Thesis Abstract
<p> <b>ABSTRACT</b></p><p> The study examined the effects of faulty design and construction on the maintenance
of building. A survey of randomly selected samples of 20 builders and 15 architects
were conducted. Questionnaires were used to collect data from Architects and
Builders. The survey included 11 groups of defects and sub defects in each groups.
The predominant severity effects of each defects was assessed and ranked based on
the severity index as ranked by both the Builders and the Architects. The results
shows that 7 defects were rated as most severe, 54 as moderately severe and 6 defects
as slightly severe defects. The results also show that increase in maintenance work is
the most predominant effects on building maintenance among other factors of defect
with an index value of 100.00 as perceived by both the rank of the Architects and that
of the builders. The research however includes a hypothesis that Architects and
Builders generally agree on the ranking of the severity defects which was tested and
proven to be true. The study concluded that there should be a design review before
finally approving the design for construction; maintenance expert should not be
overlooked in the planning stage of the project and most importantly the employment
of professionals for any building projects.

Thesis Overview
<p>
<b>1.0 INTRODUCTION </b></p><p><b>1.1 BACKGROUND OF THE STUDY</b></p><p> 'To fail to plan is to plan to fail.'— (Wood, 2003)
The essence of all result-oriented work may be identified in this quotation. In the
context of design one can adapt this phrase to, 'if a designer fails to plan well the plan
will turn out badly'. In understanding this phrase one can use a law of physics as a
metaphor. Newton's third law of force is 'For every action there is a reaction'. For
designers this law could be interpreted as 'for every design decision/consideration
(action) there is a consequence (reaction)'. As such this research tries to explore the
actions of design and the consequence of their actions. </p><p>The relationship between design, construction and maintenance is closely related but
not easily distinguished. (Maisarah, 2012) explained the vital role of design in the
early stage of project management. They stated that a functional design can promote
skill; economy, conveniences, and comforts while a non-functional design can
impeded activities of all types of detract from quality of care, and raise cost to
intolerable levels. </p><p>A typical saying by Vonnegut: everybody want to build and nobody
want to do maintenance. In Nigeria building design are copied from other countries
without considering the conditions that lead to such design, hence maintenance
experts are seldom included to advice on maintenance efficiency of such design. In a
related development (Iyagba, 2005) reveal that there are substantial numbers of
people who do not know the meaning of maintenance. The mistakes most designer
made is believing that a building that is design with the best aesthetics materials
requires little or no maintenance, but such notion or argument are wrong because The maintenance of a building begins after the construction is completed (Haniff, 2007).
(Eizzatul, 2012) observed that the maintainability aspect at the design stage is often
ignored and this has contributed to future problems when implementing maintenance
work. He further explained that this happens when the aesthetics value has become
more important in the design of asset, besides the design factor, site selection,
apparatus, tools or facilities to maintain the asset are hard to obtain or very costly.
According to (Rozita, 2006) the effectiveness of the building is not dependent on its
aesthetic value but on the ability to perform maintenance works on the building in the
future. Just like the military slogan that if you fail to plan, and then you are planning
to fail. That is, if a building is design and constructed without any plan for
maintenance the building is hovering towards failure. </p><p>According (Norhanizaetal,
2007) if the designer failed to plan well the entire plan would also fail. Every decision
made during the building design and construction has its own impact, too often the
professionals that constructs and design don‘t worry whether the building they design
and build will work properly, their major concern is just to complete the project and
move to the next job while the consequence is left for the client to handle. The effect
of faulty building design and construction has become one of the major issues in
maintaining building in Nigeria. Nigeria has a population estimated to be around 150
million which has the largest black populace in the world and as such new building
are being built daily to accommodate the demands of the teeming population, this has
lead to the desperation of every single individual to have a building of his own , the
consequence is that an inexperience designer is given a contract to design and same to
another to construct in a short period of time which will result in many defects
especially during the design and construction stage and this will inevitably result in
high maintenance cost. (Abdulmohsen and sadi, 1997) stated that the increase in
3
maintenance cost is attributed to the failure of the building design. If we compare the
production of as cars, for example a car is designed and then built; it is tested
exhaustively, fault identified and then rectified. If we relate this to building work, we
need to construct a building, test if overtime and then demolish and rebuild, removing
all problem in the next design. </p><p>Faulty construction also accounts for many building
failure, if a new copied design has not been specified or built previously(most
especially designed copied from abroad) the builder will have no experience of this
design and may build it incorrectly resulting in high cost of maintenance with inherent
defects. It is therefore sacrosanct for both the designer and the builder to consider the
importance of maintenance at the onset of the design because decision made at the
planning stage have a large effect on the maintenance of the building and the cost. It is
most times worry some that most building expert that suppose to educate the public
on the importance of building maintenance will say age building result in high cost of
maintenance.
