Cost per square meter | Building Cost | Construction cost


The shape of a building has an important effect on cost. As a general rule the simpler the shape of a building, the lower will be its unit cost. Let us illustrate this as follows:  This determines the cost per square meter of building

BUILDING SHAPES
Regular shapes in contrast, become more expensive the longer and narrower they are planned. This can be illustrated by the following examples of a square and rectangular building with the same floor area.

Cost Per Square Meter



BUILDING A           BUILDING B
Example of how building cost per square meter can vary

BUILDING A
Area on plan = 400m²
Length of walling = 80m
Assume 3m high walling @ Currency 200.00/m²
Then cost/m² = 80 x 3 x 200 ÷ 400 
= Currency 120.00/m² - cost per square meter
 
BUILDING B
Area on plan = 400m²
Length of walling = 208m
Assume 3m high walling @ Currency 200.00/m²
Then cost/m² = 208 x 3 x 200 ÷ 400
= Currency 312.00/m² - cost per square meter
 
The length of Building B thus resulted in an additional expense of Currency 76,800.00 over that of Building A influencing cost per square meter
 
Both plans have exactly the same floor areas, yet BUILDING B is far more expensive due to the shape of its design. Reasons for the increase in costs are:

  1. Building B has a higher perimeter/floor area ratio (to be discussed in more detail later) and requires 6% more external walling to enclose the same floor area than A.
  2. Setting out costs will be increased by as much as 50%.
  3. Excavations will cost between 6% and 20% more.
  4. Drainage costs will increase by approximately 25% due to the extra manholes and extra length of piping needed.
  5. Additional costs will also result from other elements of the building such as the walling and roofing due to the work being complicated by the shape.
It can therefore be concluded that the irregular shapes of buildings add to their overall cost.

Frugal Innovation In Africa - moladi FRUGAL INNOVATION IN AFRICA  FRUGAL INNOVATION IN AFRICA - moladi Moladi: Affordable houses in South Africa In many African countries, housing is one of the most sensitive issues affecting the lower income groups. In South Africa for example, close to 13% of the 14.3 million households are informal dwellings (Statistics South Africa, 2011). The term “informal dwelling” is often used in South Africa to designate shacks, corrugated-iron structures and other makeshift shelters. The above statistics represents about 1.8 million households (between 7.2 and 10.8 million people). Informal structures are often made of highly combustible materials such as wood and cardboard which pose serious safety and environmental concerns. The structures are easily damaged and exposed to the external elements meaning that people often live in damp, very hot or very cold conditions. The other concern is inadequate or lack of sanitation and running water which constitute

BUILDER OF THE FUTURE

THE BUILDER OF THE FUTURE The Builder of the Future Moladi construction systems has developed a way in which houses and social infrastructure can be built faster and cheaper, without jeopardising the structural integrity of buildings. by Glenneis Kriel - Finweek   While most other industries have undergone tremendous change, the building and construction sector has seen little new technological breakthroughs over the past fifty years. That was until Hennie Botes, the founder of Moladi , came along.   Realising the struggles of the poor in getting good quality housing, already in the 1980s, Botes decided to do something about it. His solution was the development of a whole new building system, which he named Moladi. The system replaces the cumbersome bricklaying process with an approach similar to plastic injection moulding.   A “mould” is produced by training local unskilled labour to assemble reusable plastic injection moulded panels, commonly known as formwork. The formwork is erect

At the centre of it all was Mineral Resources Minister Mosebenzi Zwane, who, while he was MEC for human settlements, sanctioned the payments of hundreds of millions of rands to companies that had not done any work for the government. Now new MEC Sisi Ntombela's department is suing the 106 contractors, including Motsoeneng and Nozuko Mbalula in their capacities as trustees, and materials suppliers that received upfront payments to
