Tender Summary: Conduct Data Logging

Objectives

The primary objective is to perform comprehensive electrical network data logging at Mbongolwane Hospital to assess power quality and grid stability. The project aims to identify electrical anomalies, with a specific focus on incoming harmonics, and deliver a detailed analytical report containing evidence-based findings and engineering recommendations to ensure safe and efficient hospital power distribution.

Scope of Work

• Supply, safely connect, and operate data loggers on the low-voltage (LV) side of the hospital’s essential electrical panels.
• Configure loggers to record data at ten-minute intervals over an agreed duration, which may be extended by the supervising engineer.
• Develop a connection methodology, conduct hazard identification, and implement mitigation measures to ensure zero disruption to ongoing hospital operations.
• Download all raw data and compile a comprehensive analysis report within seven working days of meter removal.
• Facilitate a compulsory kick-off meeting, equipment installation, and a final close-out presentation. Travel reimbursements are capped at a 300-kilometre radius.
• No work may commence without explicit prior authorization from the Facility Manager.

Technical Requirements

• Metering accuracy must be within five percent. All equipment must be pre-approved by the facility engineer before deployment.
• Loggers must capture voltages, currents, frequency, real and reactive power, power factor, maximum demand, voltage dips/swells, and harmonics. Emphasis must be placed on externally sourced harmonics rather than internally generated ones.
• Data analysis must utilize NRS 048 guidelines as the primary benchmark for power quality assessment.
• All activities must comply with the Occupational Health and Safety Act, SANS 10142 (Code of Practice for Wiring of Premises), and other relevant electrical standards.
• Deliverables include a specialist-signed analytical report, a compact disc containing all raw data files, and documented hazard mitigation strategies.

Skills and Qualification Requirements

• Service providers must hold SANAS accreditation (Grade 2EB, 2EP, or higher) to validate testing and calibration competency.
• Bidders must submit verifiable proof of successfully completing at least three similar projects in private or public health facilities.
• The execution team must include skilled technicians for safe equipment installation and a qualified electrical specialist authorized to sign the final analysis report.
• Providers must demonstrate immediate availability of compatible data logging hardware and proprietary analysis software.
• Administrative compliance is mandatory, including Central Supplier Database registration, valid tax clearance, B-BBEE verification, and submission of all standard bidding declaration forms.
• Twenty preference points are allocated to enterprises that are at least fifty-one percent owned by Black women, in line with national procurement transformation policies.

Glossary of Specialized Terms

• SANAS: South African National Accreditation System; certifies that testing and calibration laboratories meet international competency standards.
• NRS 048: South African national standard defining acceptable power quality limits and harmonic distortion levels in electrical distribution networks.
• SBD Forms: Standard Bidding Document templates mandated by the South African government for vendor declarations, compliance checks, and preference claims.
• 80/20 Preference Point System: A procurement scoring model where eighty points are awarded for competitive pricing and twenty points for designated social goals, such as black female ownership.
