Timber is widely used in the construction of buildings. It is a very visible component of
roof structure and it forms the structure upon which the covering is laid. The cost of
roofing is on the increase owing to the difficulties in sourcing timber in lumber forms
nowadays. In Nigeria the construction of roof for residential buildings mostly in bungalows
depend much on timber. A sample of thirty units of cost of timber roof structure from three
(3) bedrooms flat under construction was collected from Contractors and Developers.
Correlation was used to find out the cost input of timber in roof vs. the total cost of roof,
the critical value of r =.195, cost input of roof in the total cost of building, r =.090, as well
as cost input of timber in roof on the total cost of building, result shows r =-.063. Weak
strength of relationship for the first two cases and negative was seen in the last case. |
