Objectives

The primary objective is to conduct a comprehensive 36-month statutory inspection, maintenance, overhaul, and recommissioning of Boiler 1 (heavy fuel oil-fired) at the designated hospital facility. The work aims to ensure full compliance with national boiler safety regulations and occupational health standards, restore optimal operational efficiency, and guarantee safe steam production through certified inspections and component replacements.

Scope of Work

The contractor will execute a multi-phase service covering:

• Complete removal, inspection, pressure testing (1.25× design pressure), overhaul, and reinstallation of all boiler valves using specified materials and OEM components.
• Thorough internal and external cleaning of fire tubes, water sides, furnace areas, and boiler shell, including acid washing and corrosion removal.
• Coordination of third-party Authorized Inspector assessments, encompassing magnetic particle inspection, ultrasonic thickness measurements, and hydraulic pressure testing.
• Replacement of up to 102 fire tubes meeting minimum thickness specifications.
• Comprehensive burner servicing, including nozzle replacement, oil pump and filter maintenance, control calibration, and installation of new water level protection valves.
• Electrical and instrumentation upgrades, including panel cleaning, contactor/breaker replacement, and calibration of pressure, temperature, and flow gauges.
• Feed water system maintenance, hot well tank repair/coating, and complete water treatment plant and chemical dosing system servicing, flushing, and recalibration.
• Full boiler commissioning, safety valve lift testing, automated/manual operation validation, and submission of detailed technical, commissioning, and handover reports.
• Site clearance and environmentally compliant disposal of all removed materials and waste.

Technical Requirements

• Strict adherence to national Boiler Regulations and the Occupational Health and Safety Act.
• Mandatory use of Original Equipment Manufacturer (OEM) parts exclusively for critical components.
• All pressure tests must be conducted at 1.25 times the boiler’s design pressure for a minimum of one hour.
• Gaskets must be Klingerite steel-reinforced, graphite-coated; bolt assembly requires copper slip application.
• Calibration certificates for all installed pressure and measurement instruments must be provided.
• Every major phase requires witnessed sign-off by the client’s Chief Artisan and Chief Engineer, with detailed photographic and written documentation submitted throughout.
• Final output must include a complete AIA certification package, updated boiler register entries, and formal commissioning/handover documentation within stipulated timeframes.

Skills and Qualifications Requirements

• Valid CIDB Grading: 1ME (Mechanical Engineering).
• Active Central Supplier Database (CSD) registration and current COIDA Letter of Good Standing.
• Verified Broad-Based Black Economic Empowerment (B-BEE) status documentation.
• Demonstrated experience in healthcare facility boiler maintenance, supported by previous delivery notes or service records.
• Proven technical capability in mechanical overhauling, pressure vessel testing, burner dynamics, instrumentation calibration, and water treatment system management.
• Ability to liaise effectively with government-appointed inspectors and hospital engineering leadership.
• Compliance with all returnable administrative forms, including bidder disclosures and preference point claim submissions.

Explanation of Unusual/Complicated Terms

• AIA (Authorized Inspector): A state-accredited professional mandated by law to inspect, test, and certify pressure vessels like boilers. Their approval is legally required before the equipment can operate safely.
• OEM Parts: Components manufactured by the original equipment maker (specifically John Thompson). Using non-OEM alternatives is prohibited to preserve structural integrity and regulatory compliance.
• CIDB 1ME: A foundational contractor grading issued by the Construction Industry Development Board, certifying competence in mechanical engineering construction and maintenance works.
• 80/20 Preference Point System: A procurement scoring model where eighty percent of the total evaluation score is based on competitive pricing, and twenty percent is allocated to socio-economic goals, specifically prioritizing South African-owned enterprises.
