Construction Workout Schedule
Per Week
Pre-Bridge:
- 1 Intense Running
- 1 Team Game Day
- 1-2 Individualized Cardio
Post-Bridge:
- T/T Fieldhouse
- M/W Brown Hallway
- Quality Control
- Design Team
- On time completion of all documentation
- Pre-submittal
- Setbacks:
- Fabrication (tabs vs. washers, member length, welding time)
Budget
3 Components:
- Overall Schedule
- WBS
- Construction/ Workout Schedule
Analysis/Modeling Cont'd.
- RISA Modeling - consult experts for design review
- Use resources - professors on campus
- Have multiple skilled users - assign model reviewer
- RISA - Symmetrical
- Must add deflection accounting for maximum tolerance
- P-delta Effects
- Clarifications
- 70% practice Load Test
- Re-build - model changes
- Check required distances (weld clearances)
Project Constraints
Competition Scoring

Overall Performance:
= Construction Economy (Cc) +
Structural Efficiency (Cs)
- Structure
- Member Size
- Deflection
- Accessibility
Project Overview
- Fabrication Failure
- Quality control
- Insufficient Modeling
- Added Cross Bracing
- Lateral Stiffening
- Construction time:
- Raw time: 15 minutes 18 seconds
- Penalties: 2 - 15 second penalties
- Total construction time: 15 minutes 48 seconds.
- Weight: 145
- Clear distance penalty - 50lbs
- Deflection: loss of structural integrity - 1150lbs
- 46% of the total load
- Construction time: Used results from springfest 1.0
- Weight: 149lbs
- Deflection: Structural failure - 1750 lbs
- 70% of the total load
Challenge:
- Design and Fabricate a 1:10 scale steel bridge prototype for the 2015 ASCE/AISC Student Steel Bridge Competition
Mission:
- Minimize: weight, deflection, construction time
Overhead Truss
Fabrication
- Benefits:
- small amount of members
- efficient connections
- Ideal weight to deflection ratio
Dovetails
- Sent out for fabrication
- Welded to connections
Main Truss Members
Connections
Dove-tail Connections
