The Quantity Surveying undergraduates of the Intake 36 embarked on their second field visit on 24th October, 2019. This time it was to the Water Supply Project (Stage IV), Matara. During the visit, they were able to derive a rich practical knowledge on theoretical learning of Construction Technology Module II by observing a salinity barrier which is used to purify water from River Nilwala. The undergraduates were accompanied by their module lecturer Engineer M. W. P. Chathurika and the site supervisor Engineer V. Wanigasinghe who enhanced their knowledge by delivering them an onsite briefings on piling systems and dewatering methods used in a water supply project. This field visit was facilitated by Engineer I. D. WIjesiri, the Project Director of Water Supply Project IV, National Water Supply and Drainage Board, Matara.
