* Excavated or Elevated structure Curve Geometry Control
* 3D modeling and FEA for specific structural elements
* Integrated Shop Drawing for Construction Risk Management

Specialized Services


BrIM (Bridge/Building Information Management), 3D Integrated Shop Drawing
Utilizing creativity and state-of-the-art 3D engineering technology. Have years of experience involved in large structural construction projects.

Curved Structural Geometry Control
1. Specialized in structural Railroad and Highway clothoid and y=kx^3 cubic spline railroad transition curve.
2. Clearance Envelop analysis
3. Elevated structure Shop drawing geometry control
4. Interchange geometry design

Rapid 3D modeling and analysis
Use analysis programs: SAP2000, COSMOS to engineer detailed connections and construction demand analysis. Capable of rapid modeling and performing analysis in fatique, large discplacements and nonlinear structural behavior, which allows us to provide great benefits to fast pace construction schedules.

Precise Geometric Control
Able to apply in house calculation engines streamlined with AutoDesk and Solidworks tools, creating accurate geometry control and visual modeling for clash detection and presentation. This is essential for the best constructability and risk management.

From preliminary designs to 3D virtual construction, our work is accurate and precise, with knowledge bridging the gap between design and construction. Our innovation stems from the traditional and the modern, insuring that your design is free from congestion and optimized for constructability.


3D Integrated Shop Drawing
1. Build true scale 3D model from design drawings
2. Create construction sequence simulation
3. Optimize rebar placement, perform conflict verification and resolution
4. Create specific software tool and customize for linkage to database for team collaboration
4. Reinforcing Steel Shop drawing Service
5. Steel Structure Shop drawing Service
6. Special detail 3D casting model and geometry definition

Bridge Engineering Design and Construction
1. Perform Preliminary and detail Highway and Bridge Design
2. Perform Seismic modeling, analysis, pre & post processing
3. Pre-cast segmental 3D geometry control
