The Challenge
The Church of St. Martin, a late Gothic-Renaissance style building in Croatia, was left in ruins after the great earthquake of 1880. The church, which is a protected cultural monument, suffered numerous structural cracks and partial or complete demolition of its vaults. Over time, the church was forgotten and never repaired. The challenge was to restore this historic building and revitalize the entire area. The missing elements of the building, such as the tower roof and the nave, needed to be restored. The masonry, cracks, and foundations in the bell tower needed structural repair. The architects also planned to add a new, contemporary dome and a spiral staircase or lift for access to the tower. The main nave’s function was to be restored by adding cubes made from contemporary materials and architectural forms.
About The Customer
Foretić Architects, the firm handling the restoration, was founded in 1995 and has 25 years of successful business tradition. The firm is small but boasts a team of designers, engineers, associates, and coworkers with more than 40 years of combined experience on significant construction and design projects. The mixed team of older and young engineers allows them to leverage their vast experience with a fresh, modern project approach. Some of their experts have a special 'Cultural buildings work certificate' from the Ministry of Culture, Republic of Croatia, allowing them to design and work on cultural and heritage building projects. They have been using Archicad since 1995 and use BIM technology in their everyday work.
The Solution
The architects decided to use Building Information Modeling (BIM) software, Archicad, and BIMx app to tackle these challenges. The software was used to develop an 'informational virtual walk' to present the old and renovated look of the church, along with basic facts about the structure, its location, and archaeological findings. The BIMx app was used to combine old and new 3D models of the church, the virtual walk, and an exploration of the 3D model with a thematic booklet. The BIMx Desktop Viewer integrated the background and the 'making of' renovation animation using a free publish/print screen movie program. Photogrammetry was used in Archicad to relay the real surface, which was more useful than point clouds. Archicad was used to model all the architectural elements like ornaments, baroque tower roof, cornices, etc.

Intelligent Building Automation System and Energy Saving Solution
One of the most difficult problems facing the world is conserving energy in buildings. However, it is not easy to have a cost-effective solution to reduce energy usage in a building. One solution for saving energy is to implement an intelligent building automation system (BAS) which can be controlled according to its schedule. In Indonesia a large university with a five floor building and 22 classrooms wanted to save the amount of energy being used.
