Our Values

Above all we believe in professional delivery.

We achieve it by focusing on dialogue and collaboration with our clients. This creates trust and builds effective working partnerships. Supported by the breadth and depth of our professional capabilities, we provide unrivalled quality of service.

We are driven by innovation.

In our continuously changing and developing industry we are constantly searching for and implementing innovative approaches in order to meet our client''s aspirations and improve all aspects of their businesses.

Our long-term focus is on sustainability.

We believe that sustainable development delivers a better future. Our intelligent design and whole life value approach contribute to sustainable development as well as cost-effective performance of buildings and infrastructures.

Our Approach

Project success and client satisfaction is what underlies GI’s business approach.

We are ISO 9001 certified. This means that we deliver constant performance and that our clients receive services that meet their requirements. It also means that we remain focused on our continuous improvement.

Our project management includes the functions of planning, monitoring and control. At GI, we pay special attention to the preparation, discussion and elaboration of a project plan. Our project plan, from the inception to the detailed plan of daily activities, is always structured in a clear and layered way. We ensure that all project development phases are defined, risks allocated and cash flows arranged in line with the client's demands and constraints.

In complex, technically and commercially demanding projects various interest groups tend to emerge, often with mutually opposed positions and demands. In the process of project management, we create a system aimed at harmonising divergent positions of different stakeholders and identifying an acceptable implementation model that will successfully address the critical components determining each project: time, money and quality. We see this as a crucial task of project management.

Our History

GI activities started with the foundation of Investinženjering d.o.o. in 1989. – a private company offering engineering services in the construction sector. In 1992 Studio A d.o.o. was established by Investinženjering and a year later Tower 151 Architects – Zagreb d.o.o., bringing architects and urban developers to the group.

After a very successful cooperation with Deutsche Gesellschaft für Technische Zusammenarbeit GmbH (GTZ) in designing, managing and supervising the construction of 50.000m2 dwelling settlements for war refugees in early 1990''s, GI has managed to establish cooperation with many foreign clients and consultants with whom it has closely cooperated on projects in Croatia and in the region.

As the first major recognition of the excellence of our services, in 1995 Importanne Centre - the first shopping centre in Zagreb, was erected under the project and construction management by GI.

In response to the industry growth supported by the large infrastructure projects in Croatia, in the first decade of the new millennium the GI companies continuously expanded to new areas of professional expertise.

Since 2002 GI has been supervising construction of several sections of Zagreb – Split – Dubrovnik Highway.

In 2006 we received the first award in the international competition for the preliminary design of the largest telescope in the world - ELT Telescope Project on the Canary Islands (partnership with The Lund University).

In 2007 Hypo Alpe-Adria Center, the largest high-rise construction project in Croatia with the total area of 86.000m2, was completed under the project and construction management and supervision by GI.

In 2008 we opened office in Zadar, which gave us a strong regional foothold and an ability to better serve our clients in Dalmatia. Our successful development and growth enabled us to invest in a 14.700m2 property development project, which was completed in 2010. Today Tuškanova/Banjavčićeva complex also hosts our new offices.

Over the period of more than 20 years working as engineering consultants, we have always been striving for excellence. We have achieved it through continuous investments in training of our people and in building close relationships with the best international and local partners.
