Cost Estimating

Our core business is the provision of cost estimates to all aspects of industry, from contractor to client. Dependant on the projects current phase these can range from budget and benchmarked costs (QS style) all the way through to detailed first principle calculated estimates. We are one of the country’s oldest users of the excellent Pronamics “Expert Estimator” software. Our key attribute is our ability to provide accurate and robust estimates in very limited time-frames.

Monte Carlo Analysis
