Ethical standards and social equity
Davy Sukamta&Partners Structural Engineers UPH 2014
Definition – Ethical standards and social
equity – People
The project must adhere to the highest ethical
standards and support social equity at all
stages of construction, from planning and
building processes to long-term impact on the
fabric of that community. The project has to
provide an advanced response in terms of
ethical and social responsibility.
Adherence to ethical standards in all phases of
the project's life cycle.
Contributions to the formation of socially
viable environments and the values of
communities.
Participation of stakeholders (client, users,
neighborhood, local authorities, non-
governmental organizations and others).
Quality of working conditions in the suppliers'
workshop, on site and during operation
(compensation, safety, basic needs, gender
issues).
Political transparency and correctness
Especially in poor countries,
sustainable construction means
building to supply urgent and
basic needs: shelter, water,
schools, access to goods and
services, and medical care. In
other countries, affordable
housing is a main issue. In still
others, the problem is wasteful
and excessive consumption,
which might be financially
affordable but is irresponsible.
Leaving sufficient materials and
resources for others, including
future generations, is a moral
duty.

Clothing factory in Sri Lanka – MAS Intimates Thurulie
This clothing factory in Sri Lanka is a
visionary departure from standard
approaches. It claims to be the world’s
first clothing factory powered solely by
carbon-neutral sources, with the
payback period for the extra cost of
making the building sustainable of only
five years.
The health and well-being of staff is
central to the design of the factory. The

The health and well-being of staff is central to the design of the factory. The building offers a comfortable,
healthful, and attractive indoor environment for all users. As part of its service to employees, the plant
provides bus transport to and from the factory for staff, as well as on-site meals, medical care and banking.
The production floor is divided into separate areas where works collaborate in autonomous teams,
enhancing productive and employee satisfaction. The eco-factory is an ethical response to consumers who
called for stronger environmental stewardship. The beautiful and stimulating environment is uplifting: the
factory is a place where people are considered with respect and dignity.

Incremental housing and decentralized sewage
infrastructure improve lives of urban poor
A community cluster-based
sanitation system won the “Next
Generation” 3rd prize for Asia
Pacific in 2011. Since then, the
prize money from the Holcim
Awards competition was used to
develop the project: to survey
the site, engage with an
engineer, mobilize the
community and support the
project author for more than a
year.
The aim of the project is to improve people’s lives through the provision of sanitation
which is at the core of dignity and health. The next phase of the project will involve
retrofitting households to accommodate the new toilets in Savda Gherva. The aim is to
implement a viable system that will become a transferable model sanitation solution for
unconnected (off-grid) low-income settlements, especially suited to the context of slum
redevelopment and upgrading.

Economic performance and compatibility –
Prosperity
Definition – Economic performance and compatibility – Prosperity
The project must prove to be economically feasible and innovative as far as the deployment of
financial resources is concerned. Funding must promote an economy of means and be compatible
with the demands and constraints encountered throughout the construction’s life span.
Innovative models for financing.
Financial resources over the project’s life cycle and their regional impact.
Flexibility with regard to future changes (user, ownership, laws and regulations).
Robustness to economic conditions (interest rates, taxes, inflation).
Economy of resources deployed in construction.
Through efficiency of design, construction, maintenance, operation, reuse, and recycling, sustainable
construction seeks feasible projects that provide long-term economic benefits for owners, users, and
communities. Such benefits can take many forms besides profits or lower costs, for example:
strengthening the economic base of a region, boosting the local economy, giving residents more
control over their housing costs, or even giving people a financial base.
Innovative deployment of financial resources, durability, adaptability, lifecycle cost planning, “free”
low-tech natural resources, and other attributes can work together to make sustainable construction
not only financially feasible but the preferred choice and a sound long-term investment in the future.

High-efficiency concrete formwork technology
The Wasteless Free-Form Formwork construction technology combines existing processes
and materials in a new way to fabricate non-repetitive free-form cast-on-site concrete
structures using re-usable and digitally-fabricated wax formwork. The approach enables
highly accurate, complex and free-form geometries of contemporary architectural production
to be fabricated at lower cost.

High-efficiency concrete formwork technology
Zurich, Switzerland The construction technology combines existing
processes and materials in a new way to fabricate non-repetitive free-
form cast-on-site concrete structures using re-usable and digitally-
fabricated wax formwork.
The proposed technology developed by Gramazio & Kohler, Architektur
und Digitale Fabrikation – ETH Zurich, is based on a concept of mass
customization rather than mass production. This means that there is no
inherent difference in costs whether all elements fabricated are the same
or different. The technology also focuses on economic feasibility in
comparison to the state-of-the-art for free-form geometries, while
implementing a completely waste-less, cyclical process, meaning that
production costs go down, as usage increases.
The technology enables complex and free-form geometries of
contemporary architectural production to be fabricated using designs
that are highly optimized in terms of material consumption, energy
efficiency, and usability.
