Making BIM as great power of construction phase

BTUK ME is an EPC contractor of the basalt fiber rebar manufacturing plant. The construction phase was critical, and leveraging the BIM models from the design stage on-site ensured their total value and consistency.

Coordination of disciplines

Numerous changes in one discipline of the BIM model should be coordinated with others to prevent outdated information in drawings and potential clashes inside a single discipline or between several disciplines.

Masterplan drawings are not actual

The site’s landscaping and utilities were carried out without an up‑to‑date master plan, the as‑built documentation for these works was provided late, and the design decisions were behind the construction works. This problem led to challenges in coordinating utilities and landscaping, resulting in delayed decision‑making on the construction site. It necessitated significant time to conduct site inspections and become acquainted with the existing conditions and construction updates.

Tracking work dynamics and project progress

A significant challenge is obtaining real-time and accurate data from the construction site for daily progress reporting. Data collection by classic report methods may lead to delays and potential inaccuracies and not always depict the visual nuances of construction progress. Maintaining consistency and standardization in daily logs across various teams and subcontractors can be difficult.

Difference between as‑built and shop drawings. Not enough data for Digital Twin

One of the customer’s requirements was the development of a Digital Twin of the plant, for which it was necessary to combine shop drawings, as‑built documentation, and real‑time sensor data. The survey of MEP systems inside the building was not carried out; as‑built documentation was developed without considering in‑place changes and insufficient data regarding rising pipes and duct elbows. As a result, the actual situation in the facilities differed from that in the drawings.

• Optimize Discipline Coordination: Implement real-time BIM updates and on-site consulting to improve collaboration across all project disciplines. Aim to reduce project clashes by 65% and increase coordination efficiency by 30% within 3 months of starting the construction phase. Ensure this approach is confirmed and agreed upon with project managers and discipline leads.

• Ensure Accurate Masterplans: Utilize aerial drone surveys and panoramic images to maintain current masterplan drawings and as-built documentation. Update masterplan drawings bi-weekly and reduce site inspection time by 40%. Achieve the first set of updates within 2 weeks and maintain bi-weekly updates throughout the construction phase, as confirmed with site management and design leads.

• Enhance Progress Tracking: Implement 360-degree photography to provide comprehensive visual documentation of construction progress. Achieve daily visual documentation of the site and resolve 90% of discrepancies identified within one week. Start weekly documentation within 1 month and review progress monthly, with approval from project stakeholders and team leaders.
  

• Develop an Accurate Digital Twin: Create a Digital Twin by integrating laser scanning data and real-time sensor information with existing documentation. Aim for 95% accuracy in as-built documentation compared to actual site conditions. Complete the initial Digital Twin development within 4 months and update it with new data every 2 months after that, as agreed upon with the engineering and BIM teams.

On-Site BIM Consulting

SIGNAX team addressed coordination challenges by providing on-site BIM consulting and training from day one. The training covered Autodesk and SIGNAX software, including Autodesk Revit, Navisworks, ACC DOCS, and SIGNAX TOOLS. The construction BIM model was continuously developed and updated, speeding up project development and reducing clashes. Deploying an Autodesk Revit server facilitated real-time BIM model synchronization, enabling multiple team members to work on different disciplines simultaneously, enhancing productivity and minimizing conflicts.

Aerial Drone Surveys and Panoramic Capturing

The Digital Survey Department conducted regular drone flights to produce orthomosaics, Digital Elevation Models (DEMs), and point clouds. These updates provided current site conditions, improved understanding, and reduced site inspection time by 40%. Aerial imagery enhanced visualization of construction progress for both on-site and remote teams. Orthomosaics corrected landscaping inaccuracies before completion, while DEMs and point clouds facilitated accurate material planning and network management.

360-Degree Imagery

360-degree imagery offered a complete visual record of the construction site, aiding in progress tracking and virtual inspections. This approach improved communication and collaboration by allowing stakeholders to visit the site virtually and discuss issues in real-time. Detailed visual data and BIM model comparisons helped identify problems early, optimize workflows, and make informed decisions to keep the project on track.

Laser Scanning and Point Clouds

SIGNAX surveyors performed two laser scanning iterations: during MEP system installation and after architectural finishing. Point clouds enabled accurate modeling of MEP systems and identified actual system positions. Data was accessible through the SIGNAX point cloud web viewer. This improved the quality of as-built documentation and allowed precise scope-of-work calculations.

Overall, these solutions led to better project coordination, more accurate data, optimized progress tracking, and enhanced communication. This comprehensive approach not only streamlined workflows but also ensured that the project was completed on time and met the highest standards of quality and efficiency.

In conclusion, integrating advanced BIM consulting, real-time data synchronization, and cutting-edge visual documentation techniques significantly enhanced the project's execution. By improving coordination, ensuring accurate and timely site information, optimizing progress tracking, and facilitating clear communication, these solutions effectively addressed the key challenges and met the customer's business needs. The successful application of these technologies not only streamlined project workflows but also ensured timely and efficient project delivery, showcasing the value of leveraging innovative approaches in construction.
