THE ROLE OF BUILT ENVIRONMENT PRACTITIONERS IN THE IMPLEMENTATION OF THE CONSTITUTION OF KENYA.

THE ROLE OF BUILT ENVIRONMENT PRACTITIONERS IN THE IMPLEMENTATION OF THE CONSTITUTION OF KENYA.

The new constitution clearly states that every person in Kenya has a right to adequate housing:

Economic and social rights

Section 43.
(1) Every person has the right—

(a) to the highest attainable standard of health, which includes the right to health care services, including reproductive health care;

(b) to accessible and adequate housing, and to reasonable standards of sanitation;

(c) to be free from hunger, and to have adequate food of acceptable quality;

(d) to clean and safe water in adequate quantities;

(e) to social security; and

(f) to education..

For Kenya to provide adequate housing to its citizens, the Built Environment practitioners will have to think outside the box and provide a sustainable solution.
Demand for housing in Kenya is estimated at a deficit of between 100,000 to 200,000 units per year. This demand has resulted in high housing prices hence unaffordable and unsustainable to many Kenyans.

NEW BUILDING TECHNOLOGY

Use of new building technology that lowers the cost of construction will be one way of making housing accessible to all in Kenya. The new Building code should allow for other methods and construction materials such as prefabricated housing ,Structural Insulated Panel housing and adobe construction. This will open up completely new industries as practitioners in the built environment come up with new building materials and methods of construction as they experiment with the already existing ones such as prefabricated housing.

TECHNIQUES

Building technology techniques that use locally available materials to construct at a much lower cost will come a long way in ensuring adequate housing to all Kenyans. In recent years, we have seen several Kenyan architects who have come up with unique methods of lowering construction by use of locally available materials with unique technology.

A good example is Nakuru-based Architect Dumas’ NewBuild technology available at Ministry of Housing that reduces use of Reinforced Concrete on masonry house construction.

Use of Information Technology[ IT ]

IT can also lower the cost of construction in that once creative Built Environment practitioners set up web applications that can enable people easily access information regarding material costs and be able to tender out their house designs to potential contractors, this will lower the cost of construction in the long run.

A good example is Nairobi –based QS Nahinga’s http://www.ujenzibora.com/ who has developed an application that allows for online tender submission and quoting.

Other online IT methods such as online consultancy that reduces the frequency of face-to –face meetings will eventually reduce the cost of construction. The never-ending Nairobi traffic jams usually result to a lot of time and fuel wastage which is added upon the cost of consultancy hence high housing costs. These IT interventions might not seem to save a lot of money initially due to the fact that very few Kenyans have access to the internet but in the end, once more research is put into them ,the net result will be a major reduction in the overall cost of housing as seen in new technologies such as M-Pesa.

CONCLUSION.

There are other interventions in lowering the overall housing costs such as provision of lower mortgage and provision of infrastructure.

Solutions to lower the cost of housing in terms of use of building technology and IT lay squarely in the Built Environment practitioner’s court hence such interventions will go a long way to ensure that there is a reduction in the cost of housing in Kenya now that housing is a right to Kenyans.

J.F Kennedy’s[ 1917-1963]- famous words conclude:: “And so, my fellow Americans: ask not what your country can do for you – ask what you can do for your country.

My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man.

Finally, whether you are citizens of America or citizens of the world, ask of us the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on earth God’s work must truly be our own. “

THE SWISS KNIFE HOUSE DESIGN BY A4ARCHITECT.

THE SWISS KNIFE HOUSE DESIGN BY A4ARCHITECT.

As the name implies, this design behaves similar to the swiss army knife in that it has multiple uses all wrapped up in one.

It begins with a 2 bedrroomed house which can change into a 3 bedroomed bungalow which can further change into a 4 bedroomed maisonete which has an added ability to change into 2 separate 2 bedroomed houses or 1 no. 3 bedroomed house with another 2 bedroomed house upstairs.

The firm of http://www.a4architect.com has come up with this marvelous design that takes flexible house plans to new levels.

Advantages.

This flexible house plan design has several advantages:
1. The occupant can decide how much space they want to use and rent out the space that is not currently in use such as upstairs 2 bedroomed house.

2. 2. The occupants can decide to sell off the upstairs 2 bedroomed house through use of the Sectional Property act Title.

3. 3. The house owner can build in phases depending on his/her budget beginning with the ground floor until 1st floor.

Cost of Construction.

The cost of construction is also as flexible as the swiss army knife.
A4architect gives house owners a wide range of choice of materials and construction technology to choose from.
Use of natural local materials for construction coupled with low-cost housing technology reduces by over 50% the normal cost of construction.

