The Nursing Faculty building is one of the buildings that fulfill the administrative eligibility in Andalas University, Padang - Indonesia, which was designed by a building design consultant based on the Indonesian standard code. During the building construction, the concrete quality was found to not to be in accordance with the designed concrete quality and construction was terminated by the owner. A structural evaluation of the building is carried out based on the Indonesia seismic code SNI 2847:2012. The results show that the building is not strong enough to withstand the combination of the loads acting on the structure, especially an earthquake load. Two methods were proposed to retrofit the building; by increasing the dimensions of the cross-section and add reinforcement to the structural elements (jacketing) and by adding some structural wall at the site of the plan with the aim to rigidify the building (shear wall). It is found that the two retrofitting methods are effective in reducing the internal forces and displacement on the building structures and the building is capable of resisting the working loads. Comparing the two retrofitting methods, the concrete jacketing column is more cost-effective than the shear wall method.
