Introduction 

Portfolio Review will briefly summarize the entire learning experience for BBY21505 Building Services Course 1. Starting from Project Information and the Commissioning Process. These two topics will explain the results of the Building Construction Technology Bachelor Program Industrial Visit to Kluang Railway Station, which took place on May 23, 2023, last Tuesday. Through the results of the visit, students were given the task of completing and producing Case Study 1 in more detail, namely Project Information and Commissioning Process. Kluang Railway was selected as a modern building because it was built with elements of Green Design, applied new technology in construction, and used an advanced commissioning system. In addition, the review portfolio explains more simply about Building Services Management where the information and learning outcomes of each chapter are included in a mind map for better understanding. A video portfolio review is also included where it contains reflections related to the subject studied, assignments done individually and in groups, as well as understanding throughout the lessons in the BBY21505 Building Services 1 Course.
