SCHOOL OF ENGINEERING AND ARCHITECTURE (SEA)
Meru College of Technology (MECOTECH) identified a niche in automotive and later Building Construction courses since its establishment in 1984, offering the courses at Certificate and Diploma levels. In 2008, the government of Kenya upgraded the then Meru College of Technology (MECOTECH) into a University College and named it Meru University College of Science and Technology (MUCST). During the transition from a college of Technology to a University College, Engineering courses were housed in the Department of Science, Mathematics and Engineering. When the University was awarded the Charter in 2013, a Department of Engineering was then established in the School of Information Technology and Engineering (SITE). In order to exercise that mandate great effort was put to ensure that Engineering degree programmes were introduced to run concurrently with certificate and diploma courses. The first Engineering degree programmes were introduced in September 2014. The programmes which were introduced and are currently running comprise of:
- Bachelor of Technology in Civil Engineering
- Bachelor of Technology in Electrical Engineering
- Bachelor of Technology in Mechanical Engineering
These are 4-year programmes whose graduates will serve the Engineering industry as engineering technologists. The introduction of these programmes justified the creation of Department of Engineering which was domiciled in the School of Information Technology and later led to establishment of School of Engineering and Architecture (SEA) in July 2016.
SEA’s vision is to be a leading centre of excellence in Engineering and Architecture. In this regard we focus on furnishing our students with the finest instruction and strong foundations in Engineering and Architecture. Our core values which are integrity, commitment, academic and research excellence, professionalism, innovation, teamwork, equity and social justice and customer responsiveness are our guiding pillars which the School fraternity strongly believes in.
The aspiration of Meru University of Science and Technology is to expand further the training of Engineers because there is great global demand for them.
Recently the School received modern training equipment from the Government. The equipment has been installed in our newly built workshops and they will go a long way in enhancing the quality of training in the School. In addition, a new building at the main campus which is popularly known as Engineering Complex is substantially complete. The building is intended to house all the Engineering Departments in a very comfortable and serene environment which is conducive for effective learning. These facilities support our resolve to train and produce graduates with fine skills and deep knowledge of the engineering and architectural disciplines in which they are trained.
The School of Engineering and Architecture (SEA) is among the newest School in Meru University of Science and Technology. It was established in July 2016. This happened after the Department of Engineering which was in the School of Information and Technology and Engineering became a full fledged School. Currently the School has three departments namely;
- Department of Civil and Environmental Engineering
- Department of Electrical, Electronics and Communications Engineering
- Department of Mechanical and Mechatronics Engineering
Several academic programmes are currently run in the School. The Programmes include Degree, Diploma and Certificate programmes.
- Bachelor of Technology in Civil Engineering
- Bachelor of Technology in Mechanical Engineering
- Bachelor of Technology in Electrical and Electronics in Engineering
- Diploma in Civil Engineering
- Diploma in Electrical and Electronics Engineering
- Diploma in Mechanical Engineering
- Certificate in Electrical Installation
- Certificate in Motor Vehicle Technology
Our vision is to be a leading centre of excellence in engineering and architecture. In this regard we focus on furnishing our students with the finest instruction and strong foundations in engineering and architecture. Our core values which are integrity, commitment, academic and research excellence, professionalism, innovation, teamwork, equity and social justice and customer responsiveness are our guiding pillars which the School fraternity strongly believes in. Recently the School has received from the Government training equipment which are very modern. The equipment have been installed in our newly built workshops and they will go a long way in enhancing the quality of training in the School. In addition a new building at the main campus which is popularly known as Engineering Complex is substantially complete. The building is intended to house all the engineering departments in a very comfortable serene and attractive environment which is conducive for effective learning. These facilities are aimed at supporting our resolve to train and produce graduates with fine skills and deep knowledge of the engineering and architectural disciplines in which they are trained.
The Mechanical Engineering Department has existed since the inception of the Meru College of Technology in 1984 later Meru University College of Science and Technology and finally Meru University of Science and Technology that was given Charter to operate as a full-fledged public university in 2013.Mechanical Engineering Department
The department initially offered craft and diploma courses in automotive engineering examined by the Kenya National Examinations Council (KNEC). The department, part of the recently established School of Engineering and Architecture (SEA) currently offers a Bachelor of Technology degree in Mechanical Engineering, diploma in Mechatronic Engineering and certificate in motor vehicle technology.
Plans are under way to offer a Bachelor of Engineering degree in Mechanical and Mechatronic Engineering and later Petroleum Engineering, Chemical and Processing Engineering as well as Mining and Mineral Processing Engineering in order to address the current and future national labour needs and also towards attainment of the objectives of Kenya Vision 2030 and beyond.
The department is equipped with the state of the art training facilities that includes laboratories and workshops with CNC (computer numerically controlled) machines as well computers with internet access for research and training. We look forward to fulfilling our mandate of equipping young Kenyans with the necessary skills to drive this country and humanity forward.
Electrical and Electronic Engineering Department
The Electrical and Electronics Engineering Department has existed since 2003 under the then Meru College of Technology, which later became the Meru University College of Science and Technology and eventually the Meru University of Science and Technology in 2013 after receiving a charter.
Since its inception, the department offered craft courses examined by the Kenya National Examinations Council (KNEC). In 2010, the department introduced Diploma and Certificate courses which it offered under the School of Information Technology and Engineering (SITE). In 2014, the department started offering degree courses in Engineering Technology under the Engineering department. In July 2016, the school of Engineering and Architecture (SEA) was formed, after the splitting of the initially one Engineering department into three departments (Civil, Electrical and Mechanical). The department of Electrical, Electronic and Communications Engineering currently operates under SEA.
There are plans to establish a bachelor of engineering degree course in Electrical, Electronic and Communications Engineering department to help diversify workforce to meet the demand for diversity in the rapidly growing industrial environment.
The department, through the support of the University,has acquired excellent equipment and training facilities that embrace modern technology to ensure learners are equipped with skills relevant to the latest technology. We feel sufficiently empowered to announce to Kenyans and the world in general that we are ready to equip them with knowledge to face tomorrow with courage.
Civil and Environmental Engineering Department
The Department started since the inception of the then Meru university college of Science and Technology in 2009 with the vision of training high qualified civil engineers whose talent ,skills, ability and knowledge meet the requirements and needs of the Nation and potential private employers. The Engineers are also expected to carry out research in order to bring new insight into the academia bases of Civil Engineering field.
The Meru University of Science and Technology Department of Civil and Environmental Engineering has a mission of planning ,design, and construction of buildings, bridges, tunnels, transportation facilities and other structures required for health, welfare ,safety, employment and pleasure of the society and for environmental control and use of natural resources.
The department of civil and Environmental Engineering of Meru University is committed to high standards in products and service delivery. In this regard, the department pledges to offer competitive and client-driven, academic programmes aimed at producing quality products and services to its customers. Guided by the University’s vision, mission and core values and collaboration with stake holders the department seeks to provide quality training, research and technological transfer in the field of Civil and Environmental Engineering through nurturing an intellectual culture that integrates theory with practice and innovation for sustainable national and global development.
