10 Best Estimating Takeoff Software for Precast Concrete, Modular Building and Prefabricated Metal / Timber Construction
Estimating and taking off quantities for precast concrete, modular or prefabricated building is a much easier task than quantification of wet construction methods. Most of the time, contractors specializing in prefabricated building have standard house designs and models which can easily be replicated on site anywhere where the site conditions are not extra-ordinary. They already know the number of modular units / panels needed to complete a specific standard model in their portfolio. The estimating software for this kind of work can generate pre-existing quantities (quantities for standard models never change) and it will also price each model using rates from the modular unit manufacturer or factory. For each item in the bills of quantities, the software must automatically add an allowance for labour, profit margin, overhead expenses and equipment etc. If the project is taxable (according to laws in your country), tax must added to the contract sum. Contingencies or provisional sums for unforeseen work are usually not present in modular building or any kind of project employing 100% prefabricated methods.
