What is the key to success in construction projects?

For more than two decades IGG has been a respected name in the world of building economics in the Netherlands and beyond. Our consultants are familiar with all facets of the construction industry and provide cost estimates for your project to whatever levels of detail you require.

The benefits of integral construction costs

Current technology, clever programmes and in-house accurate databases has moved cost control beyond just being numbers and calculations. More than two decades of IGG being rather good has enabled us to move into a dynamic world of building economics where our integrated approach coupled with experience enables us to offer our clients an exceptional service. At IGG we create a team for each client’s project and in a very proactive and detailed way guide the whole process beyond mere cost estimates to a clearly set out a range of options. This may sound almost unnecessary but by setting out options for time, budget and methodology improvements in areas not obvious may enhance the viability of the project.

We look not only at what is on the drawing, but we also ask the right questions. As a result of which you not only get a detailed breakdown of the cost of your project, but also a clear picture of further possibilities to improve the economics of your project.
