Dragica (Vranić) Doršner grew up in an environment where many people worked in construction, including her father Franjo Vranić who, as a manager in Sarajevo's ŽGP, supervised and organized construction works, especially traffic infrastructure. For example during the construction of the first ski lift on Jahorina in 1954, he led the works on the construction of the starting and exiting stations. During her schooling, she often brought her father lunch to the construction site. While staying in the workroom, she looked at the spread plans, the way of drawing and dimensioning, technical presentation and reading the project of the building in the making. This got her interested and she decided to enroll in architecture. She spent the summer vacation from the time she passed her high school graduation to enrolling in the Faculty of Architecture practicing free drawing. It was back in 1961.
After graduating from the Faculty of Architecture in 1968, due to the shortage of graduate architects, she was immediately hired to spend an internship in a small office Project Studio, getting to know the technology of designing, processing and completing project documentation in accordance with legal regulations and investor requirements. She completed the second part of her internship in a smaller construction-craft company. After that, she got a job in the project bureau Stambeno predzuje Sarajevo (later called Sarajevostan), where she designed high-rise buildings as an associate designer, and as an independent designer with a professional exam in the field of design in 1973. Later, until the end of her working life, she mainly managed the preparation, organization and supervision of the execution of the so-called targeted housing construction in the city of Sarajevo.
"Sarajevostan" dealt exclusively with the design and supervision of the construction of residential buildings in the city. Given that the then socialist five-year planned housing construction amounted to approx. 8,800 apartments with shelters and schools and accompanying infrastructure, the city expanded intensively territorially as well. The new settlements of Grbavica I and Grbavica II, Hrasno I and Hrasno II were built, followed by the construction of Alipašino polje, Vojničko polje and Mojmil - until the construction of the Dobrinja settlement.
