PREFACE
The B.Sc Engineering degree course of the University of Moratuwa extends over a period of four
years with a 24 weeks training period. This report is prepared for the completion of the 24 weeks
training period at Sarvodaya-Vavuniya Quarry(A) & North Road Rehabilitation Project(B).
The construction has being carried out by Access Engineering Ltd. Consultant of North Road
Rehabilitation Project is Central Engineering Consultancy Bureau (CECB).
During the training period I gained in many practical aspects of the theories, which I had
learnt in the university. I have briefly discussed in the report, the important information I
gathered during the training period.
In the first chapter I mentioned the introduction of Access Engineering Ltd, policy
statement, completed projects, present performance and other services. I mentioned details about
special achievements, divisions & subsidiaries of the organization. In this chapter I have
discussed about usefulness to Sri Lankan society, weaknesses of ACCESS, suggestion to
improve its performance. In the chapter two I discussed about quarry, crusher asphalt plant and
lab testing. The final chapter is where I have stated my conclusion which includes the
suggestions to improve the industrial training programmed.
