CONCEPT DESIGN FOR A TEMPORARY CARGO BUILDING

AS AN AIRFREIGHT TERMINAL
The TCB as designed has a 72.37m X 50.77m footprint totalling 3,673 square metres of freight processing space and an office attachment of 460 square metres. Its design criterions are as follows:

1. A flexible walling system:
Simple fabric clad panels repeated all round forms the main walls. They are fabricated aluminium framed panels that can be lifted by 2 persons and re-installed without losing its shape, form and accuracy. The same frame will be glazed in areas where there are offices or made opaque where needed. They can be filled with louvres for ventilation and pivoted to become doors where necessary.

2. The working zones:
A clear working height of 5 metres has been allowed for in defining the overall height of the building. Large sliding doors, clad in the same material and motorised are positioned in the middle to give good access for dollies. Internally, diffused daylight will illuminate the whole working zone without the need for artificial lighting. The building is naturally ventilated and the zone where this happens is caged with welded wire mesh for security. Industrial railings shall be installed along the perimeter as a visual deterrent to forklift truckers.

3. The roof structure:
The overhead roof floats over the perimeter wall as a steel demountable and re-useable structure. This roof is partly covered by PTFE teflon coated membrane over the middle and solid metal decking over its outer edges. Daylight will fill the inside spaces, the outer solid roof will shade the entrances. A central steel truss cambered to throw off rainwater and simply supported at three points is the mainstay of the structural system. This is in tubework. Trusses at 7.2m centres fan out from this spine to be supported on perimeter beams lifted 5.0 metres clear off the apron floor. There are no major point loads along the perimeter. Conventional column and beam structure is used over the office roof in a single storey frame. The entire structure can be dismantled and reused.

4. The office extension:
The area has been sized based on a total occupancy of 85 persons that will include all members working in shifts. Based on three shifts, we have sized the services requirements as tabled herein. Security checking areas are incorporated in two checkpoints, one for staff and another for visitors. Rooms for government agencies are provided with separate access from a courtyard. Open plan spaces in 2 wings have the capacity to house the numbers of staff.

5. Lighting Design:
A lux level averaging 350 is the design criteria for night time illumination. Uplighting has been utilized to capitalise on the reflective properties of fabric roofs. Direct down lights are avoided to avoid glare and difficulties of access in servicing the lamps. Uplighters here are located above the perimeter wall and along the lower booms of the central truss for ease of access and remounting when the time arrives. In the daytime, a diffused level of general daylight assisted by a glowing whitish wall will greatly enhance visibility for workers having to read tags and barcodes on aluminium containers.

6. The apron and surroundings:
Intended to be fitted on an existing piece of slab, some floor areas will have to be added onto to create our footprint. The working floor within may well have to be resurfaced to provide a smooth and dust free floor. A truck holding area has been allocated to hold 24 parking lots for articulated lorries each bay having a dimension of 5 x 20m. This area is served by a new road.

AS A HAJ TERMINAL
Due consideration has been given to the final use of the relocated building as a passenger terminal, whether for Haj or other destinations, the building must be designed to accommodate people in large numbers, mechanical and electrical services and people movers such as escalators. A total of 5 aircraft stands can fit within the building perimeter. A process of retrofitting without altering the structural integrity of the building is to be facilitated. In the series of ensuing diagrams, it is demonstrated that the TCB can be fitted into a terminal building including the addition of departures floor that is structurally independent of the perimeter columns. Its sectional height will allow vehicular access around the base of the building, airbridges will lock onto the perimeter beam to link up with a departures. Large scale mechanical ducting and plant can be installed into the structure. The office extension can be cleared up into an immigration processing area with direct links to the proposed new mosque.
