The challenge<\/h2>\n

For the bid submission in the construction industry, long lists of requirements are painstakingly compiled in text form with calculations for the required craftsmen’s, machinery and material services. This construction calculation is done by experienced professionals whose time is very valuable for the company.[\/vc_column_text][vc_empty_space height=”30″][vc_column_text]<\/p>\n

How we helped<\/h2>\n

Since many elementary requirements for a construction object are often repeated in the various tenders, the XITASO data science experts developed a solution to make this calculation process more efficient. Based on past tender calculations and with the help of Data Science<\/a> & Artificial Intelligence methods, BRZ 365 AI calculation<\/a>\u00a0saves calculators a lot of time with precise recommendations. This can now be used for complex requirements of the construction project.[\/vc_column_text][vc_empty_space height=”30″][vc_column_text]<\/p>\n

Calculation proposals on three levels<\/strong><\/h3>\n

With BRZ 365 AI calculation, calculators always have full control over which past projects are included in the dataset and which automation level is used when processing the so-called bill of quantities:[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=””][vc_column][vc_empty_space height=”50″][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=”” el_class=”three-column-icon-and-text”][vc_column][vc_row_inner row_type=”row” type=”grid” text_align=”left” css_animation=””][vc_column_inner width=”1\/3″][vc_column_text]<\/p>\n

1. Recommendations of individual focus positions<\/strong><\/p>\n

Construction calculators process item by item and have a series of proposals generated for each item. They always decide for themselves which proposals are accepted and which are not.<\/p>\n

[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_column_text]<\/p>\n

2. Classification of the bill of quantities<\/b><\/p>\n

The classification of individual items visualizes the respective contribution in relation to the total price. This allows cost calculators to focus on expensive items and let the AI calculate the low-cost items.<\/p>\n

[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_column_text]<\/p>\n

3. Fully automatic calculation of all positions<\/strong><\/p>\n

The bill of quantities, including surcharges, prices, article and equipment lists, is calculated partially or completely automatically. As a result, construction calculators benefit from maximum time savings.<\/p>\n

\u201cThanks to XITASO’s data science expertise, we were able to bring an innovation to the market with the AI calculation that gives BRZ a great competitive advantage and users* real added value.\u201d<\/h3>\n

The XITASO Data Quick Check<\/div>\n

Validation of the project vision in only 15 days<\/h2>\n

BRZ’s vision was based on the assumption that the required craftsman, equipment and material services are similar if the requirements are very similar in content. To test this hypothesis, requirement texts were compared using Natural Language Processing (NLP) and the respective prices were controlled. This ensured feasibility<\/strong> before resources were poured into an implementation project.<\/p>\n

The result of the XITASO data quick check<\/a>confirmed the initial hypothesis and showed that past requirements can indeed be used to calculate bid prices. This laid the foundation for further successful product development<\/strong>.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_empty_space height=”80px” el_class=”not-on-mobile”][vc_single_image image=”37741″ img_size=”full” css=”.vc_custom_1660301717409{padding-right: 20px !important;padding-left: 20px !important;}” qode_css_animation=””][vc_column_text]<\/p>\n

User Centered Design Process<\/div>\n

Optimal usability through user centered approach<\/h2>\n

To ensure that the final software solution meets the concrete needs of the construction calculators<\/strong>, the UI\/UX experts at XITASO focused on them from the very beginning. In addition to defining user groups and the persona “Edgar Effizient” as well as examining the user journey, click dummies were tested on real users. This enabled early feedback, on the basis of which the solution was continuously improved and expanded. Throughout the development process, this ensured that features and concepts were always implemented from the user perspective and that the usability and acceptance of the product on the market were ensured<\/strong>.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=””][vc_column][vc_empty_space height=”30″ el_class=”not-on-mobile”][vc_empty_space height=”50″][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” el_class=”two-column-with-heading-on-top” z_index=””][vc_column][vc_row_inner row_type=”row” type=”grid” text_align=”left” css_animation=””][vc_column_inner][vc_column_text css=””]<\/p>\n
