THE IMPACT OF GOOD DESIGN AND CONSTRUCTION WORKS IN MINIMIZING MAINTENANCE PROBLEMS

Introduction
Over the years, poor design and poor construction works have caused so many problems as far as erection of good structures and the maintenance of such structures is concern. The problems emanating from poor design and poor construction works have caused so many people to loose the faith they once had in the building and construction sector of the economy. Due to the non-challant attitude and the negligence of some professionals in the building industry, buildings are wrongly designed and construction works on an on-going project are wrongly executed, that is construction works are not executed according to the standard in the Building Code. The impact good design and construction works is therefore paramount in the construction and the maintenance of buildings .It has been observed that one of the major problems associated with maintenance in our society are as a result of our poor maintenance culture It is therefore important to explain maintenance as a concept in details. Building maintenance is a major activity in most countries. Any reduction in resources applied to building maintenance will have a visible effect on the economy. Few years ago, a rapid growth of housing construction clearly appears as a part of the country development. The number of modern houses increases and more houses are being constructed. As a result, more maintenance work is required in order to cope with this type of construction. Due to the growth of housing with the lack of building Standards, more maintenance, rehabilitation, and renovation work have become necessary to ensure the serviceability and safety of the constructed houses. In addition, the existing houses need to be sustained as long as possible. Therefore, ways must be found to reduce the maintenance cost works due to ageing of the buildings while keeping the same quality

BUILDING MAINTENANCE OVERVIEW

Maintenance assists retaining economic life of buildings. Moreover, it is a productive activity both at the private and the national levels. At the private level, proper maintenance leads to lower depreciation costs (due to longer economic life) and consequently leads to higher profitability. While at the national level, proper maintenance leads to lower expenditures on replacement. Thus, allowing more expenditure on expansion into new productive investment The Committee on Building Maintenance in British defined maintenance as: “Building Maintenance is the work undertaken in order to keep, restore or improve every facility, i.e. every part of a building, its services and surrounds to a currently acceptable standard, and to sustain the utility and value of the building” In addition, maintenance is defined in the British Standards (BS 3811:1974) as “A combination of any action carried out to retain an item in, or restore it to an acceptable condition”. A more functional definition is that “Maintenance is synonymous with controlling the condition of a building so that its pattern lies within specified regions”. Moreover, building maintenance cost can be defined as the cost of any actions carried out to retain an item in, or restore it to an acceptable condition but excluding any improvements other than those necessitated by inability to replace obsolete materials or components. The objectives of building maintenance are therefore : (Alner and Fellows, 1990):

• To ensure that buildings and their associated services are in a safe condition. • To ensure that the buildings are fit for use.
• To ensure that the condition of the building meets all statutory requirements. • To carry out the maintenance work necessary to maintain the value of the physical assets of the building stock. • To carry out the work necessary to maintain the quality of the building.

Maintenance can be done in different stages. Each stage will have different characteristics. Liska`...
