlay. The ramp had to turn at one end and angle through existing concrete columns whilst maintaining clear turning space for the plant using it, this created added complexity both in design, and for the scaffolders erecting it.

The entire design scheme was delivered from initial site visit to working drawings, calculations and design risk assessment in under one week!”
