Abdullah graduated from Delft University of Technology with a specialisation in Design & Construction Management. During and after his studies he worked at a consultancy firm and a project developer.

Abdullah has been working at IGG since 2016 as a construction cost consultant and is involved in the preparation and testing of construction cost estimates, the execution of feasibility studies and consulting the client regarding construction costs for complex construction projects. The design and realisation process is complex, full of risks and requires good management with insight. As a cost consultant, Abdullah finds it particularly interesting to steer these complex projects in an early phase with creative and integrated solutions that lead to better results within the project frameworks of time, money and quality.

Abdullah is very involved, thinks proactively and looks for integrated solutions to realize complex projects. For IGG, Abdullah has, among other thins, been involved with the renovation and expansion of Paleis Het Loo in Apeldoorn, Hanzehogeschool in Groningen and the University of Groningen. He has also worked on various residential and non-residential projects.

Ahmed completed his Master's in Building Technology at Delft University of Technology in 2018 in the field of load-bearing construction, building construction and building physics. For his graduation project, he focused on the development of a sustainable, innovative, transparent facade for non-residential construction. After his studies he worked at a consulting engineering firm.

Ahmed has been working at IGG since 2019 as a construction cost consultant, where his responsibilities are focused on drafting feasibility studies, estimates and budgets based on analysing complex construction projects during various design phases. Due to the increasing complexity of construction projects, adequate construction cost advice is fundamental to guarantee financial feasibility. As a result, Ahmed uses its building technology knowledge and expertise to provide clients with an integrated perspective on construction costs.

Ahmed is very driven to bring complex building projects to positive results, with potential risks being identified in time. This includes a proactive approach, a healthy relationship between quality and construction budget, customer focus and involvement in various residential and non-residential projects. These are also his driving forces.

Rob studied architecture at the HTS in The Hague and from that moment on has been interested in the possibilities of computerisation and digitisation. He uses his analytical ability to apply calculation models to problems. If there are none or unclear frameworks for an issue, he will start there. He does not hesitate to point out unrealistic budgets to the client and he identifies risks at an early stage, so that there is sufficient time to anticipate them. Identifying bottlenecks and coming up with solutions are inextricably linked.

He has a background of more than 15 years as a construction cost consultant at a medium-sized architectural firm and a construction cost consultancy, and has gained a lot of experience with school construction, care institutions and large housing projects. Rob has been working at IGG since 2013. He is particularly interested in lifecycle costs, as these can be strongly influenced during the initiation and design phase. After all, the essential choices are made here in terms of MEP, materials, components, etc.

Sustainability is therefore logically an extension of the areas of interest, because sustainable use of materials can help to limit the lifecycle costs.

Steven is an all-round project leader who has supervised construction and real estate related projects for both clients and contractors. In recent years he has specialised in tenders, where he has sat on both sides of the table.

In the role of tender manager or consultant, he has since been involved in more than 80 tenders. His Architectural (HTS) and Public Administration (University) background comes in handy here.

For Steven, a tender is never a goal in itself, but always a means to make projects a success. After all, basically a tender is nothing more than asking the market a question and ensuring that a good answer is given. Preferably several, because then there is something to choose from. By not only organising the tendering procedure, but also formulating the request correctly, the chance of a correct answer considerably increases. A tender forms the basis for future cooperation.

Steven has been working at IGG since 2016 and is always closely involved in his projects, where the interests of the client always come first.
