Cost estimation in full confidence

From Excel to Kabandy

Les Entreprises Louis De Waele is one of the leading general contractors in Belgium specialized in construction, renovation and restoration of buildings and civil infrastructures. The company belongs to Rabot Dutilleul (700M+ revenues in 2020), a French Group driven by innovation and sustainability.


In design and build projects, Les Entreprises Louis De Waele works in partnership with architects to apply to public and private calls for tenders. The cost estimating was traditionally based on quantities extracted from PDF drawings. This complex process required an extensive experience to achieve accurate results. Every inaccuracy could impact the profitability by several tens of thousands of euros. 

Lower the risk and save time

Over the last years, Les Entreprises Louis De Waele has received an increasing number of digital building models from the design team. The company made the decision to invest in digital solutions to get the most of them. The company now works with Kabandy and is able to visualize quantities directly on the model and in their report. They also developed their own rules and templates to automate cost estimating and connect their accounting Software. The company achieves more secured margins and reduces surprises in project accounts.

“Kabandy brings us more confidence in our cost estimating. The return on investment math is simple – even a tiny fraction of savings on one estimate would pay for the platform.”
