However, on-site verification showed that the bottom edge of the cable tray remained constant along its entire length, with no elevation change.&nbsp;<br><br>In a traditional approach, this discrepancy would have been identified by comparing the Revit BIM model with the 3D scan. This method is time-consuming due to the large size of the model, causing slow performance in Revit. It also carries a risk of omissions, which is particularly critical in a Data Center model that includes many equipment items and cable routing systems.<br><br>Using Gamma AR and 3D scanning technology, a comprehensive scan of the building was first carried out to accurately capture the existing conditions. The BIM model&nbsp;was then overlaid onto the real environment using augmented reality, enabling rapid identification of discrepancies between the digital model and the as-built conditions on site. Once a&nbsp;discrepancy&nbsp;was detected, an issue was created directly within the application, documented with the relevant information, and shared with the appropriate team for review and resolution. Finally, the point cloud generated from the 3D scan was used as a reliable reference to determine the correct position of the affected elements and update the BIM model accordingly.<\/p>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-b9162e6 e-con e-atomic-element e-flexbox-base e-b9162e6-5f42c0d \" data-id=\"b9162e6\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"b9162e6\" data-e-type=\"e-flexbox\" data-id=\"b9162e6\">\n    \t\t\t<h4 data-interaction-id=\"51ffe96\" class=\"g-a333c7b BodyBold e-heading-base\" data-e-type=\"widget\" data-id=\"51ffe96\">Case 2: Verification of&nbsp;lighting&nbsp;in the office area&nbsp;<\/h4>\n\t\t<div class=\"elementor-element elementor-element-ccea9c3 e-con e-atomic-element e-flexbox-base e-ccea9c3-a88b51f \" data-id=\"ccea9c3\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"ccea9c3\" data-e-type=\"e-flexbox\" data-id=\"ccea9c3\">\n    <div class=\"elementor-element elementor-element-646e8cd e-con e-atomic-element e-flexbox-base e-646e8cd-f84eaae \" data-id=\"646e8cd\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"646e8cd\" data-e-type=\"e-flexbox\" data-id=\"646e8cd\">\n    \t\t\t<img loading=\"lazy\" decoding=\"async\" class=\"e-image-base \" data-interaction-id=\"e197d7a\" data-e-type=\"widget\" data-id=\"e197d7a\" id=\"38236\" src=\"https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4.webp\" width=\"1668\" height=\"2388\" srcset=\"https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4.webp 1668w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4-210x300.webp 210w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4-715x1024.webp 715w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4-768x1100.webp 768w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4-1073x1536.webp 1073w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap4-1431x2048.webp 1431w\" alt=\"Screenshot of the app on GAMMA AR\"\/>\t\t\t\t\t<p class=\"e-a808e23-3d3018a e-paragraph-base\" data-interaction-id=\"a808e23\" data-e-type=\"widget\" data-id=\"a808e23\">Lighting realised<\/p>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-4efe97d e-con e-atomic-element e-flexbox-base e-4efe97d-2b31813 \" data-id=\"4efe97d\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"4efe97d\" data-e-type=\"e-flexbox\" data-id=\"4efe97d\">\n    \t\t\t<img loading=\"lazy\" decoding=\"async\" class=\"e-image-base \" data-interaction-id=\"6243f4b\" data-e-type=\"widget\" data-id=\"6243f4b\" id=\"38224\" src=\"https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3.webp\" width=\"1668\" height=\"2388\" srcset=\"https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3.webp 1668w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3-210x300.webp 210w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3-715x1024.webp 715w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3-768x1100.webp 768w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3-1073x1536.webp 1073w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/cap3-1431x2048.webp 1431w\" alt=\"Screenshot of the app on GAMMA AR\"\/>\t\t\t\t\t<p class=\"e-a06cd22-7555532 e-paragraph-base\" data-interaction-id=\"a06cd22\" data-e-type=\"widget\" data-id=\"a06cd22\">Reality overlay model<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\t\t\t<p class=\"Body e-paragraph-base\" data-interaction-id=\"d359fff\" data-e-type=\"widget\" data-id=\"d359fff\">In the office area, a discrepancy was identified between the actual position of the lighting and their representation in the BIM model. This difference was caused by the false ceiling, whose actual height differed from the modeled one, resulting in a misalignment of the luminaires.