building engineering - общественное жилищное строительство, строительство гражданских зданий и сооружений building engineer - инженер-строитель

The study program for building engineering in universities is most often named ПГС - Промышленное и Гражданское Строительство How native speakers would really say "Building engineering" depends on the context. A good generic translation would be "Инженерное строительство".

I expect that this is проектирование зданий. The carreer is проектировщик.
