Computer Aided Design Skills Need of Brick/Block Laying and Concreting Craft Students for Employment in Building Industry in Port Harcourt, Rivers State

Abstract

The study determined computer aided design skills need of brick/block laying and 
concreting craft students for employment in building industry in Port Harcourt, Rivers 
State. Three research questions were developed and three null hypotheses also 
formulated and test at .05 level of significance in consonance with the purpose of the 
study. The population for the study comprised two hundred and twenty five (225) 
respondents; twelve (12) brick/block laying and concreting craft teachers and two 
hundred and thirteen (213) building experts of indigenous construction firms in 
Rivers State. The researcher used the entire population of 12 for the brick/block 
laying and concreting craft teachers, since the population was manageable; whereas 
use a purposive sampling technique to select forty-four (44) building experts in Rivers 
State. The instrument for data collection was a 25-items structured questionnaire 
developed on 5-point Likert scale. A total of 56 questionnaires were administered and 
retrieved which was used for data analysis. The questionnaire was validated by three 
(3) experts and tested for reliability using the Cronbach Alpha reliability co-efficient 
(), which yielded 0.79. The data collected was analyzed using mean, standard 
deviation and t-ratio statistics which led to the following findings: that the computer
aided design skills identified in this study are needed of brick/block laying and 
concreting craft students for employment in building industry in Port Harcourt, Rivers 
State with no significant difference in the groups’ responses. Recommendations made 
amongst others are government should provide and equip computer laboratory in all 
the technical colleges in Rivers State for students to use since not all parent can afford 
purchasing it for their children and government through the school administrators
