How ID sequencing in BIM precast models drives efficiency in onsite assembly

impact of id sequencing in bim precast models
ID sequencing of precast models using BIM, ensures precise onsite assembly, efficient tracking, and improved communication. The systematic use of unique identifiers leads to improved project outcomes and cost-effective construction workflows.

Precast modeling with BIM supports the creation of accurate and detailed digital representations for precast concrete. ID sequencing is vital in precast modeling and the use of BIM processes and tools ensure accurate onsite assembly for precast and prefab manufacturers. A systematic identification and sequencing of precast elements with precast modeling and detailing enables effective and efficient tracking, operations, and flawless assembly. It augments collaboration, reduces on-site difficulties, and ensures uninterrupted integration of precast components to optimize construction.

By clarifying the strategic use of identification sequencing of precast elements, this article aims to educate prefab and precast manufacturers on how to enhance accuracy, improve project coordination, and simplify precast assembly to ensure the integration of precast elements within a wider framework.

Role of BIM-based precast ID sequencing for onsite assembly installation

Implementing ID sequencing in precast 3D models within BIM enhances onsite assembly. Assigning unique identifiers creates a seamless construction process to ensure accurate precast element placement and error reduction. This systematic approach improves efficiency, lowers onsite assembly time, and drives collaboration between construction teams, leading to cost-effective workflows.

ID sequencing within precast models also manages data effectively within the BIM framework. Assigning unique identifiers for each precast element helps organize, track, and analyse complex data. The improved collaboration between project participants drives error-free onsite assembly leading to a seamless integration of precast elements in the BIM framework. This causes an overall improvement in efficiency, reduction in errors, and project coordination.

Coordinating onsite precast construction with ID sequencing

Integration of ID sequencing with construction schedule

Implementation of unique IDs for precast elements can ensure timely delivery and assembly of precast elements. Integrating a BIM methodology into construction employs a well-coordinated workflow. Each precast element is assigned a unique identifier, logistics data, and a coordinated workflow that connects with project schedules.

Meticulous tracking reduces delays, enhances schedule precision, and drives effective and efficient construction. The result leads to organized and timely delivery and assembly of precast components that contributes to the overall success of the project.

Onsite verification processes

  • Quality checks based on ID sequences: Quality checks for Precast Elements are augmented based on ID sequences. Rigorous inspections can be established for each element based on unique IDs. Construction teams can track, validate, and guarantee the quality of BIM-driven precast components. BIM-driven precast sequencing ensures accountability, lowers errors, and delivers a greater level of construction quality to deliver reliable and superior structures.

  • Addressing discrepancies during assembly: Addressing ambiguities during precast assembly can be managed with unique ID’s assigned for precast elements. Distinct identifiers improve identification and tracking of precast elements. Any ambiguities can be located and rectified leading to streamlined assembly.

    A systematic methodology reduces errors, improves quality control, and promotes effective and efficient onsite construction leading to fewer disruptions and improvements in overall project quality.

Precast success stories using ID sequencing

A precast contractor from UAE specializing in precast manufacturing teamed up with Hitech CADD Services for a residential project in the UAE. They shared AutoCAD drawings, PDF and Excel files as input with the team. We used multiple software platforms like Revit, Navisworks, and BIM360 design to achieve desired deliverables.

With a team of 25 BIM modelers the team at Hitech CADD Services began their work between planning and design phase. The input files were carefully assessed and model optimization was achieved with object-based 3D modeling. Clash coordination was done that led to improved schedules, enhanced execution, and cost optimization. Quality checks were done for standardization. These processes led to a clash-free and coordinated BIM model in Revit for precast manufacturing and installation.

The 3D model was clash coordinated at LOD 450 with 5mm clash coordination. BBS, BOMs, and Bar Bending Schedules were determined from the precast 3D model which led to:

  • Improvements in production quality with precast shop drawings
  • Faster and accurate erection through unique IDs assigned to precast elements
  • Quick TAT within 6-8 months with 100% accuracy
  • Cost savings