To avoid the implication of design faults on the need for future maintenance, constant
research and close observation of existing methods of design and construction practice
are needed. In addition, it requires more international forums to address and exchange
the issues and experiences seen in different parts of world. In Singapore, an analysis
of defects in wet areas of buildings by (Chew, 2005) reported faults in design, the
construction phase and material selection. The main sources of defects were the
mistakes made at the design stage, construction phase, maintenance practice and in
materials selection. The defects that resulted from these failures included tile
debonding, mastic failure, the staining of tiles, cracking, water leakage through
cracks, water leakage where pipes passed through walls, paint defects, water ponding,
spalling of concrete and unevenness of tile surface and poor pointing. This long list of
4
defects is only those found in the wet areas of buildings which constitute only a small
part of the total building. This alarming amount of design faults also creates an
opportunity for similar research in other parts of the building as well. </p><p><b>1.2 STATEMENT OF PROBLEM</b></p><p>Nigerian is a rich developing country with huge capital resources. It is developing
very fast in every area including building construction. Public and private sectors have
initiated the need for large and complex construction projects. Meeting the high
demand of both parties in a short time, it is expected that many errors and defects
have concerned during the design and construction stages which will result later in
high maintenance costs and breakdown of structural component. </p><p>Despite the various
strategies being adopted by the government for the maintenance of those facilities, the
buildings remain a home for defects that should have been avoided if proper
feasibility planning on maintenance has been given cognizance right from the design
and construction stage of the project. This has led to unnecessary expenditure from
the various authorities in carrying out remedial work to curb the effects. (Brennan,
2000) opined that the main purpose of maintenance of property is essentially to retain
it values for investment, aesthetics, safety and durability with a view to ensuring that
the property is continually used for habitation and to satisfaction of the owner.</p><p> It was
even observed that majority of the new construction were being built up with defects
which later transpire into substantial expenses on maintenance. </p><p><b>1.3 THE PRESENT WORK</b></p><p>This present research is concerned with the investigation of the effects of faulty
design and construction on Building maintenance. Questionnaires were used to collect
data from designers and Builders. The predominant severity effects of each defects
was assess and rank based on the severity index as ranked by both the Builders and the designer using SPSS 20. This was used to determine whether there is a correlation
between designer and construction professionals. </p><p><b>1.AIM AN OBJECTION </b></p><p>The aim of this research is to investigate the effects of faulty design and construction
on Building maintenances.
The specific objectives of this research are: </p><p>i. To identify the building defects caused by faulty design and construction on
building maintenance</p><p> ii. To determine the severity index of all defects identified and classify them by
severity using SPSS 20. </p><p>iii. To determine the severity index for each defect within the group and classify
them by severity using SPSS 20. </p><p>iv. To assess the effects of the building defects caused by faulty design and 1.6 </p><p><b>1.2 SGNIFIANCE OF THE STUDY</b></p><p> Previous research has shown that the cost of maintaining a building usually involve
large amount of expenditure which most times surpass the cost of building structure
itself. Therefore, design and construction play a vital role in deciding if defect will
transpire later in the building. Hence, by getting it right from the onset of the building
can go a long way in minimizing mistakes and error that might occur during
construction. </p>
