In 2004, the Commission for the Preservation of National Monuments declared the "Architectural Complex of Husejnija (Husein-kapetan Gradaščević) Mosque in Gradačac" a national monument of Bosnia and Herzegovina. The mosque belongs to the type of central domed mosque with a portico covered by three small domes. In September/October 2023, cracks were observed on six arches, the capitals of two columns, and the base of one column in the portico of the mosque. Geotechnical investigative works included the creation of three excavations and two boreholes with continuous Standard Penetration Tests (SPT). The excavations reveal layers below the ground level, consisting of a well-bound sandy artificial fill from the ground surface to a depth of 1.35 meters, a layer of poorly bound artificial stony material from 1.35 to 2.45 meters, and a layer of natural clay at greater depths. It is assumed that over time, due to water seepage from the hillside and rainfall runoff from the mosque, there has been a change in the physical-mechanical properties of the foundation soil and partial settling of the portico structure. In addition to the existing channel on two sides of the mosque, a drainage ring around the building and a drainage curtain on the uphill slope have been designed. Also, underpinning of the portico foundations in alternating segments has been designed to strengthen the stone masonry layer and prevent further settling and development of cracks in the portico elements. After the works are completed, a 12-month monitoring period is planned, followed by an analysis and repair of the cracks.

Wind Farm Podveležje is located on the plateau Podveležje, about 10 km east of the city of Mostar, in the center of the Herzegovina-Neretva Canton. The Wind Farm consists of 15 wind turbines, each with a power of 3.2 MW, making a total capacity of 48 MW. The geological structure of the surrounding area on the Podveležje plateau is very complex due to its intricate tectonic complex, ranging from layered to thinly layered Upper Cretaceous limestone with Turonian-aged radiolites as the bedrock. Cracks are often highly prominent, filled with rock weathering products, terra rosa and clay material. During geological and geotechnical investigations at foundation locations, caverns were identified in certain places. The program of additional works (destructive boreholes and TV logging) was carried out to delineate the cavern locations on WT-3, WT-4, WT-8, WT-12, WT-15, and WT-16 plateaus. The aim of the paper is to describe the cavern rehabilitation at locations of wind turbine foundation including substrate preparation, filling procedures, mixture composition, and performing destructive boreholes to verify rock mass compactness.

The paper presents a diagnosis of the condition of the stadium FK Velež “Rođeni” in Mostar, which was built in period 2006-2008 and represents an important facility for the citizens of Mostar. The steps in diagnosing the condition of an existing structure are explained, including a collection of existing documentation, an inspection of the structure, test and calculations, and assessment and decision on further action. Drawings of the stadium were given, visual inspection of the stadium was performed and calculations of the current and future layout of the structure. The calculations were performed in software Tower 8 and with respect to European norms EN0, EN1, EN2, EN3 and EN8. A visual inspection revealed a large number of damages to the stadium, which were classified into specific groups. The mechanisms of destruction and classification were performed using EN 1504.
