Our approach
Design & feasibility studies
Construction studies & methods
Cost studies & value engineering
Engineering applied to infrastructure
Multi-package coordination & interfaces
GTA Group has an in-house engineering and design office able to support project owners, engineering firms, designers and general contractors from the earliest planning stages through to on-site delivery.
Our approach combines technical design, operational feasibility, cost estimating, working methods and optimisation of solutions in constrained environments.
Project Owners
Securing the project from the early stages

What sets us apart
GTA Group’s engineering and design office is far more than a document factory. It is an operational engineering tool, directly connected to worksite realities.
This close link between design and execution makes it possible to secure the proposed solutions, anticipate risks and reduce gaps between study, price and production. Every GTA subsidiary benefits from this common foundation — ensuring technical consistency and control of interfaces on the most complex projects.
Why choose GTA?
Why our engineering makes the difference
Design / delivery vision
A single technical point of contact from study to delivery — continuity and consistency guaranteed.
Fewer construction risks
Risks are identified and dealt with at the study stage — before they turn into extra costs on site.
Control of technical interfaces
Coordination of civil works, equipment, fire protection, electrical and coatings packages within an integrated framework.
High-performance alternatives
Ability to propose and cost alternative solutions better suited to the project’s real constraints.
Circular economy built in
Every study addresses the repair, refurbishment and service-life extension of equipment.
Zero disruption at recommissioning
Proven on site — engineering that anticipates defects and secures handover without major snags.
GTA Group architecture
One engineering and design office, shared by all our subsidiaries
GTA Group’s integrated engineering is a cross-functional resource — each subsidiary benefits from it within its own field of expertise.
