Objectives

The primary objective is to appoint a qualified service provider to inspect, repair, load test, and recertify aircraft stackers and jacks. This ensures continued safe and reliable operation, verifies load-bearing capacity, confirms compliance with occupational health and safety legislation, manufacturer specifications, and industry standards, and provides official certification or defect remediation recommendations before equipment returns to active service.

Scope of Work

The successful bidder will conduct comprehensive inspections, functional testing, and load testing on specified stackers, including addressing identified mechanical faults such as faulty Variable Speed Drive (VSD) systems. The scope requires delivering full recertification packages that include documented evidence of accreditation, regulatory compliance, calibrated test equipment, sample certificates, defined acceptance criteria, and final reports linking serial numbers, rated capacities, and test results. Providers must also specify the exact technical standards, OEM guidelines, or regulatory frameworks applied during the recertification process.

Technical Requirements

• ISO 9001:2015 certification issued by a recognised accreditation body.
• Full compliance with the Occupational Health and Safety Act 85 of 1993 and its Driven Machinery Regulations.
• Valid calibration certificates for all testing and measuring instruments.
• Detailed documentation of load-testing equipment capabilities and test facility specifications.
• Proof of adequate Public Liability Insurance and compliance with Compensation for Occupational Injuries and Diseases (COID) requirements.
• Three verifiable references demonstrating prior stacker maintenance or recertification work.

Skills & Experience Requirements

• Proven track record in aircraft stacker recertification, with scoring weighted toward bidders who have completed two or more relevant projects.
• Competency to safely operate heavy lifting equipment, perform precise load testing, and accurately diagnose mechanical and electrical faults.
• Ability to interpret manufacturer specifications and apply correct regulatory testing methodologies.
• Skill in identifying equipment deficiencies and formulating actionable corrective maintenance recommendations.
• Capability to issue legally compliant certification documents that clearly record serial numbers, rated capacities, and test outcomes.

Unusual or Complicated Terms

• VSD Drive: Variable Speed Drive; an electronic power controller used to regulate AC motor speed and torque, essential for modern stacker performance and safety.
• Driven Machinery Regulations: South African statutory regulations under the OHS Act that mandate regular inspection, testing, and certification of powered machinery to prevent workplace accidents and ensure structural integrity.
• AFSA Expedited Arbitration: A fast-track dispute resolution mechanism administered by the Arbitration Foundation of Southern Africa, designed to resolve contractual conflicts within fifteen business days through a single appointed arbitrator.
• BBBEE Specific Goals: Preferential procurement targets mandated by South African law, awarding additional evaluation points based on black ownership, disability ownership, and women ownership percentages to promote economic transformation and historical redress.
