BIM
for Precast
Precast planning and layout with conventional methods can be costly and challenging for:
Pre-casting Manufacturing Firms
Structural Designers
Concrete Contractors
Site Engineers
Paper-based or 2D CAD processes are often inaccurate or error-prone leading to:
Inaccuracies in coordination Greater drawing errors due to lack of visualization Higher modifications / rework Costly material wastage and hiccups in construction process
Let us understand the specific challenges for precast using legacy methods.
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
Precast concrete design, manufacturing, scheduling, and installation becomes seamless with BIM processes and tools.
4 Ways that BIM can help Precast
1
Faster generation of reports based on clashfree and coordinated 3D models
Quick and accurate report creation through coordinated 3D BIM
Coordinated reports for precast planning and layouts
models for manufacturing, and installation. 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.
2
Typical list of structural elements using BIM
Coordinated BIM models help in publishing a typical list of
Detailed list of structural members for factory production
structural elements with respect to size and shape which help: Factories to save on reusable moulds and continue production in respective batches. Save cost and time for overall production process in factories.
3
Extraction of model-based shop drawings for improved casting efficiency
Production of a fully coordinated 3D Rebar model with
Generate accurate shop drawings with BBS
documentation to build a comprehensive document set.
Quick extraction and edit of shop drawings from BIM models.
Detailed BBS (Bar Bending Schedule) from coordinated BIM models for precise casting.
4
Faster building erection with Precast concrete modeling and detailing
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.
Coordinated 3D structural model at LOD 450 saves cost and time for office building. An accurate, information-packed, and clash-free 3D Revit structure model at LOD 450 reinforced with Rebar modeling saved cost and time for a precast manufacturing project.
