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)