&nbsp;<br><br>In a traditional approach, this discrepancy could have been identified by comparing the Revit BIM model with the point cloud model generated from the 3D scan. However, the use of scanning requires defining an acquisition resolution, which generates additional costs and may limit the level of detail obtained. At this resolution, certain elements, such as luminaires, may not be clearly identifiable in the point cloud. The false ceiling layout would also have had to be checked using the point cloud model. Finally, manual measurements would have been required before transmitting the information to the responsible trade for correction.&nbsp;<br><br>With GAMMA AR and 3D scanning, a site scan was first performed. Overlaying the model onto the site enabled rapid identification of discrepancies related to both the luminaires and the false ceiling. The information was then transmitted to the responsible trade for correction, while the 3D scan enabled the BIM model to be updated in accordance with actual site conditions.&nbsp;<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\t\t\t\n<hr class=\"e-6dac58f-279c245 e-divider-base\" data-interaction-id=\"6dac58f\"  data-e-type=\"widget\" data-id=\"6dac58f\" \/>\n\t\t\t\t\t<p class=\"Body e-paragraph-base\" data-interaction-id=\"2296eb8\" data-e-type=\"widget\" data-id=\"2296eb8\">These two cases clearly illustrate the tool\u2019s day-to-day contribution: identifying discrepancies on site, documenting them in just a few clicks, and directly transmitting them to the right stakeholders so they can be addressed without delay.<\/p>\n\t\t\t\t\t<h3 data-interaction-id=\"a7e56b2\" class=\"g-a333c7b H2-35 e-heading-base\" data-e-type=\"widget\" data-id=\"a7e56b2\">Results<\/h3>\n\t\t\t\t\t<p class=\"Body e-paragraph-base\" data-interaction-id=\"3cc4b34\" data-e-type=\"widget\" data-id=\"3cc4b34\">A total of 608 issues were created during the project. On-site discrepancy detection mobilized two full-time people over four days, supplemented by a third person present during the first three days. This phase represented a total of 11 person-days, corresponding to approximately 66 hours of effective work, or about 8 to 9 man-days based on a 7.5-hour working day. This corresponds to an average cycle time of 6 min 30 s per issue, as well as an average throughput of approximately 152 issues processed per day.&nbsp;<br><br>The updates to the BIM model were then carried out over a period of approximately three weeks by one full-time field engineer, a half-time BIM modeler, and an additional company resource brought in to provide support.&nbsp;<br><br>Without the use of GAMMA AR for the As-Built Documentation (DOE) of this Data Center, resource requirements would have been higher, particularly in terms of BIM modelers,&nbsp;to&nbsp;meet project deadlines. This would have resulted in increased costs as well as greater allocation of teams to this project, to the detriment of other ongoing operations.&nbsp;<br><br>With a constant workforce, the absence of this optimization would also have led to an increase in the total number of man-days required for the entire DOE phase due to longer processing times and increased rework.&nbsp;<br><br>This additional workload could have generated delays or slowdowns on other projects, as well as an increased risk of failing to detect certain non-conformities. Consequently, the overall project cost (CBS) would have been higher than in the current configuration.&nbsp;<br><br>The DOE has been delivered in full and accepted without comment. The 2 cm requirement could not be met, as it is impossible to certify a deviation of less than 5 cm.&nbsp;<br><br>For BIM modelers, the benefits were tangible: instead of navigating through the entire 3D model to locate issues themselves, they received directly in Revit documented, localized, and dimensioned issues, enabling them to address corrections in a targeted and efficient manner. The delivered model accurately reflects the installations completed on site, providing the client with a reliable and immediately usable digital model.&nbsp;<br><br>Building on this experience, Bouygues \u00c9nergies &amp; Services continues to deploy GAMMA AR on its upcoming projects. The objective is to capitalize on the benefits observed in terms of quality, productivity, and collaboration&nbsp;to&nbsp;continue improving performance on increasingly demanding projects.