Question 1
For each of the following statements indicate whether it is 'TRUE'OR 'FALSE'.Eachcorrect answer
carries 1 mark.
(20)
a) You are reviewing a set of blueprints for a new commercial building. The client asks if the
blueprints will include the exact colour scheme for painting the walls. A complete set of
blueprints will always include a colour scheme for painting the walls.
b) On a construction site, the client suggests that only the employer and architect are needed for
the project. The traditional set-up of the building team in the construction industry includes
the employer and architect only.
c) During an inspection, you find that a building's foundation has failed due to both underground
mining and an increase in the water table. Any foundation may fail because of subsidence
caused by underground mining and increase in the water table only.
d) The contractor installs a modern toilet system in a new residential building. The type of toilet
system commonly installed in modern residential buildings is a gravity-based flush toilet.
e) A new office building must meet design performance criteria such as fire protection, sound
control, and weather exclusion. The performance requirements of any building include among
others its appearance and sound control, dimensional suitability, weather exclusion and fire
protection.
f) Your team is using pre-manufactured components to speed up construction. System building
(Closed system Building) refers to a method of erecting a building based on the form of
construction in which the component parts of the building fabric are partly factory produced.
g) You are evaluating the structural stability of a high-rise building. The engineer discusses the
importance of the slenderness ratio for its stability. Slenderness ratio is the proportional
relationship between thickness of walls and their foundations width.

h) On a project located on a sloping site, the team suggests reducing the floor levels to fit the
terrain. In building construction working on sloping sites refers to 'reducing floor analyses.
i) After heavy use, cracks appear in several building components, indicating structural stress.
Building component will develop damages whenever the stress in the component exceeds its
strength.
j) You are managing the construction of a row of terraced houses. A wall between two of the
houses is designated as a party wall. Party wall refers to a wall separating two detached
properties that are in separate ownership such as in terraced houses.
k) The project's architectural drawings provide detailed information about the structure's walls
and doors. Architectural drawings contain information about the layout of walls, doors, and
structural elements.
I) A designer proposes using a side-hinged folding door to allow maximum doorway access. A
Side Hinged Folding door provide easy 100% opening of doorway.
m) The contractor suggests focusing on wall finishes and ironmongery as the primary building
finishes for a project. Building finishes can be categorised into groups of wall finishes and
joinery and ironmongery only.
n) A project in a region with very low rainfall is designed with a pitched roof. Pitched roof is the
type of roof suitable in plains where rainfall is insufficient, and temperature is high.
o) The floor systems in a multi-storey building must distribute their loads to columns and walls.
In floor construction, floor systems must transfer their loads horizontally across space to
either beams or columns or to bearing walls.

p) A clerk of works is a person or firm who undertakes to complete a building project in
accordance with the contract documents on behalf of an employer and has full control of all
operations on site.
q) When clearing a site, only bushes and trees need to be removed
r) Load-bearing walls are essential in the construction of traditional buildings, providing
structural support for floors and roofs.
s) In brick masonry, if the bricks are laid by the shorter face of the brick as seen in the elevation
or wall face, it is generally known as a stretcher bond.
t) A roof which slopes in four directions, is called Hip roof.
[20]
Question 2
a) A residential building is being constructed, and the initial cost estimate for roofing materials
(timber, steel trusses, and roofing sheets) was N$150,000. However, due to market
fluctuations, the cost of steel trusses has increased by 20%, while the cost of timber and
roofing sheets remains constant.
Questions:
If the steel trusses originally made up 50% of the total roofing material cost, calculate the new
total cost of the roofing materials.
(4)
b) A property developer is constructing a block of flats and estimates that the cost to build is
N$8,000 per square meter, based on current labour and material costs. The flats are designed
to have a total floor area of 1,200 square meters.

Questions:
BC55125
1. Calculate the total estimated building cost for the block of flats.
(3)
2. If the developer decides to add an additional 10% to the total floor area, how much will
the total building cost increase?
(3)
3. After completing 70% of the project, the developer faces a shortage of funds. Suggest two
ways the project team can reduce building costs for the remaining 30% without
compromising the structural integrity of the building.
(4)
c) A client has requested additional features in the construction of his office building, including
the installation of more expensive imported tiles and custom lighting fixtures. The original
budget for tiles was N$100,000, and for lighting, N$50,000. The imported tiles will cost
N$180,000, and the custom lighting fixtures N$80,000.
Questions:
1. Calculate the total cost overrun for the tiles and lighting fixtures.
(3)
2. If the client has a strict budget and can only increase his total cost by N$50,000, what
adjustments could you propose to meet the client's budget?
(4)
3. As a project manager, discuss the potential long-term implications (financial and time-
related) of agreeing to the client's requested changes.
(3)
b) Outline the six (6) functions of external walls of a building.
