Energy & Special Engineering Projects

Preparation of terrain data, cadastral records and survey infrastructure for renewable energy, expropriation and special engineering projects.

Energy investments deal with land long before they deal with structures. The panel layout of a solar site is built on slope and aspect data; the route of a transmission line is shaped by the ownership status of every parcel it crosses. Substantial land and cadastral work is therefore needed before the project is even drawn.

Site suitability is not limited to topography. Parcel boundaries, ownership structure, existing easements and access roads all bear directly on the cost of the investment. Establishing this data before the project reduces the surprises that surface later.

Expropriation and easement work is carried out within the framework of Expropriation Law No. 2942. The affected area has to be calculated and a technical file prepared for each parcel — on linear projects that can mean hundreds of parcels.

How We Work

Process

  1. Preliminary site analysis

    An initial assessment is made from existing mapping, satellite imagery and cadastral data.

  2. Land and cadastral survey

    The site is surveyed topographically and parcel boundaries are matched against cadastral records.

  3. Data production

    Slope, aspect and surface models are derived to support panel layout or route optimisation.

  4. Expropriation and easement calculation

    Affected parcels are identified, areas are calculated and technical files are prepared.

  5. Setting-out and control

    The approved design is set out on site and position checks are carried out during construction.

FAQ

Common questions

What data does a solar site require?
At minimum a topographic map, a digital terrain model and the slope and aspect analyses derived from it. Height data is critical so that panel rows can be laid out without shading one another.
What is an expropriation plan?
A technical plan, prepared with area calculations, showing how much of each parcel along a project route will be expropriated. It forms the basis for calculating compensation.
What is the difference between easement and expropriation?
In expropriation ownership of the property changes hands; under an easement ownership stays with the owner but a defined right of use is established over the property. Power transmission lines mostly use easements.
How does the process work with hundreds of parcels?
Parcels are matched against cadastral data and processed in bulk; the affected area is calculated for each and a separate file is produced. On linear projects of this kind, most of the work is data management rather than fieldwork.

Service Areas

Districts we serve in Istanbul

Energy projects mostly run on large sites outside the city, so in this field we work across Türkiye. In Istanbul we carry out preliminary site analysis and topographic mapping on the larger plots of Silivri, Başakşehir, Beykoz and Sarıyer, and provide technical support for expropriation and easement work on power lines in Kadıköy, Üsküdar, Ataşehir, Maltepe, Kartal, Pendik, Ümraniye, Bakırköy, Beşiktaş and Beylikdüzü.
