Target Users (Target Impact Group)

Distributors / Implementing Organizations

Ethiopian Institute of Architecture, Building Construction, and City Development; University of Juba

Manufacturing/Building Method

Prefabricated components were built by local enterprises and brought to site. Outstanding materials such as eucalyptus wood and corrugated metal were purchased locally and brought to site. Students from Ethiopia, Germany and South Sudan participated in the assembly of the prototype.

Intellectural Property Type

Select Type

User Provision Model

The project is a prototype. Drawings are available (see Schematics section) to anyone wanting to build a similar structure.

Distributions to Date Status

SICU is a 1:1 single building prototype. There is no documentation of any other SICU projects yet being built.

Design Specifications

More detail about the design specifications can be found in the project brochure and Holcim Awards pamphlet:

Prefabricated concrete elements and lightweight eucalyptus frames are prefabricated and produced by micro and small scale enterprises. The flooring of the upper storey of the house is constructed with prefabricated plywood boards. SICU is a semi-complete construction where the homeowners are able to finish the building themselves. Metal connectors were used to secure the eucalyptus frames to the wooden beams. Each prefabricated building element was coded and labeled to aid the efficient assembly of the building.

Technical Support

Technical support can be provided by any general contractor since the building components are standard.

Replacement Components

Because the building is made out of materials that are available locally (in the city), replacement or new components can be purchased and easily added.

Lifecycle

Unknown.

Manufacturer Specified Performance Parameters

Manufacturer performance targets include showcasing a parallel strategy to the existing governmental housing project, researching and implementing innovative and cost efficient constructions, utilizing fast and simple prefabricated construction, and creating the opportunity for new jobs and skills.

Vetted Performance Status

The prototype and the research project was examined and accepted by academicians, researchers, and construction sector and government officials to use it as a housing solution.^{Interview with design team}

Safety

Workers are subject to the general dangers of working on a construction site including working from heights and with sharp tools. The design does not require the use of any large equipment.

Complementary Technical Systems

SICU is designed to be compatible with many types of materials as the user is given the freedom to add to it themselves. Systems that would be complimentary with SICU include latrines, dry toilets, or rainwater harvesting.

Academic Research and References

Compliance with regulations

No regulations have been cited for this product. There are likely few regulations in the informal settlements where the SICU is intended to be built.
