Module 5: Case Studies & Practical Workshops
This module bridges theory and real-world application through hands-on projects, software training, and industry exposure. Participants will develop practical skills in precast design, modeling, and quality control while analyzing actual project challenges.
Group Project: Design a Precast Parking Structure or Residential Module
Objective: Apply precast design principles to a functional structure while optimizing modularity, connections, and logistics.
Design Phase:
Structural Layout:
Parking Structure: Use double tees, columns, and shear walls for a 4-level layout.
Residential Module: Volumetric units (e.g., bathroom/kitchen pods) with MEP integration.
Connection Design:
Specify shear keys, embeds, and moment-resisting joints per PCI/AISC standards.
Sustainability Integration:
Incorporate recycled aggregates, carbon-cured concrete, or photovoltaic cladding.
Logistics & Erection Plan:
Lifting Analysis: Identify pick points and crane locations using load charts.
Transport Strategy: Plan routes for oversized elements (e.g., double tees).
Deliverables:
Technical Drawings: Detailed plans, elevations, and connection details.
Presentation: Justify design choices (e.g., why hollow-core slabs over solid panels).
Software Demo: RAM Elements, Tekla, or Allplan Precast
Objective: Train participants in industry-standard tools for precast modeling, analysis, and documentation.
RAM Elements (Bentley):
Analysis Features:
Finite element modeling (FEM) for precast beams, columns, and walls.
Load combinations per ACI 318 or Eurocode.
Use Case: Simulate a parking structure’s lateral load resistance.
Tekla Structures (Trimble):
BIM Integration:
Create 3D models with precast-specific components (e.g., embeds, lifting loops).
Generate shop drawings and CNC files for molds.
Clash Detection: Resolve conflicts between rebar and ducts.
Allplan Precast (Nemetschek):
Automated Reinforcement:
Optimize rebar layouts for production efficiency.
4D Scheduling: Link elements to construction timelines.
Workshop Task:
Model a precast column in Tekla, then run a connection analysis in RAM Elements.
Site Visit/Virtual Tour: Precast Plant or Installation Site
Objective: Observe real-world production, handling, and erection processes.
Precast Plant Tour:
Production Line:
Batching → Casting (SCC vs. vibrated) → Curing (steam tunnels) → Demolding.
Quality Control:
Witness compressive strength tests and PCI compliance checks.
Installation Site Visit:
Erection Sequence:
Crane setup → Temporary bracing → Grouting of connections.
Safety Protocols:
Exclusion zones, fall protection, and lift planning.
Virtual Alternative:
360° VR Walkthrough: Explore a plant via platforms like Matterport or BIM 360.
Live Q&A: Interact with plant managers/engineers.
Key Takeaways
Design Practice: Participants gain confidence in precast structural systems.
Software Skills: Direct experience with tools used by top firms.
Industry Exposure: Links classroom learning to real-world workflows.
Example Project: A 2023 student group reduced material waste by 15% in their parking design using Allplan’s optimization tools.
