Von Canal&#8217;s approach is consistent: &#8220;Keep it simple&#8221;. Instead of modeling each component with complex, multi-layered geometries, the effort is deliberately concentrated on enriching the information:  <\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Single-shell modeling<\/strong>: Elements such as walls (e.g. drywall, masonry or concrete walls) are only created as <strong>single-shell components<\/strong> in the Allplan model. There is a deliberate decision not to model each individual layer (cladding, insulation, stud frame) geometrically. <\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Information enrichment by attribute<\/strong>: All specifications required for the subsequent tender and cost calculation are instead added to the single-shell geometry as attributes. <br>These include\n<ul class=\"wp-block-list\">\n<li>Materiality and building physics<\/li>\n\n\n\n<li>Fire resistance class<\/li>\n\n\n\n<li>Sound insulation class<\/li>\n\n\n\n<li>Information on additional design details, e.g. whether a <strong>sliding ceiling connection<\/strong> is required.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Assured quality through wizards<\/strong>: The key to consistency is the use of self-developed Allplan wizards, which are available to all employees and contain all relevant attributes already preset. This minimizes errors and creates the basis for a &#8220;cleanly constructed 3D model&#8221;, which is essential for BIM with Allplan and NOVA AVA. <\/li>\n<\/ul>\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image size-large has-custom-border wp-duotone-unset-3\" style=\"margin-top:0;margin-right:0;margin-bottom:0;margin-left:0\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-19-1024x576.png\" alt=\"\" class=\"has-border-color has-vivid-cyan-blue-border-color wp-image-11331\" style=\"border-width:17px;box-shadow:var(--wp--preset--shadow--deep)\" srcset=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-19-1024x576.png 1024w, https:\/\/nova-ava.de\/wp-content\/uploads\/image-19.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Predefined Allplan wizards for different wall types with their BIM attributes.

To make this data usable for DIN and VOB processes, the <strong>creation of filters in NOVA AVA<\/strong> is the most important parameter. The filters are used to assign the components step by step and precisely to the desired cost or BOQ items.  <\/p>\n\n<p class=\"wp-block-paragraph\">Using the example of drywall, the speakers explain the detailed, seven-stage filtering process that von Canal has opted for in NOVA AVA:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Base<\/strong>: All elements of the model are included in the filter.<\/li>\n\n\n\n<li><strong>Component type<\/strong>: Only walls are filtered out; all other elements are removed.<\/li>\n\n\n\n<li><strong>Rough exclusion<\/strong>: All exterior wall components and load-bearing walls are removed, as only interior walls are relevant for the drywall construction trade.<\/li>\n\n\n\n<li><strong>Trade<\/strong>: The system filters specifically for the trade &#8220;Drywall work&#8221;.<\/li>\n\n\n\n<li><strong>Construction type<\/strong>: Differentiation by supporting structure, e.g. filtering by metal stud frame (to exclude timber stud frame, if relevant).<\/li>\n\n\n\n<li><strong>Detail<\/strong>: Further differentiation, e.g. according to shaft walls or walls planked on both sides.<\/li>\n\n\n\n<li><strong>Dimension<\/strong>: The final filtering is carried out according to the wall thickness (e.g. 15 cm).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This filter chain is the central prerequisite for precise quantity takeoff. The <strong>filter palette in NOVA AVA<\/strong> offers the option of displaying the filtered components visually in the 3D model at any time, which allows for quick plausibility checks and visual control. <\/p>\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image size-large has-custom-border wp-duotone-unset-4\" style=\"margin-top:0;margin-right:0;margin-bottom:0;margin-left:0\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-20-1024x576.png\" alt=\"\" class=\"has-border-color has-vivid-cyan-blue-border-color wp-image-11335\" style=\"border-width:17px;box-shadow:var(--wp--preset--shadow--deep)\" srcset=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-20-1024x576.png 1024w, https:\/\/nova-ava.de\/wp-content\/uploads\/image-20.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">NOVA AVA is characterized by clarity &#8211; not least thanks to the interaction of the integrated BIM model viewer here with the display of wall types (left) and the corresponding filter setting (right).

Model-based cost calculation according to DIN 276. <\/p>\n\n<p class=\"wp-block-paragraph\">After importing the IFC structure, <strong>cost elements<\/strong> are created in NOVA AVA. These contain individual costs (e.g. price per cubic meter of concrete, square meter of formwork) and are assigned to a service area and the appropriate <strong>DIN cost group<\/strong>. Each cost element is linked to the corresponding component in the model using the previously defined filters.   The result is a model-based cost calculation that is structured according to DIN and provides the necessary level of detail for budget control and cost estimation in the early phases.  <\/p>\n\n<h2 class=\"wp-block-heading\">Secured quantity export and VOB special cases<\/h2>\n\n<p class=\"wp-block-paragraph\">In contrast to some other BIM workflows, von Canal relies on <strong>secure quantity export<\/strong> for the tender. The BOQ is not generated automatically, as the export from the model is not yet considered secure enough for this. <\/p>\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image size-large has-custom-border wp-duotone-unset-5\" style=\"margin-top:0;margin-right:0;margin-bottom:0;margin-left:0\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-21-1024x576.png\" alt=\"\" class=\"has-border-color has-vivid-cyan-blue-border-color wp-image-11338\" style=\"border-width:17px;box-shadow:var(--wp--preset--shadow--deep)\" srcset=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-21-1024x576.png 1024w, https:\/\/nova-ava.de\/wp-content\/uploads\/image-21.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The sliding ceiling connection allowance is calculated from the wall length, which is read from the model.

This identifies all openings in drywalls that are smaller than 2.5 m\u00b2 and adds these quantities to the net quantities. In this way, VOB-compliant quantities are generated despite the &#8220;keep it simple&#8221; modeling.  <\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Non-modeled allowances<\/strong>: Structurally complex but geometrically simple elements such as the allowance for a <strong>sliding ceiling connection<\/strong> (which would usually require a separate, complex component) are also mapped using filters. An attribute filter identifies walls with the attribute &#8220;floating ceiling connection&#8221;, reads the <strong>length of the wall<\/strong> from the geometry data and uses this to generate the corresponding allowance item in the BOQ. <\/li>\n<\/ul>\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 class=\"wp-block-heading\">Conclusion: speed and control as decisive competitive advantages<\/h2>\n\n<p class=\"wp-block-paragraph\">The consistent use of <strong>BIM with Allplan and NOVA AVA<\/strong> has led to a highly parametric process chain for von Canal Architekten, the benefits of which go far beyond mere quantity takeoff:<\/p>\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image size-large has-custom-border wp-duotone-unset-6\" style=\"margin-top:0;margin-right:0;margin-bottom:0;margin-left:0\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-22-1024x576.png\" alt=\"\" class=\"has-border-color has-vivid-cyan-blue-border-color wp-image-11340\" style=\"border-width:17px;box-shadow:var(--wp--preset--shadow--deep)\" srcset=\"https:\/\/nova-ava.de\/wp-content\/uploads\/image-22-1024x576.png 1024w, https:\/\/nova-ava.de\/wp-content\/uploads\/image-22.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The most important advantages of the demonstrated BIM workflow with Allplan and NOVA AVA.
