Heavy Lifting Engineers for a US company

Scope of Services

The selected candidate will work in coordination with the company's project engineers. Services may include, but are not limited to:

- Engineering analysis and documentation for heavy lift and transport load handling plans
- Development of load handling plans, including load path analysis
- Structural calculations, equipment selection, and rigging configuration
- Finite Element Analysis (FEA) and other simulations as required
- CAD modeling and drafting of lift configurations and equipment layouts
- Compliance verification with relevant US and Canadian codes, standards, and safety regulations (e.g., ASME, OSHA, AISC, etc.)

Qualification Requirements

Interested candidates should demonstrate:

- Proven experience in heavy lift, transport and rigging engineering
- Educational background with relevant discipline (Civil, Structural, Mechanical)
- Proficiency with relevant engineering software (AutoCAD, Inventor, RISA3D, MathCAD, etc.)
- Familiarity with heavy lift equipment such as hydraulic gantries, strand jacks, hydraulic skidding systems, cranes, etc.
- Ability to respond quickly to project demands with flexibility and efficiency

Software Requirements

Qualified candidates must have access to and demonstrate proficiency with the following software programs:

- Autodesk Suite (AutoCAD, Inventor, Revit, etc.)
- Microsoft Office Suite
- RISA3D v22.0
- RISASection v2.1
- MathCad Prime v10.0
- Ansys 2024 (FEA and structural simulation)

Practical and Technical Assessment (Mandatory)

All candidates are required to complete a Practical and Technical assessment designed to evaluate their engineering capabilities, critical thinking, and application of relevant standards and equipment. This assessment is a key component in the overall evaluation and scoring of proposals.

Assessment Scenario

A 250,000-pound cylindrical pressure vessel (approximately 60 feet long and 12 feet in diameter) must be:

- Offloaded from a hydraulic platform trailer using a hydraulic gantry system
- Lowered onto a slide track system
- Horizontally translated under a pipe rack with 14 feet of clearance above grade
- Upended to vertical orientation using a mobile crane in conjunction with the gantry system used to tail the vessel
- Set onto a concrete foundation

Site constraints include:

- Limited headroom under the pipe rack
- Limited space for crane setup adjacent to the upending area
- Soil bearing capacity of 3,500 psf
- No overhead obstructions other than the pipe rack

Required Deliverables

Each candidate shall develop and submit a complete engineering and lift plan package that addresses all five steps above. Deliverables must include:

1. Lift Sequence Narrative

· Detailed step-by-step description of each phase of the operation

· Identification of critical lifts and transitions (e.g., from gantry to crane)

· Discussion of site constraints, setup logistics, and safety precautions

2. Engineering Calculations

· Rigging configuration loads and capacity checks

· Hydraulic gantry and crane selection and justification

· Ground bearing pressure and support analysis for equipment

· Sliding system design or configuration

· Upending load sharing and stability analysis during transition phase

3. Drawings and Diagrams

· Plan and elevation views of each phase of the lift

· Equipment layout including gantry, crane, slide path, and foundation

· Load paths, rigging geometry, and CG location

· Schematic of upending transition (combined lift)
