Thesis Overview

1.0       INTRODUCTION            Refurbishment which is also known as renovation could be defined as the state of being restored to its former good condition.            It also main to make clean bright or fresh again or a condition supervisor to an earlier condition the microbiology laboratory was refurbished using tiles.            (Choice of Refurbishment vanguard newspaper (Egbu 1996)            A tile is a manufactured piece of hard wearing material such as ceramic, stone metal or even glass. Tiles are generally used for covering roofs floors and walls or other objects such as table tops. Another category is the ceiling tiles made from light weight materials such as perlite wood and mineral wool.
