ABSTRACT
The research looked at the effect of cost of roof on the
total cost of a building (A case study of some selected buildings in Awka
South, Anambra).It determines the attributes that effect the cost of roof, it
finds out type of roofs and their cost implications and also examine the cost
of the roof on the total cost of a building. Practicing Quantity Surveyor were
consulted and their experiences on various types of roof were shared and
compared. These experiences were used in fixing prices to the unpriced bill of
quantities given to them. Data so collected were subjected to analysis: Bill of
Quantities was used in presenting the cost of different types of roof design as
it affects the total cost.
The following
findings and recommendation were made:
1. On
cost alone, low pitch roof is cheaper to construct than a higher pitch roof. Concrete
flat roof of the same size and shape were found to be costlier than the
previously stated roof types.
2. Adequate
attention should be given at the design stage when deciding on the geometrical
shape of roofs because complex design in roof leads to in crease in cost of
roof.
3. Architect
and Quantity Surveyors should critically examine the effect of any particular
type of roof design before specifying them, especially where cost is the
critical factor in a building project.
CHAPTER ONE
INTRODUCTION
1.1
BACKGROUND OF STUDY
The overall building cost of both private and public
buildings are important as it is the summation of all the building element
cost. Douglas and Peter (1980) believe that the total expenditure on the
development of a project will be much higher than the net cost (of production)
of the building fabric, necessitating financiers and stake holder in the
industry need to know the total cost of fabric within a short time from the
giving brief while contractors are concerned on how cost is allotted within the
building.
A Quantity surveyor whose work is to cost the materials for
the building will know which material that is relevant to that particular
building, and remove those that are not relevant in order to reduce cost. He
must bear in mind that the effective development of project depends on the
estimated total cost of that project. Efficiency in execution and completion on
time would be expedited by comparison of the cost of materials, time and labor
with respect to various elements of building project especially the roof
element.
Building material and components constitute between 50-60%
of the total cost of construction input. Building materials and components for
buildings must be properly selected to comply
with standard and specifications. Many materials are satisfactory in some
condition but not in others. However their choice will be governed by the
ability of the materials to withstand the effect of climate and fulfill their
design function, with respect to maintenance and overall economic implication.
With this Architects should be careful during the design stage to avoid making
wrongly selection of material for example if wrong roof covering was selected
during design stage, the cost of the roof construction may be lower but the
maintenance cost will be higher and the roof may not last long. To achieve
quality roof, the Architects should have in mind the quality of the material
they are specifying so that the material should be such that can withstand the
effect of climate on the total cost of the building project.
The Prime Consultant who is responsible for obtaining the
necessary approvals from appropriate authorities, designing of the work and
other important steps, should ensure that his design is not for aesthetics but
for functionality because some designers may fail to realize that their design
can be too complex for site conditions and can present problems of
buildability. For example, the choice of complicated roof design or concrete
flat roof may pose more construction, maintenance problem and higher cost of
construction than design that specified simple pitched roof.
The
aim of this study is to determine the effect of cost of roof on the total cost
of a building in Awka South Local Government Area.

OBJECTIVE OF STUDY.
The
objectives of this study are:
1.
To determine attributes that affect
the cost of roof
2.
To find out type of roofs and their
costs implications.
3.
To examine the cost of the roof
elements to the total cost of a building.
1.4
SIGNIFICANCE OF STUDY
The versatility in roof design implies that roofs vary as
variety of designs thus affecting the total cost of the building. This should
therefore advise careful selection of design and materials for roof structure.
1.5
SCOPE AND LIMITATION OF STUDY
The study is based on a building design with a selected
range of differing roof designs. A comparison is thus made of the varying total
building cost to prove the hypothesis.
