Bridge Inspection and Turnkey Repairs

Power Generation

Scope of Work:

• Performed a comprehensive inspection of a ~1,000-foot suspension bridge spanning a major waterway
• Utilized ground-based, elevated walkway, and rope-access techniques to evaluate hard-to-reach areas
• Benchmarked findings against prior inspection reports to identify changes and new deficiencies
• Classified deficiencies by priority level to guide repair urgency and scope
• Performed engineering analysis and developed Standard Repair Procedures (SRPs) for identified deficiencies
• Coordinated access constraints, including railroad scheduling, live powerline limitations, and follow-up inspections
• Executed turnkey repair construction for the north half of the bridge, including demolition and repairs
• Provided construction coordination, safety planning, and on-site quality oversight

Deliverables:

• Phased inspection reports as segments of the bridge were completed
• A repair prioritization ranking assigned to each finding
• Standard Repair Procedures (SRPs) and engineering repair IFC drawings for Priority 1 deficiencies
• Construction coordination and quality assurance documentation
• Final inspection report and repair verification records

Project Highlights:

• Orbital delivered a comprehensive inspection and turnkey repair program for a 1,000-foot suspension bridge, combining rope-access inspection, structural engineering, and construction oversight to address complex access and safety challenges. The inspection identified 43 deficiencies, including multiple Priority 1 conditions such as widespread cracked welds, severe section loss in a primary truss chord, and extensive concrete spalling with exposed reinforcement. Orbital executed phased reporting to support timely decision-making and completed full demolition and repairs on the north half of the bridge. When lead-containing coatings were discovered mid-demolition, Orbital paused work, coordinated with regulatory agencies, and implemented a revised, compliant construction plan – allowing repairs to resume and conclude efficiently while maintaining safety, regulatory compliance, and structural integrity.

Coal Delivery System Modification

Power Generation

Scope of Work

• Coal fired power generation facility client faced a dilemma with their existing barge unloader only capable of unloading barges up to a specific width, limiting the type of barge that can be used in delivery
• Further complicating the delivery, the barges that fit within the constraints of the unloader are becoming less available due to age
• Orbital developed conceptual solution for a new barge unloading system that allowed for unloading jumbo barges to the existing surge bin via deck mounted Sennebogen cranes, hoppers and conveyors on a new deck barges and incline conveyors to the existing surge bin
• Once approved, Orbital executed detailed design including procurement support in equipment specification and selection, owner’s engineering and construction support

Deliverables

• General arrangement drawings and total installed cost estimates for various solutions

• Conveyor support steel drawings and foundations
• Single line diagrams, power plans, lighting plans, grounding plans, cable & conduit schedules
• Scope of work documents for construction

Project Highlights

• Project was originally deemed an “unsolvable problem” due to complexities in the design interfaces, contractual interfaces between delivery and client and limited remaining operating window for the facility. Orbital’s efficient solution allowed for the project to be authorized, and the facility is currently conducting coal unloading operations via the new unloading system. The facility operating permit has been extended since project completion making the solution benefits realized well into the future.
• Total Installed Cost (TIC) – $4MM
