Construction cost consulting

In every single accommodation and planning project, the cost aspect is hugely important. Regardless of your market, i.e. commercial property or property with a social function, reliable costing is paramount right from the preliminary design stage.

Cost control is, without doubt, one of the critical success factors for a project during the overall development and construction process. BOAG has in-house quantity surveyors who can assist you from the start of the initiative.

Analyses and estimates

You can safely leave your feasibility analyses and cost estimation to us. Thanks to our knowledge and experience, we have the latest information needed to be able to calculate your general construction site costs, estimate the costs of separate elements, and determine the time needed for your construction project. We can also engage with investors, either with you or on your behalf. We identify bottlenecks at an early stage and will explain the financial consequences of the various options to you. BOAG’s integrated approach, which links construction cost aspects to technical content, is our strength.

Keeping a grip on finances

As the client, you want your ‘end product’ completed on time, as per agreements with the various parties involved, on spec, and on budget. The quantity surveyor plays a key role throughout the development and implementation process. At each stage of the process, he or she will verify that the project still runs on budget. The project manager can subsequently manage the project accordingly. Our clear advice, explanations, and management reports will enable you to keep a grip on the process and be sure of your decisions.

Different forms of construction cost consulting

Construction cost consulting relates to all kinds of aspects of the development and construction process. Each analysis and estimate, as well as each piece of advice, is customised. The following lists some of the aspects of our construction cost consulting service.

Sustainable environment

There is an increasing focus on sustainability and circular economy, due to building running costs on the one hand – the more money can be recovered, the more attractive – and the preferences of end users on the other. What many organisations aspire to is a sustainability label such as BREEAM and WELL. In the education sector, the principles of the ‘Frisse Scholen’ initiative for healthy and energy-efficient school buildings are often taken as the starting point, while operators in the healthcare industry go by the Green Deal approach. BOAG’s ‘Green quantity surveyors’ are able to help you go over your options and provide advice. For certifications, BOAG has its own in-house BREEAM assessors. As a member of the Dutch Green Building Council, we are actively involved in moving the built environment towards sustainability.


Besides being a member of the Dutch Green Building Council, BOAG is also a member of the Netherlands Association of Quantity Surveyors (Nederlandse Vereniging van Bouw Kostendeskundigen (NVBK)) and of the Netherlands Association of Procurement Professionals (Nederlandse Vereniging van Inkopers (NEVI)). Our quantity surveyor is a registered cost manager (Register Kostenmanager (RKN)).
