COSTS FOR BUILDING ENVELOPE
Binishells are the only building technologies, compliant to international building codes which reduce carbon footprint, construction time and improve safety. Depending on the System and a variety of site and project factors, overall construction costs may also be improved.
Binishells may reduce costs in a number of ways:
- less material (all locally sourced)
- less labor (all locally sourced)
- less construction time
The exterior shell requires:
- approx. 50% of the raw material
- approx. 1/3 of the labor
- approx. ½ of the time
Reduced Materials: Following the example of nature, Binishells use the right materials in the right way.
Like eggs, thin shell concrete dome structures distribute forces along their entire envelope. In this highly efficient structural system, forces are transferred gradually and evenly to the foundation along the entire building perimeter. Furthermore, domes typically act in compression and concrete is known to be highly efficient in compression.
Domes also provide the largest enclosed volume to exterior surface area ratio. These factors mean that safer buildings can be produced by using only approx. 50% of the raw materials.
Reduced Labor: We let air pressure do the heavy lifting.
Before it dries or cures, concrete acts like a heavy liquid. In traditional poured in place construction, this heavy liquid must be retained in expensive wood formwork which is ultimately thrown away. This results in a massive waste of time, labor, resources and money. Binishells use inflatable and re-usable fabric forms. This reduces the difficulty and waste associated with concrete construction considerably. The man-hours required in construction may be reduced by approx. 66%.
Reduced Time: Time is money.
By significantly reducing construction time, Binishells allow builders and developers to go to market faster. Significant reductions in overhead costs can significantly improve ROI.
Local Materials: Given the global ambitions of our company, we chose to use materials which are available everywhere.
Concrete is the material man makes most of. Using locally made materials reduces costs and environmental impact while enhancing local economies.
Local Labor: We designed our technologies to be quickly and efficiently executed using local labor.
The transfer of technology required for Binishells is designed for efficiency. Few special skills are required. No factories, warehouses or heavy machinery are required. These factors minimize start-up costs.
Local Codes: Concrete is known everywhere.
Another reason for choosing concrete is its prevalence in International Building Codes. Reinforced concrete and specifically reinforced thin shell structures have been codified for many years. As such, any Binishells project will benefit from the fact that the relevant codes already exist in national and international codes.