To quote H.E President Mwai Kibaki during a recent seminar on Mortgage cost reduction organized by Shelter Afrique bank, he said that ‘ our continent has rich traditional architectural designs. In doing this, we must focus on the use of available local materials. These materials should be transformed through use of modern technologies that are making housing construction more affordable.” Source: http://www.statehousekenya.go.ke/speeches/kibaki/june2011/2011140601.htm

For those who would require imported construction materials, we also provide for this specification in our design and the costs of construction are adjusted to reflect this.

H.E PRESIDENT MWAI KIBAKI’S SPEECH DURING THE 30th AGM OF SHELTER AFRIQUE BANK AT KICC, NAIROBI-14TH JUNE 2011.
MORTGAGE FINANCE FOR INCREASED ACCESS TO HOUSING IN AFRICA.

Present:
H.E PRESIDENT MWAI KIBAKI
VICE PRESIDENT KALONZO MUSYOKA E.G.H, M.P
MINISTER FOR HOUSING-Hon. Soita Shitanda, E.G.H,M.P.
MINISTER FOR LANDS AND HOUSING-UGANDA-Hon. Daudi Migereko.
CHAIRMAN OF SHELTER AFRIQUE BANK.

ARCHITECTS .

Hon. KALONZO MUSYOKA’S SPEECH.

Vice President Hon. Kalonzo Musyoka began his speech by jogging peoples’ memories on the fact that in the year 1987, he was honored to lead the Kenyan delegation to the 6th AGM in Kigali, Rwanda. During the AGM, he says that Kenya did not hesitate to host the Headquarters in Nairobi.

Hon. Kalonzo Musyoka said that he was also honored to lead the Kenyan delegation to Vienna in 1996 where after Kenya made a decision to include shelter an issue of Human Rights.

He said that the new Kenyan constitution now makes shelter a basic human right.
He then invited H.E President Mwai Kibaki to give his speech.

H.E PRESIDENT MWAI KIBAKI’S SPEECH.

H.E President Kibaki welcomed all to the meeting on behalf of the people of Kenya.
He noted that the theme of the meeting was Mortgage finance for increased access to housing in Africa.
He said that the theme was timely to address the housing shortfall in Africa due to rapid urban growth. He said that Africa is currently experiencing 5% annual urban growth rate which is the fastest in the world. This has resulted in environmental degradation and the onset of slums.

He said that Africa must invest in more resources in Housing. He stressed that innovative housing finance strategies are critical. The cost of Housing should reduce.
He noted that mortgage financing is expensive, risky and only for the rich and Africans must make property financing affordable to low income people.

He hoped that the meeting will come up with a concrete proposal to unlock mortgage to enable people to access housing.
He noted that since 1982, Shelter Afrique has played a crucial role in facilitating development of housing mostly in the middle income households e.g. in Kenya, Shelter Afrique has funded over 86 projects at a cost of 111 million USD which has resulted to an increase in Kenya’s economy.

He said that use of locally available construction materials should be used with modern technology to make construction affordable.
He said that the Banking Act has been amended to accommodate extension of credit to the real estate sector. E.g. mortgage companies are now allowed to operate current accounts to mobilize deposits and Banks can advance up to 40% of their total deposits up from 25% for investments in real estate.

Conclusion.

H.E President Kibaki said that cost of borrowing money to build a home was too high, hampering Kenya’s development. He challenged Shelter Afrique to find ways of reducing this and requested all present to focus on this dimension.

How To Build A Raft Foundation In Silty Soils

How To Build A Raft Foundation In Silty Soils

Author: Andrew Karundu

Silty soils are unstable and have very low safe bearing capacity. This means that they cannot safely carry foundations. Due to there unstable nature, different foundations are used. This foundations are either piles or rafts. The raft foundation involves bulk excavations. Other soils that may require total bulk excavations are cotton soils. The excavations allow for the loose silt to be removed. This is normally found on areas near water bodies, rivers, bottoms of valleys and swamps. The depth will vary according to the topography of the land.

Raft foundations cover the entire area of the building. This means that the total surface to be covered is built on this foundation. The depth of excavation should be determined on site. The foundation should be cast on a firm surface. This is usually a hardcore surface. The depth of concrete is one foot over general surfaces. to be located, the depth is one and a half feet. The whole base should be like a floating mass of reinforced concrete.

The raft foundation commences by marking out the desired building layout. After checking the depth of silt from a trial pit., excavation commences. After it is complete, a compactor is used to form a flat hard surface. Care should be taken to avoid water in the pit. The firm surface is then compacted to the approved levels. When this is complete, Hardcore is then added to the pit. This is compacted in stages of one foot. A two feet depth is ideal.

After the hardcore is in place, The areas to have the walls are marked out. Any walls that are load bearing are clearly marked out. Hardcore is then removed to a depth of one foot and two feet wide. Blinding and a damp proof membrane are laid over hardcore. A mesh reinforcement is laid over at a height of six inches. Concrete is then poured onto the hardcore. After curing for a week, the walling may now commence for the actual building.
