Summary of training on Structural and Seismic Engineering 2016 The first year of the Structural and Seismic Engineering Training explored various construction techniques in RC structures, steel frame structures and timber structures. Through observation and direct feedback from participants, it became evident that the municipal engineers have sufficient technical knowledge and background in construction methods and design. It was identified that the biggest challenge was to narrow the capacity/knowledge gap between constituents among all stake- holders, especially the house owners, contractors and construction laborers. Furthermore, city engineers had limitations on spending enough time visiting construction sites to ensure the quality of construction and compliance to the Building Code. Based on this result, the second year trainings focused on the inspection process and making improvements to the system to ensure effective quality control of construction. 2 II.

This was implemented with the goal to speed up the building permit application system by digitalizing documents and allowing applications to be processed online. E-BPS enables municipalities to manage a building permit system by integrating the NBC and municipal BBL.
