CHAPTER 2
BACKGROUND THE PROBLEM TO BE ADDRESSED Western Visayas College of Science and Technology is on process of development. On February 2005 we are celebrating its 100th year as a center of technological school in Western Visayas. The College of Engineering in Western Visayas College of Science and Technology, La Paz, Iloilo City was established last nine years ago. Increase of students enrolled every year greatly affects the performance of learning in the college of engineering. We have inadequate lightings in the classroom, insufficient supply of power that destruct during class hour. Also the electrical design and outlets are unorganized that keeps the students in danger all the time. Sometime we are looking an available room to use for temporary as a classroom to satisfy the convenience in learning of the students. Thus the proponents are willing to make a Proposed Electrical Design for WVCST, College of Engineering Building it includes electrical design and layout, and electrical estimates. PROJECT RATIONALE / JUSTIFICATION Western Visayas College of Science and Technology, College of Engineering, La Paz, Iloilo City is considered as one of the top performing school in the Philippines base from the recent licensure board exam. The WVCST, College of Engineering receives an applause where the pioneer batch of the Electrical Engineering Department 100% percent were passed the Master Electrician Board Exam and 88% percent of them listed in the white list as the latest electrical engineers of the Philippines. The proponents are willing to share an effort to proposed electrical design it includes electrical designs and layout, and electrical estimates for the Proposed WVCST, College of Engineering Building. The college will have a high quality standard of electrical design. It will assure the safety of the students, faculties and other personnel working in the building. It will comfort the students and faculties working here. It will increase the morale of the faculty members, employees especially the students studying here. It will increase the quality standard of education in the College of Engineering, which can produce better graduates. Because of modernized building facilities especially in terms of electrical equipment and high quality standards of materials to be used.
It’s a great honor to be involved in the WVCST College of Engineering community as a member of the Electrical Engineering Department who proposed the Electrical Design and Estimates for WVCST, College of Engineering Building which become a center of technical and engineering school in Western Visayas in the following years. CHAPTER 3
MARKETING ASPECT ASSESSMENT OF MARKET PROSPECTS The Proposed Electrical Design for WVCST, College of Engineering Building will be benefited by the students, faculty members and the people of Western Visayas College of Science and Technology La Paz Iloilo City. The Proposed Electrical Design and Estimates for WVCST, College of Engineering Building has no target market in terms of money because it is intended for better education of students in WVCST, Electrical Engineering Department. But this Proposed Electrical Design and Estimates for WVCST, College of Engineering Building shows how effective are the students of Electrical Engineering Department in making such electrical design and estimates. MARKETING PLAN For the high quality standard and modernized materials to be used in The Proposed Electrical Design and Estimates for WVCST, College of Engineering Building the proponents will provide a material needed for normal power distribution system, emergency power system, lightings, lighting control, electrical outlets, emergency cutoff switch, emergency fire alarm, communication system and other facilities and materials needed for quality standard electrical design for the electrical installations of the said proposed project. On this part of marketing plan the proponents will apply their knowledge and determination in making an electrical design necessary to have an effective quality standard of electrical design for The Proposed Electrical Design for WVCST, College of Engineering Building. These shows how talented and knowledgeable are the students of WVCST, College of Engineering, Electrical Engineering Department and through the never ending support, teaching and guidance of its faculty members. Making this design and estimates it will market the electrical engineering graduates of WVCST, College of Engineering, Electrical Engineering Department not only within the school but it makes them proud outside of the campus in the years to come.
DEMAND ANALYSIS Nowadays we are on the modern world, we are using high technological equipment and materials in our lives, and the demand is so high to balance the world we live in. Like in our Proposed Electrical Design and Estimates for WVCST, College of Engineering Building it needs for us to demand good quality standards of electrical design and materials to be used. Increase of students enrolled every year greatly affects the performance of learning in the college of engineering. We have inadequate lightings in the classroom, insufficient supply of power that destruct during class hour. Also the electrical design and outlets are unorganized that keeps the students in danger all the time. Sometime we are looking an available room to use for temporary as a classroom to satisfy the convenience in learning of the students. The demand for the proposed project is so high it’s hard to compete to develop an electrical building design without following the modern design standard. MARKET STUDY Base in our study and analysis we found out that the Proposed Electrical Design and Estimates for WVCST, College of Engineering Building could not be marketed. The special purpose of this project is intended for better education of students in WVCST. But this Proposed Electrical Design and Estimates for WVCST, College of Engineering Building shows how effective are the students of Electrical Engineering Department in making such electrical design and estimates. Maybe someday because of good quality of the building facilities and electrical design and materials used it can be marketed in terms of holding a conference in multi-media room, one of the best multi-media room in the region no other public school have this. It can also marketed in terms of considering as a tourist attraction of the school because of a very good design of the building.
