Complex & 3D Take off

Costplan is able to provide complete quantity takeoffs from planning & concept sketches to tender & construction level designs. With our 3d takeoff software we are able to quickly and accurately takeoff even the most complex of jobs and generate 3D models & cut/fill grid reports. Our 2D software is not only fast and accurate but also able to produce simple and clear quantity takeoff plans so there is no confusion as to the extent of scope that has been taken off. We not only pride ourselves on the accuracy and speed but also our ability to cater each quantity takeoff to the level and presentation required by the client.

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, along with Planswift and ProContractor. Our key attribute is our ability to provide accurate and robust estimates in very limited time-frames.

Monte Carlo Analysis

Some projects require the statistical modelling of inherent and contingent risk, particular those funded by state and federal governments. Costplan has broad experience in providing Monte Carlo Analysis to produce P50/90 estimates. We utilise Palisades suite of risk management software to model this combined with a great deal of project risk knowledge.
