Since ground level
An office founded by two civil engineers in Ankara, now a 46-person engineering and project management team.

Numbers at the desk, responsibility on site
We started in 2004 as two civil engineers with the structural design of a single school. It still stands and we visit it once a year.
Today we are 46: 31 engineers, 6 technicians, a BIM and reporting team. More than 140 buildings in six provinces, 1.2 million m² in total. The team that calculates is the team that signs on site.
One promise to every client: a report every week, same time, same format. Surprises belong in the report, not on site.

From the client’s logbook
Annex block
The hospital never closed for a day. The weekly report told us what was happening on site without a single extra meeting.
Nilüfer Park Residences
They checked every progress payment against quantities; for the first time we knew what we were paying for.
Gebze plant
They followed the crane runway details from shop drawing to erection. Not a single bolt hole was reamed on site.
