Pavement laboratory equipment Staffing Academic Staff The NUC guidelines on staff/student ratio of 1:15 for Engineering and Technology departments shall apply. However, there should be a minimum of six full-time equivalents of Staff in the department. There is need to have a reasonable number of Staff with doctoral degrees as well as sufficient industrial experience. With a minimum load of 15 Units per semester for students and a minimum of six full-time equivalent of staff in each programme, staff should have a maximum of 15 contact hours per week for lectures, tutorials, practical’s and supervision of projects. NUC requirement encourages all academic staff to have PhD degrees; hence appointment of academic staff is preferably to the Lecturer cadre. Only in exceptional cases are candidates with great promise appointed to Graduate Assistant and Assistant Lecturer positions for the purpose of being developed to the Lecturer cadre as registered PhD candidates. Academic Support Personnel Teaching Assistant/Demonstrators to help lecturers in the conduct of tutorials, practical’s and field work. This category of personnel is not expected to be regular staff as they are to be paid on the basis of approved hourly rate. Administrative Support Staff The services of the administrative support staff are indispensable in the proper administration of the departments and faculty offices. It is important to recruit very competent senior staff that are computer literate. Technical Support Personnel The services of technical support staff, which are indispensable in the proper running of laboratories and workshop/studios are required. It is important to recruit very competent senior technical staff to maintain teaching and research equipment. They are also to undergo regular training to keep them abreast of developments in equipment operation and maintenance. The minimum of academic staff to technical staff ratio of 5:1 should be maintained. Minimum Number of Staff Subject to the general standards specified by NUC; Student/Staff Ratio The minimum staff-to-student ratio should be 1:15 from 200 level to 500 level. Library University Library Library books, journals and other resource materials should be adequate in number and currency Electronic Library The University library should subscribe to some on-line databases relevant to structural engineering degree programme such as: ASTM standards, ASTM digital library, compendex, Google Scholar, ICE virtual library – Ebooks, and computer-aided Civil and Infrastructure Engineering. Journals subscription should include volumes such as: IEEE Transactions on Intelligent Transportation Systems, Automation in Construction, Building and Environment, Energy and Buildings, Transportation Research Part B, Methodological, Transportation Research Part E, Logistics and Transportation Review, Structural Safety, Journal of Hydrology, and Tunnelling and Underground Space Technology. Faculty/Departmental Library A faculty or departmental library should be available for the use of staff and students.
