Quality in Construction

The Caribbean Industrial Research Institute’s (CARIRI’s) Industrial Materials – Civil Unit held their first session for the year on Tuesday 12th April, 2016 and was aptly named “Quality in Construction”.  The session was held at the Centre for Enterprise Development in Freeport and was attended by a wide cross section of persons who actively work in the Construction sector. 

The Minister of Works and Transport, the Honourable Fitzgerald Hinds delivered the feature address at the session.  The Honourable Minister stated his enthusiasm for accepting CARIRI’s invitation to the seminar since he thought that this discussion was very important to the nation and he commended CARIRI for taking the initiative to commence it.  He stated that in adversity, we become strong and can find the opportunities for growth.
