1. TRONCO BUILDING SUPERSTRUCTURES IN HAITI
RAPID DEPLOYMENT IN TERMS OF PERMANENT, RESIDENTIAL/NONRESIDENTIAL CONSTRUCTION PROJECTS AT MULTIPLE LOCATIONS ON A SIMULTANEOUS BASIS GENEVA, OCTOBER 2010

2. Tronco Superstructures
Opening new markets so far beyond reach for high quality building construction

3. Speed and simplicity
The simplest/fastest way to erect permanent buildings anywhere, including in the middle of nowhere.

4. Standard, high quality of construction
Assembling locally/custom-made components into superstructures of the same quality, irrespective of whether built in the city or in the most remote locations.

5. Basic material and components
Steel or aluminum are brought to the construction site in the form of coiled strip material and special clips or connector elements.

6. Logistics (I)
Tronco’s manufacturing equipment (tube-forming machine or “TFM”, compressor, generator and complementary tools) fits easily into special 40-foot containers, which then become autonomous production plants. TFMs are transportable by boat, truck or aircraft to the construction sites.

7. Basic Component
The system’s basic component is a metallic log called “metalog”® . Metalogs are custom-made at any job site from coiled strip material, with attached connector elements at one or both their ends.

8. Logistics (II)
One cubic meter of coiled material allows for the onsite fabrication of the metalogs required to build up to 350 cubic meters of enclosed areas, including walls, upper floors and roof.

9. Easy On-Site Component Production
Metalogs are custom-made at the construction site and, when combined with a limited number of pre-manufactured components, can be rapidly assembled into up to 3-story building superstructures (walls, upper floors and roofs) by a small team of mostly locally hired, unskilled workers.

10. Variety of architectural solutions
Tronco is not a prefab system that would involve pre-dimensioned building components. Its superstructures can all be designed and built on a case-by-case basis.

11. Exterior cladding
Once assembled, the superstructure may receive optional exterior cladding of insulated "troncopanels” and plaster finish. Troncopanels are made of high-density polystyrene. They are flat on one side and show a relief on the other side, which is the exact counterpart of the relief of the tubular wall or roof onto which they are directly applied.

12. Conventional look
Once the metallic superstructure receives its wall cladding, a building may end up looking like conventional construction.

13. Interior cladding
Troncopanels can also be used for interior cladding. As an alternative, gypsum board (drywall), fiber-cement or any other interior panels may be installed on walls and ceilings directly screwed to the metalogs (using self-tapping screws). Another option is to attach expanded wire mesh (wire-lathe) to the metalogs followed by plaster

14. Comfort
Tronco superstructures are notoriously energy efficient. The insulation capacity of the air chambers inside the walls may be complemented with the insulation of the claddings.

15. Versatility
Custom-designed buildings with cement-stucco, brick veneer or wood cladding blend in with most architectural styles, whether traditional or contemporary.

16. Superstructures before cladding
Tronco superstructures convey an image of neat, high-tech robustness. Depending on type of project, they may not require wall cladding.

17. Superstructures with wall cladding
Once the metalogs are hidden from view, a Tronco superstructure may look like a conventional building.

18. Superstructures with no wall cladding
Depending on the type, use and location of a building, the continuous metalog wall and ceiling surfaces may be left without cladding, or receive a coat of elasthomeric paint for a colorful look.

19. Rural shelter (I)
Small and simple superstructures do not necessarily require cement slab foundations prior to erection, which renders them particularly versatile for remote locations, where even pouring a cement could be a problem).

20. Rural shelter (II)
Superstructures can be built on a do-it-yourself basis by end-users. A liquid membrane may easily be applied by the same end-users over the roof’s metalogs to render such structure habitable. Cement or adobe wall cladding, a hardened floor, prefab toilets and additional rooms may all be added at later stages.
