Approach

We begin with the physical and historical value of a place. We protect it through design, measured survey, restoration and archaeology. Digital systems keep that knowledge alive.

Istanbul Disaster Information System

Started before the 1999 Marmara earthquake, the system was revised around needs revealed during the disaster. The İTÜ KOSGEB-supported process also marked Akropol's move to the İTÜ Ayazağa Campus.

Core practices

What does Akropol do?

Akropol surveys sites and buildings, documents architectural and archaeological value, and produces conservation and design projects. It then connects this knowledge to GIS, BIM, digital-twin and structural-monitoring systems for decisions, delivery and long-term management.

01

Architectural conservation, restoration and implementation

Connects measured survey, restitution, restoration and engineering projects with site implementation and construction management.

02

Geodesy, surveying and mapping engineering

Measures land, structures, subsurface and coastal areas to project accuracy and produces reliable engineering data.

03

Digital twins and 3D spatial systems

Combines building, facility and project data on a measurable 3D model and turns space into a living information system.

04

GIS and remote sensing technologies

Combines spatial data for inventory, querying, analysis, remote sensing and decision support.

05

Scientific archaeological studies

Brings scientific excavation, archaeological documentation, art-historical research, artefact inventory and emergency conservation into one record chain.

06

Photogrammetry and laser scanning

Records buildings and sites with terrestrial, aerial and mobile methods to produce point clouds, orthophotos, measured surveys and 3D documents.

07

Urban transformation, planning and urban design

Carries regeneration areas from the building scale to neighbourhood and city scale through inventory, planning, design and implementation decisions.

08

Structural health monitoring and IoT

Tracks sensor, geodetic and field data over time and turns structural change into readable indicators, alerts and reports.
