#Construction takeoff software for siding full size#

Total number of full size (1.5x1m high) panels = 2 units x 10 = 20 No. The wall height requires: 2,500/1,000 = 2.5 units along the vertical axis, The wall length requires: 15,000/1,500 = 10 units along the horizontal axis. The wall elevation is 15,000 x 2,500mm high. If you don’t have wall elevation drawings, you can calculate the number of fractional units as follows: On site, the contractor will cut the full-sized modular panels into the required size using a machine. The wall is 2,500mm high, so you will need 10 fractional units of size 1500 x 500mm high, in addition to the full-size panels (1500 x 1000mm high) which are (10×2) = 20 in number. In this case, a 2D or 3D drawing can visually show you the number and size of fractional units required:Ĭall Centre_Precast Concrete Modular Unit Panels the fractional units that a panel can be broken down into for completing the edges and ends of walls where a full panel doesn’t fit. You can also calculate the number of half or quarter units required i.e. Number of precast concrete units required = Wall area/Panel area = 25 units How many modular units (panels) do you need for this wall? The size of precast concrete modular units/panels is 1500 x 1000mm high, The side wall elevation of a call centre is 15,000 x 2,500mm high,

Upload your digital drawing into the software and it will automatically calculate quantities (areas, volumes, numerical and linear dimensions) using its geometric algorithm. This can be done manually or automatically if you have the client’s digital blueprints in 2D or 3D format. In this case, the contractor/estimator has to use estimating software that can take in measurements from the model. Some clients will require a total architectural overhaul or conceptual design that is done from scratch. The quantities will remain the same unless the model is adjusted or customized. Quantity Takeoff for Custom Prefabricated Building DesignsĪs explained in the beginning, quantity takeoff for standard house models does not involve changing quantities. Modular building is quickly becoming a modern method of construction, not only for residential buildings, but for commercial and industrial buildings as well.īuy a Newly-Built Home in your State - Price Range $250,000 to $50,000,000 In order to reduce construction time and save money in the process, the client has to employ modular building methods using large prefabricated panels or units.

Bricks are small building units compared to precast concrete modular units, and as a result, the bricklayer will spend a lot of time building the walls. Wet cement mortar joints are used to bind bricks together, and once again, you have to wait for the mortar joints to dry before proceeding to the next stage. In wet building methods, concrete is mixed, prepared and cast on site, so you have to wait for the concrete to dry before proceeding. The assembly of the building blocks can be finished within a day, so you can see why this method is better than the traditional wet building method which can take up to 12 months depending on the size and scope of the project. The building units are ready-made factory units that are ready for transportation to the site where the construction team will quickly assemble them to form a complete house or dwelling. The advantage of precast concrete or any type of modular building and prefabricated construction is that it’s a dry method of building. Contingencies or provisional sums for unforeseen work are usually not present in modular building or any kind of project employing 100% prefabricated methods. If the project is taxable (according to laws in your country), tax must added to the contract sum. For each item in the bills of quantities, the software must automatically add an allowance for labour, profit margin, overhead expenses and equipment etc.

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. They already know the number of modular units / panels needed to complete a specific standard model in their portfolio. 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. A Box-shaped Precast Concrete Wine Press designed by Architect Felix Burkhard in Mühlhofen, GermanyĮstimating and taking off quantities for precast concrete, modular or prefabricated building is a much easier task than quantification of wet construction methods.