&nbsp;<\/p>\n\t\t<div class=\"elementor-element elementor-element-7de326b e-con e-atomic-element e-flexbox-base e-7de326b-0f2b8aa \" data-id=\"7de326b\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"7de326b\" data-e-type=\"e-flexbox\" data-id=\"7de326b\">\n    \t\t\t<p class=\"e-paragraph-base\" data-interaction-id=\"f674139\" data-e-type=\"widget\" data-id=\"f674139\">Learnings:\u202fDuring the project, Bouygues \u00c9nergies &amp; Services identified several best practices for future deployments:&nbsp;<br><br>\u2022&nbsp;provide an external battery pack for each iPad;&nbsp;<br>\u2022&nbsp;recharge tablets and external batteries simultaneously;&nbsp;<br>\u2022&nbsp;reload the required models onto the devices before going on site;&nbsp;<br>\u2022&nbsp;limit the display distance to optimize battery life;&nbsp;<br>\u2022&nbsp;raise awareness among site teams regarding the use and location of QR codes to prevent them from being moved.&nbsp;<\/p>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-5cf275c e-con e-atomic-element e-div-block-base e-5cf275c-167e266 \" data-id=\"5cf275c\" data-element_type=\"e-div-block\" data-e-type=\"e-div-block\" data-interaction-id=\"5cf275c\" data-e-type=\"e-div-block\" data-id=\"5cf275c\">\n    \t\t\t<img loading=\"lazy\" decoding=\"async\" class=\"e-image-base g-f3551c1 e-05186fd-98842d6\" data-interaction-id=\"05186fd\" data-e-type=\"widget\" data-id=\"05186fd\" id=\"38344\" src=\"https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/Saisie_de_CDC.webp\" width=\"2000\" height=\"1123\" srcset=\"https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/Saisie_de_CDC.webp 2000w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/Saisie_de_CDC-300x168.webp 300w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/Saisie_de_CDC-1024x575.webp 1024w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/Saisie_de_CDC-768x431.webp 768w, https:\/\/gamma-ar.com\/wp-content\/uploads\/2026\/07\/Saisie_de_CDC-1536x862.webp 1536w\" alt=\"Saisie de CDC\"\/>\t\t\n<\/div>\n\t\t\t<h2 data-interaction-id=\"ddbc018\" class=\"g-a333c7b H2-35 e-heading-base\" data-e-type=\"widget\" data-id=\"ddbc018\">Generic Results<\/h2>\n\t\t\t\t\t<p class=\"Body e-paragraph-base\" data-interaction-id=\"5a602a3\" data-e-type=\"widget\" data-id=\"5a602a3\">Furthermore, the absence of on-site augmented reality visualization would have limited the design office teams\u2019 understanding of actual site conditions. This would have increased the risk of designing or validating solutions that are difficult to implement on site, potentially impacting other projects and increasing the risk of rework due to analyses based solely on the digital model.&nbsp;<br><br>Bouygues \u00c9nergies &amp; Services aims to strengthen the integration of field constraints into the design process while remaining at the forefront of technological innovation. The use of augmented reality and 3D scanning enables teams to better understand actual execution conditions, align their designs with the physical reality of projects, and develop their skills in new technologies through practical on-site applications. This approach represents a genuine training opportunity for teams, promotes the adoption of digital tools, creates a positive innovation-driven culture, and reduces resistance to change when deploying new solutions. It also helps attract new talent, encourages knowledge sharing between generations, and demonstrates to clients the company\u2019s ability to adapt to a constantly evolving digital environment while differentiating itself from competitors.<\/p>\n\t\t\t\t\t<h2 data-interaction-id=\"3b9b1d2\" class=\"g-a333c7b H2-35 e-heading-base\" data-e-type=\"widget\" data-id=\"3b9b1d2\">Conclusion<\/h2>\n\t\t\t\t\t<p class=\"Body e-paragraph-base\" data-interaction-id=\"970b889\" data-e-type=\"widget\" data-id=\"970b889\">This project provides a concrete illustration of the benefits that augmented reality can bring to the As-Built Documentation (DOE) phase. Faced with demanding requirements in terms of both BIM compliance and site safety, GAMMA AR enabled the teams to work with a tool genuinely suited to field constraints.&nbsp;<br><br>Overlaying the 3D model onto reality made discrepancy identification faster and more reliable. Creating issues directly on site streamlined communication between field teams and BIM modelers without generating additional administrative tasks. Furthermore, the use of a tablet instead of smart glasses ensured that personal protective equipment (PPE) could be always worn, which was an essential requirement for working in active construction areas.&nbsp;<br><br>Beyond the results achieved on this project, this experience confirms that augmented reality can be a practical and operational tool for demanding BIM projects.
