BIM for Precast - Models Connections and Documentation

1. BIM for Precast

2. Precast planning and layout with conventional methods can be costly and challenging for: • Concrete Contractors Site Engineers • Pre-casting • Manufacturing • Firms Structural Designers

3. Inaccuracies in coordination Greater drawing errors due to lack of visualization Higher modifications / rework Costly material wastage and hiccups in construction process Paper-based or 2D CAD processes are often inaccurate or error-prone leading to: Let us understand the specific challenges for precast using legacy methods.

4. 2D conventional precast techniques pose the following challenges: • Design errors • with 2D CAD techniques leads to reduced constructability Inaccurate or incomplete reports for BBS with CAD-based drawings • Uncoordinated • shop drawings • lead to inaccurate casting and material wastage Higher field errors lead to greater delivery & erection time

5. Precast concrete design, manufacturing, scheduling, and installation becomes seamless with BIM processes and tools.

6. 4 Ways that BIM can help Precast

7. Faster generation of reports based on clash-free and coordinated 3D models 1 • Quick and accurate report creation through coordinated 3D BIM models for manufacturing, and installation. • Coordinated reports for precast planning and layouts • Extraction of quantities from bar bending schedules and bar lists through a coordinated 3D BIM model. • Typical set of structural elements from clash-free BIM models, with unique ID and erection ID for further coordination.

8. 2 Typical list of structural elements using BIM Coordinated BIM models help in publishing a typical list of structural elements with respect to size and shape which help: Detailed list of structural members for factory production • Factories to save on reusable moulds and continue production in respective batches. • Save cost and time for overall production process in factories.

9. Extraction of model-based shop drawings for improved casting efficiency 3 • Production of a fully coordinated 3D Rebar model with documentation to build a comprehensive document set. • Generate accurate shop drawings with BBS • Quick extraction and edit of shop drawings from BIM models. • Detailed BBS (Bar Bending Schedule) from coordinated BIM models for precise casting.

10. Faster building erection with Precast concrete modeling and detailing 4 • Visualization of erection sequences with unique ID with precast element connections and joint design for better assembly. Reduce onsite errors for faster erection • Precise mapping of construction activity planning and elements related to each activity with the use of BIM. • Swift onsite erection, cost and time savings with accurate component placement, precise erection orders, and planned logistics for speedy construction.
