Integrated project services

Services

From the structural system to electrical and mechanical infrastructure, in coordination with the architecture, down to construction details, we manage every engineering discipline within a single coordination model.

Integrated approach

We bring different engineering disciplines together with the architectural vision in a single project.

From early design to construction and tender documents, we keep decisions aligned—reducing time, cost and construction risk.

Through BIM-based coordination, multidisciplinary clash detection and buildable detailing, we treat each project not just as drawings but as a constructible system.

ELECTRICAL

Electrical Design Engineering

Safe, efficient and future-ready electrical infrastructure—integrated solutions from power distribution and lighting design to low-voltage systems and BIM coordination.

We design energy performance and user experience together

01

Electrical Design Engineering

System concept, load analysis and technical design tailored to building type, use scenario and energy demand.

02

Power and Low-Voltage Construction Drawings

Construction drawings for power distribution, earthing and lightning protection, data, CCTV and access control, fire detection and PA, and building management systems (BMS).

03

Generator, UPS and Uninterruptible Power Systems

Capacity calculations, single-line diagrams and redundant supply design for generators, UPS and transfer systems serving critical loads.

04

Outdoor, Façade and Landscape Lighting

Professional lighting schemes that balance visual comfort, safety, energy consumption and architectural identity.

05

Energy Efficiency and Load Management

Consumption analysis, efficient equipment selection, power-factor correction and phased campus-scale electrical infrastructure master planning.

06

Data Center Electrical Systems

Uninterruptible power distribution for data centers with UPS, generators and 2N / A-B supply architecture.

Our process

We manage every discipline within one decision chain.

From initial analysis to construction documents, the project team works to shared data and coordination standards—so the architectural idea, engineering principles and site requirements stay connected.

Analysis

Analysing brief, regulations and site data

The client brief, zoning and Turkish Building Earthquake Code requirements, geotechnical and existing-building data, budget and schedule are assessed together, so scope, disciplines and BIM goals are clear from day one.

Design

Parallel structural, electrical and mechanical design

Structural systems, power distribution and HVAC solutions are modelled in Autodesk Revit on a shared coordinate system, so architectural ideas advance together with engineering checks and late revisions are reduced.

Coordination

Revit, Navisworks and clash detection

Discipline models are federated in Navisworks, hard and clearance clashes are reported with views via Clash Detective and resolved in Revit, closing beam–duct and column–pipe conflicts before construction.

Delivery

Buildable project documentation

Construction drawings, details, structural calculation reports and quantity take-offs are produced from the clash-free model and checked so contractors can use them directly on site.
