THE EFFECT OF COST OF ROOF ON THE TOTAL COST OF A BUILDING. A CASE STUDY OF SOME SELECTED BUILDINGS IN AWKA SOUTH- ANAMBRA STATE
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:
- 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.
- 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.
- 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.
- To improve on duration of roof covering, the material should be adequately protected from rust by use of anti- rust and in the case of aluminum, it must be stucco embossed or baked but not spray painted.
